Abstract
The invention belongs to the field of pesticides, and particularly discloses insecticidal composition comprising flonicamid and cycloxaprid. The weight ratio of the flonicamid to the cycloxaprid in the composition is 50:1-1:10, the total weight percentage of active ingredients is 3%-80%, and the rest is adjuvant ingredients permissible and acceptable in pesticides; the flonicamid and the cycloxaprid in the ratio have the obvious synergistic effect after being compounded, have obvious effects on controlling aphids in vegetables and fruit trees, rice planthoppers and the like, have very high safety for humans, livestock and environments, and can have the good killing effect on pests resisting to other insecticides after the two ingredients are compounded.
Description
Technical field
The invention belongs to technical field of pesticide, relate to pesticide combination technology, particularly a kind of Pesticidal combination.
Background technology
Flonicamid, chemical name: N-cyanogen methyl-4-(trifluoromethyl) vitamin PP; Molecular formula: C

3, structural formula is:
Cycloxaprid is a kind of novel neonicotinoid insecticide, belong to the environment friendly agricultural of high-efficiency low-toxicity, be mainly used to prevent and treat sucking pest, according to effect experiment, cycloxaprid is all efficient to Brown Planthopper, white-backed planthopper, small brown rice planthopper, also there is good preventive effect to cabbage aphid and Cucumber blight, have to rice leaf roller anti-effect of holding concurrently preferably, Imidacloprid is significantly higher than to cotton field Bemisia tabaci activity.In addition, its honeybee toxicity also significantly reduces, and efficient to Imidacloprid resistant insect.
Have in prior art and be used alone flonicamid or cycloxaprid, but yet there are no flonicamid and the composite relevant report of cycloxaprid, the effect after also not having corresponding technology to enlighten to determine both composite how.
Summary of the invention
The present invention is directed to prior art Problems existing, provide the Pesticidal combination of a kind of flonicamid and cycloxaprid, in said composition, flonicamid and cycloxaprid weight ratio are 50: 1 ~ 1:10, the percentage by weight of active component is 3 ~ 80%, and all the other are allow in agricultural chemicals to use and acceptable auxiliary element; Adopt the flonicamid of proportioning of the present invention and cycloxaprid composite after there is obvious synergistic effect, can be applicable to prevent and treat aphid in fruit and vegetables and rice hoppers etc. and have obvious effect, and two kinds of components have high safety for people, animal, environment, these two kinds of components are composite, and the insect that can have a resistance for other insecticides has good insect killing effect.
Concrete technical scheme of the present invention is:
The Pesticidal combination of a kind of flonicamid and cycloxaprid, its principle active component is flonicamid and cycloxaprid, wherein flonicamid and cycloxaprid weight ratio are 50: 1 ~ 1:10, the percentage by weight of active component is 3 ~ 80%, and all the other are allow in agricultural chemicals to use and acceptable auxiliary element.
Further, flonicamid and cycloxaprid weight ratio are 15: 1 ~ 1:1; The percentage by weight of active component is 5-50%;
Can be any one in missible oil, wetting powder, suspending agent, granule, microemulsion, aqueous emulsion, water-dispersible granules according to the formulation of aforementioned proportion Pesticidal combination of the present invention, corresponding auxiliary element of only need arranging in pairs or groups.Wherein alternative auxiliary element comprises acceptable organic solvent, emulsifier, surfactant, inert filler etc.; Wherein acceptable organic solvent comprises, fat hydrocarbon organic solvent, arene organic solvent, plant oil solvent, alcohol organic solvent, lipid organic solvent or organic solvent of ketone etc.; Adoptable surfactant has anionic surfactant and nonionic surface active agent.Other auxiliary element also comprises xanthans, the thickeners such as sodium carboxymethyl starch, the antifreezing agents such as ethylene glycol, glycerine, urea; The fillers such as kaolin, bentonite, attapulgite, charcoal acid calcium, and the acceptable stabilizing agent of other pesticidal preparations, safener, colouring agent etc.
This Pesticidal combination can have good effect on the aphid on the fruit trees such as vegetables and apple such as control cucumber.
The anti-principle active component flonicamid effect used that eliminates aphis reduces gradually at present, and various aphid is more and more stronger for the resistance of medicine.Therefore, on the basis of the original single dose of flonicamid, carry out composite with this anabasine of cycloxaprid composition, improve the preventive effect for aphid.
Flonicamid novel low-toxicity picolinamide class insect growth regulator, IGR insecticides in the present invention, flonicamid is tagged and stomach poison function except having, and also has good never poison and quick Antifeedant Effects.The suckings pest such as aphid take food and suck with after the water of flonicamid, can be stoped rapidly and inhale juice, not have excreta to occur within an hour completely, finally dead because of hungry.Cycloxaprid is a kind of novel neonicotinoid insecticide, belongs to the environment friendly agricultural of high-efficiency low-toxicity, is mainly used to control pierce-suck type implication insect.The nicotinic acetylcholine esterase acceptor of Selective Control insect nerve system, blocks the conduction of insect CNS.
Compared with prior art, the cycloxaprid mechanism of action in the present invention is different with other anabasine insecticides: the electro physiology that cycloxaprid carries out respectively and isotopic label replace experiment and show that cycloxaprid can be combined with nAChR high-affinity, can suppress the reaction of Agonists Acetylcholine simultaneously; Agonism is not had to Nl α 1/ beta 2 receptor of U.S.'s blattaria nAChR and Expressed in Xenopus Oocytes; These experiments show that cycloxaprid is the antagonist of nAChR (nAChRs), because herein is provided the composite form Pesticidal combination of a kind of brand-new flonicamid.
In sum, Pesticidal combination Pesticidal combination provided by the invention, there is insecticidal spectrum wide, efficiently, low toxicity, low-residual, synergistic effect significantly and reduce the features such as use cost, can effectively kill except fruit tree, aphid on vegetables, to plant growth safety when not only using, also can delay or overcome the drug-fast generation of aphid, be conducive to agricultural synthesis to administer, said composition preventive effect is significantly higher than the preventive effect of alone flonicamid and cycloxaprid, and the application dosage of each bioactivator can be reduced, reduce the adverse effect to ecotope, it applies huge Social benefit and economic benefit.
