| Abstract: | Indoor toxicity, effective duration and field experiment of Chlorantraniliprole SC and mixing EC to diamondback moth were determined. The results of indoor toxicity were respectively LC_(50)=0.81 mg/L and LC_(50)=0.71 mg/L. The effective duration of Chlorantraniliprole SC showed that the mortality was 64,10% relative to 49.38% of Chlorantraniliprole mixing EC after spaying 21 days in lab. Field control efficiencies were respectively 93.95% and 98.63% after spraying 7 days. |
