Abstract
Effects of a mixture of the postemergence herbicides acifluorfen and bentazon, and simulated defoliation expected from green cloverworm on population densities of Heterodera glycines were determined in field plots in Iowa. The herbicide mixture and defoliation each suppressed soybean growth. Population densities of H. glycines were generally lower in herbicide-treated than untreated plots. Population densities of the nematode were unaffected by defoliation in 1988 and 1990-91, but were increased by the treatment in 1989. Key words: acifluorfen, bentazon, defoliation, Glycine max, green cloverworm, herbicide, Heterodera glycines, nematode, Plathypena scabra, postemergence herbicides, soybean, soybean cyst nematode.
