The incidence of most fungi in soybean (Glycine max) leaves, pods, and seeds was reduced by benomyl treatment. Significant reductions occurred for Diaporthe phaseolorum var. sojae, Colletotrichum dematium var. truncata, Glomerella glycines, and Cercospora kikuchii. Several fungi, including Alternaria alternata and Fusarium spp., increased in frequency. Significant reductions and increases in the incidence of fungi in leaves, pods, and seeds were greater in lower than in intermediate and upper positions on benomyl-treated plants.
