Cost, Benefit Ratio, Integrated Pest Management Module, Intercrop, Natural Enemies.
Abstract
In an attempt to develop an integrated pest management (IPM) strategy for cotton pests four modules comprising integrated pest control tactics, judicious use of pesticides, farmer's practice and untreated control were evaluated. The approach, consisting of limited use of pesticides coupled with biocontrol measures and other resistance management strategies, was found economically viable for sustaining cotton production in addition to conserving and augmenting natural enemies in the cotton ecosystem. IPM practice also resulted in a higher cost:benefit ratio (1:5.3 and 1:6.1) in comparison with the farmer's practice (1:2.5 and 1:1.6).
