On the basis of preserving the original preventing effect, the insecticide composition has the synergistic effect; the insecticide composition enlarges the insecticidal spectrum and can delay resistance generation to the insecticide composition by insects. The price of cycloxaprid is much higher than that of dimehypo, dimehypo and a small amount of cycloxaprid are compounded, the insecticide effect of using the insecticide composition is obviously higher than that of singly using cycloxaprid or dimehypo, the production cost is reduced, and economic loads of peasants are relieved.
Description
Technical field
The invention belongs to pesticide field is and in particular to a kind of Pesticidal combination containing cycloxaprid and dimehypo simultaneously.
Background technology
In recent years, the science that carried out with two or more insecticide compounds, in order to expand insecticidal spectrum or to improve anti-
Control effect, find broad application.As emamectin-benzoate and dimehypo, phoxim and dimehypo, chlopyrifos with
The agricultural chemicals that dimehypo, Methomyl and dimehypo etc. compound is applied in agricultural production.
Paddy rice is China's staple food crop, and the snout moth's larva of rice and planthopper are the primary pests in Rice Cropping, wherein again
Endangered for very with rice leaf roller, striped rice borer and brown paddy plant hopper, white backed planthopper.
Rice leaf roller (Cnaphalocrocis medinalis Guenee) be China paddy rice producing region primary pest it
One, it is distributed widely in each rice region.It is caused harm paddy rice with larva, sews leaf and becomes vertical bud, hides and wherein take food epicuticle and mesophyll, only stay
White lower epidermis.Seedling stage aggrieved impact paddy rice normal growth, in addition withered；Tillering stage is aggrieved to the jointing stage, and tiller reduces, plant
Shorten, breeding time postpones；Particularly ear after booting killed to full heading time sword-like leave, impact is blossomed and beared fruit, Empty grain rate improves, thousand
Decline again.General underproduction 2-3 becomes, weight reach 5 one-tenth more than, big when occurring rice leaf a piece of withered white, or even No kernels or seeds are gathered, as in a year of scarcity.
Rice leaf roller is a kind of migratory pest, and from north, southern year occurred for 1～11 generation；Rice leaf roller was from 2003
Since China occurs national breaking out, maintain higher level always, year, occurring area was more than 300,000,000 mu times.Show as：Peak
Secondary increase, master moves peak to be increased；Occurrence scope expands, and area increases；Field generations are overlapping serious, and harm time is long；The south of the River, the Changjiang river
Middle and lower reaches, southwest-northeast portion are retransmitted year after year.
Rice hoppers (rice planthopper) belong to Homoptera Delphacidae.Hazard rice mainly have brown paddy plant hopper, white
Backward flight lice and three kinds of small brown rice planthopper.Harm is heavier to be brown paddy plant hopper and white backed planthopper, early rice early stage based on white backed planthopper, the later stage with
Based on brown paddy plant hopper；Middle late rice is based on brown paddy plant hopper.
Planthopper is caused harm to paddy rice, except directly thorn inhales juice, makes growth retardation, and when serious, rice clump is agglomerating withered, or even
The dead stalk lodging of full field is outer, and spawning also can stab plant, destroys conducting tissue, hinders nutriment transport transmitted virus disease.
At present, the compounded pesticides kind of the preventing and treating snout moth's larva of rice and plant hopper is a lot, mainly has to planthopper prevention effect relatively
Good imidacloprid and the formula preventing and treating the pesticide compositionals such as the preferable Cupric sulfate of snout moth's larva effect, Hostathion.
However, because the resistance of imidacloprid increases quickly, with the accumulation of use time, prevention effect constantly declines, mu
Dosage dramatically increases, and not only increases agriculture production cost, and has increased the impact to environment.
Particularly imidacloprid not only have resistance, but also serious to the bee colony poisoning propagating pollen in nature, therefore
The bee colony decreasing in nature propagates plant pollen, has blocked the breeding chain of plant in nature, various to natural, ecological
Property causes seriously to threaten.Therefore can imidacloprid be continuing with, and create sharp in agricultural management department and pesticide producing department
Strong arguement.EFSA (EFSA) issues a public proclamation title, will reset the nicotinoids agricultural chemicals such as imidacloprid, Acetamiprid
Toxicity criterion.Canadian pest control management organization (PMRA) will be carried out to the environmental risk of nicotinic insecticide imidacloprid
Again evaluate.Environmental Protection Agency began to disclosure and carries out review to nicotinic insecticide imidacloprid early in 2009.Brazilian environmental protection
Administration (IBAMA) also will reappraise four nicotinic insecticide imidacloprids.
Cycloxaprid (cycloxaprid), is a kind of bionical insecticide of new anabasine, belongs to efficient, low toxicity
Environment friendly agricultural, is mainly used to prevent and treat pierce-suck type implication insect.According to report, cycloxaprid is to Brown Planthopper, white backed planthopper, ash
Plant hopper is all efficient, also has good preventive effect to cabbage aphid and Cucumber blight, has preferably simultaneous anti-effect to rice leaf roller, to cotton
Field Bemisia tabaci activity is significantly higher than imidacloprid.In addition, cycloxaprid is very low to honeybee toxicity, overcome the bionical desinsection of anabasine
The critical defect of agent, and to imidacloprid resistant insect (imidacloprid-resistant pest) efficiently.
Dimehypo (bisultap), the bionical insecticide of nereistoxin, is a kind of never poison, and insect contacts and takes food medicament
Show afterwards ability that is blunt, slow in action, losing infringement crop, stop developing, polypide softens, paralysis, until dead.Desinsection
Double have very strong systemic action, can be absorbed by the leaf of crop, root etc. and conduct.Dimehypo belongs to biomimetic type agricultural chemicals, to environmental organism
And pest natural enemy little, the non-resistant of impact, no residual hazard, free from environmental pollution, it is the comparatively ideal medicament of comprehensive regulation insect pest.
Dimehypo has stronger tagging and stomach poison function to insect, and has certain fumigation action concurrently.Have very strong interior
Suction acts on, and can be absorbed by the leaf of crop, stem, root etc. and conduct.It is applied to the crops such as paddy rice, vegetables, fruit tree, cotton and wheat.
Particularly there is special efficacy to the snout moth's larva of rice, become the conventional medicament of snout moth's larva of rice preventing and treating.
Cycloxaprid and two kinds of medicaments of dimehypo respectively have pluses and minuses when being used alone, and such as dimehypo is to lepidoptera pest such as two
Change snout moth's larva, yellow rice borer, rice leaf roller effect are good, poor to the perverse suction mouthpart insect effect such as planthopper, and cycloxaprid is inhaled to thorn
Formula mouthpart insect such as planthopper etc. shows excellent prevention effect, but poor to lepidoptera pest prevention effect.
Content of the invention
