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 3 6.5 6和 1 3 4.0 8。1 1 2 5～ 1 5 0 0mL/hm2 三唑·吡EC对二化螟的大田防效为 86.2 3 %～ 98.75 % ,对稻飞虱的防效 :药后 1d为 47.80 %～ 91 .0 7% ,药后 3 0d为 95 .3 7%～ 1 0 0 %。该药剂具有速效性强。
The results showed that the cotoxicity coefficient of Triazophos-imidacloprid EC was 136.56 to Chilo suppressalis, it was 134.08 to Sogatella fircifera and Nilaparvata lugens. The control effect of Triazophos-imidacloprid EC used at 1 125～1 500mL/hm\+2 in the fields was 86.23%～98.75% on Chilo suppressalis, it was 47.80%～91.07% on S. furcifera and N. lugens on the first day after treatment, and 95.37%～100% on the 30th day after treatment. Triazophos-imidacloprid possessed fast and long control effect on above insect pests.
