Understanding the interactions between the host and pathogen is critical in implementing disease management strategies and developing resistant cultivars. This review provides an update on the interactions of apple with Alternaria alternata apple pathotype, which causes Alternaria blotch, with a brief history about the discovery of the disease and pathogen and its damage and epidemiology. The focus of the review is placed on the physiological and genetic response of the host to pathogen infection, including resistance and susceptibility, and the molecular markers associated with them. Of the response of the pathogen to the host, the emphasis is placed on the role of the selective toxins on pathogenicity and their genetic controls and regulations. The review ends with a perspective on future directions in the research on the apple-A. alternata pathosystem in the era of genomics and post genomics, particularly on how to identify candidate genes from both host and pathogen for potential genetic engineering for disease resistant cultivars.}, number={3}, journal={CRITICAL REVIEWS IN PLANT SCIENCES}, author={Li, Ying and Aldwinckle, Herbert.

Differences in cultural and conidial morphology were observed between the isolates from Australia and the USA. Phylogenetic relationships were determined based on three gene regions: the ribosomal DNA (rDNA) internal transcribed spacer 1 (ITS1–5∙8S–ITS2), 28S large subunit (LSU) nuclear rDNA and β‐tubulin‐2. Greeneria uvicola isolates were clearly differentiated into four groups: isolates from Australia and India; USA isolates from V. vinifera; USA isolates from M. rotundifolia; and the isolate from Costa Rica. All isolates were pathogenic on V. vinifera (cv. Chardonnay) berries although those originating from M. rotundifolia were not as aggressive as isolates from V. vinifera, irrespective of geographical origin. Sensitivity to pyraclostrobin and salicylhydroxamic acid (SHAM) was studied. Despite differences in fungicide applications, hyphal growth inhibition was not significantly different for geographical location, cultivar, tissue, year of collection or different spray regimes. For the Australian and USA isolates, fungal growth inhibition was significantly greater for pyraclostrobin than for SHAM, and was significantly greater for the combined treatment than for each of the fungicides applied singly.

The disease occurs worldwide in regions with moist growing seasons. SBFS is regarded as a serious disease by fruit growers and plant pathologists because it can cause substantial economic damage. The smudges and stipples of SBFS often result in downgrading of fruit from premium fresh-market grade to processing use.

Generally, these empirical models are based on the accumulation of hours of leaf wetness (leaf wetness duration [LWD]) from a biofix at or near the phenological growth stage petal fall, when apple flower petals senesce and drop. The models recommend timing of the initial fungicide application targeting SBFS. However, there are significant differences among SBFS forecast models in terms of biofix and the length of LWD thresholds. A comparison of models using a single input data set generated recommendations for the first SBFS fungicide application that differed by up to 5 weeks. In an attempt to improve consistency among models, potential sources for differences were examined. Leaf wetness (LW) is a particularly variable parameter among models, depending on whether on-site or remote weather data were used, the types of sensors and their placement for on-site monitors, and the models used to estimate LW remotely. When SBFS models are applied in the field, recommended treatment thresholds do not always match the method of data acquisition, leading to potential failures. Horticultural factors, such as tree size, canopy density, and cultivar, and orchard site factors such as the distance to potential inoculum sources can impact risk of SBFS and should also be considered in forecast models. The number of fungal species identified as contributors to the SBFS disease complex has expanded tremendously in recent years. A lack of understanding of key epidemiological factors for different fungi in the complex, and which fungi represent the most challenging management problems, are obvious issues in the development of improved SBFS models. If SBFS forecast models are to be adopted, researchers will need to address these issues. }, number={9}, journal={Plant Disease}, author={Cooley, D. R. and Rosenberger, D. A. and Gleason, M.

Forty apple fruit per orchard were arbitrarily sampled and colonies of each mycelial phenotype were counted on each apple. Representative colonies were isolated, cultures were purified, and DNA was extracted. For representative isolates, the internal transcribed spacer (ITS) and large subunit (LSU) regions of ribosomal DNA were amplified and sequenced. In total, 60 SBFS putative species were identified based on ITS sequences and morphological characteristics; 30 of these were discovered in the 2005 survey. Modified Koch's postulates were fulfilled for all 60 species in an Iowa orchard; colonies resulting from inoculation of apple fruit were matched to the original isolates on the basis of mycelial type and ITS sequence. Parsimony analysis for LSU sequences from both surveys revealed that 58 putative SBFS species were members of the Dothideomycetes, 52 were members of the Capnodiales, and 36 were members of the Mycosphaerellaceae. The number of SBFS species per orchard varied from 2 to 15. Number of SBFS species and values of the Margalef and Shannon indexes were significantly (P < 0.05) lower in 21 orchards that had received conventional fungicide sprays during the fruit maturation period than in 14 unsprayed orchards. Several SBFS species, including Schizothyrium pomi, Peltaster fructicola, and Pseudocercosporella sp. RH1, were nearly ubiquitous, whereas other species, such as Stomiopeltis sp. RS5.2, Phialophora sessilis, and Geastrumia polystigmatis, were found only within restricted geographic regions. The results document that the SBFS complex is far more taxonomically diverse than previously recognized and provide strong evidence that SBFS species differ in geographic distribution.

