In recent years, reduced tillage systems, and grass and pasture rotations have been investigated to help maintain or improve soil quality, increase crop yield, and decrease labor requirements for production. However, documentation of the effects of reduced tillage, fescue rotation systems as well as other management practices, including pesticides, on pest damage and soil arthropod activity in peanut production for the Mid-Atlantic US region is still limited. Therefore, this project was implemented to assess impacts of fescue-based rotation systems on pests and other soil organisms when compared with cash crop rotation systems over four locations in eastern North Carolina. In addition, the effects of tillage (strip vs. conventional) and soil chlorpyrifos application on pod damage and soil-dwelling organisms were also evaluated. Soil arthropod populations were assessed by deploying pitfall traps containing 50% ethanol in each of the sampled plots. Results from the present study provide evidence that location significantly impacts pest damage and soil arthropod diversity in peanut fields. Cropping history also influenced arthropod diversity, with higher diversity in fescue compared with cash crop fields. Corn rootworm damage to pods was higher at one of our locations (Rocky Mount) compared with all others. Cropping history (fescue vs. cash crop) did not have an effect on rootworm damage, but increased numbers of hymenopterans, acarina, heteropterans, and collembolans in fescue compared with cash crop fields. Interestingly, there was an overall tendency for higher number of soil arthropods in traps placed in chlorpyrifos-treated plots compared with nontreated controls.}, number={4}, journal={ENVIRONMENTAL ENTOMOLOGY}, author={Cardoza, Yasmin J. and Drake, Wendy L. and Jordan, David L. and Schroeder-Moreno, Michelle S. and Arellano, Consuelo and Brandenburg, Rick L.}, year={2015}, month={Aug}, pages={951–959} }

Research was conducted to determine interactions of planting date, tillage system, and cultivar with respect to disease reaction and pod yield of peanut. The cultivars Bailey, CHAMPS, Gregory, Perry, and Phillips were planted in early or late May in reduced or conventional tillage systems from 2008 through 2011 at one location in North Carolina. The interaction of year, tillage system, and cultivar was significant for plant condition rating (PCR), a visible estimate of disease, within 3 d before digging from late September through mid‐October. Pod yield was correlated with PCR in mid‐September (P = 0.0001, R2 = –0.22) and PCR just before digging (P ≤ 0.0001, R2 = –0.31). Disease was less prevalent for the cultivar Bailey and most prevalent for the cultivar Phillips, with disease for the other cultivars intermediate between Bailey and Phillips. Pod yield was influenced independently by cultivar, planting date, and tillage system although each of these factors was affected by year of the experiment. Pod yield was similar in strip tillage and conventional tillage in 3 of 4 yr with yield in strip tillage exceeding conventional tillage in 1 yr. Peanut planted in early May yielded more than peanut planted in late May in 2 of 4 yr. Results indicate that while some differences in disease reaction will occur when comparing cultivars, planting dates, and tillage systems, pod yield will be affected independently by these cultural practices.}, number={2}, journal={AGRONOMY JOURNAL}, author={Drake, W.

However, research comparing these systems in North Carolina is limited. Therefore, research was conducted at four locations in North Carolina to compare corn (Zea mays L.), cotton (Gossypium hirsutum L.), peanut (Arachis hypogaea L.), and soybean [Glycine max (L.) Merr.] yield when these crops were strip tilled following 4 yr of continuous tall fescue (Shedonorus phoenix Scop.) vs. 4 yr of either corn or cotton grown in no tillage or strip tillage. Cotton yield was higher following tall fescue compared with yield following agronomic crops. In contrast, yield of corn was lower following tall fescue compared with agronomic crops while peanut and soybean yields were not affected by previous cropping history. Additional treatments in peanut included conventional tillage following both cropping systems, and pod yield was lower when peanut was strip tilled into either tall fescue or residue from corn or cotton compared with conventional tillage systems. No major differences in soil bulk density at depths of 0 to 8 cm or 8 to 16 cm were noted when comparing tall fescue or agronomic crops either in strip tillage or nontilled zones. Populations of soil parasitic nematodes were often lower in peanut following tall fescue than when following agronomic crops. These experiments indicate that sod‐based systems may be an effective alternative to reduced tillage systems, especially for cotton. However, yield benefits were not observed for peanut or soybean and corn was negatively affected by tall fescue.}, number={6}, journal={Agronomy Journal}, publisher={Wiley}, author={Drake, W.

Experiments were conducted during 2007 and 2008 to determine if cultivars vary in response to interactions of the insecticide aldicarb (no aldicarb or aldicarb applied in the seed furrow at planting) and the herbicide paraquat (no paraquat or paraquat applied 24 to 28 d after peanut emergence, DAE). The cultivar VA 98R expressed more damage from tobacco thrips than the cultivars Gregory, Perry, or Phillips. Although vegetative growth parameters varied among cultivar, aldicarb, and paraquat treatments, pod yield and market grade characteristics were not affected by the interaction of experiment, cultivar, aldicarb, and paraquat or the interaction of cultivar, aldicarb, and paraquat. Damage from tobacco thrips in absence of aldicarb affected pod yield more than injury from paraquat. The combination of tobacco thrips damage in absence of aldicarb and injury from paraquat lowered pod yield compared with aldicarb‐treated peanut either with or without paraquat regardless of cultivar. These data suggest that recommendations on use of aldicarb for tobacco thrips control or paraquat for early season weed control should not vary based on cultivar selection when considering pod yield and market grade characteristics.}, number={6}, journal={AGRONOMY JOURNAL}, author={Drake, Wendy L. and Jordan, David L. and Lassiter, Bridget R. and Johnson, P.
