Management of Mango malformation

Abstract

The mango (Mangifera indica L.) is considered as the king of fruits in India and is an essential fruit crop there. The most important biotic and abiotic issue is mango malformation, which can reduce yields by up to 60% and restrict mango farming in tropical and subtropical regions of the world. Vegetative and floral symptoms of mango malformation are expressed on the plant, and the floral symptom is far more virulent and results in the loss of the entire crop than the vegetative symptom produces. In this work the effectiveness of different chemicals was assessed for the control of these diseases in a mango orchard. There was a difference among modules for the malformation, the mixture of copper oxychloride 0.3% at the time of vegetative flush, subsequent spray carbendazim 0.1% at 20 days after first spray + spray propargite 0.18% at 20 days after second spray + spraying 200 ppm NAA in second week of December followed by spraying of 500 ppm ethrel at bud inception stage for the management of malformation in their mango orchards (cv. Kesar) as it very effective with 9.25 per cent infected diseased shoots.
