Wells soybeans (Glycine max) infected with Septoria glycines yielded less than uninfected benomyl-sprayed soybeans. Seed weight was reduced by S. glycines infection. The rate of leaf loss over time for S. glycines-infected plants was greater than for benomyl-sprayed plants during the pod-fill stage of development. The rate of dry matter accumulation in pods of S. glycines-infected plants was less than in benomyl-sprayed plants. There was no difference in pod numbers between S. glycines-infected and benomyl-sprayed plants.
