Interpretive Summary:

Technical Abstract: Four experiments were conducted to determine the efficacy of broadcast 1,3-dichloropropene (65%) and chloropicrin (35%) mixed with pebulate and napropamide relative to in-bed applications of 1,3-dichloropropene (65%) and chloropicrin (35%) as an alternative to methyl bromide for soil fumigation in fresh market tomato production on flatwoods soils in west central Florida. 1,3-dichloropropene (65%) and chloropicrin (35%) applied in-bed was more efficacious for control of nutsedge than were broadcast treatments, unless chloropicrin was added to the bed. There was a high degree of variability within treatments and between years relative to control of Southern blight, although in-bed applications provided better control than did broadcast. The in-bed application provided control of this disease that was equivalent to methyl bromide. Fusarium wilt was controlled when additional chloropicrin was added to broadcast treatments, or when the in-bed application was used. Sting nematode was controlled by broadcast applications of 1,3-dichloropropene (65%) and chloropicrin (35%) in all but one year, but stunt nematode control with broadcast was no better than the untreated control. In-bed applications of 1,3-dichloropropene (65%) and chloropicrin (35%) resulted in tomato yields that were equivalent to methyl bromide, but broadcast applications resulted in yields that were lower than methyl bromide.
