Description

A kind of Pesticidal combination that contains the pyridine of epoxy worm and pyrethroid insecticides

Technical field

The present invention relates to a kind of Pesticidal combination, particularly the Pesticidal combination of the pyridine of a kind of epoxy worm and pyrethroid insecticides belongs to technical field of compounded pesticide.

Background technology

The pyridine of epoxy worm is a kind of novel anabasine insecticide, by East China University of Science's initiative, chemical name: 9-(6-chloropyridine-3-yl) methyl)-4-nitro-8-oxa--10, also (2,3-a) dicyclo (3,2 for the 11-glyoxalidine, 1) suffering-3-alkene, English common name: cycloxaprid, chemical molecular formula C ₁₄H ₁₅ClN ₄O ₃Insect there are interior suction, stomach toxicity and action of contace poison, can be used for preventing and treating Homoptera, coleopteran pest on the crops, with no cross resistances such as Imidacloprid, Acetamiprid, thiophene worm piperazines, also effective to lepidoptera pest.This product using dosage is low, and is environmentally safe, and beneficial organism is not had harm or endangers minimum.The aphids of crops such as wheat, cotton, paddy rice, fruit tree, vegetables, plant hopper, aleyrodid, flea beetle, cotton bollworm, diamond-back moth, prodenia litura, armyworm etc. there is higher insecticidal activity.As a kind of novel anabasine insecticide, the pyridine of epoxy worm in use exists the use cost height, the risk that resistance risk increases gradually, efficient to homoptera pest, to the relatively poor defective of lepidoptera pest drug effect, and rationally use with dissimilar insecticides, for fully effectively promoting the pyridine of epoxy worm, prolong its service life and have important function.

Gamma cyhalothrin, English common name: Lambda-cyhalothrin, chemical name: 3-(2-chloro-3,3, the 3-trifluoro-propenyl)-2,2-dimethyl cyclopropane carboxylic acid alpha-cyano-3-phenoxybenzyl ester, insecticidal spectrum is wide, active higher, drug effect is rapid, sprays the back resistance of rainwater washing against, but long-term the use easily produces resistance to it, insect and evil mite to sucking mouth parts have certain preventive effect, but the using dosage of mite is increased 1-2 doubly than conventional amount used.Be applicable to the insect of peanut, soybean, cotton, fruit tree, vegetables.

Beta-cypermethrin, adopted name Beta cypermethrin, trade name: high guarantor, beta-cypermethrin, this product are non-internal-absorting but possess the insecticide of tagging with stomach poison function.Destroyed neural function by interacting with the insect sodium channel.Be used for public health and livestock breeding and prevent and treat various pests such as fly, cockroach, mosquito, flea, lice, bedbug, animal body epizoa such as tick, mite etc.

Cypermethrin, English name: Cypermethrin, other title: go out hundred can, Xing Mianbao, An Lvbao, Sai Bokai, struggle, chemical name: a-cyano group-(3-benzyloxy phenoxy base) (1RS)-suitable, trans-2,2-dimethyl-3-(2,2-dichloroethylene) cyclopropanecarboxylcompound, tool is tagged, stomach toxicity and the prevention effect of ingesting.Insecticidal spectrum is wide, and drug effect is rapid, and the ovum of some insect is also had a lethal effect, and the longevity of residure is more than 10 days.

Biphenthrin, English name bifenthrin; FMC-54800; Biphenthrin; Brigade; Capture; Talstar, the another name bifenthrin; Uranus; The spirit of worm mite; Bi Fenning; Chemical name: 2-methyl biphenyl-3-ylmethyl-(Z)-(1RS)-suitable-3-(2-chloro-3,3,3-three fluoro-1-acrylic)-2,2-dimethyl cyclopropane carboxylic acid ester, have tag, stomach poison function, do not inhale in not having, fumigation action, insecticidal action is rapider.

Betacyfluthrin, English name: beta-cyfluthrin, other title: protect, chemical name: cyano group-(4-fluoro-3-benzyloxy phenoxy base)-methyl-(2,2-dichloroethylene)-2,2-dimethyl cyclopropane carboxylic acid ester, have and tag and stomach poison function, insecticidal spectrum is wide, knocks down rapidly, lasting period is long, and plant has good drug resistance to it.

Ether chrysanthemum ester, english common name: ethofenprox, other titles MTI-500, trebon, have the characteristic of tagging with stomach toxicity, insecticidal spectrum is wide, insecticidal activity is high, knock down the characteristic that speed is fast, the lasting period is long, to aquatic organism safety, to crop safety, to natural enemies security.Be applicable to various pests such as control paddy rice, vegetables, cotton Lepidoptera, Semiptera, orthoptera, coleoptera, diptera and Isoptera.Especially the control efficiency to rice hoppers is remarkable, also is simultaneously that country forbids the appointed product of hypertoxic type agricultural chemicals after paddy rice is used.

Silafluofene, English name: silafluofen is a kind of siliceous novel organic insecticide, tool stomach toxicity and action of contace poison have characteristics such as activity is high, chemical property is stable.Termite is shown good repellent action.

Sumicidin: English name: fenvalerate, other title: come good fortune spirit, Belmark, Chinese and Western to kill the chrysanthemum ester, chemical name: (S)-alpha-cyano-3-phenoxy benzyl (S)-2-(4-chlorphenyl)-3 Methylbutanoic acid ester.To tag and stomach poison function, do not inhale and fumigation action in not having.Respond well to lepidopterous larvae.Insects such as Homoptera, orthoptera, Semiptera also there is effect preferably.

Fenpropathrin, English name: Fenpropathrin, Chinese: go out and sweep profit, chemical name: alpha-cyano-3-phenoxy benzyl-2,2,3,3-4-methyl cyclopropane carboxylic acid ester.Insecticidal spectrum is wide, and the longevity of residure is long, and it is its maximum characteristics that multiple tetranychid is had good result.

As a kind of novel anabasine insecticide, the pyridine of epoxy worm exists the use cost height after listing, and the risk that resistance risk increases gradually is efficient to homoptera pest, to the relatively poor defective of lepidoptera pest drug effect; The pyrethroid good disinsection effect, quick-acting is fast, but the lasting period is short, use year by year, resistance development is very fast, and the inventor is unexpected to be found the use that is mixed of the pyridine of epoxy worm and pyrethroid, have significant synergistic effect, can reduce use cost, slow down the effect of the generation of pest resistance.

Summary of the invention
