Abstract : The experiment was conducted on Alphonso mango cultivar by using Azoxystrobin 23% SC fungicides. In this study, the efficacy of Azoxystrobin 23% SC, one of the strobilurin class fungicides, was evaluated both in vitro and in vivo conditions. Under in-vitro tests, Azoxystrobin completely inhibited mycelial growth of C. gloeosporioides. In field experiment. Azoxystrobin at 0.06, 0.10 and 0.14 ml/l significantly suppressed the development of anthracnose and powdery mildew on blossom. Similarly phyto-toxicity was also tested at 0.1, 0.2 and 0.4 ml/l. Mango trees treated with Azoxystrobin produced more fruits compared to control and does not shown any phyto-toxicity. Hence this systemic fungicide Azoxystrobin was useful in managing this destructive disease of mango in field.
