Efficacy of newer insecticides against Aceria jasmini in Jasminumauriculatum

摘要

The field trial was conducted on different newer insecticides with neem oil against Aceria jasmini in Jasminum auriculatum two sprays were given at fifteen days intervals. Amongst the treatments in first spray, the propargite @ 0.5 ml/1 effectively reduced the mites population preceded by abamectin @ 0.3 ml/I and neeem oil @ 30 ml/I. In second spray abamectin @ 0.3 ml/1 followed by neeem oil @ 30 ml/I and propargite @ 0.5 ml/I effectively reduced the mite population. Above 95 per cent of the mortality was recorded in propargite @ 0.5 ml/1 and abamectin @ 0.3 ml/I at fifteenth days after spray.
