The agricultural pesticide combination disclosed by the invention has a significant synergistic effect, and is especially suitable to be used for controlling rice leaf rollers and cotton bollworms in lepidoptera.
Description
Technical field
The invention belongs to the agricultural insecticide field.
Background technology
Rice leaf roller (Cnaphalocrocis medinalis), striped rice borer (Chilo suppressalis) and paddy stem borer (Tryporyza incertulas) are the primary pests that rice safety is produced, because generating capacity is large, insect pest situation is complicated and pesticide resistance rises, cause certain difficulty for prediction and production control in recent years; Cotton bollworm (Helicoverpa armigera) host plant has section more than 20 more than 200 to plant, and all there is generation in Chinese cotton region and growing vegetables district.Cotton region, the Huanghe valley, cotton region, the Yangtze river basin are injured heavier.Filter out the novel pesticide that effectively to prevent and treat rice leaf roller, striped rice borer, paddy stem borer and cotton bollworm and seem particularly important
ZJ3757 belongs to the O-formammidotiazol-benzamide insecticide, is the compound that my company develops voluntarily, and chemical structural formula is as follows:
