Abstract:Incidence of several fungi, primarily Diaporthe phaseolorum var. sojae, was reduced in soybean plants inoculated at various growth stages with C. kikuchii. Both pods and seeds were implicated as sites of interaction but pods were the most likely site. Reductions in percentage pod infection and pod colonization by D. phaseolorum var. sojae suggest that establishment of infection and growth with pods were both inhibited. Variability in frequency and magnitude of reductions in seed infection by Diaporthe was caused primarily by the effect of weather on establishment of C. kikuchii. Increased seed germination from inoculation treatments was an indirect result of the reduction in seed infection by D. phaseolorum var. sojae. In investigations involving C. kikuchii-inoculated plants the effect(s) on other fungi and the consequences should be considered. ADDITIONAL ABSTRACT Inoculation of four lines in full bloom with C. kikuchii reduced seed infection by Diaporthe spp. and improved seed germination in Amsoy 71 and Wayne, varieties susceptible to both pathogens. PI80837, a variety which is less susceptible to C. kikuchii than the other three lines, consistently had the least C. kikuchii seed infection.
