Description

一种用于玉米生长后期叶斑病防治前移的方法
技术领域
本发明属于玉米病害防治技术领域，特别是涉及一种用于玉米生长后期叶斑病防治前移的方法。
背景技术
扬彩(18.7％丙环·嘧菌酯SC)结合了嘧菌酯和丙环唑两者的特点，活性成分可在叶片内通过木质部再分布，有效抵御病菌侵染；通过跨层传导、内吸进入植物体内并通过木质部向顶传导从而保护新生组织；具体表现在：叶绿素变化，谷胱甘肽还原酶变化，PEPC变化，脯氨酸变化，可溶性糖、可溶性蛋白、MDA、SOD、POD、CAT酶的变化。经过多年测定产量，平均增产约10％。
福戈(40％氯虫·噻虫嗪水分散粒剂)有效成分为氯虫苯甲酰胺和噻虫嗪，前者对螟虫等鳞翅目害虫活性高，后者对飞虱等同翅目害虫杀灭效果好，两者混合后能大大提高对方的活性。福戈可以杀灭多种玉米害虫，除对鳞翅目害虫防效很好外，对鞘翅目、双翅目、半翅目、直翅目等害虫也有较好的防效，也可防治飞虱、蚜虫、粉虱、叶蝉等刺吸式口器害虫。福戈具有良好的内吸传导性，一次施药持效期为14-21天，可以减少用药次数，降低生产成本，减少劳动时间。福戈耐雨水冲刷，喷药后1小时下雨，不影响杀虫效果；在多雨季节施用，不会影响使用效果。它不仅对操作者和环境毒性低，而且保护害虫天敌，特别是对水生生物安全。噻虫嗪可激活植物抗逆性蛋白酶的活性，使作物茎秆和根系更加健壮，使植株健壮生长。
在玉米病虫害防治生产中，不同品种之间及不同浓度的农药处理，都会对玉米生长引起不同效果。
发明人在长期玉米种植过程中，发现杨彩+福戈或醚菌酯+福戈的混合液使用具有一定的增效作用，并且发明人力求探索一种操作简便的用于玉米叶斑病防治效果好的方法。
发明内容
本发明为克服现有技术中的不足，提出一种用于玉米玉米生长后期叶斑病防治的前移技术方法。
本发明所提供的技术方案为：
一种用于米生长后期叶斑病防治前移的方法，包括以下步骤：
(1)第1次施药：在玉米大喇叭口时期，施用18.7％丙环·嘧菌酯SC1000-2000倍+40％氯虫·噻虫嗪WDG 800-1000倍的混合液1次；
(2)第2次施药：待第1次施药7-10天后，再施用50％醚菌酯WP1000-2000倍+40％氯虫·噻虫嗪WDG 800-1000倍的混合液1次。
作为优选，所述混合液施用的方式为喷雾施用。
本发明还提供了所述的用于米生长后期叶斑病防治前移的方法在玉米中的应用。
与现有技术相比，本发明具有如下有益效果：
(1)本发明的方法中采用低浓度的扬彩+福戈或醚菌酯+福戈的混合液，对玉米安全性好，具有明显的增效作用，防治玉米螟、玉米大斑病、玉米小斑病效果优异，并且本发明的方法还具有一定的增产效果。
(2)本方法操作简单，适于在玉米种植区进行大规模推广和应用。
