Description
Technical field
The invention belongs to agricultural insecticidal acaricide fields, and in particular to one kind is with second azoles mite nitrile and fenazaquin, chlopyrifos, connection
Benzene pyrethroids, Tolfenpyrad and avermectin are the composition pesticide of compounding, the agricultural evil being primarily adapted for use on fruits and vegetables, flowers etc.
Worm (mite) prevention and treatment.
Background technique
Second azoles mite nitrilation scientific name is known as (Z) -2- (4- tert-butyl-phenyl) -2- cyano -1- (1- ethyl -3- methylpyrazole -5-
Base) vinyl -2,2-Dimethylpropionic acid ester, it is the created compound of Shenyang Kechuang Chemical Co., Ltd., is with nitrile pyrrole mite ester
Lead compound, pyrazole ring and hydroxylic moiety carry out structural modification in nitrile pyrrole mite ester structure.Second azoles mite nitrile exists
High acaricidal activity is found to have within 2008, to honeybee, bird, fish, silkworm low toxicity.It is 30% suspending agent that it, which processes dosage form, for preventing and treating
Citrus red mite, apple tetranychus, cotton spider mites and vegetables tetranychid etc..
Fenazaquin chemical name: 4- spy-butyl phenethyl quinazoline, chemical formula: C20H22N20.Fenazaquin can be used as electronics biography
The compound that body replaces respiratory chain in mitochondria is passed, so that the binding site for occupying it with ubiquinone causes harmful mite to be poisoned；It has
Tag and stomach poison function, harmful mite drug effect is played rapidly, control period is long.It can be used for preventing and treating the apple on the crops such as orchard, vegetables
A variety of harmful mites such as Panonychus citri, tetranychus viennensis, panonychus citri, two-spotted spider mite；To panonychus ulmi, panonychus citri, leaves of Hawthorn
Various mite states such as summer egg, children mite and the adult mite of the harmful mites such as mite have very high activity.To two spot of apple for rising harm in recent years
The ovum and children, deutonymph of tetranychid also have very high drug effect, but relatively poor to adult mite effect.
Chlopyrifos (chlorine pyrazothion) chemical name: O, O- diethyl-O- (3,5,6- trichloro-2-pyridyl) thiophosphoric acid, point
Minor: C9H11Cl3NO3PS.Chlopyrifos is acetylcholinesterase inhibitor, belongs to thiophosphate insecticides, by inhibiting pest
The activity of acetylcholinesterase or cholinesterase ChE in nerves within the body and destroy normal nerve impulse conduction, draw
A series of poisoning symptoms: exaltation, spasm, paralysis, death are played, it is red to rice hoppers, the snout moth's larva of rice, pachydiplosis oryzae, citrus
Spider, coccid, Conopomorpha sinensis Bradley etc. have outstanding preventive effect.
Biphenthrin chemical name: (1R, S)-cis--(Z) -2,2- dimethyl -3- (fluoro- 1- propylene of the chloro- 3,3,3- tri- of 2-
Base) cyclopropane-carboxylic acid -2- methyl -3- phenyl benzyl ester, molecular formula: C46H44Cl2F6O4.Biphenthrin is a kind of quasi- deinsectization of synthesis
Pyrethroids class Insecticidal and acaricidal agent, by acting on pest nerve cell Na+Channel and interfere the normal nerve conduction system of pest,
Cause pest excited dead.Biphenthrin have tag, stomach poison function, no interior suction, fumigation action can prevent and treat each Lepidopterous children
Worm, aleyrodid, aphid, phytophagous tetranychid etc., insecticidal spectrum is wide, also has favorable effect to Panonychus citri, effect rapidly, does not move in the soil
Dynamic, safer to environment, the residual period is long.
Tolfenpyrad chemical name: the chloro- 3- ethyl -1- methyl-N- of 4- { [4- (4- methylphenoxy) phenyl]-methyl } -1H
Pyrazoles -5- carboxylic acid amides, chemical formula: C21H22ClN2O2.Tolfenpyrad is the novel pyrazole heterocyclic insecticidal/acaricidal agent of Japan's exploitation,
Its mechanism of action is that the electronics in block cell device mitochondrial metabolism system conveys system complex I, hinders electronics reception and registration
Hinder, prevent insect from providing and storing energy, referred to as Mitochondrial electron conveys complex Inhibitors (METI).Tolfenpyrad is killed
Worm spectrum is wide, have tag, stomach poison function, have special efficacy to lepidopterous larvae diamondback moth, Thysanoptera thrips.It is surveyed through toxicity
It is fixed, there is greater activity to diamondback moth and flower thrips.
Avermectin molecular formula: C48H72O14(B1a)、C47H70O14It (B1b), is a kind of living with desinsection, mite killing, nematicidal
Property ten hexa-atomic Macrocyclic lactone compounds, different from the general insecticide mechanism of action, avermectin is raw by interference pest nerve
Reason activity, stimulation discharge a large amount of γ-aminobutyric acids and inhibit the normal nerve conduction of pest.Pest contacted with avermectin after i.e.
There is inactive, not feeding, paralysis symptom, dead after 2~4 days, lethal effect is slower, is unable to ovicidal.Avermectin is to catching
Though feeding habits insect and insect parasite have direct action of contace poison, because plant surface residual is few, therefore to the damage very little of beneficial insect.Ah
Dimension rhzomorph will not be moved in soil by adsorption by soil, and be decomposed by the microorganisms, thus in the environment without cumulative function, Ke Yizuo
For a component part of integrated control.
In agricultural production process, pest control guarantees that the method for high crop yield stable yields is varied, but at present
Chemical prevention is still most effective means.Since there are nonstandard use, especially single composition desinsections for chemical pesticide
Agent is used in conjunction for a long time, many drawbacks occurs, in food pesticide residue, environment pesticide residue, pest resistance increase, prevention and treatment dosage
A series of problems, such as rising, how Ke Xue the agriculture chemical compounding or compounded product high using pesticide, promotional technique content is each
Pesticide insider should close focus deeply concerned.
The compounding of the exploitation pesticidal preparations of science can not only increase the preventive effect to target pest, even more raising pesticides application
Efficiency, the effective road for implementing zero growth rate strategy, reducing residual, reduce environmental pollution, delaying pest resistance to insecticide.Pesticide compositional
It is the general orientation of current pesticide developing, however most of agriculture chemical compounding is addition, some even antagonisms have and increase
The only minority of effect effect.The present inventor by a large amount of indoor and field trial exploration discovery second azoles mite nitrile and fenazaquin,
Chlopyrifos, Biphenthrin, Tolfenpyrad and it is abamectin compounded after there is apparent synergistic effect, and expand desinsection
Spectrum, improves the output value and plant protection efficiency significantly.About second azoles mite nitrile and fenazaquin, chlopyrifos, Biphenthrin, Tolfenpyrad,
The compounding agent or patent of avermectin etc. there are no open report.
Summary of the invention
The present invention discloses a kind of efficient, less toxic, inexpensive, quick-acting is good, the lasting period is long desinsection containing second azoles mite nitrile
Mite killing compounding agent is expected to take on key player in integrated pest management.
The present inventor has made intensive studies second azoles mite nitrile compounding, in a large amount of indoor joint toxicity measuring and field medicine
On the basis of effect test, discovery second azoles mite nitrile and fenazaquin, chlopyrifos, Biphenthrin, Tolfenpyrad, avermectin are certain
