Problems solved by technology

Through the test of the systemic effect of acetamiprid and imidacloprid on aphids, and the comparison of the mode of action on rice stem borers, it was found that acetamiprid has a strong systemic effect on crops, and the effect of foliar treatment is better than that of other similar pesticides, but its soil The treatment effect is poor, so compounding it with imidacloprid can better exert the drug effect and improve the comprehensive control ability of pesticides

Abstract

The invention discloses a pesticide composition of imidacloprid and acetamiprid aqueous emulsion, wherein the composition comprises imidacloprid and acetamiprid as two effective components, and the mass ratio of the imidacloprid to the acetamiprid is 3:2. The accumulated mass percent of the imidacloprid and the acetamiprid accounts for 25 to 50 percent of the gross mass. The preparation form of the pesticide composition is aqueous emulsion. The pesticide composition of the imidacloprid and acetamiprid aqueous emulsion of the invention has strong security, environmental protection and low price and has the characteristics of low pesticide damage, low toxicity, easy dilution, difficult burning, difficult explosion, easy use, easy measurement, favorableness for environmental protection and the like.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition with imidacloprid and acetamiprid as active ingredients. Background technique [0002] At present, in the structure of pesticide formulations in my country, old formulations such as emulsifiable concentrates and wettable powders are still the main ones, among which emulsifiable concentrates account for nearly 50% of the total. The emulsifiable concentrate contains a large amount of organic solvents such as toluene, xylene, and methanol. These organic solvents will cause harm to the human body during the processing, packaging, and use of the emulsifiable concentrate, reduce the quality of the crops, and affect the foreign exchange earnings of the crops. At the same time, they also pollute the soil, water source etc. The use of EC on vegetables and fruit trees has been strongly resisted in developed countries. Organic solvents have a low flash point and are flamm...
