Description

Rynaxypyr and hexaflumuron insecticidal composition

Technical field:

The present invention relates to have the Pesticidal combination of synergism performance.

Background technology

The Rynaxypyr general by name of compound (A), chemical name are 3-bromo-N-[4-chloro-2-methyl-6-[(methyl-carbamoyl) benzene]-1-(3-chloropyridine-2-yl)-1-hydrogen-pyridine-5-formamide is a kind of insecticide.This insecticide can be used for preventing and treating mythimna separata (subtropics mythimna separata, the meadow mythimna separata, yellow bar mythimna separata, western yellow bar mythimna separata), cotton bollworm, the moth-eaten moth of tomato, the tomato Grapholita spp, hawkmoth, garden webworm, potato tuberworm, diamond-back moth, cabbage looper, noctuid, beet armyworm, codling moth, peach fruit borer, oriental fruit moth, rose slanted bar leaf roller, the apple olethreutid, spot curtain leaf miner, apple leaf miner, rice-stem borer, paddy stem borer, pink rice borer, rice leaf roller, cabbage caterpillar, European corn borer, Asiatic corn borer, melon worm, melon thin,tough silk snout moth's larva, the wild snout moth's larva of melon, various pests such as oriental tobacco budworm.Fluorine bell urea is novel acylureas insecticides; except that having other acyl group ureas desinsection characteristics; insecticidal spectrum is wider, and the insect to genus heliothis has special efficacy especially, and is respond well to noctuidae pests such as gypsymoth, tent caterpillar, dysychira abietis, beet armyworm, the real noctuids of paddy.The power of knocking down is strong, and insecticidal effect is rapider than other acylureas, has higher contact ovicidal activity.Rynaxypyr and using with of fluorine bell urea are not appeared in the newspapers, so the immixture of Rynaxypyr and fluorine bell urea is unforeseen.

Summary of the invention

Pesticidal combination provided by the invention is characterized in that comprising compound (A) Rynaxypyr and (B) fluorine bell urea.

Compound (A):

Rynaxypyr: benzene 3-bromo-N-[4-chloro-2-methyl-6-[(methyl-carbamoyl)]-1-(3-chloropyridine-2-yl)-1-hydrogen-pyridine-5-formamide

Structural formula is:

Compound (B):

Fluorine bell urea: N-[(3,5-two chloro-4-(1,1,2,2-tetrafluoro ethyoxyl) phenyl amino) carbonyl]-2,6-difluoro benzamide

Structural formula is:

Weight ratio between compound in insecticides of the present invention (A) and the compound (B) generally is:

(A) Rynaxypyr is 1 with (B) fluorine bell urea: 1-50

Pesticidal combination provided by the present invention possesses characteristic of wide insecticidal spectrum, can effectively prevent and treat the insect of diamond-back moth, prodenia litura and other crop etc.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 insect that prevents and treats diamond-back moth, prodenia litura and other crop etc.Do spraying at the insect pest initial stage of origination and handle, the method for processing can be by adding the good composition of formula or before use that the different activities component is mixed and handled.

Adoptable surfactant has anionic surfactant and nonionic surface active agent.The aliphatic alcohol sulfate that comprises Sulfates, alkylol polyoxyethylene groups ether sodium sulfate etc., the sodium alkyl sulfonate of Sulfonates, alkylbenzenesulfonate, alkylnaphthalene sulfonate, dialkyl succinylsuccinate sulfonate, monoalkyl phenyl polyoxyethylene groups ether succinic acid sulfonate, fatty alcohol ethylene oxide adduct sulfonate, alkylphenol formaldehyde condensation product ethylene oxide adduct sulfonate, fatty alcohol epoxy vinyl ether, alkylphenol-polyethenoxy base ether, the anhydrous sorbitol fatty acid ester, anhydrous sorbitol aliphatic acid polyethenoxy base ether, alkylphenol formaldehyde condensation product polyoxyethylene groups ether, sulfonation castor-oil plant alkoxide, quaternary ammonium salt derivative, the condensation product of oxirane and nonyl or octyl phenol is the main product or the alkalies and alkaline earth salt of sulfuric ester and sulfonic acid, as sulphonyl amber ester octyl group sodium in two ninth of the ten Heavenly Stems and such as the alkali of the macromolecule sulfonic acid derivative of sodium lignin sulfonate and calcium and the carboxylate of the anhydrous sorbierite that the alkali salt condensation forms etc.That can give an example has farming breast No. 2000 series, petroleum sodium sulfonate, dodecyl sodium sulfates, draws back powder, ethoxylated dodecyl alcohol sodium sulfonate, tween series, dispersing agent MF, NNO etc.

Missible oil of the present invention is that the mixture with each active component is dissolved in the solvent toluene, adds suitable emulsifier allotment and forms.Can optionally add auxiliary agents such as suitable stabilizing agent, bleeding agent.The content of active principle is 1-40% (weight) (the more excellent 5-30% of being) in the missible oil.

Wetting powder of the present invention 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.

The preparation of granule of the present invention is that active ingredient is sprayed at particulate inert material surface with absorption property or active ingredient is adhered to carrier mass surface or particulate inert material surfaces such as sand, kaolin with adhesives such as polyvinyl alcohol, Sodium Polyacrylate or mineral oil, also can the active ingredient that some is suitable be processed into granule with the method for common manufacturing granular fertilizer.Its active constituent content of dispersible granules agent (weight) between 5-90% in the water spreads fertilizer over the fields active constituent content (weight) between 1-50% in the granule, between the preferred 1-25%.

Pesticidal combination provided by the invention possesses the insecticide efficiency height, can effectively prevent and treat cabbage caterpillar, diamond-back moth, cotton bollworm, mythimna separata of damage to crops etc.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 high poison, high residue and insecticide pesticide kind.The present invention not only has ecological significance, also has important environment protection significance simultaneously.

Following examples describe the present invention in detail, and embodiment mainly is for the present invention is described but not is used for limiting the present invention.
