Abstract
The invention discloses a pesticide preparation with rotenone and cyromazine as the main raw materials, which is mixed prepared by 0.05 to 70 percent of rotenone, 1 to 80 percent of cyromazine and a promoter of the left percentage. The invention makes use of the synergism action of rotenone and cyromazine to realize the aims of making up the defects of single agent pesticide, overcoming the insecticide resistance of evil mites, improving the medicament effect and enlarging the using range of the medicament. The mixed agent is of lower pesticide usage dose and remarkably higher control effect. The invention has an important significance for the development and application of natural insecticide.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to a kind of rotenone and d-allethrin mixed pesticide preparation.
Background technology
Because the long-term single insecticide that uses a certain type that depends on of people, insect is easy to generate pesticide resistance, causes the dosage of chemical insecticide sharply to increase, and has not only increased production cost, and the natural enemy and the contaminated environment of a large amount of kill pests, cause the wildness harm of insect.
Rotenone is a kind of from the compound in plant derris root, the grey green soy bean blade, has good insecticidal activity, all effective to most of pest, consumption is low, very fast degraded in environment, not injuring natural enemy and other non-target organism, is a kind of outstanding biological insecticides, and its shortcoming is unstable.
Fly eradication amine (cyromazine) is a kind of selectivity insect growth regulator, IGR, and the growth of diptera and part coleopteron larva is had had strong inhibitory effects.Be mainly used in the latent fly (diptera Agromyzidae) of economic crops such as control danger to vegetables and pulse family, tobacco, flowers, rape, cotton, as Americal rice leaf miner, south american leaf miner, clover liriomyza bryoniae and leek, round onions, garlic root maggot etc.
The applicant expects that in a large amount of experimental studies acquisition can overcome pest resistance to insecticide, enlarges insecticidal spectrum, reduces consumption, the rotenone mixed insecticide with multiple formulation by after rotenone and fly eradication amine reasonably are mixed.
Summary of the invention
The objective of the invention is to fill up the blank of prior art, a kind of safe, rotenone and d-allethrin mixed pesticide preparation efficiently are provided.By rationally being mixed between rotenone and the fly eradication amine, enlarge insecticidal spectrum, improve drug effect, reduce dosage, alleviate pollution to environment.
Technical scheme of the present invention provides a kind of rotenone and d-allethrin mixed pesticide preparation, by rotenone by weight 0.05～70%, fly eradication amine by weight 1～80% 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%, fly eradication amine by weight 2～60% and the additive mixture of surplus form.
Described rotenone can be former medicine, contain the plant extract of rotenone or rotenone preparation one or more, using when multiple, total usage amount can not be greater than the maximum of weight content.
Described fly eradication amine can be former medicine and/or preparation, and when use was multiple, total usage amount can not be greater than the maximum of weight content.
The invention has the beneficial effects as follows:
Rotenone and d-allethrin mixed after, can overcome the shortcoming that fly eradication amine is easy to generate resistance, can widen the scope of application of medicament, improve drug effect.Resistance management to insect has important effect.
Rotenone and d-allethrin mixed after, not only kept numerous advantages of vegetable insecticide, and the dosage of mixture reduces, drug effect increases substantially, this mixture has great importance to the Application and Development of natural insecticide.
3. because the compatibility and the reasonable mixture ratio of required each material of this insecticides of preparation can greatly alleviate the toxic action to various pest natural enemies, little to the pollution of ecotope, help protecting the person poultry safety.
