The composition is a mixture comprising compound (A) dinotefuran and compound (B) nitenpyram. The pesticide composition provided in the invention has high insecticidal efficiency and can effectively control insects on a plurality of crops like paddy rice, fruit trees and vegetables; the controlling effect of the composition is substantial superior to that of a single compound (A) or a single compound (B), and application dosage of each active substance is greatly reduced. The invention is not only of ecological significance, but also of important environmental protection significance.

Description

A kind of Pesticidal combination that contains MTI-446 and Nitenpyram

Technical field

The present invention relates to a kind of Pesticidal combination, relate to a kind of Synergistic insecticidal compositions that contains MTI-446 and Nitenpyram and uses thereof specifically with synergism performance.

Background technology

The English general of compound among the present invention (A) is called: English name: dinotefuran.The general MTI-446 by name of Chinese, the CAS accession number is: 165252-70-0.Chemical name is 1-methyl-2-nitro-3-(tetrahydrochysene-3-furfuryl) guanidine.MTI-446 is a nicotinic insecticide, and insecticidal spectrum is wide, has remarkable interior suction osmosis, and has promptly shown very high insecticidal activity at very low dosage.Can prevent and treat the paddy rice brown planthopper, white-backed planthopper, small brown rice planthopper, rice leafhopper, rice spider rafter stinkbug star stinkbug, green rice bug resembles, red palpus fleahopper, the negative mixed worm of rice, rice tube water snout moth's larva, striped rice borer, oryza chinensis class and control vegetables, the Phytophthira of fruit, the aleyrodid class, the a red-spotted lizard class, unaspis shield kuwana, the green stinkbug of Zhu, peach fruit borer, the tangerine lyonetid, the thin moth of tea, striped flea-beetle, the beans fly of diving, the cured a red-spotted lizard in angle, diamond-back moth, two secret notes are chrysomelid, tea golden thistle horse, onion thrips, the golden thistle horse, oranges and tangerines golden thistle horse, soybean pod gall-midge, the tomato Liriomyza.

Compound (A) is a third generation nicotinic insecticide.Also different at aspect of performance with nicotine.So people are referred to as " furans nicotine " at present.This medicament is fool proof to mammal, birds and aquatile, and crop is not had poisoning.

The English general nitenpyram by name of compound (B), the general Nitenpyram by name of Chinese, the CAS accession number is: 150824-47-8, 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, and the insect that conventional pesticides has been produced resistance has the better prevention effect.

MTI-446 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 MTI-446 and Nitenpyram.

Summary of the invention

The Pesticidal combination that the purpose of this invention is to provide MTI-446 and Nitenpyram, after suitable ratio mixing, by modern pesticidal preparations process technology, but be processed into conventional pesticide formulations such as missible oil, suspending agent, wetting powder, water dispersible granule dispersed oil suspending agent, 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) MTI-446 and compound (B) Nitenpyram.Weight ratio between compound in insecticides of the present invention (A) and the compound (B) generally is:

(A) MTI-446 is 1-100: 1-100 with (B) Nitenpyram.

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 passed through waterproof pulverization 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.

But the dispersed oil suspending agent is that the mixture of active component, thickener, preservative, wetting agent, dispersant, vegetable oil or methylated vegetable oil are made it evenly to disperse and suspend by waterproof pulverization, but obtains the dispersed oil suspending 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, 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.
