In vitro inhibitory effect of botanicals and fungicides on mycelial growth of Peziotrichum corticolum (Massee) Subramanian causing Black banded disease of mango

Abstract

India is the largest producer of mango (Mangifera indica L.) in the world accounting for 52-63 per cent of total production. One of the constraints in mango production is black banded disease caused Peziotrichum corticolum (Massee) Subramanian which is during previous four to five years has been on the rise under south Gujarat ecosystem. The black velvety growth of fungus can be found on the midribs and veins of leaves, twigs and branches. Therefore, an attempt was made with different botanicals and fungicides in managing the causal agent of black banded of mango. This investigation suggests leaf extract of Azadirachta indica andmancozeb, difenoconazole, propiconazole, carbendazim + mancozeb and hexaconazole + zineb as the most effective fungicides in combating mycelial growth of the fungus under in vitro conditions.
