Abstract
The invention discloses a pesticide preparation with rotenone and fluacrypyrim as the main raw materials, which is mixed prepared by 0.05 to 70 percent of rotenone, 1 to 70 percent of fluacrypyrim and a promoter of the left percentage. The invention makes use of the synergism action of rotenone and fluacrypyrim to realize the aims of overcoming the insecticide resistance of evil mites, enlarging the using range of the medicament and prolonging the effect period, which can greatly reduce the poisoning effect to various natural enemies and is favorable for reducing the pesticide effect to the ecological environment.
Description
Technical field
The invention belongs to technical field of pesticide.Be specifically related to a kind of rotenone and fluacrypyrim mixed insecticide preparation.
Background technology
The evil of control agricultural at present mite is to use chemical miticide mostly, causes the evil mite easily and develops immunity to drugs, and has killed a large amount of useful natural enemies simultaneously, causes the rampant harm of evil mite, and contaminated environment easily causes the person poultry poisoning.Therefore the miticide of the friendly type of development environment is pressing for of agricultural production.
Rotenone is a kind ofly to have good acaricidal activity from the compound in plant derris root, the grey green soy bean blade, and very fast degraded in environment does not injure natural enemy and other non-target organism, and its shortcoming is unstable, and the processing formulation is less.
Fluacrypyrim (fluacrypyrim) is first methoxy acrylic miticide, and is efficient to the evil of the resistance on present agricultural mite.
Be expected to obtain to overcome harmful mite pesticide resistance at the research of above-mentioned two kinds of aspects that insecticide is mixed, the expanding prevention spectrum reduces consumption, delays the medicament lasting period, and the miticide that is mixed of the rotenone with multiple formulation.
Summary of the invention
The objective of the invention is to fill up the blank of prior art, a kind of efficient, safe rotenone and the fluacrypyrim miticide that is mixed is provided.By rationally being mixed between rotenone and the fluacrypyrim, the expanding prevention spectrum improves drug effect, reduces dosage, alleviates the pollution to environment.
Technical scheme of the present invention provides a kind of rotenone and fluacrypyrim mixed insecticide preparation, by rotenone by weight 0.05～70%, fluacrypyrim by weight 1～70% and the additive mixture of surplus form.
As preferred version of the present invention, described mixed insecticide preparation by rotenone by weight 0.5～50%, fluacrypyrim by weight 2～55% and the additive mixture of surplus form.
Described rotenone can be former medicine, contain one or more of the plant extracts of rotenone or rotenone preparation, using when multiple, and total usage amount can not be greater than the maximum of deal.
Described fluacrypyrim can be former medicine and/or preparation, and when use was multiple, total usage amount can not be greater than the maximum of deal.
The invention has the beneficial effects as follows:
1. after rotenone and fluacrypyrim are mixed, both can overcome the shortcoming that fluacrypyrim is easy to generate resistance, and can keep the biopesticide advantage of mixture again, and can widen the scope of application of medicament, prolong the lasting period, improve drug effect, the resistance management that does harm to mite was played an important role.
2. after rotenone and fluacrypyrim were mixed, the dosage of mixture reduced, and had reduced production cost under the prerequisite that drug effect improves.
3. because the compatibility and the reasonable mixture ratio of required each material of such miticide of preparation can greatly reduce the toxic action to various natural enemies, help alleviating influence to ecotope.
