Control Effects of 21% Etofenprox·Pymetrozine SC to Sogatella furcifera and Its Safety to Major Spiders in Paddy Field
摘要
Abstract
The control effects of 21％ Etofenprox · Pymetrozine SC to Sogatellafurcifera and its safety to major spiders in paddy field were tested. The results showed that the control effect of 21％ Etofenprox · Pymetrozine SC at the dosage of 375 ～600 mL/hm2 against Sogatella furcifera was 72. 14％ ～ 82.87％, 95.89％ ～ 97.07％, 95.69％ ～ 97.52％ respectively on the first day, 7th day,21st day after spraying, which was better than or similar to that of Permethrin and Pymetrozine. The application of 21％ Etofenprox ·Pymetrozine SC 375 ～600 mL/hm2 had great killing effect on micro - spider, little effect on tarantula, while basically no effect on theridiid. Therefore, applying 21％ Etofenprox · Pymetrozine SC 375 ～600 mL/hm2 had high, quick and long control effects against Sogatella furcifera on rice, and was safe to the main spiders in paddy field. The optimum dosage of applying 21％ Etofenprox · Pymetrozine SC was 375 mL/hm2, and the optimal time of applying 21％ Etofenprox · Pymetrozine SC was at the peak stage of 1 ～3 instar nymphs of Sogatella furcifera.关键词
