Abstract:
The toxicity and field control efficacy of seven acaricides to the adult of carmine spider mite Tetranychus cinnabarinus were studied.The results showed that abamectin and emamectin benzoate had the highest toxicity among all the tested acaricides，with a LC50 value of 0.1300 mg/L and 0.7118 mg/L，respectively.Fenpyroximate and pyridaben showed relative low toxicity，with a LC50 value of 1.4808 mg/L and 3.1586 mg/L.Propargite showed lowest toxicity，with a LC50 of 356.1753 mg/L.The results of field efficacy test showed that the abamectin 1.8% EC，emamectin benzoate 1% EC and pyridaben 15% EC showed excellent efficacy，the control efficacy of 2 days was up to 98%，and 14 days was 100%.The control efficacy of 7 days and 14 days of propargite 40% EC and fenpyroximate 5% SC were up to 99%.240 g/L Spirodiclofen exhibit long persistence with a control efficacy of 99.94% in 14 days.
