Abstract

The invention discloses a nuisance free wheat insecticide with biological source which is prepared mainly from ethylicin, sophocarpidine, compound sodium nitrophenolate, cyhalothrin through watering, mixing uniformly to prepare aqueous emulsion. The insecticide is mainly used for the prevention and cure of damage by disease and insect for late phase wheat.

Description

technical field [0001] The invention belongs to a new type of pesticide, is a pollution-free pesticide, and is especially suitable for application in the middle and later stages of wheat growth. Background technique [0002] Wheat is the main food crop in my country, and the prevention and control of wheat diseases and insect pests plays an important role in improving the yield and quality of wheat. The main pests and diseases are: aphids, armyworms, red spiders, powdery mildew, head blight, leaf blight, etc. In the past, the pesticides for the prevention and control of diseases and insect pests were all chemical insecticides and fungicides, such as omethoate, methamidophos, Micarid, triadimefon, carbendazim, etc. After application, there are relatively large pesticide residues, and the toxic and side effects on people are relatively large. Contents of the invention [0003] The purpose of the present invention is to provide a kind of pollution-free biological source w...
