Abstract
A synergistic composite insecticide for preventing and treating rice borer and high-resistance plutella xylostella contains trans-cypermethrin, acephate, assistant and excipient.
Description
One, technical field
The present invention relates to a kind of Pesticidal combination and uses thereof, especially a kind of is the Pesticidal combination and the application thereof of main active with theta-cypermethrin and orthene.
Two, background technology
Theta-cypermethrin (theta-cypemethrin), chemical name: (IR is trans) S and (IS is trans) R-alpha-cyano-(3-benzyloxy phenoxy base)-3-(2, the 2-dichloroethylene)-2,2-dimethyl cyclopropane carboxylic acid ester.
Theta-cypermethrin is a kind of widely used pyrethroid insecticides, is high-efficient broad-spectrum insecticide, and tool is tagged and the insecticide of stomach poison function, prevents and treats a lot of insects.Effective especially to coleoptera and Lepidoptera, the insect that is mainly used in control has meadow pretty young woman at night, rice leaf roller, striped rice borer, rice leafhopper, plant hopper, stinkbug, cutworm, aphid, corn borer, cotton bollworm, pink bollworm, looper, thrips, aleyrodid, flea beetle, tomato moth, dive fly, moth-eaten moth, gypsymoth, tent caterpillar and cured coccid etc.Also can prevent and treat animal body epizoa, sheep lice and ked, directly be sprayed onto animal on one's body or on the building, can knock down rapidly and lasting control around fly.
Theta-cypermethrin decomposes in plant corpus soon, and residual hazard is low, to the person poultry safety, environment is had no adverse effects.Register the product that uses at present at home and be theta-cypermethrin missible oil, do not have and other agriculture chemical compounding compositions.
Orthene (acephate) is a kind of wide spectrum low toxicity Insecticidal and acaricidal agent, has interior suction, tags, stomach toxicity and certain fumigation action, and its desinsection principle is to suppress the insect acetylcholinesterase.Lepidoptera, Homoptera, Semiptera insect and mite class on the crops such as paddy rice, cotton, wheat, vegetables, fruit tree, tea, mulberry all there is the better prevention effect.
The synergistic complex of agricultural chemicals is expanding prevention spectrum and the effective measures that improve preventive effect, still finds no the Pesticidal combination that closes theta-cypermethrin and orthene up to now.
Lepidoptera pest as cabbage caterpillar, cotton bollworm, aphid, beet armyworm, the snout moth's larva of rice etc., increases gradually in present resistance, and the agent of agricultural chemicals list descends gradually to the effect of control of insect, and agriculture chemical compounding can obviously improve drug effect, and delays the generation of pest resistance.
Three, summary of the invention
1, goal of the invention
But the multifunctional insecticide composition that the purpose of this invention is to provide a kind of high-efficiency prevention and control resistance lepidoptera pest, and the application of this Pesticidal combination.
2, technical scheme
For achieving the above object, the present invention is by the network analysis to theta-cypermethrin and orthene insecticidal properties, make full use of both mutual supplement with each other's advantages, theta-cypermethrin and orthene is composite according to certain ratio, obtain a kind of new and effective multifunctional insecticide composition.The various pests that this insecticide antagonism diamond-back moth, the snout moth's larva of rice, beet armyworm etc. are easy to generate resistance has good preventive effect; And the inhibition insect is to the pesticide resistance generation of unitary agent (theta-cypermethrin or orthene).
A kind of Synergistic insecticidal compositions that contains theta-cypermethrin and orthene is characterized in that by theta-cypermethrin and orthene be active component, and wherein the weight ratio of theta-cypermethrin and orthene is: 0.1～30: 0.5～60.
The preferred weight ratio of described theta-cypermethrin and orthene is 0.5～20: 10～45.
The optimum weight ratio of described theta-cypermethrin and orthene is: 1～5: 15～20.
It is active component and an amount of insecticides adjuvant and formulated missible oil, aqueous emulsion or the microemulsion of carrier with theta-cypermethrin and orthene.
Synergistic insecticidal compositions of the present invention is in the application that prevents and treats on the resistance lepidoptera pest, especially in the application on the control diamond-back moth and the snout moth's larva of rice.
Auxiliary agent can adopt the one or more combinations in calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, polyoxyethylene polyoxy third rare block compound (as the newborn 33# of farming), the polyoxyethylene nonylphenol ether, and excipient comprises cyclohexanone, dimethylbenzene, solvent naphtha, water, antifreezing agent (as propane diols), deionized water etc.Above auxiliary agent, excipient and other auxiliary material can singly be used or and use.
3, beneficial effect
The invention provides the Pesticidal combination of a kind of theta-cypermethrin and orthene, it compared with prior art can produce higher cooperative synergism, overcome and delayed pest resistance to insecticide, the expanding prevention spectrum, desinsection speed is fast, reduce drug cost, alleviated toxicity.
The present invention especially can be used for preventing and treating the diamond-back moth and the snout moth's larva of rice of high resistance, and its effect is used apparently higher than its single agent.
Pesticidal combination of the present invention compared with prior art produces following beneficial effect: (1) is compared with single agent, and the said composition antagonism lepidoptera pest such as the snout moth's larva of rice, resistance diamond-back moth etc. has notable synergistic, obviously improved control efficiency; (2) one medicines are controlled more, and a dispenser can prevent and treat various pests simultaneously, reduce control recruitment cost; (3) alternative high-toxic pesticide; (4) have concurrently quick-acting and long-acting; (5) compare with orthene or the agent of theta-cypermethrin list, produce and the use cost reduction; (6) suppress the resistance enhancing of lepidoptera pest to agricultural chemicals; (7) reduction is to the toxicity of warm blooded animal.