Persimmon fruit (Japanese persimmon, Diospyros kaki cv. Fuyu) were collected in November 2008 from a tree in Windsor, NC, located in the Coastal Plain. Fruit were not symptomatic on the tree but developed dark lesions after harvest. Isolations from six fruit yielded seven isolates of Colletotrichum acutatum J. H. Simmonds. After incubation at 25°C under continuous light for 15 days on potato dextrose agar (PDA), all isolates had gray aerial mycelium, but the inverse sides of the plates of six isolates were maroon and one was beige. Masses of salmon-colored conidia were formed first in the center of the colonies, then were observed scattered across the colonies in older cultures. Conidia were hyaline, one-celled, elliptic with one or both ends pointed, and measured 8.1 to 16.3 × 3.1 to 5 μm. Setae and sclerotia were not observed. There were also dark structures measuring 1 to 10 mm that were partially embedded in the agar that contained conidia. Cultural and conidial characteristics of the isolates were similar to those of C. acutatum (3). PCR amplification was performed with the species-specific primer pair CaInt2/ITS4 (2) and genomic DNA from the original isolates and isolates obtained from inoculated fruit. An amplification product of approximately 490 bp, which is specific for C. acutatum, was observed. To fulfill Koch's postulates, persimmon fruit obtained from the grocery store were surface disinfested with 0.5% sodium hypochlorite and sterile filter paper disks dipped in conidial suspensions (1 × 105 conidia/ml) of two C. acutatum isolates (maroon and beige reverse) or sterile, deionized water were placed on the fruit. Three fruit were inoculated per treatment and the disks were placed on four locations on each fruit. Parafilm was wrapped around the diameter of the fruit to keep the filter paper disks moist and in place. Fruit were placed in moist chambers and incubated at 25°C. After 3 days, the Parafilm was removed and the fruit returned to the moist chambers. Small, dark lesions were observed on fruit inoculated with each isolate of C. acutatum when the filter paper disks were removed. Ten days after inoculation, dark lesions and acervuli with salmon-colored masses of conidia were observed on fruit inoculated with both isolates of C. acutatum and the fruit were soft. After 12 days, there were abundant masses of conidia and the inoculated areas were decayed. Control fruit remained firm and did not develop symptoms. Cultures obtained from the fruit and the conidia produced were typical of the isolates used to inoculate the fruit. C. acutatum has been reported to cause fruit rot on persimmon fruit in New Zealand (1). To our knowledge, this is the first report of C. acutatum on persimmon fruit in the United States.

In the Upper Midwest United States, however, this warning system has resulted in sporadic disease control failures. The purpose of the present study was to determine whether the warning system's algorithm could be modified to provide more reliable assessment of SBFS risk. Hourly LWD, rainfall, relative humidity (RH), and temperature data were collected from orchards in Iowa, North Carolina, and Wisconsin in 2005 and 2006. Timing of the first appearance of SBFS signs was determined by weekly scouting. Preliminary analysis using scatterplots and boxplots suggested that cumulative hours of RH ≥ 97% could be a useful predictor of SBFS appearance. Receiver operating characteristic curve analysis was used to compare the predictive performance of cumulative LWD and cumulative hours of RH ≥ 97%. Cumulative hours of RH ≥ 97% was a more conservative and accurate predictor than cumulative LWD for 15 site years in the Upper Midwest, but not for four site years in North Carolina. Performance of the SBFS warning system in the Upper Midwest and climatically similar regions may be improved if cumulative hours of RH ≥ 97% were substituted for cumulative LWD to predict the first appearance of SBFS. }, number={8}, journal={PLANT DISEASE}, author={Duttweiler, K.

The cultivars VA 98R and NC‐V 11 were planted beginning in early May through early June during each year with reflectance and the percentage of pods at optimum maturity (percentage of pods with brown or black mesocarp color) determined in mid‐September.

