ABSTRACT

A field experiment was conducted to study on integrated pest management (IPM) in chilli crop with comparison to Non- IPM at Regadaguduru village, Velugodu mandal, Kurnool district, Andhra Pradesh. Repeated usage of the pesticides causes severe ecological consequences. Alternate approach consisting of ecofriendly components are safe and is most preferable in plant health management. In this view, an investigation was carried out on evaluation of different IPM modules against pest complex of chilli. In the year 2013-14, the numbers of IPM interventions were 16 as against 21 numbers of interventions in Non-IPM plot for cultivar Devanur Deluxe, whereas in case of Super-10 cultivar, it was 16 in IPM plots as against 21 in Non-IPM plots. The IPM plot planted with Devanur Deluxe recorded an average yield of 43.55 q/ha with a net profit of Rs. 1,63,598/- as against 42.25 q/ha of dry chilli with a net profit of Rs1,54,088/- in Non-IPM plot which is a net gain of Rs. 9,510/- in IPM plot. The production cost was Rs. 550/- less in IPM plots and the protection cost was Rs. 17,103/- less compared to Non-IPM plot. The IPM plot Planted with Super-10 recorded an average yield of 51.25 q/ha with a net profit of Rs. 1,68,868/- as against 47.35 q/ha of dry chilli with a net profit of Rs.1,48,882/- in Non-IPM plot which is a net gain of Rs. 19,986/- in IPM plot. The production cost for Super-10 was Rs.3,150/- less and protection cost was less Rs.13,723/-. In Devanur Deluxe, the cost benefit ratio was recorded as 1:2.39 in IPM field and 1:2.06 in Non- IPM field where as in Super-10, it was 1:2.29 in IPM field and 1:1.97 in Non- IPM field respectively.
