Description
Technical field
The present invention relates to a kind of pesticidal preparations, particularly a kind of Rynaxypyr and the composite water dispersible granules of nimbin and preparation method thereof.
Background technology
Water dispersible granules is to go out a kind of pesticides new formulation that grows up the America and Europe eighties in 20th century, and international pesticide industry federation of association (GIFAR) is defined as it: the granule that use disintegration and dispersion back in water.Water dispersion granule mainly contains compositions such as pesticide active ingredient, dispersant, wetting agent, binding agent, disintegrant and filler, and particle diameter is 200 μ m-5mm, and disintegration rapidly after the entry disperses, and forms the higher suspension dispersion; Water dispersible granules seldom even substantially can not cause dust (during use), thereby has reduced the toxicity in the operating process; Water dispersible granules can not flow, and makes that metering is more convenient, is easy to packing.
Rynaxypyr (chlorantraniliprole), chemical name is for being 3-bromo-N-{4-chloro-2-methyl-6-[(methylamino) carbonyl] phenyl }-1-(3-chloro-2-pyridine radicals)-1H-pyrazoles-5-acid amides, be a kind of novel adjacent formamido benzamide insecticides that du pont company develops.This insecticide is an insect ryania acceptor inhibitor, mainly discharges by the intracellular calcium ion of inducing insect ryania receptor modulators to show insecticidal action [" world's agricultural chemicals ", 2007,29 (5): 6～10].Rynaxypyr has tags and stomach poison function, show efficient, wide spectrum, hold characteristics such as effect and mechanism of action novelty, can be used for preventing and treating multiple lepidoptera pest, other commercialization insecticide varieties that its control efficiency obviously is better than using in the current production, there is not cross resistance in other insecticides, and to natural enemy insect safety, can be used for the insect comprehensive regulation and resistance management, be used in vegetables, beet, crops such as cotton prevent and treat various insects, as beet armyworm (Spodoptera exigua), tomato moth (Spodoptera litura), diamond-back moth (Plutella xylostella), imported cabbageworm (Pieris rapae), cotton bollworm (Heliothis armigera), pink bollworm (Peatinophora gossypiella) etc. all has good control efficiency to each instar larvae.Rynaxypyr is described as efficient pesticides of new generation in the world.The Rynaxypyr product is mainly suspending agent in the market.
Nimbin (azadirachtin) is acknowledged as has the effect that food refusal, stomach toxicity and inhibition are grown to insect, its mechanism of action mainly is to upset the internal secretion of insect, action target is that influences such as cerebral nerve secretory cell, corpora cardiaca, prothoracic gland promote the synthetic of thymin and discharge, lower prothoracic gland and the induction of prothoracic gland hormone is caused the 20-hydroxyecdysone is synthetic, hyposecretion, cause the insectean metamorphosis impaired development.The nimbin preparation shows different physiologically actives to kind of insect surplus 400.Have advantages such as higher mammal low toxicity, low-residual, insect are difficult for developing immunity to drugs.
There are weak point in Rynaxypyr and the nimbin product used on the existing agricultural chemicals market, nimbin is based on missible oil, the formulation of Rynaxypyr pesticide product is mainly suspending agent, and cream preparation often uses toxic organic solvent such as dimethylbenzene, the shortcoming that the existing product formulation is more single.At present, the composite water dispersible granules of Rynaxypyr and nimbin does not appear in the newspapers.
Summary of the invention
The objective of the invention is to overcome provides a kind of high-efficiency low-toxicity, low cost, environmentally friendly, prevents and treats paddy rice white-backed planthopper, diamond-back moth, cotton bollworm and rice-stem borer obvious results Rynaxypyr and the composite water dispersible granules novel agrochemical of nimbin insecticide.
Another object of the present invention is to provide the preparation method of above-mentioned Rynaxypyr and the composite water dispersible granule insecticide of nimbin.
The composite use of Rynaxypyr and nimbin can be worked in coordination with and played a role, and improves insecticide efficiency, strengthens control efficiency, delays pest resistance to insecticide, remedies self deficiency of single agent agricultural chemicals.
The object of the invention is achieved through the following technical solutions:
The composite water dispersible granules of a kind of Rynaxypyr and nimbin, the percentage by weight of each component is in the prescription: Rynaxypyr 0.1-60%, nimbin 0.1-15%, 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% and deionized water 1-10%.
Described dispersant is one or more in phenethyl phenol polyethenoxy sodium sulphate, dioctyl sodium sulphosuccinate, sodium lignin sulfonate, Fluhyzon formaldehyde condensation products, alkylbenzenesulfonate, the 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, the fatty acid amide N methyl taurine salt.
Described disintegrant is one or more in ammonium sulfate, bentonite, modified starch, white carbon black, the silica gel.
Described binding agent is one or more in Sodium Polyacrylate, polyethylene glycol, wooden sodium, dextrin, sodium carboxymethylcellulose, the xanthans.
Described stabilizing agent is one or more in niter cake, another name for sodium, citric acid, carbonic hydroammonium, the sodium hydroxide.
Described carrier is one or more in kaolin, diatomite, clay, Emathlite, mica powder, sepiolite, the calcium carbonate.
The preparation technology of described Rynaxypyr and the composite water dispersible granules of nimbin is:
1, one group of Rynaxypyr and the composite water dispersible granules formula material of nimbin are mixed;
2, formula material is ground into female powder through micro jet;
3, female powder and deionized water are mixed, then the granulation of rotating disk squash type;
4, defective granulation, the qualified drier drying that enters of profile then returned again of granulation profile;
5, drying, screening, packing after inspection by sampling is qualified.
Composite water dispersible granules of the present invention is to contain active insecticidal components Rynaxypyr and nimbin.
The present invention utilizes the neem seed of pulverizing to carry out lixiviate, and extract becomes the concentrated extract that contains nimbin behind concentrating under reduced pressure.
Rynaxypyr compared with prior art of the present invention and the composite water dispersible granules of nimbin have following advantage:
(1) the present invention has the suspensibility height, and heat storage stability is good, disintegration rate is fast, good dispersion;
(2) the composite water dispersible granules of Rynaxypyr of the present invention and nimbin is difficult for producing poisoning to environment, people and animals and other beneficial organism safety;
