大螟、二化螟、三化螟这三种螟虫均有钻心虫的俗称,在水稻苗期危害均可造成枯心。水稻苗期用毒死蜱、阿维菌素等没有内吸传导性的药防治这些害虫,应在幼虫孵化高峰期还没有钻入稻株前施药,否则防效很差。氯虫苯甲酰胺、氟虫双酰胺等近几年进入市场的新药,对大螟、二化螟、三化螟等鳞翅目害虫均有极高的活性,而且具有较好的内吸传导性,持效期长达20天左右,特别适用于防治螟虫。生产上可以使用这两种药的单剂及其与阿维菌素的混配剂,如拜耳作物科学(中国)有限公司(电话:0571-87265252)的稻
Sesamia inferens, Sesamia inferens, Borer borer these three kinds of stem borers are commonly known as borer, the seedling damage in rice can cause dry heart. Rice seedling with chlorpyrifos, abamectin and other non-intrinsically conductive drugs to control these pests, larvae should peak at the peak of drilling has not yet invaded rice plants, or poor control. Chlorantranilon, flubendiamide and other new drugs into the market in recent years, the Sesamia inferens, Chilo suppressalis, Chilo suppressalis Lepidoptera pests have a high activity, and has good absorption conduction Sexual, persistence of up to 20 days, especially for the control of stem borers. A single dose of these two drugs and their combination with abamectin can be used in the production, such as rice from Bayer CropScience (China) Co., Ltd. (Tel: 0571-87265252)