The serious and sometimes irreparable ecological and economic damage of exotic pathogens, such as Cryphonectria parasitica, Ophiostoma novo-ulmi, and Phytophthora ramorum, the causal agents of chestnut blight, Dutch elm disease, and Sudden Oak Death, respectively, are amply documented (1,6,42). An estimate of annual losses for exotic plant pathogens is $21 billion dollars (32). The Plant Protection and Quarantine (PPQ) (Sidebar 1) division within the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (USDA-APHIS) has the goal of safeguarding agriculture and natural resources from the risks associated with the entry, establishment, and spread of exotic pathogens. Two important components of the APHIS-PPQ mission are risk analysis and pest detection. A key goal of the risk analysis program is to identify exotic pest pathways and to assess the risks these exotic pests pose to plants and plant products as well as to the environment. Three types of risk assessments that evaluate the probability of the introduction and establishment of exotic plant pests are pathway analysis, organism pest risk assessment, and commodity risk assessment. The PPQ pest detection program and its state cooperators provide a continuum of pest surveillance, from offshore preclearance programs through port inspections, to surveys in rural and urban sites across the United States. The Center for Plant Health Science and Technology (CPHST) and the Cooperative Agricultural Pest Survey (CAPS) programs are instrumental in APHIS-PPQ’s pest detection programs. CAPS is responsible for supplying a means of detection, documentation, and rapid dissemination of information regarding the survey of regulated significant plant pests and weeds in the United States. The survey information gathered by CAPS is entered into a central database known as National Agricultural Pest Information System (NAPIS). CPHST, headquartered in Raleigh, NC, is a multi-program scientific support organization for PPQ. One way CPHST scientists help facilitate the APHIS-PPQ activities of risk analysis and pest detection is by mapping the potential introduction and establishment of exotic pathogens in the United States. These maps are the result of pathogen-specific information analyses, including climate, pathogen distribution, host distribution, and trade. Given its influence on pest phenology, reproduction, dispersion, and overwintering survival, climate is a critical component for the geographic assessment of potential pathogen distribution. A large number of climate-based risk mapping systems, such as CLIMEX, BIOCLIM, and GARP, have been used for pest risk analysis (3,10,38,44).

Sharpshooter species were assessed for the presence of X. fastidiosa in the field. Leafhoppers were trapped in three vineyards in the eastern Piedmont and one vineyard in the northeastern Coastal Plain in 2004 and 2005. Four insects were identified as most abundant: Oncometopia orbona, Graphocephala versuta, Paraphlepsius irroratus, and Agalliota constricta.

Transmission experiments demonstrated that both O. orbona and G. versuta have the ability to transmit X. fastidiosa to grape. These vectors are likely to be important in all winegrowing regions of the Southeast, because their presence has been documented throughout the southern states.

From this collection, 155 isolates of G. cingulata (93 from fruit, 61 from leaves, and 1 from buds), 42 isolates of C. gloeosporioides from fruit, and 14 isolates of C. acutatum (10 from fruit and 4 from leaves) were studied using mitochondrial (mt)DNA restriction fragment length polymorphism (RFLP) haplotypes. A subset of 24 isolates was studied by examining the sequence of a 200-bp intron of the glyceraldehyde 3-phosphate dehydrogenase (GDPH) nuclear gene. In addition, 98 isolates were tested for pathogenicity on leaves of cvs. Gala and Golden Delicious in the greenhouse, and 24 isolates were tested for pathogenicity on fruit of cv.

