Description

A kind of Pesticidal combination that contains thiophene insect amide and pyrethroid insecticides
Technical field
The present invention relates to a kind of Pesticidal combination, be specifically related to a kind of Pesticidal combination that contains thiophene insect amide and pyrethroid insecticides, pyrethroid insecticides is ether chrysanthemum ester, silafluofene, tefluthrin, gamma cyhalothrin, Biphenthrin, beta-cypermethrin or betacyfluthrin, belongs to technical field of compounded pesticide.
Background technology
The thiophene insect amide, test code number JS9117, chemical name is 3-bromo-N-{4-chloro-2-methyl-6-[2-(5-amino-1,3, the 4-thiadiazoles)] phenyl-1-(3-chloropyridine-2-yl)-1H-pyrazoles-5-formamide, be the novel neighboring Heterocyclic formanilide compound that the Jiangsu pesticide research is developed, high-efficiency broad spectrum, harmful insect is had good control efficiency, and this compound can have efficiently with the insecticide in fields such as preparation agricultural, gardening, low toxicity, eco-friendly advantage.Result of the test shows the specific activity other products height to target pest, and can cause some lepidopterous insects mating process disorder, studies have shown that it can reduce the spawning rate of multiple noctuidae pests, because its lasting effect is good and the biological property of resistance of rainwater washing against, these characteristics are actually permeability, conductivity, chemical stability, high insecticidal activity and cause insect to stop to get the comprehensive embodiment of effects such as food immediately.Therefore determined it to have longer and more stable and to the protective effect of crop at other insecticide of usefulness than the present overwhelming majority.But it exists quick-acting general, the high defective of single agent use cost.
Ether chrysanthemum ester, other titles of english common name ethofenprox MTI-500, trebon has 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 on control paddy rice, vegetables, the cotton, various pests such as Lepidoptera, Semiptera, orthoptera, coleoptera, diptera and Isoptera are had efficiently.Especially the control efficiency to rice hoppers is remarkable, also is simultaneously that country forbids the appointed product of hypertoxic type agricultural chemicals after using on the paddy rice.
Tefluthrin, Chinese: 2,3,5,6-tetrafluoro-4-methyl-benzyl (Z)-(1RS, 3RS)-3-(2-chloro-2,3,3-trifluoropropyl-1-thiazolinyl)-2,2-dimethyl cyclopropane carboxylic acid ester, English name: 2,3,5,6-Tetrafluoro-4-methylbenzyl (Z)-(1RS, 3RS)-3-(2-chloro-3,3,3-trifluoro-1-propenyl-2,2-dimethylcyclopropanecarboxylate; Tefluthrin, this product belongs to pyrethroid insecticides, is soil insecticide, can prevent and treat coleoptera and Lepidoptera and some Diptera pest of perching in soil well.Can prevent and treat soil pests such as pumpkin 12 star first, wireworms, flea beetle, chafer, Atomaria linearis, cutworm, corn borer, Oscinella frit with 12～150g(ai.)/ha.Granule and liquor are used for corn and beet.Application method is flexible, and available conventional equipment spreads granula, table soil and ditch spread or seed treatment.
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.
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.
Biphenthrin, English name bifenthrin; FMC-54800; Biphenthrin; Brigade; Capture; Talstar, the another name bifenthrin; Uranus; The spirit of worm mite; Bi Fenning; 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.
Beta-cypermethrin, adopted name Beta cypermethrin, the high guarantor of trade name, beta-cypermethrin, this product is non-internal-absorting but possesses 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.
Betacyfluthrin, adopted name: betacyfluthrin (beta-cyfluthrin), other title: protect, chemical name: cyano group-(4-fluoro-3-benzyloxy phenoxy base)-methyl-(2, the 2-dichloroethylene)-2,2-dimethyl cyclopropane carboxylic acid ester, betacyfluthrin are a kind of synthetic pyrethroid insecticideses, have and tag and stomach poison function, insecticidal spectrum is wide, knock down rapidly, the lasting period is long, and plant has good drug resistance to it.
At present, the pesticidal preparations that with the thiophene insect amide is effective ingredient is based on 20% thiophene insect amide suspending agent, and in actual use, lasting effect is long, but quick-acting is general, the use cost height; 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 thiophene insect amide and pyrethroid, have significant synergistic effect, can reduce use cost, slow down the effect of the generation of pest resistance.
Summary of the invention
The object of the present invention is to provide a kind of component reasonable, significantly synergy, good disinsection effect, drug cost is low, the thiophene insect amide that is difficult for developing immunity to drugs and the Pesticidal combination of pyrethroid insecticides.
In order to overcome the defective of existing unitary agent, technical scheme of the present invention is to solve like this:
