Description
Technical field
The present invention relates to a kind of agricultural chemicals, relate in particular to a kind of Imidacloprid buprofezin pesticide composition.
Background technology
Rice fulgorid is China's paddy rice important pests, belongs to Homoptera, Delphacidae.Mainly contain three kinds of small brown rice planthopper (Laodelphax striatellus), white-backed planthopper (Sogatella furcifera) and brown planthoppers (Nilaparvata lugens) at Dao Qu, the paddy rice of mainly causing harm, also cause harm simultaneously wheat, corn, sugarcane, Chinese sorghum, broomcorn millet and wild rice stem etc., all there is generation in main rice district in the whole nation.Rice fulgorid is propagated brown of paddy rice stunt disease and stripe virus disease, the vector insect of still propagating wheat rosette stunt and MRDV.Be clustered in rice clump base portion with one-tenth, nymph, thorn is inhaled the juice of cauline leaf tissue, consumes rice strain nutrient, makes grain not full, and thousand kernel weight alleviates, and shrivelled kernel increases; The coagulability saliva of secretion forms " stylophore " during thorn absorption food, hinders the transporting of interior moisture of rice strain body and nutrient.The worm amount is many, being injured causes rice strain bottom blackening when weighing, and it is smelly to rot, and lodging causes the serious underproduction and loses receipts.More serious causes complete stool withered, and agglomerating paralysis lodging forms the yellow pool, even withered lodging in blocks.

30S, other title: excellently readily take the opportunity to, buprofezin, the spirit of rice lice, Buprofezin) belong to a kind of new selective insecticide that insect growth is grown that suppresses, action of contace poison is strong, and stomach poison function is also arranged.Mechanism of action is synthetic and disturb metabolism for suppressing insect chitin, causes nymph cast off a skin deformity or wing deformity and slowly dead.Simultaneously, can make adult shorten the life-span, reduce egg laying amount, and output be mostly addle-egg, even the also very fast death of larva hatching.Double wing purpose plant hopper, leafhopper, aleyrodid and scale insect class pest have good control efficiency.This medicine lasting period length is 35～40 days, and to pest natural enemy and visit flower insect safety.
The synergistic complex of agricultural chemicals is expanding prevention spectrum and the effective measures that improve preventive effect, up to now, still finds no the report that closes Imidacloprid and Buprofezin composition.
Purpose of the present invention just provides a kind of Imidacloprid and buprofezin compound agricultural chemicals, and the expanding prevention spectrum improves its drug effect, reduces the agricultural chemicals usage amount, reduces cost, and reduces environmental pollution.
Summary of the invention
Imidacloprid buprofezin pesticide composition mainly contains Imidacloprid and Buprofezin.
Above-mentioned insecticides mainly contains Imidacloprid 1～20% (percentage by weight, down together) and Buprofezin 5～40%.
Above-mentioned insecticides can be mixed with wetting powder and microemulsion and other formulation according to method known in those skilled in the art,
Above-mentioned insecticides can be formed wetting powder by Imidacloprid 1～20%, Buprofezin 5～40%, dispersant 0.1-30%, filler 10～90%.
Auxiliary agent described in the invention described above wetting powder can be to well known to a person skilled in the art calcium phosphate, talcum powder, 12-sodium alkyl sulfate, 12-sodium alkyl benzene sulfonate, 12-sodium alkyl sulfonate, calcium lignosulfonate, draw back a kind of or any two kinds combination in powder, NNO, sanlose, the carboxymethyl starch etc.; Described filler can be any one in diatomite, white carbon, bentonite, precipitated calcium carbonate, kaolin, the potter's clay etc.This formulation processing technology is with the known wetting powder processing method of present technique field personnel.
Above-mentioned insecticides can be formed microemulsions by Imidacloprid 1～20% (percentage by weight, down together), Buprofezin 5～40%, cosolvent 5～30%, emulsifier 5～30% and water 20～80%.
Used cosolvent can be any one or the two or more combination in cosolvent phenmethylol well-known to those skilled in the art, dimethyl formamide, ethanol, isopropyl alcohol, n-butanol, n-amyl alcohol, acetone, the cyclohexanone in the invention described above microemulsion; Emulsifier described in the invention described above microemulsion can be a farming breast 500
