Efficacy of different acaricides against rice sheath mite, Steneotarsonemus spinki smiley on rice crop

MB Lakum, PD Ghoghari and SD Chaudhari

An experiment was conducted during kharif-2016 at Main Rice Research Centre, Navsari Agricultural University, Navsari to test the relative efficacy of some acaricides against rice sheath mite, Steneotarsonemus spinki Smiley. Among all the acaricides tested, chlorfenpyr 10 SC @ 1.00 ml/litre and buprofezin 25 EC @ 1.20 ml/litre were found to be most effective in controlling S. spinki. The next best effective treatments in the order of merit were diafenthiuron 50 WP @ 1.10 g/litre, propargite 57 EC @ 1.00 ml/litre and fenpyroximate 5 EC @ 0.50 ml/litre in terms of reduction of sheath mite population. As far as the yield is concerned, the highest grain yield was recorded in the treatment of chlorfenpyr 10 SC @ 1.00 ml/litre (5024 kg/ha) and it was at par with the treatment of buprofezin 25 EC @ 1.20 ml/litre (4922 kg/ha), diafenthiuron 50 WP @ 1.10 g/litre (4799 kg/ha), propargite 57 EC @ 1.00 ml/litre (4493 kg/ha), fenpyroximate 5 EC @ 0.50 ml/litre (4084 kg/ha), abamectin 1.9 EC @ 1.30 ml/litre (4003 kg/ha) and fenazaquin 10 EC @ 1.00 ml/litre (3839 kg/ha). The highest straw yield was recorded in the treatment of chlorfenpyr 10 SC @ 1.00 ml/litre (6515 kg/ha) and it was at par with buprofezin 25 EC @ 1.20 ml/litre (6454 kg/ha), diafenthiuron 50 WP @ 1.10 g/litre (6413 kg/ha), propargite 57 EC @ 1.00 ml/litre (6392 kg/ha) and fenpyroximate 5 EC @ 0.50 ml/litre (6086 kg/ha).
