摘要
三唑·吡EC对二化螟和稻飞虱的室内共毒系数分别为 1 36 .5 6和 1 34 .0 8。 1 1 2 5～ 1 5 0 0mL·hm-2对二化螟的大田防效为 86 .2 3%～ 98.75 % ,对稻飞虱药后 1d的防效为 47.80 %～ 91 .0 7% ,药后 7d为 92 .0 7%～ 98.2 2 % ,药后 30d为 95 .37%～ 1 0 0 %。具有速效性强。
The effect of triazophos-imidacloprid 20% EC against Chilo suppressalis, Sogatella fucifera and Nilaparvata lugens was studied. The results showed that the cotoxicity coefficient of triazophos-imidacloprid EC is 136.56 against Chilo suppressalis, it is 134.08 against Sogatella fucifera and Nilaparvata lugens. The effect of triazophos-imidacloprid EC used at the level of 1125～1500mL·hm -2 in the fields was 86.23%～98.75% against Chilo suppressalis. The effect was 47.80%～91.07% on the first day after treatment, it was 92.07%～98.22% on the 7th day after treatment, and it was 95.37%～100% on the 30th day after treatment against Sogatella fucifera and Nilaparvata lugens. Triazophos-imidacloprid possesses fast effect and long persistence in controlling pests.
