Abstrakt: In Northern Bangladesh, generally mango trees are planted as agroforest that gives higher Net Present Value (NPV) than traditional agriculture. Mango anthracnose caused by Colletotrichum gloeosporioidesPenz. is seen as a very destructive and widely distributed disease, which results in poor market value. Five fungicides such as Cupravit, Bavistin, Dithane M-45, Thiovit and Redomil were tested against conidial germination of C. gloeosporioides.Dithane M-45 and Redomil were the most effective when the eonidia were immersed for 10~20 minutes at 500~1000 ppm concentrations. Antifungal activities of 13 plant extracts were tested against conidial germination of C. gloeosporioides.Conidial germination of C. gloeosporioideswas completely inhibited in Curcuma ionga(leaf and rhizome), Tagetes erecta(leal) and Zingiber officinales(rhizome) after 15 minutes of incubation respectively.
