Background technique
Plant nematode is important one of phytopathy original, has concealment, more host's property, intractable and easily propagates
The features such as.Its population growth is rapid, prevention and treatment is difficult, causes sternly to China's grain, vegetables, industrial crops Isoquant and economic benefit
Ghost image is rung.Its main host plants crop includes soybean, potato, cotton, corn, tomato, carrot and beet etc..Nematode is endangered at present
Evil is on the rise, and constitutes a serious threat to production estimation.The whole world every year the crop failure as caused by eelworm harm up to 14%,
Cause economic loss 80,000,000,000~1,00000000000 dollar.Crop failure caused by China is encroached on because of nematode every year is up to 12%, and list is by line
Soybean annual output caused by worm loses between 5%~80%.Parasitic nematode destroys plant root, easily causes disease fungus after infecting
Infection aggravates the infringement of bacterium, fungi and virus, destroys plant growth, reduces crop yield and quality.
The fluorine thiophene worm sulfone mechanism of action is unique, has the function of compared with Organophosphorus and carbamate pesticides class nematicide different
Mechanism, the former has irreversible killing effect to nematode, and the latter can only play temporary control.The medicament has touching to nematode
The effect of killing, activity is reduced after nematode contact, and then is benumbed, and stops feeding, infection ability decline, egg production capacity after 1 h of exposure
It can reduce, institute's spawning and hatching rate decline, the larva hatched can not survive for a long time, finally irreversible to be killed.Fluorine thiophene worm
Sulfone not only has good control efficiency to various plants parasitic nematode, also has original killing living to serious root-knot nematode is endangered
Property.Studies have shown that the medicament can effectively prevent javanese root knot nematode, north south side root-knot nematode, thorn nematode, G.pallida,
The infringement of the pests on plants root system such as Meloidogyne chitwoodi, corn lesion nematode, peanut root-knot nematode.As with interior suction
Property non-fumigating nematicide, it can also be used to prevention and treatment harm agricultural and garden crop nematode.As non-stifling property nematicide
Application is simple, and easily by soil absorption, the time that other nematicides enter soil is about 5 days, and this product only needs 12 hours.It should
Medicament cannot maintain entire Growing season to the preventive effect of nematode, but energy cover crop is until established root system.
Thiodicarb be moderate toxicity amino-acid ester insecticides, to fish, bird safety, no slow poisoning, without carcinogenic, teratogenesis,
Mutagenesis, to crop safety.There is special efficacy to lepidoptera pest, and have ovicidal action, to cotten aphid, leafhopper, thrips and mite class
In vain, it can also be used to prevent and treat coleoptera, Diptera and Hymenoptera pest.Thiodicarb is mainly stomach poison function, almost without tagging
Effect has stronger selectivity, the residual period is very short in the soil without stifling and systemic action.Its mechanism of action is neural resistance
Hinder effect, i.e., hinders activating again for transmitter in nerve fibre to lead to pest by acetylcholine esterase inhibition activity
It is poisoned to death.Can ovicidal, can also kill larva and certain adults.Ovicidal activity is high, and show three aspects: 1. medical fluid connects
Unhatched ovum is touched, the hatching of ovum can be prevented or is made is i.e. dead before larvae development to 2 ages after hatching;2. being produced in 3 days after application
Ovum cannot hatch or cannot complete children phase development;It can effectively kill when 3. going out shell after egg hatching because chewing egg membrane and just incubate
Larva.Due to introducing thioether bond in the structure of thiodicarb, to using oxidative metabolism as the resistant insect product of detoxication mechanisms
System also has higher insecticidal activity.Desinsection is rapid, but the residual period is short, can only generally maintain 45 days.
An important component of the thiodicarb as pesticide has good inhibition to make crops Lepidoptera class pest
With residual life in the soil is short, environmentally friendly;And fluorine thiophene worm sulfone is as a kind of novel nematicide, it is suitable for thiodicarb
There is the good mechanism of action with the control of nematode of crop.Therefore the present invention passes through to thiodicarb and fluorine thiophene worm sulfone mixture formula
Further investigation, discovery is by thiodicarb and fluorine thiophene worm sulfone mixture, within a certain range of mixing ratios, to crops lepidoptera pest
And the prevention and treatment of nematode has apparent synergistic function, is decreased compared to single dose using environmental pollution, and the scope of application
Wider, the raising of healthy growth and yield for crops has obvious effect, after further research, complete the present invention.
