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