Mycoflora of soybean leaves, pods, and seeds in Mississippi

Abstract
Fifty-six fungal taxa, 10 of which were previously unreported from soybean, were isolated from soybean leaves, pods, or seeds periodically sampled during two growing seasons. Incidence of fungi varied annually owing in part to differences in rainfall. Some of the more frequently isolated fungi, in order of prevalence, were Alternaria alternata, Diaporthe phaseolorum var. sojae, and Phorna spp. (from leaves); D. phaseolorum var. sojae, A. alternata, and Fusarium spp. (from pods); and Fusarium spp., D. phaseolorum var. sojae, and A. alternata (from seeds). Frequency of occurrence of the more prevalent fungi usually increased in plant tissues throughout the sampling period while other fungi often decreased in frequency. Incidence of some fungi was related to the spatial distribution of plant organs from which they were isolated.
