Pest control with drip‐applied dimethyl disulfide and chloropicrin in plastic‐mulched tomato ( Solanum lycopersicum L.)

Dimethyl disulfide (DMDS) is used as a preplant soil fumigant for weed and soilborne pathogen control in plasticulture vegetable crops. The objective of this research was to determine the control efficacy of emulsifiable concentrate (EC) formulation of DMDS or DMDS + chloropicrin (Pic) on weed and Fusarium wilt in tomato (Solanum lycopersicum L.) plasticulture.The effective DMDS rates required to provide 50% (ER50 ) control of purple nutsedge...
