Interpretive Summary:

Technical Abstract: The methyl bromide phase-out has been delayed to the year 2005. Alternatives for methyl bromide as a broad-spectrum soil fumigant to control soilborne diseases, nematodes, weeds, and other pests are needed in crop production systems. Combinations of 1,3-dichloropropene and 1,2- dichloropropane (Telone II) + metam sodium, metam sodium + chloropicrin and dmetam sodium + Telone C-17, Telone II, Telone C-17, Telone C-35, and chloropicrin were field tested to control soilborne diseases, nematodes, and weeds in tobacco seed beds, pepper and tomato seedlings. The combination of metam sodium + chloropicrin, Telone C-17, and Telone C-35 were most effective for reducing population densities of fungi in the soil. Most chemical treatments except chloropicrin eliminated Pythium spp. from toothpick cultures placed in the soil. Nematode population densities were low and there were generally no differences among treatments. Weed population densities were low; however, all chemical treatments, except chloropicrin alone were effective in suppression of corn spurrey, cutleaf evening primrose, yellow nutsedge, henbit, and annual sedge. Some of these treatments, with refinement, may prove as alternatives for methyl bromide.