Five morphological types and six VCGs were identified among 74 and 36 isolates of C. gloeosporioides, respectively. Three morphological types and four VCGs were identified among 74 and 23 isolates of C. acutatum, respectively. Seven different mtDNA RFLP haplotypes were observed within isolates of G. cingulata, two within isolates of C. gloeosporioides, and two within isolates of C. acutatum. Phylogenetic trees, inferred based on maximum likelihood and maximum parsimony methods using the intron sequence, produced similar topologies. Each species was separated into distinct groups. All isolates tested were pathogenic on fruit, though only isolates with specific VCGs and haplotypes were pathogenic to leaves. Vegetative compatibility was a better tool than molecular characters for distinguishing isolates of G. cingulata pathogenic on both leaves and fruit from the ones pathogenic only on fruit. Isolates of G. cingulata capable of causing both GLS and bitter rot were included in haplotypes and groups based on the sequence analysis of the 200-bp intron that also included isolates capable of causing bitter rot only. Additionally, isolates of G. cingulata from the United States and Brazil which cause GLS were included in different haplotypes and sequence analysis groups. Therefore, one hypothesis is that isolates of G. cingulata from the United States capable of causing both GLS on foliage and bitter rot on fruit may have arisen independently of Brazilian isolates of G. cingulata capable of causing both GLS and bitter rot, and the two groups of isolates may represent distinct populations. }, number={9}, journal={PHYTOPATHOLOGY}, author={Gonzalez, Eugenia and Sutton, Turner B. and Correll, James C.}, year={2006}, month={Sep}, pages={982–992} } @article{partridge_sutton_jordan_2006, title={Effect of environmental factors and pesticides on mycoparasitism of Sclerotinia minor by Coniothyrium minitans}, volume={90}, ISSN={["1943-7692"]}, DOI={10.1094/PD-90-1407}, abstractNote={ The effects of soil temperature and moisture, and nine pesticides commonly used in peanut production, on the mycoparasitic activity of Coniothyrium minitans on sclerotia of Sclerotinia minor were evaluated. In vitro mycelial growth and conidia germination of C. minitans were sensitive to azoxystrobin, chlorothalonil, fluazinam, pyraclostrobin, tebuconazole, and diclosulam. C. minitans survived and infected sclerotia of S. minor in the presence of azoxystrobin, chlorothalonil, diclosulam, fluazinam, flumioxazin, S-metolachlor, pendimethalin, pyraclostrobin, and tebuconazole. Mycoparasitic activity was reduced by all pesticides except S-metolachlor compared with the nontreated control. Optimum conditions for infection of sclerotia were temperatures from 14 to 22°C and soil moisture from -0.33 to -1 kPa × 102. Mycoparasitic activity of C. minitans remained high (98% sclerotia infected) at temperatures ranging from 14 to 22°C, but decreased at temperatures above 28°C. Viability of sclerotia was inversely related to the proportion infected by C. minitans (r = -0.9963, P = 0.001). Mycoparasitic activity also declined when soil moisture was greater than -1 kPa × 102 or less than -0.10 kPa × 102. These results indicate that C. minitans should not be applied when temperatures exceed 28°C, during extremes in soil moisture, or when there is a high risk of contact with pesticides before it becomes established in the soil. }, number={11}, journal={PLANT DISEASE}, author={Partridge, D.

The effectiveness of Coniothyrium minitans, a mycoparasite of sclerotia of Sclerotinia spp., was studied in a 5-year field experiment and in eight short-term experiments in northeastern North Carolina. The 5-year experiment was initiated in November 1999 to evaluate the effectiveness of repeated soil applications of C. minitans (commercial formulation, Contans WG) at 2 and 4 kg ha-1 in reducing Sclerotinia blight. In addition, individual commercial peanut fields were selected in 2001 and 2002 to evaluate a single application of C. minitans at 4 kg ha-1. No differences were found between the 2 and 4 kg ha-1 rates of C. minitans in reducing Sclerotinia blight. In 2002, there was less disease in plots receiving applications of C. minitans for either 1 or 3 years compared with the nontreated control; whereas, in 2003, C. minitans applications for 1, 2, or 3 years reduced disease and the number of sclerotia isolated from soil. A single application of C. minitans reduced sclerotia in only two of the eight short-term experiments. The integration of consecutive years of soil applications of C. minitans at 2 kg ha-1 with moderately resistant cultivars and fungicide applications may aid in the management of Sclerotinia blight in peanut. }, number={7}, journal={Plant Disease}, author={Partridge, D.

The model is designed primarily for use in forecasting pathogens that do not have extensive epidemiological data. Most existing infection models require a background epidemiological data set, usually including laboratory estimates of infection at multiple temperature and wetness combinations. The model developed in this study can use inputs based on subjective estimates of the cardinal temperatures and the wetness duration requirement. These inputs are available for many pathogens or may be estimated from related pathogens. The model uses a temperature response function which is scaled to the minimum and optimum values of the surface wetness duration requirement. The minimum wetness duration requirement (Wmin) is the number of hours required to produce 20% disease incidence or 5% disease severity on inoculated plant parts at a given temperature. The model was validated with published data from 53 controlled laboratory studies, each with at least four combinations of temperature and wetness. Validation yielded an average correlation coefficient of 0.83 and a root mean square error of 4.9 h, but there was uncertainty about the value of the input parameters for some pathogens. The value of Wminvaried from 1 to 48 h and was relatively uniform for species in the genera Cercospora, Alternaria, and Puccinia but less so for species of Phytophthora, Venturia, and Colletotrichum. Operationally, infection models may use hourly or daily weather inputs. In the case of the former, information also is required to estimate the critical dry-period interruption value, defined as the duration of a dry period at relative humidities <95% that will result in a 50% reduction in disease compared with a continuous wetness period. Pathogens were classified into three groups based on their critical dry-period interruption value. The infection model is being used to create risk maps of exotic pests for the U.S. Department of Agriculture's Animal Plant Health and Inspection Service.}, number={1}, journal={Phytopathology®}, publisher={Scientific Societies}, author={Magarey, R.

