Abstract
The invention belongs to a synergic insecticidal composition which is a mixture comprising flubendiamide as a compound (A) and imidacloprid as a compound (B). The insecticidal composition provided by the invention can be processed into an emulsifiable solution, a suspension, a wettable powdery agent and water dispersible granules. In the invention, the weight ratio of the flubendiamide as the compound (A) and the imidacloprid as the compound (B) is (1-100):(1-100). The insecticidal composition provided by the invention has high insecticidal efficiency and can be used for effectively preventing and treating various pests on various crops such as paddy and the like. The insecticidal composition has a higher preventing effect than the single compound (A) or the single compound (B), and the application dosage of each active substance is greatly reduced. The invention not only has an ecological meaning, but also has an important environmental protection meaning.
Description
Technical field
The present invention relates to have the Pesticidal combination of synergism performance, relate to Synergistic insecticidal compositions that contains fipronil bisamide and Imidacloprid and uses thereof specifically.
Background technology
The fipronil bisamide general by name of compound (A), English name: flubendiamide, by Japanese agricultural chemicals company (claiming Co., Ltd.) invention initiative, test code number is NNI-0001, and has obtained patent.The CAS accession number is 272451-65-7.Chemical name be 3-iodo-N '-(2-mesyl-1,1-dimethyl ethyl group-N-{4-[1,2,2,2-tetrafluoro-1-(trifluoromethyl) ethyl]-the 0-tolyl phthalamide, belong to novel phthalyl amine agricultural chemicals.Its mechanism of action is for activating calcium release channel in blue Buddhist nun's alkali recipient cell, the property out of control release that causes storing calcium ion.It is the compound that acts on blue Buddhist nun's alkali (Ryanodine) acceptor of insect cell at present few in number.Lepidoptera pest there is the wide spectrum preventive effect, does not have cross resistance with existing insecticide and produce, be suitable for very much the control that existing insecticide produces the insect of resistance.Larva there is very outstanding preventive effect, limited to the adult preventive effect, there is not ovicidal action.Slightly conduct by xylem the back in the infiltration plant body.Resistance of rainwater washing against.
Fipronil bisamide can be prevented and treated striped rice borer, paddy stem borer, rice leaf roller, plant hopper, melon thin,tough silk snout moth's larva, the lima bean pod borer on paddy rice, leaf vegetables, vegetable category vegetables, leguminous vegetable, cotton, the seeding corn and other crops; Various pests such as cotton bollworm, prodenia litura, beet armyworm, corn borer.
Single preparation of the fipronil bisamide of using on market at present is water dispersible granules and the Avermectin of Bayer Cropscience (China) Co., Ltd registration and the suspending agent of fipronil bisamide mixture preparation of Nihon Nihyaku Co., Ltd's registration.
The adopted name of compound (B) is: Imidacloprid, English general by name: imidacloprid, it is clean etc. that other name is called imidacloprid, Gao Qiao, person who has rendered outstanding service, aphid lice.Chemical name is: 1-(6-chloro-3-pyridylmethyl)-N-Nitroimidazoline-2-base amine, and the CA registration number is: 105827-78-9; 138261-41-3.Report at first that by A.Elbert al. Japanese special agricultural chemicals manufacturing company and Bayer A.G exploitation obtain patent EP0192060 (1986), US4742060 (1988).Beginning developmental research in domestic 1991 has had many enterprises to produce former medicine and various preparation at present.Imidacloprid at present on market most widely used formulation be wetting powder.
Compound (B) Imidacloprid belongs to the nitro-methylene-type systemic insecticide, selectivity suppresses the nicotinic acid acetylcholinesterase acceptor in the insect nervous system, thereby combine the normal conduction of the nervous centralis that destroys insect with its high competitiveness, make it dead after the neural paralysis.The mode of action is mainly stomach toxicity and tags, and has systemic activity concurrently.
Compound (B) Imidacloprid is of many uses, can be widely used in preventing and treating the control of insect on the various crop such as cereal crop, corn, paddy rice, potato, beet, cotton, oranges and tangerines, deciduous fruit tree and vegetables.
Fipronil bisamide and Imidacloprid amine 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.
Summary of the invention
The Pesticidal combination that the purpose of this invention is to provide fipronil bisamide and Imidacloprid, 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 granules, be used to prevent and treat the insect on the various crop such as paddy rice.
Pesticidal combination provided by the invention is characterized in that comprising compound (A) fipronil bisamide and compound (B) Imidacloprid.Weight ratio between compound in insecticides of the present invention (A) and the compound (B) generally is:
(A) fipronil bisamide is 1-100: 1-100 with (B) Imidacloprid.
Pesticidal combination provided by the present invention can effectively be prevented and treated the insect on the various crop such as paddy rice.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.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 newborn 2000 series of farming, No. 500, farming breast, No. 33, farming breast, No. 34, farming breast, lignosulfonates, NNO, a dispersing agent MF etc.
