Abstract

本发明涉及一种高效防治水稻纵卷叶螟和水稻螟虫的多功能复合杀虫剂，它是含敌百虫与氟虫腈两种活性成分混配型杀虫剂，敌百虫10％～59％与氟虫腈1％～10％的农药组合物，敌百虫86％～90％与氟虫腈1％～10％的农药组合物，亩用制剂量为25克－100克。该复配剂：(1)利用速效性强，无残留的高效防治鳞翅目害虫的敌百虫与广谱、持效期长、对抗药性害虫有特效的氟虫腈复配，充分发挥了各自的长处，且有明显的增效作用，降低的用药量和用药成本，减少用药次数。(2)抑制害虫抗药性的产生。(3)取代高毒农药的使用量，降低环境污染和农药在稻米中的残留。(4)两药剂复配降低了农药生产成本。

Description

含敌百虫、氟虫腈的杀虫组合物
(一)技术领域
本发明涉及一种防治水稻纵卷叶螟和水稻螟虫的农药组合物。
(二)背景技术
近年来水稻纵卷叶螟发生量较大。长江中下游地区防治纵卷叶螟的防治适期正是多雨季节，往往农户错过防治适期，而使幼虫高龄化，难以防治。因此，需要开发一种防效高，长效的药剂。
现有技术：经过大田配比筛选试验得出敌百虫与氟虫腈复配有明显的增效作用。
(三)发明内容
1、技术问题：本发明克服现有农药的缺点，提供一种具有低毒、高效、价格低廉的防治鳞翅目害虫新配比的复配农药。
2、技术方案：本发明通过试验，得出敌百虫在复配剂中占比例为10％～59％，氟虫腈占比例为1％～10％，敌百虫在复配剂中占比例为86％～90％，氟虫腈占比例为1％～10％，亩用制剂量为25克-100克对水稻纵卷叶螟的防效达95％以上。
3、有益效果：敌百虫与氟虫腈复配，对水稻螟虫有较高的防治效果，保穗效果与治虫效果均达98.0％；可以延缓害虫抗药性的产生。
(四)附图说明：无
(五)具体实施方式
敌百虫为有机磷，是胆碱酯酶抑制剂。它能抑制虫体内胆碱酯酶的活力，使释放的乙酰胆碱不能及时分解破坏而大量蓄积，以致引起虫体中毒。具高效、低毒、低残留、水溶性等特点，对各种刺吸和咀嚼式口器害虫，如水稻螟虫、稻卷叶虫、稻包虫、棉花地老虎、果树刺蛾、蔬菜斜纹、菜青虫、玉米螟以及家蝇臭虫等有杀灭作用，可作为昆虫杀虫剂及抗寄生虫药物。
氟虫腈为GABA-氯通道抑制剂，属苯基吡唑类杀虫剂；杀虫谱广，具有触杀、胃毒和中度内吸作用。其杀虫机制在于阻碍昆虫γ-氨基丁酸控制的氯化物代谢，与现有杀虫剂无交互抗性，对有机磷、有机氯、氨基甲酸酯、拟除虫菊酯等有抗性的或敏感的害虫均有效。适宜的作物有水稻、玉米、棉花、香蕉、甜菜、马铃薯、花生等，既能防治地下害虫，又能防治地上害虫。既可用于茎叶处理和土壤处理，又可用于种子处理。主要防治对象包括蚜虫、叶蝉、鳞翅目幼虫、蝇类和鞘翅目等害虫推荐剂量下对作物无药害。是被众多农药专家推荐为代替高毒有机磷农药的首选品种之一。
敌百虫与氟虫腈以合适的比例复配后，不仅具有较好的速效性，且有较长的持效期，杀虫谱更广，延缓昆虫的抗药性的产生，是代替高毒有机磷农药的理想复配农药品种。
