| 摘 要： | 田间试验结果表明:25%甲维.毒死蜱水乳剂1500~1800 mL/hm2对水稻白背飞虱具良好的防治效果,其中25%甲维.毒死蜱水乳剂1500 mL/hm2的控虫效果优于25%甲维.毒死蜱乳油同剂量的效果;明显低于吡蚜酮对白背飞虱的控制效果;药后1 d,25%甲维.毒死蜱水乳剂1500~1800 mL/hm2对田间主要蜘蛛有一定的杀伤率(46.51%~56.60%),但杀伤率低于25%甲维.毒死蜱乳油1500 mL/hm2和毒死蜱处理;药后15 d,25%甲维.毒死蜱水乳剂对稻田主要蜘蛛无杀伤作用。25%甲维.毒死蜱水乳剂防治水稻白背飞虱的剂量应不低于1800 mL/hm2。

| Abstract: | The field test results showed that applying 25% emamectin benzoate· chlorpyrifos EW 1500~1800 mL/hm 2 had good control efficiency on Sogatella furcifera in rice field,among them 25% emamectin benzoate· chlorpyrifos EW 1500 mL/hm 2 had better control efficiency on Sogatella furcifera than 25% emamectin benzoate· chlorpyrifos EC 1500 mL/hm 2,but had significantly lower control efficiency than pymetrozine.One day after treatment,25% emamectin benzoate· chlorpyrifos EW 1500~1800 mL/hm 2 had a certain killing role to the major predatory spiders in rice field,but its killing rate(46.51%~56.60%) was less than that of 25% emamectin benzoate· chlorpyrifos EC 1500 mL/hm 2 and chlorpyrifos treatment.Fifteen days after spraying,25% emamectin benzoate· chlorpyrifos EW had no killing effect on the main spiders in paddy field.The dosage of 25% emamectin benzoate· chlorpyrifos EW for the control of Sogatella furcifera in rice should be more than 1800 mL/hm 2. |