In early years, P. graminis f. sp. tritici was common, but the frequency of P. graminis f. sp. tritici in aeciospore collections declined to a low of 4% in the 1980s, whereas P. graminis f. sp. secalis increased to 96%. After 1990, the frequency of P. graminis f. sp. tritici increased and P. graminis f. sp. secalis declined in aecial collections, possibly indicating a changing proportion of P. graminis f. sp. secalis and tritici on wild grasses near barberry bushes. Diversity of races among uredinial collections of P. graminis f. sp. tritici from wheat in Minnesota declined sharply from 1912 to 1930 and remained low to 2002. Although the races of P. graminis f. sp. tritici most common in uredinial collections also were most common in the aecial collections in five of nine decades from 1912 to 1999 as well in the years 2000 to 2002, the diversity of races was greater among aecial than uredinial collections.

Over 500 million bushes were destroyed nationally during the program, approximately 1 million in Minnesota. Some sites in Minnesota where barberry bushes were destroyed remained in the “active” class when eradication was phased out in the 1980s. Active sites were defined as those on which there was still a possibility of emergence of barberry seedlings or sprouts arising from the parent bush. In the present study, from 1998 to 2002, 72 of the approximately 1,200 active sites in Minnesota were surveyed. Areas within 90 m of mapped locations of previously destroyed bushes were searched carefully at each site. Reemerged barberry plants were found on 32 sites. The reproductive status and GPS coordinates were recorded for each reemerged bush. More than 90% of the barberry bushes were found in counties with less than 400 ha of wheat per county, mostly in southeastern Minnesota, but one bush was found in a major wheat-producing county in northwestern Minnesota. Reemergence of barberry may serve as a source of new wheat stem rust races in future epidemics. }, number={2}, journal={PLANT DISEASE}, author={Peterson, PD and Leonard, KJ and Miller, JD and Laudon, RJ and Sutton, TB}, year={2005}, month={Feb}, pages={159–163} } @article{bell_ranney_eaker_sutton_2005, title={Resistance to fire blight among flowering pears and quince}, volume={40}, number={2}, journal={HortScience}, author={Bell, A.

Morphological characters and vegetative compatibility groups (VCGs) were used to determine diversity within the species. The relative frequencies of the morphological types found within each species in each orchard were also determined. G. cingulata was the predominant species associated with bitter rot in the three orchards and Glomerella leaf spot in the Gala orchard. In the three orchards, different morphological types were observed within isolates of G. cingulata and Colletotrichum acutatum, but not within isolates of Colletotrichum gloeosporioides. Isolates of C. gloeosporioides were not found in the orchard of cv. Granny Smith in Lincoln County. In the other two orchards, C. gloeosporioides represented the lowest proportion of the population. Three VCGs were found among isolates of G. cingulata (VCG-1, 2, and 6), two among isolates of C. gloeosporioides (VCG-9 and 10), and two among isolates of C. acutatum (VCG-15 and 16).

Seven banana genotypes, ranging from susceptible to resistant, were used to evaluate the method. Banana plants from tissue culture, grown in 0.4-liter Styrofoam cups containing sterilized sand as substrate, were maintained in the greenhouse for 4 weeks before inoculation. Two hundred burrowing nematodes, reared in monoxenic carrot-disk culture, were used as inoculum for each container. Plants were kept in the greenhouse for an additional 8 weeks at about 27°C and 80% relative humidity after inoculation. Burrowing nematodes reproduced well in the susceptible cultivars False Horn, Grande Naine, Valery, and Lacatan, whereas the reproductive fitness was very low in the resistant cultivars Pisang Jari Buaya and Yangambi. An intermediate reaction between these two groups was observed with Pisang mas. A similar trend was obtained in a follow-up field test, which indicated that the method is accurate and reliable. Assessments of total-root necrosis associated with this pathogen were also comparable between greenhouse and field conditions. However, nematode effects on the roots were more severe in the greenhouse test than in the field. In spite of low nematode reproductive fitness, root necrosis was relatively high in the two resistant cultivars tested in the greenhouse trial. }, number={6}, journal={PLANT DISEASE}, author={Marin, DH and Barker, KR and Kaplan, DT and Sutton, TB and Opperman, CH}, year={2000}, month={Jun}, pages={689–693} } @article{marin_barker_sutton_2000, title={Efficacy of 'ABG-9008' against burrowing nematode (Radopholus similis) on bananas}, volume={30}, number={1}, journal={Nematropica}, author={Marin, D.

