Summary
During the course of studies on the ecology ofFusarium udum Butler, the incitant of wilt disease of pigeon-pea (Cajanus cajan (L.) Millsp.),Aspergillus nidulans was found to tolerate higher temperatures of summer, and other species includingF. udum were suppressed in field soil. The population ofA. nidulans increased in the soil incubated at 40±2°C at pH6 and 7 while the population ofF. udum was highly suppressed. The wilt disease of pigeon-pea was significantly suppressed at 38±2°C in the soil having a mixture of the inocula ofF. udum andA. nidulans whereas at lower temperature (25±2°C) no significant impact ofA. nidulans on the disease was found. On the basis of this study an integrated use of higher temperature, alkaline pH andA. nidulans has been suggested for biological control of wilt disease of pigeon-pea.
