Abstract

Management of paddy insect-pests by organic approaches was undertaken at Agricultural Research Station (ARS) farm, Gangavathi during Kharif 2011. Among the various organic treatments screened against insect pests and their safety to natural enemies NE's revealed that commercial neem @ 3ml/l recorded lower plant hopper population BPH (8.45/hill), WBPH (5.13/hill) and leaf folder damage (9.83%) at 3 DAS. This was followed by 'Agniasthra' 50 ml/l. Buprofezin 25% SC @ 1.0 ml/l which was recorded lower population of mirid bugs and spiders/ hill 7 days after spray followed by GCKE @ 10.0 ml and both are differed significantly from Sweet flag rhizome powder @ 20.0 g/l which was recorded higher population of mirid bugs and spiders per hill followed by Jeevamrutha @ 50.0 ml/l. The buprofezin 25% SC @ 1.0 ml/l significantly differ from other organic treatments which recorded higher yield of 72.88 q/ ha followed by commercial neem @ 3.0 ml/l (70.22 q/ha).