No mycelial growth was observed on russetted areas of the cuticle that are considered impermeable. Ursolic acid and n-alkanes were the most prominent components of the epicuticular waxes of the cultivars or selections evaluated. Although there were differences in the relative proportions of these compounds among the cultivars, the differences were not related to the severity of sooty blotch. Peltaster fructicola and Leptodontidium elatius were grown on compounds that comprise the epicuticular wax of the fruit to determine if one or more of these were needed for growth. The fungi did not grow on any of the five major components of the epicuticular wax unless dilute apple juice was included. Scanning electron microscopy studies showed that mycelia of P. fructicola grew on the surface of the wax and did not appear to degrade it. Our studies support the hypothesis that P. fructicola and L. elatius fungi are epiphytes and obtain their nutrients not from components of the cuticle, but more likely from fruit leachates.}, number={7}, journal={PLANT DISEASE}, author={Belding, RD and Sutton, TB and Blankenship, SM and Young, E}, year={2000}, month={Jul}, pages={767–772} } @article{johnson_sutton_2000, title={Response of two fungi in the apple sooty blotch complex to temperature and relative humidity}, volume={90}, ISSN={["0031-949X"]}, DOI={10.1094/PHYTO.2000.90.4.362}, abstractNote={ Peltaster fructicola and Leptodontium elatius, two of the causal fungi of apple sooty blotch, responded differently to temperature and relative humidity in vitro. Conidia of L. elatius germinated from 12 to 32°C at relative humidities ≥97%, whereas conidia of P. fructicola germinated from 12 to 24°C at relative humidities ≥95%. Germination of conidia of L. elatius was optimum at 32°C and 99% relative humidity compared with 24°C and 97 or 99% relative humidity for P. fructicola. When L. elatius and P. fructicola were grown in Parafilm culture, sporulation was greatest at relative humidities of 97 to 99%. In agar culture, mycelia of L. elatius expanded radially from 12 to 32°C, and that of P. fructicola at 12 to 28°C. Mycelia of P. fructicola did not survive exposure for 7 days or more to temperatures ≥32°C. Mycelial growth was inhibited at relative humidities <95% for both fungi and no growth occurred at 88% relative humidity. Conidia of P. fructicola were more sensitive to air drying than were those of L. elatius. Conidial viability of P. fructicola was reduced significantly after 8 h of air drying and nearly completely inhibited after 12 h. Conidia of L. elatius required 24 h of air drying before a significant reduction in conidial viability was observed. These results support the hypothesis that environmental factors influence the temporal and geographical distributions of the fungi associated with the apple sooty blotch disease. }, number={4}, journal={PHYTOPATHOLOGY}, author={Johnson, EM and Sutton, TB}, year={2000}, month={Apr}, pages={362–367} } @article{marasinghe_hongsanan_zeng_jones_boonmee_hyde_2022, title={Taxonomy and ecology of epifoliar fungi}, volume={13}, ISSN={["2077-7000"]}, DOI={10.1094/PDIS.2000.84.7.714}, abstractNote={HomePlant DiseaseVol. 84, No. 7Sooty Blotch and Flyspeck of Apple: Etiology, Biology, and Control PreviousNext OPENOpen Access licenseSooty Blotch and Flyspeck of Apple: Etiology, Biology, and ControlSharon M.

No resistance to benomyl was detected in isolates collected during February 1994 from farms with no history of benomyl use that were located ≈50 km from the nearest banana plantations. Only 1% of isolates was resistant to benomyl in a sample taken during November 1994. In three additional banana farms where benomyl had not been used for 3 to 5 years before sampling, ben-omyl resistance persisted at a high frequency. Benomyl-resistant and -sensitive isolates were distributed equally throughout the range of isolate sensitivity to propiconazole, indicating no relationship between resistance to benomyl and lower sensitivity to propiconazole but double resistance to these two compounds. Five benomyl-resistant and five benomyl-sensitive isolates of M. fijiensis were inoculated to banana plants under greenhouse conditions. Benomyl-resistant isolates were more aggressive than benomyl-sensitive isolates, as determined by measures of disease severity, incubation time, and number of lesions at 40 days after inoculation. }, number={8}, journal={Plant Disease}, author={Romero, R.

