Abstract
The present invention relates to a method for mixing pesticides, which is used for mixing a nimbin pesticide and a benzoylurea pesticide as main raw materials. In the mixture, the synergistic function of the nimbin pesticide and benzoylurea pesticide is used for overcoming the chemical resistance of destructive insects, so that the phytotoxicity of the benzoylurea pesticide is avoided, and the application ranges of the pesticides are enlarged, the dosages of the chemical pesticides are reduced, and the effect sustaining time of the pesticides is prolonged.
Description
Technical field
The invention belongs to mixed pesticide and preparation method thereof, relate to nimbin particularly and benzoyl urea insecticide is mixed.
Technical background
Because the long-term single insecticide that uses a certain type that depends on of people, insect is easy to generate pesticide resistance, cause the dosage of chemical insecticide sharply to increase, the capacity contaminated environment, the natural enemy of a large amount of kill pests, insect can develop immunity to drugs after the long period uses, and causes the wildness harm of insect, easily causes the person poultry poisoning.
Nimbin is a kind of compound from plant seal chinaberry, has good insecticidal activity, and is almost all effective to all pest, very fast degraded in environment, not injuring natural enemy and other non-target organism, is a kind of universally acknowledged outstanding biopesticide, and its shortcoming is unstable.Benzoyl urea insecticide is the insecticide of a class high-efficiency low-toxicity, and especially efficient to lepidoptera pest, selectivity is strong, and its shortcoming is to play a role slowly, crop in cruciferae is easily produced poisoning.
