Abstract
The invention relates to an insecticidal composition containing nitenpyram and a preparation method and a use thereof, and the insecticidal composition is a mixture consisting of a compound nitenpyram (A) and a compound (B) consisting of at least one of chlorpyrifos and dichlorvos. The insecticidal composition can be prepared into missible oil, wettable powder and granules. The insecticidal composition has the characteristics of broad insecticidal spectrum and can effectively prevent and treat a variety of crop pests and the like. The prevention effect is significantly higher than that of the compound (A) or the compound (B) and can reduce the doses of various biological active substances.
Description
Technical field:
The present invention relates to have the Pesticidal combination of synergism performance.
Background technology
The Nitenpyram general by name of compound (A), 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.Domestic and international using with of also not mentioned it and chlopyrifos of patent, dichlorvos in addition, so it and chlopyrifos, dichlorvos immixture are unforeseen.
Summary of the invention
Pesticidal combination provided by the invention is characterized in that comprising compound (A) Nitenpyram and at least aly is selected from one group of compound compound (B) that chlopyrifos, dichlorvos are formed.They are respectively:
Compound (A):
Nitenpyram: (E)-N-(6-chloro-3-picolyl)-N-ethyl-N '-methyl-2-nitro ethylene diamine
Structural formula is:
Compound (B):
(B1) chlopyrifos O-O-diethyl-O-(3,5, the 6-trichloro-2-pyridyl) phosphorothionate
(B2) dichlorvos: O, O-dimethyl-O-(2, the 2-dichloroethylene) phosphate
Weight ratio between compound in insecticides of the present invention (A) and the compound (B) generally is:
(A) Nitenpyram is 1 with (B1) chlopyrifos: 1-50
(A) Nitenpyram is 1 with (B2) dichlorvos: 1-60
Pesticidal combination provided by the present invention possesses characteristic of wide insecticidal spectrum, effectively control various crop pests 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 for control various crop pests 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 the insect of harm various crop.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.
Embodiment 1 is the formulation preparation example, and embodiment 2-3 is a biological Examples.
