In vitro management of Pestalotiopsis mangiferae causing grey leaf blight of mango by fungicides

Abstract

Mango (Mangifera indica L.) is one of the most important commercially grown fruit crops in India and is also known as the national fruit of the country. In mango, out of the all diseases, grey leaf blight disease has a great economic importance. An in vitro experiment was performed by screening different fungicides against Pestalotiopsis mangiferae, the causal agent of the disease by poisoned food technique. Amid fungicides tested, carbendazim 12% + mancozeb 63% @ 0.15, 0.2 and 0.25%, cymoxanil 8% + mancozeb 64% @ 0.15, 0.2 and 0.25% and copper oxychloride @ 0.2% were found best in inhibiting the pathogen growth by 100 percent and recorded highest inhibition (%) over control in comparison with control.
