Interpretive Summary:

Technical Abstract: Methyl bromide is a broad-spectrum biocide and is an important management tool for controlling nematodes, soilborne diseases and other pests in a wide range of crops including vegetables. Methyl bromide production and importation will be reduced from 1991 levels 25% in 1999, 50% in 2001, 70% in 2003, and 100% in 2005. Therefore, alternative pest management strategies must be developed before year 2005. One, 3-dichloropropene (1,3-D), chloropicrin, metam sodium and combinations of metam sodium + 1,3-D, metam sodium + chloropicrin, and metam sodium + 1,3-D + chloropicrin were applied to determine the efficacy on soilborne fungi, nematodes, and weeds. Metam sodium + chloropicrin, 1,3-D + 17% and 35% chloropicrin were most effective in suppressing population densities of Rhizoctonia solani AG-4, Pythium spp., Fusarium spp., and Trichoderma spp. Nematode population densities were low and were not affected by soil treatments. Weed population densities were low; but all treatments except chloropicrin alone suppressed corn spurrey, cutleaf evening primrose, yellow nutsedge, henbit, and annual sedge. Metam sodium + chloropicrin and 1,3-D + chloropicrin + enide show promise as alternatives for methyl bromide.
