Management of Sclerotinia blight of peanut requires an integrated approach that includes rotation with non-hosts, resistant cultivars, cultural practices, and fungicides. Greenhouse experiments compared fluazinam and boscalid and investigated pre- and post-inoculation applications of fungicide or no fungicide to control infections by S. minor. Significant reductions in successful infections in the greenhouse occurred when fungicide was applied prior to, or up to 2 d after, inoculation, but not when applied 4 d after inoculation. Field experiments were conducted from 2004 to 2006 to investigate the comparative efficacy of the fungicides fluazinam and boscalid using alternating sequences of those fungicides or no fungicide for each of three sprays per season. In the field, applications of fungicide that preceded the largest incremental increase in disease incidence provided the best control of disease or increased yield. In both the field and greenhouse studies boscalid performed marginally better than fluazinam. Disease advisories or intensive scouting should be used to determine when epidemics initiate so that a fungicide can be applied prior to infection.}, number={3-5}, journal={CROP PROTECTION}, author={Smith, D.

 @article{smith_hollowell_isleib_shew_2007, title={A site-specific, weather-based disease regression model for Sclerotinia blight of peanut}, volume={91}, ISSN={["1943-7692"]}, DOI={10.1094/PDIS-91-11-1436}, abstractNote={In North Carolina, losses due to Sclerotinia blight of peanut, caused by the fungus Sclerotinia minor, are an estimated 1 to 4 million dollars annually. In general, peanut (Arachis hypogaea) is very susceptible to Sclerotinia blight, but some partially resistant virginia-type cultivars are available. Up to three fungicide applications per season are necessary to maintain a healthy crop in years highly favorable for disease development. Improved prediction of epidemic initiation and identification of periods when fungicides are not required would increase fungicide efficiency and reduce production costs on resistant and susceptible cultivars. A Sclerotinia blight disease model was developed using regression strategies in an effort to describe the relationships between modeled environmental variables and disease increase. Changes in incremental disease incidence (% of newly infected plants of the total plant population per plot) for the 2002–2005 growing seasons were statistically transformed and described using 5-day moving averages of modeled site-specific weather variables (localized, mathematical estimations of weather data derived at a remote location) obtained from SkyBit (ZedX, Inc.). Variables in the regression to describe the Sclerotinia blight disease index included: mean relative humidity (linear and quadratic), mean soil temperature (quadratic), maximum air temperature (linear and quadratic), maximum relative humidity (linear and quadratic), minimum air temperature (linear and quadratic), minimum relative humidity (linear and quadratic), and minimum soil temperature (linear and quadratic). The model explained approximately 50% of the variability in Sclerotinia blight index over 4 years of field research in eight environments. The relationships between weather variables and Sclerotinia blight index were independent of host partial resistance. Linear regression models were used to describe progress of Sclerotinia blight on cultivars and breeding lines with varying levels of partial resistance. Resistance affected the rate of disease progress, but not disease onset. The results of this study will be used to develop site- and cultivar-specific spray advisories for Sclerotinia blight.}, number={11}, journal={PLANT DISEASE}, author={Smith, D. L. and Hollowell, J.

The effects of soil temperature and soil matric potential (ψ M on germination and growth of S. minor have not been well characterized, and little is known about relative physiological resistance in different parts of the peanut plant. Laboratory tests examined the ability of the fungus to germinate, grow, and infect detached peanut leaflets at soil temperatures ranging from 18 to 30°C at ψ M of -100, -10, and -7.2 kPa. In addition, detached pegs, leaves, main stems, and lateral branches from three peanut lines varying in field resistance were examined for resistance to infection by S. minor. Sclerotial germination was greatest at 30°C and ψ M of -7.2 kPa. Final mycelial diameters decreased with decreasing ψ M , whereas soil matric potential did not affect lesion development. Mycelial growth and leaflet lesion expansion were maximal at 18 or 22°C. Soil ψ M did not affect leaflet infection and lesion expansion. Lesions were not observed on leaves incubated at temperatures of 29°C or above, but developed when temperatures were reduced to 18 or 22°C 2 days after inoculation. Pegs and leaflets were equally susceptible to infection and were more susceptible than either main stems or lateral branches. Results of this work, particularly the effects of temperature on S. minor, and knowledge of peanut part susceptibility has application in improving Sclerotinia blight prediction models for recommending protective fungicide applications.}, number={11}, journal={PLANT DISEASE}, author={Smith, D.