Ascospores were the primary source of inoculum; only a few conidia were trapped during the study. Ascospores were trapped first during late April or early May. The spore discharge pattern was associated closely with seasonal rainfall distribution; in both years, the number of ascospores trapped increased rapidly through May, peaked during early June, declined rapidly through July, and were negligible during the rest of the year. Most ascospores were trapped during a 6- to 8-week period. Three principal discharge patterns were observed. One pattern, associated with rainfall, was characterized by the release of large numbers of ascospores within 1 h of the beginning of rainfall. Ascospore release often continued for several hours after the rainfall ended. A second discharge pattern was associated with dew. Large numbers of spores were trapped during periods when dew was heaviest (0200 to 0700 h). A third pattern consisted of a combination of the first two patterns (i.e., discharge during evening rain followed by a second discharge associated with dew). No relationship was found between different combinations of rainfall data and either the first or peak ascospore catch. Similarly, there was no consistent relationship between weekly percentages of leaves at different stages of decomposition and ascospore catch that could be used to predict the period of peak ascospore discharge. Weekly total number of leaves on the orchard floor was a better predictor of total ascospore catch. Two sprays of a copper fungicide reduced greasy spot incidence, severity, and defoliation compared to an unsprayed control. Oil, sprayed twice as a standard grower treatment, did not reduce disease incidence or severity compared to the unsprayed control. }, number={9}, journal={PLANT DISEASE}, author={Hidalgo, H and Sutton, TB and Arauz, F}, year={1997}, month={Sep}, pages={1015–1022} } @article{johnson_sutton_hodges_1997, title={Etiology of apple sooty blotch disease in North Carolina}, volume={87}, ISSN={["0031-949X"]}, DOI={10.1094/PHYTO.1997.87.1.88}, abstractNote={ Sooty blotch disease of apples (Malus × domestica), previously attributed to the fungus Gloeodes pomigena, was shown to be a disease complex caused by fungi previously considered mycelial types of G. pomigena.

A fungus similar to P. fructicola, but with smaller pycnothyria and conidia, was associated with the punctate mycelial type. The diffuse fuliginous mycelial type was caused by Leptodontium elatius. Fungi that fit the classical morphological description of G. pomigena were not observed. Pycnothyria of P. fructicola developed on overwintered colonies on blackberries, and conidia were a source for primary infection during the entire growing season. Secondary spread was through conidia produced in colonies on fruit. L. elatius was observed infrequently producing conidia on fruit during periods of extended high moisture. Histological examination did not reveal penetration of the cuticle of apple fruit for any of the fungi of the apple sooty blotch complex. }, number={1}, journal={PHYTOPATHOLOGY}, author={Johnson, EM and Sutton, TB and Hodges, CS}, year={1997}, month={Jan}, pages={88–95} } @article{romero_sutton_1997, title={Reaction of four Musa genotypes at three temperatures to isolates of Mycosphaerella fijiensis from different geographical regions}, volume={81}, ISSN={["1943-7692"]}, DOI={10.1094/PDIS.1997.81.10.1139}, abstractNote={ Two tetraploid banana hybrids, FHIA1 and FHIA2, with resistance to black Sigatoka, and two highly susceptible, naturally occurring triploids, Grand Naine and False Horn, were evaluated at three temperatures for their resistance to isolates of Mycosphaerella fijiensis from five geographical regions. The youngest open leaf of young plants was inoculated, and plants were incubated at 22, 26, and 30°C in growth chambers. Duration of the incubation period and disease severity were used to evaluate the reactions of the genotypes. The incubation period was the shortest at 26°C. Disease severity was greatest at 26°C on Grand Naine and False Horn, but there was no clear temperature effect for the FHIA genotypes. The incubation period was longer on both FHIA genotypes than on Grand Naine and False Horn. With few exceptions, isolates with the shortest incubation periods caused greater disease severity than those with longer incubation periods. The level of resistance between the two FHIA genotypes was similar, and both expressed high resistance across temperatures and isolates of M. fijiensis, indicating that no physiological races of the pathogen were detected. There were differences in durations of the incubation periods and disease severities associated with the geographical origin of the isolates.

