Description
Technical field
The present invention relates to a kind of pesticidal preparations, particularly a kind of fipronil bisamide and rotenone compound insecticidal water dispersible granules and preparation method thereof.
Background technology
Water dispersible granules is to go out a kind of pesticides new formulation growing up America and Europe the eighties in 20th century, and international pesticide industry federation of association (GIFAR) is defined as: the granule using after disintegration and dispersion in water.Water dispersion granule mainly contains the compositions such as pesticide active ingredient, dispersant, wetting agent, binding agent, disintegrant and filler, and particle diameter is 200 μ m-5mm, enters disintegration rapidly after water, disperses, and forms higher suspension dispersion; Water dispersible granules can not cause dust (during use) seldom even substantially, thereby has reduced the toxicity in operating process; Water dispersible granules can not flow, make to measure more convenient, be easy to packing.
Fipronil bisamide (flubendiamide), chemical name is the iodo-N ' of 3--(2-mesyl)-1,1-dimethyl ethyl group-N-{4-[1,2,2,2-tetrafluoro-1-(trifluoromethyl) ethyl]-0-tolyl } phthalic amide.Belong to Novel ortho benzenedicarboxamide insecticides, insect ryania (muscle) receptor activators, completely different from the mechanism of action of insecticide in the past, can make excessively to discharge calcium ion in insect bodies, cause insect death.This insecticide does not produce cross resistance with existing insecticide, and efficient, safety, is rising novel pesticide.
Rotenone (rotenone) belongs to flavonoids, its chemical name is [2R-(2 α, 6a α, 12a α)]-1,2.12,12a-tetrahydrochysene-8,9-dimethoxy-2-(1-methoxy vinyl)-[I]-chromene [3,4-b]-furans is also-[2,3-h] [1]-chromene-6 (6aH)-one, mainly come from the plants such as trifoliate jewelvine, Africa mountain soya bean, its Action mechanism is special, insect is had to more significant stomach toxicity and contact toxicity, and have food refusal and the inhibition activity of growing concurrently.Can be used for the various pests control on vegetables, fruit tree, paddy rice, tea tree, tobacco and cotton.The rotenone product of applying on pesticide market is at present main mainly with missible oil.
The fipronil bisamide of applying on existing pesticide market and rotenone product Shortcomings part, rotenone be take missible oil as main, and the formulation of fipronil bisamide pesticide product is mainly suspending agent; Cream preparation is generally used the toxic organic solvent such as dimethylbenzene; At present, the composite water dispersible granules of fipronil bisamide and rotenone has no bibliographical information.
Summary of the invention
The object of the invention is to overcome the shortcoming that prior art exists, a kind of high-efficiency low-toxicity, low cost, environmentally friendly are provided, can prevent and treat beet armyworm, diamond-back moth, cotton bollworm and the significant fipronil bisamide of cabbage aphid effect and rotenone and composite water dispersible granules novel agrochemical insecticide.
Another object of the present invention is to provide the preparation method of above-mentioned fipronil bisamide and the composite water dispersible granule insecticide of rotenone.
The composite use of fipronil bisamide and rotenone, can work in coordination with and play a role, and improves insecticide efficiency, strengthens control efficiency, delays pest resistance to insecticide, has made up self deficiency of single dose agricultural chemicals.
The composite water dispersible granules of fipronil bisamide and rotenone, in formula, the percentage by weight of each component is: fipronil bisamide 0.1%-65%, rotenone 5%-15%, dispersant 3%-25%, wetting agent 3%-5%, disintegrant 1%-25%, binding agent 0.1%-0.5%, stabilizing agent 0.1%-0.5%, carrier 10%-60%.
Described dispersant is one or more in acrylate homopolymer sodium salt, phenethyl phenol polyethenoxy sodium sulphate, sodium lignin sulfonate, Fluhyzon formaldehyde condensation products, alkylbenzenesulfonate, alkylphenol polyoxyethylene formaldehyde condensation products.
Described wetting agent is one or more in sodium alkyl sulfate, alkylnaphthalene sulfonate, benzyl naphthalene sulfonate, benzyl naphthalenesulfonate formaldehyde condensation compound, dialkyl group naphthalene sulfonate, fatty acid amide N methyl taurine salt.
Described disintegrant is one or more in ammonium sulfate, bentonite, polyethylene glycol, modified starch, White Carbon black, silica gel.
Described binding agent is one or more in Sodium Polyacrylate, wooden sodium, dextrin, sodium carboxymethylcellulose, xanthans.
Described stabilizing agent is one or more in niter cake, another name for sodium, citric acid, carbonic hydroammonium, sodium hydroxide.
