Abstract: 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).
