Abstract
The invention relates to a composite Fipronil and Ethofenprox insecticide comprising effective active constituents, auxiliary agent and solvent, wherein the effective active constituents include Fipronil and Ethofenprox by the weight ratio of 1-20 : 1-40. The insecticide can be used for controlling Chilo supperssalis, Laodelphax srtiatellus, Nilaparvata lugens, Sogatella furcifera and Cnaphalocrocis medinalis Guenee.
Description
Technical field:
The invention belongs to control pest agricultural chemicals, relate to the compounded pesticides that a kind of effective active composition is fluorine worm nitrile and ether chrysanthemum ester.
Background technology:
Paddy rice is the topmost cereal crops of China, and it is staple food with the rice that there is 65% above population in the whole nation.Paddy rice annual sowing area accounts for about 35% of national cereal crops sowing area.Whether the good harvest of paddy concerns grain market trend and the grain security situation that is restricting China to a great extent.Rice pest is the key factor that influences China's Rice Production, and it takes place and cause harm to be to increase the weight of trend in recent years, and a year generation area surpasses 6,667 ten thousand hectares, and percent of loss is up to 10%-30%.And in the rice pest integrated control process, the chemical agent method remains the important method of current rice pest control, yet many problems have also been produced in the chemical control process, as the generation of pest resistance to insecticide, kill a large amount of non-target organisms, destroy the ecological balance, some follow-up toxic actions of causing of the use of some persistent pesticide particularly, wide attention.But the control of inada's disease insect pest also is difficult to leave agricultural chemicals at present, improves rice output and quality, also will use agricultural chemicals inevitably.
The use of chemical pesticide has not only caused serious farmland ecological environment and water pollution, and has directly increased the residual quantity of agricultural product toxic chemical substances, and human health is caused serious threat.How to improve the drug effect of chemical pesticide, reduce the consumption of chemical pesticide, alleviate the medicine of learning to farm, become the problem that people need solve farmland ecological environment and water pollution.
Fluorine worm nitrile, common name Fipronil, have another name called sharp strength spy, be a kind of Phenylpyrazole insecticides, insecticidal spectrum is wide, to insect based on stomach poison function, have concurrently and tag and certain systemic function, its insecticidal mechanism is to hinder the chloride metabolism of insect γ-An Jidingsuan control, therefore important pests such as aphid, leafhopper, plant hopper, lepidopterous larvae, fly class and coleoptera is had very high insecticidal activity, and crop is not had poisoning.
Ether chrysanthemum ester, common name Ethofenprox has another name called trebon, benzyl oxide chrysanthemum ester, Li Laiduo, according to phenin.Be the efficient pyrethrin pesticide of pressing KCC to find, succeeded in developing and realized the industrialization of ether chrysanthemum ester in 1987 in early eighties by Mitsui east.The insecticidal mechanism of this product is to suppress the Na of the current potential door on the neural axon film
+Passage, belong to that a kind of insecticidal spectrum is wide, insecticidal activity is high, the speed of knocking down is fast, the longevity of residure is long, to characteristics such as crop safeties.It is the unique pyrethroid pesticide that on paddy rice, uses of present state approval.
Be used alone chemical pesticide not only in the pest control cost higher, be repeatedly used and also can make insect produce resistance, influence drug effect.Agriculture chemical compounding is raising preventive effect and expanding prevention object, slows down pest resistance to insecticide, reduces a kind of effective ways that pollute, reduce residue of pesticide, still, how to select chemical pesticide to carry out compatibility, and is then especially noticeable.At present, the compounded pesticides that fluorine worm nitrile and ether chrysanthemum ester are carried out does not appear in the newspapers as yet.
Summary of the invention
The objective of the invention is to: higher at cost in present use fluorine worm nitrile separately and the ether chrysanthemum ester pest control, reuse the practical problem that insect easily produces resistance, a kind of fipronil and etofenpronx mixed insecticide is provided.
The object of the present invention is achieved like this: a kind of fipronil and etofenpronx mixed pesticide, comprise effective active component, auxiliary agent and solvent, it is characterized in that: the effective active composition is fluorine worm nitrile and ether chrysanthemum ester, and the weight proportion of fluorine worm nitrile and ether chrysanthemum ester is 1～20: 1～40.
In the compounded pesticides that the present invention relates to, each effective active composition, auxiliary agent and solvent, the percentage by weight in compounded pesticides are: fluorine worm nitrile 1～20%; Ether chrysanthemum ester 5～40%; Auxiliary agent 5～20%; All the other are solvent.
In the compounded pesticides that the present invention relates to, the agent of fipronil and etofenpronx mixed pesticide plough is missible oil, or aqueous suspension agent.
The invention has the advantages that: after fluorine worm nitrile and ether chrysanthemum ester are composite, have notable synergistic and lasting control efficiency; Obtained to striped rice borer, small brown rice planthopper, brown planthopper, white-backed planthopper, rice leaf roller, etc. multiple rice grub wide spectrum, efficient, lowly pollute, the multifunctional insecticide agent of low-residual, significantly reduce consumption, spraying times and drug cost, and slowed down pest resistance to insecticide.
