Popis:	Field experiments were carried out at Zonal Agricultural and Horticultural Research Station, Navile, Keladi Shivappa Nayaka University of Agricultural and Horticultural Sciences, Shivamogga, Karnataka India during kharif 2020 and 2021. A total of seven acaricides were evaluated, and the results revealed that spiromesifen 22.9SC @ 0.8 ml/ l was the most effective in reducing mites (87.21% reduction) followed by diafenthiuron 50WP @ 1.0 gm/ l (84.49%). Maximum marketable pod yield was obtained with spiromesifen 22.9SC (21.36 t/ ha) and it was closely followed by diafenthiuron 50WP (20.15 t/ha). Maximum cost benefit ratio was observed with these, and thus spiromesifen 22.9SC @ 0.8 ml/ l and diafenthiuron 50WP @ 1.0 g/ l can be recommended against mites in yard long bean.
