Abstract
Four consecutive field trials were conducted in a four-season study to determine the long-term efficacy of supplementary in-bed applications of chloropicrin (Pic) in addition to 1,3-dichloropropene plus Pic (1,3-D+Pic) on soilborne pest control and tomato ( Lycopersicon esculentum Mill.) yield. Treatments compared combinations of in-bed and broadcast 1,3-D and Pic with an untreated control and were repeated over several seasons. Results indicated that in-bed applications of C-35 and MBr+Pic consistently had the highest control of soilborne fungus ( Fusarium oxysporum f.sp. lycopersici race 3), weeds ( Cyperus spp.), and nematodes ( Meloidogyne spp., Belonolaimus spp., and Tylenchorhynchus spp.) and tomato fruit weights, followed by the C-35+Pic, and 1,3-D+Pic, which had excellent performance in three of the four tomato seasons.
