Bio-efficacy of bullock drawn solar powered high clearance sprayer

Abstract

The study was conducted to evaluate the bullock drawn solar powered high clearance sprayer for cotton (Bt cotton hybrid MRC 7351) and red gram (Maruthi ICP 8863) at the farmer’s field, Raichur. The insecticide used was dinotefuran (Osheen) solution with a recommended dose of 200 g 1000 l-1. The chemical used for spraying the red gram crop was chlorantriniprole with a recommended dose of 200 g 1000 l-1. The insects were reduced from pre counting as the number of days increased after the spraying. The populations of aphids were 12, after 10 days reduced to 3.7 numbers. The percentage of pod damage significantly reduced in red gram crop. The results of present study conclude that bullock drawn solar powered high clearance sprayer is found to be superior when compared to conventional gun spraying.
