Small-plot research and large-field validations were conducted to determine the effect of 1,3-dichloropropene (1,3-D) + chloropicrin (Pic) application methods in combination with the herbicides pebulate and napropamide on pest control in fresh market tomato (Lycopersicon esculentum Mill.). In both the small-plot trials and the large-validation fields, various treatments compared the efficacy of soil fumigants and herbicides based on methyl bromide, in-bed and broadcast applications of 1,3-D + Pic, pebulate, and napropamide. The results consistently indicated that either in-bed or broadcast applications of 1,3-D + Pic in combination with pebulate and napropamide are equally effective against the weed Cyperus spp., the nematodes Tylenchorhynchus spp., Belonolaimus longicaudatus, and Meloidogyne spp., and the soilborne disease Fusarium oxysporum f.sp. lycopersici in fresh market tomato. Therefore, broadcast 1,3-D + Pic application can reduce personnel exposure and poisoning risks, without losing pest control efficacy.
