Abstract
The efficacy of foliar application of benzpyrimoxan 10SC @ 50, 75, 100, 125 and 150 g a.i./ ha besides the insecticidal checks imidacloprid 17.8SL @ 25 g a.i./ha and buprofezin 25SC @ 187.5 g a.i./ha was evaluated against the brown planthopper (BPH) Nilaparvata lugens (Stal.) and the white backed planthopper (WBPH) Sogatella furcifera (Horvath) on rice during kharif 2017 and 2018 at the Punjab Agricultural University, Ludhiana. Experimental design consisted of random blocks in three replications. Two years data revealed that benzpyrimoxan 10SC @ 100 g a.i./ha is significantly superior against the N. lugens and S. furcifera complex. Benzpyrimoxan 10SC @ 100 g a.i./ha gave significantly higher yield (34.17 q/ ha) than its lower doses but was statistically at par with its higher doses. Non-significant differences in number of spiders/hill among treated plots and untreated check at 10- and 15-DAS indicated the safety of benzpyrimoxan.
