Evaluation of some systemic and nonsystemic fungicides against Colletotrichum gloeosporioides and Diplodia natalensis causing post harvest fruit rot of mango.

Five fungicides, 2 systemic (carbendazim as Bavistin and thiophanate-methyl as Topsin M) and 3 nonsystemic (captan as Captaf, ziram as Cuman L and chlorothalonil as Kavach) were tested against Colletotrichum gloeosporioides [Glomerella cingulata] and Diplodia natalensis [Botryodiplodia theobromae] causing postharvest fruit rot of mango. The fungicides were applied at 2000 ppm as a preharvest control measure. In vitro studies showed complete inhibition of G. cingulata at 400 ppm with carbendazim followed by captan (450 ppm), thiophanate-methyl (450 ppm), ziram (550 ppm) and chlorothalonil (550 ppm). Linear growth of B. theobromae was also completely inhibited at 400 ppm carbendazim followed by captan (450 ppm), thiophanate-methyl (450 ppm), ziram (600 ppm) and chlorothalonil (650 ppm). In vivo, artificial inoculation of fungicide treated mango fruits, however, indicated that carbendazim and thiophanate-methyl gave the best control of both G. cingulata and B. theobromae followed by ziram and capta
