Description

technical field [0001] The present invention relates to a thermal mist of a binary insecticidal composition comprising emamectin emamectin (hereinafter referred to as active ingredient I) and chlorpyrifos (hereinafter referred to as active ingredient II) as active ingredients and a preparation method thereof, belonging to the field of pesticide preparations. Background technique [0002] The emamectin benzoate as the active ingredient I is a new type of high-efficiency, broad-spectrum antibiotic insecticide and acaricide with a unique mechanism of action, acting on γ-aminobutyric acid and interfering with the neurophysiological activities of pests. It is not easy for pests to develop resistance to pesticides. It has strong stomach poisoning and contact killing effects on pests. It has no systemic properties, but can effectively penetrate into the epidermal tissue of crops. It is resistant to rain and has a long lasting effect. It has good control effect on pests with chewing...

Problems solved by technology

[0008] In arid areas or some hills and mountainous areas, the main crops planted in these areas are corn, sugarcane, cassava and other high-stalk grains, economic crops, in addition to a large number of fruit trees, economic forests, etc., in these areas, traditional methods are used to apply pesticides The main problems are water shortage, complex terrain, etc. When controlling pests and diseases, the water source is often quite a long distance away from the application site, and the complex terrain makes the efficiency of pesticide application very low, and it is easy to miss spraying and reduce the control effect.
