在江苏省句容市的田间试验结果表明,醚菊酯、氟硅菊酯防治秧田灰飞虱均具有速效性好、持效期长的优点。药后1～3d,10%醚菊酯水乳剂1500～2250ml/hm2对灰飞虱的防治效果为86.34%～96.30%,10%氟硅菊酯乳油750～2250ml/hm2对灰飞虱的防治效果为88.78～97.10%%,均明显好于对照药剂吡蚜酮和毒死蜱的效果;药后7d,10%醚菊酯水乳剂1500～2250ml/hm2、10%氟硅菊酯乳油1500～2250ml/hm2对灰飞虱的防治效果为82.53%～93.58%,与对照药剂吡蚜酮对灰飞虱的防治效果相仿,明显好于对照药剂毒死蜱,在相同用量下氟硅菊酯防效好于醚菊酯。
The field experiment in Jurong, Jiangsu Province showed that the ethamefloxacin and silafluofos-methyl had the advantages of good quick-acting and long-lasting effect in the control of planthoppers. The control effect of 10% Ethephon aqueous emulsion 1500 ~ 2250ml / hm2 on Laodelphax striatellus was 86.34% ~ 96.30% at 1 ~ 3 d after the treatment, and the control of Laodelphax striatellus with 10 ~ 2250 ml / hm2 of 10% The effect was 88.78 ~ 97.10 %%, were significantly better than the control agents pymetrozine and chlorpyrifos effect; 7 days after drug, 10% etofen in water emulsion 1500 ~ 2250ml / hm2, 10% The control effect of hm2 on Laodelphax striatellus was 82.53% -93.58%, which was similar to that of the control agent pymetrozine on the control of Laodelphax striatellus and was significantly better than that of the control drug chlorpyrifos. Under the same dosage, Inulin.
