Bio-efficacy of Clofentezine 50SC against two spotted spider mite, Tetranychus urticae Koch on rose cv. First Red in polyhouse
Bio-efficacy of Clofentezine 50 SC along with standard acaricides dicofol and abamectin was evaluated against Tetranychus urticae on rose cv. First Red under polyhouse conditions. Clofentezine 50 SC at the rate of 300 g a.i/ha was most effective in controlling T. urticae in rose during two consecutive seasons (October-November 2009 and March-April 2010). The efficacy of Clofentezine 50 SC was at par with the tested standard acaricide, abamectin (8.55 g.ai/ha) and superior over dicofol (231.25 g.ai/ha.) Clofentezine 50 SC was also found to be relatively safe to the natural enemies and was non-phytotoxic to rose.
