Abstract
A synergistic composite insecticide for preventing and treating rice borer and high-resistance plutella xylostella contains trans-cypermethrin, chlorpyrifos, 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 chlopyrifos.
Two, background technology
Theta-cypermethrin (theta-cypermethrin), 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, be mainly used in the control seedling arrange, cereal.The insect of 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.Be theta-cypermethrin missible oil but register the product that uses at present at home, do not have and other agriculture chemical compounding compositions.
Chlopyrifos (chlorpyrifos) chemical name is: O, O-diethyl-O-(3,5, the 6-trichloro-2-pyridyl) thiophosphate.Chlopyrifos is the broad spectrum type insecticide, have tag, stomach toxicity and fumigation action.Can prevent and treat tea geometrid, smaller green leaf hopper, cotten aphid, two-spotted spider mite, rice fulgorid, rice leaf roller, wheat mythimna separata and ox, sheep vermin and soil insect.
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 chlopyrifos 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 purpose of this invention is to provide multifunctional insecticide composition and its application of said composition that a kind of synergy prevents and treats the resistance lepidoptera pest, make full use of both mutual supplement with each other's advantages, 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.
2, technical scheme
A kind of Pesticidal combination, it is an active ingredient with theta-cypermethrin and chlopyrifos, wherein the weight ratio of theta-cypermethrin and chlopyrifos is 0.1～30: 0.5～60.
Effective ingredient is present in the composition with the synergy effective dose in this Pesticidal combination.
The weight ratio of theta-cypermethrin and chlopyrifos preferred 0.5～20 in this Pesticidal combination: 15～50.
The optimum weight ratio of theta-cypermethrin and chlopyrifos is 1～5: 15～20 in this Pesticidal combination.This Pesticidal combination is that active ingredient and insecticides adjuvant and excipient are mixed with missible oil, aqueous emulsion or microemulsion with theta-cypermethrin and chlopyrifos.
Above-mentioned Pesticidal combination is in the application that prevents and treats on the resistance lepidoptera pest, especially in the application that prevents and treats on the diamond-back moth and the snout moth's larva of rice.
The Pesticidal combination of theta-cypermethrin provided by the invention and chlopyrifos compared with prior art can produce higher cooperative synergism, and overcome and delayed pest resistance to insecticide, the expanding prevention spectrum, desinsection speed is fast, has reduced drug cost, has 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.
For achieving the above object, the present invention is by the network analysis to theta-cypermethrin and dursban insecticidal characteristic, make full use of both mutual supplement with each other's advantages, theta-cypermethrin and chlopyrifos 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 chlopyrifos).
The compound pesticide compositions of high-efficiency prevention and control lepidoptera pest of the present invention is made up of theta-cypermethrin and two kinds of active components of chlopyrifos and insecticides adjuvant, excipient, also can go into other auxiliary material simultaneously if desired.Auxiliary agent can adopt calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, polyoxyethylene polyoxy third rare block compound (as farming breast 33
#), the one or more combinations in the polyoxyethylene nonylphenol ether, 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.
Beneficial effect of the present invention
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 chlopyrifos 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.
