Abstract
The present invention discloses an insect disinfestation and sterilization composition containing thiamethoxam, fipronil and difenoconazole, wherein a mass ratio of the three active components such as thiamethoxam, fipronil and difenoconazole is 5-80:1-20:1-15. According to the present invention, the insect disinfestation and sterilization composition can be prepared into the seed coating agent, and can further be used for prevention and control of plant diseases and insect pests of corn, wheat or peanuts.
Description
Technical field
The invention belongs to technical field of plant protection, relate generally to a kind of pesticide-germicide ternary recompounded composite and seed coat agent thereof.
Background technology
Maize head smut, rough dwarf disease (small brown rice planthopper causes), grub, wireworm, aphid, small brown rice planthopper, take-all, banded sclerotial blight, loose kernel smut, aphid, grub, wireworm, Roots of Peanut maize ear rot, grub are damage by disease and insect important in agricultural production, often cause be short of seedling disconnected ridge and a large amount of dead seedling, very large on crop yield impact, time serious, underproduction 30%-50% even has no harvest.
For preventing and treating above-mentioned crop disease and insect, carrying out seed treatment is a kind of method preferably, and wherein seed coat agent is a kind of selection well.Seed coat agent is a kind of for crop seed dressing, the material with film forming characteristics, usually be processed into by active ingredient (insecticide, bactericide etc.), film forming agent, dispersant, warning colouration, antifreezing agent and other auxiliary agents, there is efficacy of a drug lasting period length, growth promoting effects, improvement quality, improve the advantage such as percentage of seedgermination, be a kind of diseases prevention, control worm, seed processing technology that sterilization, growth promoting effects combine together.
Therefore exploitation is needed a kind ofly to have high-efficiency low-toxicity, the environmentally friendly and double composite seed coat agent controlled of damage by disease and insect.
Summary of the invention
The object of the present invention is to provide a kind of high-efficiency low-toxicity, the double insecticidal and bactericidal composition controlled of environmentally friendly, sick worm.
