Abstract:
A study on the Bioefficacy of acaricides against red spider mite, Tetranychus macfarlanei infesting soybean was conducted. Six new acaricides viz., propargite, fenazaquin, spiromecifen, diafenthiuron, fenpyroximate and chlorfenapyr along with a standard check dicofol were evaluated. Among them Propargite 57 EC @ 427.50 a.i./ha proved to be highly effective in reducing the mite population with highest yield of 21.74 q/ha and also had highest C: B ratio of 1: 3.91 followed by spiromecifen 22.9 SC @ 91.60 a.i./ha which registered yield of 18.66 q/ha and C: B ratio of 1: 3.28.
Keywords: Arthropod pests Management Tetranychus macfarlanei
