TAILIEUCHUNG - Maruka pod borer [Maruca vitrata (Geyer)] Management in Blackgram (Vigna mungo L.) in Krishna district of Andhra Pradesh, India

On farm trials in ten locations were conducted to evaluate efficacy of IPM strategies against maruka pod borer [Maruca vitrata (Geyer)] with emphasis on timely observation of the pest incidence, levels of infestation and alternation of different groups of insecticides properly so that even with repeated use of insecticides having different mode of action with an aim to see that the pest may not develop resistance against particular group of insecticides besides achieving proper management of the maruka pod borer and to create awareness among the farming community during rabi, 2014-15 to 2017-18 in the farmer‟s fields in Krishna District of Andhra Pradesh. By adoption of IPM practices in all the four years, the pod borer damage was reduced on an average by per cent compared to per cent in farmers practice. This has resulted in reduction in the average cost of cultivation by Rs. per hectare and the average net income was improved by Rs. 10417 per hectare compared to the farmers practice. The average yield levels in the demonstration ( qt/ha) improved by per cent compared to farmers practice ( qt/ha) and giving a clear message that adoption of IPM practices with emphasis observation of the pest intensity and using different insecticides helped in reducing the pest levels, damage and improving yield; helps in improving the decision making capacity and net income levels to the resource poor farmers. | Maruka pod borer [Maruca vitrata (Geyer)] Management in Blackgram (Vigna mungo L.) in Krishna district of Andhra Pradesh, India
