Abstract
Mycelial growth of Lasiodiplodia theobromae was significantly inhibited by Carbendazim and Thiophanate-methyl when used @ 1 ppm a.i. or more. Alliete was effective at relatively high concentrations i.e., @ 1000 and 10000 ppm a.i., whereas, Copxykil, Cuprocaffaro and Thiovit failed to inhibit the mycelial growth of L. theobromae. In field experiment, Carbendazim was found to be more effective than Thiophanate-methyl and Alliete in reducing the fungal infection in mango plants, suppressing the gum exudation, dieback and wilting resulting in significant enhancement in vegetative growth of plants.
