In vitro cross pathogenicity and management of Colletotrichum gloeosporioides causing anthracnose of mango

Cross pathogenicity studies on Colletotrichum gloeosporioides revealed that the isolates obtained from mango, citrus, guava had capability to infect the host of each other except the citrus leaves. Complete inhibition of linear growth of C. gloeosporioides by systemic fungicides viz. bavistin and topsin-M proved most effective at the concentration of 100 μg/ml. Among the non-systemic fungicides, kavach and dithane M-45 provided complete growth inhibition at 1000 μg/ml followed by captaf and bordeaux mixture.