Locations at San Pablo and Coopecariari had been sprayed with propiconazole for the past 7 years to control black Sigatoka. One hundred monoascosporic isolates from a third location, San Carlos, with no history of fungicide use, also were tested for sensitivity to propiconazole. Fifty percent effective concentration (EC50) values were calculated for individual isolates by regressing the relative inhibition of colony growth against the natural logarithm of the fungicide concentration. In the February sample, the mean EC50 values for San Pablo and Coopecariari populations were 0.06 and 0.05 μg a.i. ml-1, respectively, which were not statistically different (P = 0.05). The mean EC50 value of the population at San Carlos was 0.008 μg a.i. ml-1, which was significantly lower (P = 0.001) than the mean EC50 values obtained at San Pablo and Coopecariari. Frequency distributions of EC50 values of isolates from the three populations collected in February showed that 80% of isolates from San Pablo and Coopecariari had EC50 values greater than the highest EC50 value from San Carlos, indicating a significant shift in reduced sensitivity to propiconazole. Isolates collected in November 1994, after eight treatments of propiconazole at San Pablo and Coopecariari, showed a significant increase in mean EC50 values compared with the means observed in February. The high proportion of isolates with reduced sensitivity to propiconazole may account for the unsatisfactory control of black Sigatoka between 1992 and 1993 in the two banana plantations at San Pablo and Coopecariari. }, number={1}, journal={PHYTOPATHOLOGY}, author={Romero, RA and Sutton, TB}, year={1997}, month={Jan}, pages={96–100} } @misc{sutton_1996, title={Changing options for the control of deciduous fruit tree diseases}, volume={34}, ISSN={["0066-4286"]}, DOI={10.1146/annurev.phyto.34.1.527}, abstractNote={ ▪ Abstract  The evolution of disease management programs for deciduous fruit trees in the United States over the past 50 years has been influenced by factors that include public concern over pesticide residues on fruit and in the environment, the development of resistance of many important tree pathogens to fungicides and bactericides, the loss of fungicide registrations and restrictions on their use due to concern for human health and the environment and/or marketing decisions by the manufacturers, and changes in cultural practices and marketing objectives. These factors have led to wider use of forecasting models and cultural controls, the development of resistance management strategies, and the introduction of new equipment and methods for pesticide application. These same factors will most likely continue to drive the fruit industry to adopt disease management programs that rely less on pesticides in the future. }, journal={ANNUAL REVIEW OF PHYTOPATHOLOGY}, author={Sutton, TB}, year={1996}, pages={527–547} } @article{sutton_arauz_1991, title={INFLUENCE OF TEMPERATURE AND MOISTURE ON GERMINATION OF ASCOSPORES AND CONIDIA OF BOTRYOSPHAERIA-DOTHIDEA}, volume={75}, ISSN={["0191-2917"]}, DOI={10.1094/PD-75-1146}, abstractNote={Predicted optimum temperatures for germination of conidia of isolates 1, 2, and 3 of Botryosphaeria dothidea in free water were 26.7, 27.8, and 29.5 C.

B. 1990. Dispersal of conidia of Zygophiala jamaicensis in apple orchards. Plant Dis. 74: 643-646. Conidia of Zygophiala jamaicensis, the causal agent of flyspeck, were trapped in apple (Malus domestica) orchards or near reservoir inoculum sources from late May or early June through harvest (mid-September). Hourly spore concentrations were positively correlated with temperature and windspeed and negatively correlated with relative humidity and leaf wetness. Conidia concentration in the air was characterized by a distinct diurnal periodicity; most conidia were trapped between 0700 and 1300 hours. Fruit infections were usually observed about 1 mo after the first conidia were trapped. Management practices for flyspeck in apple orchards need to account for the presence and abundance of reservoir hosts, environmental conditions, orchard management strategies, and fungicide choice and timing. Flyspeck (caused by Zygophiala jamaicensis Mason; teleomorph, Schizothyrium pomi [Mont. & Fr.] Arx), is one of the most important diseases of apples (Malus domestica Borkh.) in the southeastern United States. Z. jamaicensis overwinters on apple twigs and on numerous reservoir hosts (2,9). Ascospores mature in late spring and initiate primary infections on apples and reservoir hosts. Conidia, produced from primary infections, initiate secondary cycles throughout the growing season. Numerous reservoir hosts are sources of inoculum. Rubus spp. are the most abundant reservoir hosts in North Carolina, however, at least 37 additional hosts have been identified (9). Control of flyspeck is based on the application of protectant fungicides applied at 10- to 14-day intervals. Not all fungicides registered for flyspeck control are equally effective against Z. jamaicensis. For instance, the ethylenebis[dithiocarbamate] (EBDC) fungicides are much more effective than captan (1); however, captan is often preferred because it provides better fruit finish early in the season and is more active against white rot (caused by Botryosphaeria dothidea [Moug. ex Fr.] Ces. & De Not.) and black rot (caused by Botryosphaeria obtusa [Schwein.] Shoemaker).
