Abstract

The invention belongs to a synergistic insecticidal composition, a preparation method and application thereof. The composition is a mixture consisting of pymetrozine serving as a compound (A) and nitenpyram serving as a compound (B). The insecticidal composition is high in insecticidal efficiency, can effectively prevent and control pests on rice, fruit trees, vegetables and other various crops, has the control effect significantly higher than the control effect of separately using the compound (A) or the compound (B), and greatly reduces the application dosage of each active substance. The invention not only has ecological significance, but also has important significance for environmental protection.

Description

A kind of Pesticidal combination that contains pyrrole aphid ketone and Nitenpyram

Technical field

The present invention relates to a kind of Pesticidal combination, relate to a kind of Synergistic insecticidal compositions that contains pyrrole aphid ketone and Nitenpyram and uses thereof specifically with synergism performance.

Background technology

The pyrrole aphid ketone general by name of compound among the present invention (A), chemical name is 4,5-dihydro-6-methyl-4-(3-pyridine methylene amino)-1,2,4-3 (2H)-ketone.Belong to non-lethal novel pesticide, can be used for preventing and treating most of homoptera pest, especially aphid section, Aleyrodidae, Cicadellidae and Delphacidae insect, be applicable to vegetables, ornamental plants, hop, deciduous fruit tree, oranges and tangerines, paddy rice, cotton and multiple field crop, can also control important aphids all on the potato to reach the generation of control potato virus disease.

Compound (A) has very strong interior absorption, can be absorbed by crop well, spreads to each position of crop by interior suction conduction.Its mode of action uniqueness is not directly knocked down activity to insect, and in a single day insect touches this medicament, just can stop up the insect lancet at once, make it stop to get food, and this process be irreversible, in because of several days times before stopping to get food death, handle insect and may show very normally.Exactly because the mechanism of action of pyrrole aphid ketone uniqueness, make it and produced in the past in a large amount of medicaments that use do not have cross resistance, and have the selectivity of height, mammal, birds, fishes and shrimps, honeybee, non-target arthropods etc. are all had good safety.Investigation shows, even organic phosphor and carbamate insecticide have been produced resistance, pyrrole aphid ketone to sucking pest particularly aphid, trialeurodes vaporariorum, rice leafhopper still have unique control efficiency, can be used for the control of multiple resistant strain insect.

The Nitenpyram general by name of compound (B), chemical name are that (E)-N-(6-chloro-3-picolyl)-N-ethyl-N '-methyl-2-nitro ethylene diamine is a kind of insecticide.This insecticide can be widely used in the various rice fulgorids of control, aphid, thrips, trialeurodes vaporariorum, Bemisia tabaci, leafhopper, thrips etc. on paddy rice, wheat, cotton, cucumber, eggplant, radish, tomato, potato, muskmelon, watermelon, peach, apple, pears, oranges and tangerines, grape, the tea, the insect that conventional pesticides has been produced resistance has the better prevention effect, is the first-class various pests of the last word of nicotinoids agricultural chemicals development so far.

Pyrrole aphid ketone and Nitenpyram are mixed with suitable ratio, not only can improve drug effect, reduce dosage, save Financial cost, reduce medicament residual in environment.Can also delay simultaneously the generation of pest resistance to insecticide, prolong the service life of medicament.Also do not find at present the report of using with of pyrrole aphid ketone and Nitenpyram.

Summary of the invention

The Pesticidal combination that the purpose of this invention is to provide pyrrole aphid ketone and Nitenpyram, after suitable ratio mixing, by modern pesticidal preparations process technology, be processed into conventional pesticide formulations such as missible oil, suspending agent, wetting powder, water dispersible granule, be used to prevent and treat the insect on the various crop such as paddy rice, fruit tree, vegetables.

Pesticidal combination provided by the invention is characterized in that comprising compound (A) pyrrole aphid ketone and compound (B) Nitenpyram.Weight ratio between compound in insecticides of the present invention (A) and the compound (B) generally is:

(A) pyrrole aphid ketone is 1-50 with (B) Nitenpyram: 1.

Pesticidal combination provided by the present invention can effectively be prevented and treated the insect on the various crop such as paddy rice, fruit tree, vegetables.Preventive effect is significantly higher than the preventive effect of compound alone (A) or compound (B), and can reduce the application dosage of each bioactivator.

The present invention is used to prevent and treat the insect on the various crop such as paddy rice, fruit tree, vegetables.Do spraying at the insect pest initial stage of origination and handle, the method for processing can be by adding good composition or before use that the different activities component is mixed and handled.

Adoptable surfactant has anion surfactant and non-ionic surface active agent.It comprises alkylsurfuric acid salt, alkyl sulfonic acid alkali metal salt and amido, dialkyl group succinate sodium sulfonate salt, alkylphenol polyoxyethylene formaldehyde condensation products sulfonate, sodium sulfate of polyethenoxy ether of fatty alcohol alkyl polyoxyethylene ether sulfate, alkylnaphthalene sulfonate, fatty acid or fatty acid ester sulphate, alkylphenol polyoxyethylene and fatty alcohol-polyoxyethylene ether etc.That can give an example has farming newborn 2000 series, lignosulfonates, NNO, a dispersing agent MF etc.

Missible oil be with each solubilization of active ingredient in solvent toluene or dimethylbenzene or methyl alcohol, add the allotment of suitable emulsifier and form.Can optionally add auxiliary agents such as suitable stabilizing agent, bleeding agent.The content of active principle is 1-90% (weight) in the missible oil

Suspending agent is that the mixture of each active component, emulsifier, wetting agent, dispersant etc. are pulverized by wet grinding together, make it evenly to disperse and suspend, can suitably add simultaneously suitable auxiliary agent such as thickener, antifreezing agent, stabilizing agent, bleeding agent as required, active principle content is 1-80% (weight).

Wetting powder is with the mixture of active component, inert carrier and filler and one or more wetting agents, dispersant, bleeding agent, obtains wetting powder by ultramicro grinding, and active principle content is 1-90% (weight) in the wetting powder.

Water dispersible granule is with the mixture of active component, inert carrier and filler and one or more wetting agents, dispersant, bleeding agent, after ultramicro grinding, carries out granulation by fluid bed or fashion of extrusion after adding a certain amount of binding agent.

Pesticidal combination provided by the invention has following beneficial effect: the insecticide efficiency height, can effectively prevent and treat the insect on the various crop such as paddy rice, wheat, fruit tree, vegetables.Preventive effect is significantly higher than the preventive effect of compound alone (A) or compound alone (B), and has significantly reduced the application dosage of every kind of active substance, and the present invention simultaneously can replace the insecticide pesticide kind of high poison, high residue.The present invention not only has ecological significance, also has important environment protection significance simultaneously.
