Technical Abstract: Soil solarization, applied alone or in combination with 1,3-dichloropropene or municipal solid waste compost, was evaluated as an alternative to preplant fumigation with methyl bromide. In Palm Beach County, marketable yield of pepper was 15.3 and 16.4 tons/acre from solarized and methyl bromide treated areas, respectively, while suppression of nutsedge and the density of root-knot nematodes were similar under both treatments. Following a subsequent second crop of cucumber, reductions in marketable yield and increases in the severity of root galling and density of root-knot nematodes were observed in untreated or solarized areas, but not in an area treated with soil solarization plus 1,3-dichloropropene. In Suwannee County, suppression of yellow and purple nutsedge was similar in plots receiving soil solarization or methyl bromide while reductions in root galling and density of root-knot nematodes were greatest in plots treated with methyl bromide. Marketable yield of cucumber was greatest in methyl bromide-treated areas.
