四种杀虫剂防治灰钝额斑螟药效示范试验

THE DEMONSTRATION EXPERIMENT OF FOUR PESTICIDES EFFICACY TO BAZARIA TURENSIS RAGONOT IN THE FIELDS

田间药剂防治示范试验结果表明,药剂示范区1.8%阿维菌素EC和25%得奇EC防治白刺灰钝额斑螟的效果良好,平均校正防效为97.16%和92.74%。草毒蛾SC和类产碱SC对白刺灰钝额斑螟的防治效果较差,平均校正防效为69.87%和49.11%。因此,1.8%阿维菌素EC、25%得奇EC可作为防治白刺灰钝额斑螟的有效药剂在生产上推广使用。

The demonstration experiment of four Pesticides efficacy to Bazaria turensis Ragonot in the fields were conducted.The results showed that control effect of 1.8% Avermectin EC and 25% Fenpropathrin-Phoxim EC which the average correction mortality rate were 92.74% and 97.16% were significantly better than ones of Gynaephora ruoergensis chou et yin Nuchear polyHedrosis rirus Sc and Pseudomonas pseudoalcaligenes SC,which the average correction mortality rate were 49.11% and 69.87%,in the demonstration areas.Therefore,1.8% Avermectin EC and 25% Fenpropathrin-Phoxim EC pesticides can be used in the agricultural production to control the larva of Bazaria turensis.
