Among all the pesticides tested, diafenthiuron 50 WP@0.05% were found most effective in controlling the S. spinki. The next best treatment was chlorfenapyr 10 SC@0.015% and fenpyroximate 5 SC@0.005% in terms of a cent reduction of sheath mite population. The highest grain and straw yield was recorded in the treatment diafenthiuron 50 WP@0.05% which were followed by chlorfenapyr 10 SC@0.015% and fenpyroximate 5 SC@0.005%. In terms of ICBR the treatment diafenthiuron 50WP@0.05% was found most superior over the rest of the treatments.
