Abstract:

Based on two Colletotrichum gloeosporioides isolates came from HaiNan province, 13 fungicides were screened in laboratory by hypha growth rate method. Propiconazol 25 % EC, prochloraz 25 % EC and carbendazim 50 % WP were found to have the lowest EC50 value and good inhibition of Colletotrichum gloeosporioides isolates, whereas fenaminosulf 55 % WP and mancozeb 50 % WP had the highest EC50 value but poor inhibition, propiconazol, prochloraz and carbendazim were suggested to be used for field control of Cassava Anthracnose.
