Abstract:
A field experiment was conducted to study the efficacy of newer molecules against red spider mite, Tetranychus urticae Koch during rabi 2020-21 in tomato under protected cultivation at Hi-tech horticulture unit, UAS, Dharwad. The efficacy of nine newer combination products found to be significantly superior when compared with untreated control. Among the treatments, spirotetratmat 11.01 SC + imidacloprid 11.01 SC @ 1.0 ml/l found to be the best treatment in reducing the mite population (3.39 mites/3 leaflets) by recording the highest percent reduction of 78.35. This was followed by pyriproxyfen 5 EC + fenpropathrin 15 EC (72.19%), spinosad 45 SC + buprofezin 25 SC (65.81%) and buprofezin 25 SC (59.68%) The spinosad 45 SC and indoxacarb 14.5 SC + acetamiprid 7.7 SC recorded as least effective treatment with 11.52 and 14.20 percent reduction (13.91 and 13.50 mites/3 leaflets) over the untreated control.
