Description

用于防治小菜蛾和美洲斑潜蝇的无公害农药
本发明涉及一种农药,更准确地说,是涉及一种用于防治小菜蛾和美洲斑潜蝇的无公害农药。
现有的杀虫剂农药,如“氟铃脲”,属新型酰基类杀虫剂,击倒力强,杀虫速度比其它酰基脲类杀虫剂迅速,具有较高的接触杀卵活性,用药成本较低,高效、高选择性、低毒、低残留,与环境相溶性好,对小菜蛾有较好防效,但对美洲斑潜蝇防治效果较差,且在昆虫生活周期中敏感阶段的作用范围窄,致使该杀虫剂在农业中的应用受到限制。其它杀虫剂农药,如“阿维菌素”,属大环内脂双糖类化合物,具有独特的杀虫机理,由于它对小菜蛾和美洲斑潜蝇有较高防效,且无公害,而受到农业植保部门的日益重视,但因其单一反复应用,抗药性发展较快,药效下降,用药成本增加,同时由于其价格昂贵,作用速度缓慢,所以,至今在农业生产中推广仍有一定困难。如“啶虫脒”,属类烟碱化合物,高效低毒、低残留,作用速度快,对小菜蛾和美洲斑潜蝇有较好防效,但因该杀虫剂刚刚在我国开发成功,价格昂贵,且杀虫谱较窄,而使该杀虫剂的应用量相对不大。如“42%辛·氟铃脲乳油和20%氟铃·辛乳油”,均系杀虫剂辛硫磷和氟铃脲的复配组合物,它们都已在中华人民共和国农业部农药检定所1999年《农药登记公告》中公告出来,而且都已投产应用,其农药登记号分别为LS992040和LS99658,它们主要应用到棉花棉铃虫的防治上,虽然有较好的防治效果,但容易杀伤天敌,有一定公害,同时,又因其组合物中的辛硫磷对高梁、黄瓜、菜豆等作物有一定药害。
本发明的目的是为了提供一种用于防治小菜蛾和美洲斑潜蝇的无公害农药,它与现有技术相比,能产生较高的协同效应,能克服和延缓抗药性,杀虫速度较快,对作物无药害,与环境相溶性好,用药成本较低。
解决本发明的目的采取的技术方案是:用于防治小菜蛾和美洲斑潜蝇的无公害农药,主要采用一定量的氟铃脲,加入一定量的阿维菌素或啶虫脒,辅以适量的溶剂、乳化剂、渗透剂和/或增效剂等助剂配制而成。其配方范围为氟铃脲0.2%-5%,阿维菌素0.1%-4%或啶虫脒0.2%-5%,乳化剂2%-25%,渗透剂和/或增效剂0%-20%,余量为溶剂。
上述发明的用于防治小菜蛾和美洲斑潜蝇的无公害农药,可广泛应用于棉花、果树、蔬菜等作物,可有效防治小菜蛾和美洲斑潜蝇等多种害虫。
本发明的积极效果是:
1、能产生较高的协同效应,能克服和延缓抗药性;
2、杀虫速度较快,用药成本较低;
3、对作物无药害,与环境相溶性好。
下面将通过优选的实施配方对本发明作进一步的说明:
配方1:氟铃脲0.2%,阿维菌素0.1%,乳化剂25%,渗透剂20%,余量为溶剂。
配方2:氟铃脲5%,阿维菌素0.1%,乳化剂10%,余量为溶剂。
配方3:氟铃脲0.8%,阿维菌素0.7%,乳化剂14%,增效剂10%,余量为溶剂。
配方4:氟铃脲0.2%,啶虫脒5%,乳化剂10%,增效剂15%,余量为溶剂。
配方5:氟铃脲5%,啶虫脒02%,乳化剂15%,渗透剂和增效剂10%,余量为溶剂。
配方6:氟铃脲0.8%,啶虫脒0.8%,乳化剂10%,渗透剂20%,余量为溶剂。
配方7:氟铃脲2.3%,阿维菌素0.3%,乳化剂15%,余量为溶剂。
配方8:氟铃脲2%,啶虫脒1%,乳化剂10%,余量为溶剂。
