Description

It is a kind of to contain the composition pesticide for killing aphid element and pymetrozine
Technical field
The invention belongs to synergetic pesticide composition field, specifically provide and a kind of containing active ingredient pymetrozine and kill aphid element Synergetic pesticide composition.
Background technology
Pymetrozine (Pymetrozine) belongs to pyridines or Triazinone insecticide, is brand-new non-killing livestock property insecticide, Developed earliest by Ciba-Geigy company of Switzerland in 1988, the product shows excellent to the sucking pest of various crop Prevention effect, have the characteristics that efficiently, low toxicity, high selectivity, to Environment Ecological Safe, its preparation can be used for preventing and treating largely Homoptera pest, especially aphid section, Aleyrodidae, Cicadellidae etc..Suitable for vegetables, rice, melon and fruit and a variety of field crops.
It is light gray streptomycete Hangzhou mutation (Streptomyces griseolus var.hangzhouensis to kill aphid element N.var.YANet FANG 1978) caused by antiinsect antibiotic, there is stronger contact toxicity to insects such as planthopper, mite class, Efficiently, low toxicity, low-residual, can effectively prevent and treat Bemisia tabaci and planthopper.
Planthopper, Piroplasmea Homoptera (Homoptera) Delphacidae (Delphacidae) insect, popular name fire midge worm.Inhaled with piercing Plant juice is caused harm the crops such as rice.Frequent species has brown paddy plant hopper (Nilaparvata lugens), white backed planthopper (Sogatella furcifera) and small brown rice planthopper (Laodelphax striatellus).
Bemisia tabaci [Bemisia tabaci (Gennadius)] is a kind of global insect.It is primary in the torrid zone and Asia heat Zone, since the 1980s, with worldwide trade contacts, Bemisia tabaci is by flowers and other industrial crops Nursery stock is spread rapidly, in wide-scale distribution all over the world and population outbreak, as the U.S., India, Pakistan, the Sudan and with Important pests in the National agricultural production such as color row.Bemisia tabaci (Bemisia tabaci) is to endanger the invader of maximum in the world One of kind, crushing harm is caused to many crops of China and other multiple countries and regions in phagocytic process.One The research announcement that item is completed in China and Australia, the mating behavior of this insect can help its to invade indigenous Bemisia tabaci Manor, the little indigenous Bemisia tabaci of harmfulness is become extinct and substituted.
The single use of agricultural chemicals can bring resistance risk, and agriculture chemical compounding is the effective way for solving resistance problem.
Develop new product bactericide is expensive, the cycle is grown, and by contrast, exploitation is efficient, less toxic, low-residual with research Compounding have with mixture invest small, lead time it is short and by attention both domestic and external, it is numerous and confused to increase development dynamics.
Pymetrozine has no report with the combination for killing aphid element.
The content of the invention
It is an object of the present invention to provide it is a kind of containing pymetrozine and kill aphid element composition pesticide, for prevent and treat tomato Bemisia tabaci, Planthopper.
The present invention is achieved through the following technical solutions:
It is a kind of containing kill aphid element composition pesticide, containing active ingredient pymetrozine and kill aphid element, pymetrozine and kill aphid element Mass fraction ratio is 90:1~9:1, it is preferably in a proportion of 60:1~201, further preferred ratio is 39:1~29:1, more enter one Step is preferably in a proportion of 39:1 and 29:1.
The described composition pesticide plain with aphid is killed containing pymetrozine, containing active ingredient pymetrozine and aphid element is killed, is also contained There is insecticides adjuvant, in order to be processed into insecticides adjuvant, wherein pymetrozine and kill the gross weight percentage composition of aphid element in the composition For 0.1%~50%, remaining is insecticides adjuvant.
The described composition pesticide plain with aphid is killed containing pymetrozine, can be processed into aqueous suspension agent, aqueous emulsion, micro emulsion Agent.
The aqueous suspension agent formulation weight percent forms:Pymetrozine 0.1~45%, aphid element 0.1~5% is killed, point Powder 0.1~13%, wetting agent 0.1~12%, thickener 0.1~1%, antifreezing agent 0.1~2%, deionized water carrier are supplied To 100%;Specifically production stage is:Active ingredient and other auxiliary agents are mixed, disperses through high speed shear, are sanded in sand mill Afterwards, high dispersive, stable suspension system are formed in water-medium, the aqueous suspension agent of corresponding weight percentage is made.
The aqueous emulsion agent weight percent forms:Pymetrozine 0.1~45%, aphid element 0.1~5% is killed, emulsified Agent 0.1~15%, solvent 0.1~22%, dispersant 0.1~6%, stabilizer 0.1~1%, antifreezing agent 0.1~6%, defoamer 0.1~1%, deionized water carrier complements to 100%;Specifically production stage is:By above-mentioned active ingredient, solvent, emulsifying agent, point Powder and stabilizer are mixed to form oil phase, and antifreezing agent dissolves in water forms aqueous phase, and slowly oil phase is added under cutter effect Enter in aqueous phase, and continue shearing 30 minutes, that is, the aqueous emulsion is made.
The micro-emulsion form weight percent forms:Pymetrozine 0.1~45%, kill aphid element 0.1~5%, solvent 0.2-16%, stabilizer 0.1~8%, emulsifying agent 0.1~9%, penetrates into 0.1~3%, antifreezing agent 0.1~5%, deionized water Carrier complements to 100%;Specifically production stage is:Active ingredient is completely dissolved with solvent, then adds emulsifying agent, stably Agent, bleeding agent, antifreezing agent are well mixed, and are eventually adding deionized water, after being sufficiently stirred, you can the microemulsion is made.
Described auxiliary component is solvent, emulsifying agent, wetting agent, dispersant, stabilizer, antifreezing agent, thickener, bonding Agent, disintegrant, defoamer, bleeding agent, preservative, all it is to commonly use in pesticidal preparations or allow the composition used, has no special limit Fixed, specific composition and dosage are according to recipe requirements by simply testing determination.
Described is applied to preventing and treating planthopper, tomato Bemisia tabaci containing the composition pesticide for killing aphid element.
Compared with prior art, the advantage of the invention is that:
1st, pymetrozine and kill aphid element compounded in the range of certain proportion to tomato Bemisia tabaci, Brown Planthopper have collaboration increase Effect acts on.
2nd, pymetrozine and aphid element two kinds of active ingredients compounding is killed, reduces Pesticide use amount, reduce use cost, mitigate Pollution to environment, the drug-fast service life for producing, adding agricultural chemicals of pest and disease damage is delayed.
Embodiment
According to the abundant methods of Sun Yun, the synergy of pharmacy mix is evaluated according to co-toxicity coefficient (CTC), i.e. CTC≤80 are association Same antagonism, 80 < CTC < 120 are joint action of antagonism, and CTC >=120 are synergistic function.Survey toxicity index (ATI)=(LC of standard agent50The LC of/reagent agent50)×100;The toxicity index of theoretical toxicity index TTI=A medicaments × In mixture in toxicity index × mixture of the percentage composition+B medicaments of A medicaments B medicaments percentage composition;Co-toxicity coefficient (CTC)= [mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI)] × 100;;
