In-vitro evaluation of fungicides against Cylindrocladium spp causing defoliation and die-back in Cashew

Among all the 10 fungicides/ fungicide combinations under study, complete inhibition of the mycelial growth occurred in mancozeb (0.00mm) and metalaxyl in combination with mancozeb. They were followed by zineb plus hexaconazole (12mm), Chlorothalonil (12.33mm), carbendazim (15.67mm), Zineb (17.33mm), Hexaconazole (17.67mm), thiophenate methyl (18.00mm), copper oxy-chloride (26.00mm) and copper hydroxide (27.00mm) respectively. Maximum growth (90.00 mm) was recorded in control.
