Bio-efficacy of different acaricides against broad mite, Polyphagotarsonemus latus (Banks) in Kharif sesame
Journal of Pharmacognosy and Phytochemistry(2019)
摘要
Investigation on the management of broad mite, Polyphagotarsonemus latus infesting sesame was carried out under field condition during the kharif- 2018 at Instructional Farm, Junagadh Agricultural University, Junagadh, India. For the management of mites, different acaricides viz., hexythiazox 5.45 EC @ 0.008%, ethion 50 EC @ 0.05%, ethion + cypermethrin 45 EC @ 0.045%, fenpyroximate 5 SC @ 0.005%, etoxazole 10 SC @ 0.01%, abamectin 1.9 EC @ 0.0019%, diafenthiuron 50 WP @ 0.05%, fenazaquin 10 EC @ 0.01% and propargite 57 EC @ 0.057% were evaluated against the pest. Based on pooled over periods diafenthiuron 50 WP @ 0.05% was found most effective for the control of mites. However, treatments which were found next in order of efficacy were abamectin 1.9 EC @ 0.0019% and propargite 57 EC @ 0.057%. Ethion 50 EC @ 0.05% was found least effective against this pest. The highest (823 kg/ha) seed yield was gained from the plots treated with diafenthiuron 50 WP @ 0.05% followed by abamectin 1.9 EC @ 0.0019% (815 kg/ha) and propargite 57 EC @ 0.057% (794 kg/ha).
