Evaluation of hexythiazox 5.45 EC against red spider mites (Tetranychus urticae) on okra

Abhishek Shukla

An experiment was conducted to evaluate the performance of hexythiazox 5.45 EC against red spider mites (Tetranychus urticae) on okra and to observe its phytotoxicity at higher doses. The treatments included two spray applications of acaricide hexythiazox 5.45 EC @ 15, 20 & 25 g a.i. / ha, propargite 57 EC 850 g a.i. /ha, fenpyroximate 5 EC 25g a.i. /ha and an untreated control (water spray). Observations on pre and post treatment populations of Tetranychus urticae were recorded after 3, 7, 14 and 21 days of spray. Two spray applications were given to the crop at ETL level of the red spider mites. All the treatments registered significantly lower population of red spider mites as compared to untreated control. Fenpyroximate 5 EC @ 25g a.i./ha proved the best treatment for the control of the pest, however, treatments viz., propargite 57 EC 850 g a.i /ha and hexythiazox 5.45 EC @ 25 g a.i./ha were also observed to be effective treatments in most of the observations.
