| 摘 要： | 田间试验结果表明:烯啶虫胺对水稻褐飞虱具有较好的速效性、持效性,药后3 d,50%烯啶虫胺WSG 22.5~52.5g/hm2对褐飞虱的防治效果为84.70%~90.81%;药后14~21 d,50%烯啶虫胺WSG 37.5~52.5 g/hm2对褐飞虱仍有89.84%~96.06%的防治效果。因此,从防治效果和防治成本的角度考虑,50%烯啶虫胺WSG防治水稻褐飞虱的适宜用量为37.5~52.5 g/hm2,防治适期在褐飞虱若虫高峰期,用水量不低于750 kg/hm2。 |

| Abstract: | The results of field test demonstrated that Nitenpyram had quick and persistent control effect on Nilaparvata lugens in rice field.The effect of 50% Nitenpyram WSG at the dose of 22.5~52.5 g/hm2 was 84.70%~90.81% on the third day after spraying;and the effect of 50% Nitenpyram WSG at the dose of 37.5~52.5 g/hm2 was still 89.84%~96.06% from the 14th day to the 21st day after application.So the suitable dosage of 50% Nitenpyram WSG for the control of Nilaparvata lugens in rice field should be 37.5~52.5 g/hm2 based on the control effect and control cost. |
