Abstract
Vegetable production in plasticulture system is common in Georgia and Southeastern United States. Root-knot nematodes (RKN) are one of the serious pests of vegetable crops and can drastically reduce yield if not effectively managed. This study investigated the best chemical options for RKN management in a double-cropped vegetable plasticulture system. We found Pic60, a mixture of chloropicrin (59.6%) and 1,3-dichloropropene (39%), to be a good choice for effective RKN control and yield increase in pepper grown on plastic beds in the spring season. Also, non-fumigant nematicides (fluensulfone, fluazaindolizine, fluopyram, oxamyl, Burkholderia spp. strain A396) were applied in the same plastic beds in the summer season and reduced RKN damage in squash. In another study seeking to optimize the drip application of non-fumigant nematicides for RKN control, we observed that the surface and sub-surface application of fluensulfone, fluazaindolizine, and fluopyram had comparable effects to the surface application of the nematicides.
