Abstract

Studies conducted for two years (2002-04) on evaluation of different sprayers revealed significant reduction in the larval population with high volume and low volume spray application as compared to ultra low volume spray, thus indicating their effectiveness. However, it was found that ultra low volume sprayer, mist blower and Aspee back pack high volume sprayer did not influence the grain yield. Among the different formulations tested, indoxacarb 14.5 SC @ 25 g a.i./ha was highly effective as compared to chlorpyriphos 20 EC@ 250 g a.i./ha irrespective of spray equipment and gave maximum protection to pods which resulted in increased grain yield
