Abstract
The invention discloses an anti-decomposition bromothalonil-containing wettable pulvis. The anti-decomposition bromothalonil-containing wettable pulvis comprises, by weight, 15-30% of bromothalonil, 5-10% of difenoconazole, 2-5% of a wetting agent, 3-6% of a dispersant, 10-20% of a bromothalonil stabilizer, 0.5-1% of a pH regulator, 5-10% of white carbon black, and the balance of a carrier. A preparation method of the anti-decomposition bromothalonil-containing wettable pulvis comprises the following steps: accurately weighing bromothalonil and the bromothalonil stabilizer (beta-cyclodextrin) according to a certain ratio, fully and uniformly mixing bromothalonil and the bromothalonil stabilizer, crushing the obtained mixture through a mechanical crusher, adding white carbon black, an assistant and the carrier, and uniformly mixing all above raw materials; and carrying out ultrafine crushing on the obtained mixture to obtain the anti-decomposition bromothalonil-containing wettable pulvis. The anti-decomposition bromothalonil-containing wettable pulvis overcomes the disadvantages of easy decomposition of bromothalonil, and fully performs the application drug effect of bromothalonil.
Description
Technical field
The present invention relates to a kind of disinfectant use in agriculture, the pesticidal preparations containing bromothalonil of a kind of antidecomposition and
Its preparation method.
Background technology
Bromothalonil is a kind of wide spectrum, efficient, the antibacterial of low toxicity, can suppress and root out the growth of fungus, antibacterial, algae,
Corps diseases is had preferable prevention effect, anthrax is had specially good effect, be widely used in fruit tree, Fructus Vitis viniferae, vegetable, Cotton Gossypii, flower
The various crop such as life, Citrullus vulgaris, Nicotiana tabacum L., Camellia sinensis, flowers, preventing and treating anthrax, scab, shot hole, powdery mildew, rust, damping-off,
Multiple fungoid, the bacteroidal diseases such as damping off, rhizome maize ear rot, Peptic Ulcers, bacterial wilt, angular leaf spot.Application mode is flexible, leaf
Face spraying, seed treatment and soil pouring root, all show preferable preventive effect.Apply also for the algae removal that lake environment processes, improve
Fishing pool water quality；The anticorrosion such as textile, leather, gas defence etc..
Owing to there is nitrogen three key in bromothalonil former medicine structural formula, during storing, this key is easily broken off, and causes former medicine
Decompose, so in pesticide manufacture process, there is the biggest hidden danger of quality；Therefore finding suitable stabilizer is the technology of most critical,
I takes charge of by a large amount of theoretical researches and experiment sieving, eventually finds beta-schardinger dextrin-, owing to it has space circulus, energy and bromine
Bacterium nitrile forms inclusion complex, thus stops it to decompose, and to regulate preparation pH value be acid condition, can solve bromothalonil preparation
The problem decomposed.
Summary of the invention
It is an object of the invention to solve the problem that bromothalonil decomposes in pesticidal preparations product, it is provided that a kind of antidecomposition
Wettable powder containing bromothalonil.
The present invention is realized by techniques below scheme: the wettable powder containing bromothalonil of a kind of antidecomposition, comprises
Each component of following percentage by weight: bromothalonil 15%～30%, Difenoconazole 5%～10%, wetting agent 2%～5%, point
Powder 3%～6%, bromothalonil stabilizer 10%～20%, pH value regulator 0.5%～1%, white carbon 5%～10%, remaining
Amount is carrier.

The mixing of one or more in salt, fatty alcohol-polyoxyethylene ether, sodium alkyl benzene sulfonate, alkylnaphthalene sulfonate.
Described dispersant is selected from alkylphenol polyoxyethylene formaldehyde condensation products, polyoxyethylenated alcohol sodium sulfate, gathers
Carboxylate, naphthalenesulfonate formaldehyde condensation compound, to the mixing of one or more in methoxyl group fatty acyl anilinesulfonic acid.
Described bromothalonil stabilizer is beta-schardinger dextrin-.
Described pH value regulator is citric acid.
Described carrier is in Kaolin, corn starch, kieselguhr, attapulgite, Pulvis Talci, montmorillonite, potter's clay
The mixing of one or more.
The preparation method of the wettable powder containing bromothalonil of described a kind of antidecomposition, step is as follows:
(1) each component is the most accurately weighed；
(2) bromothalonil and beta-schardinger dextrin-are sufficiently mixed uniformly, then after mechanical crusher is pulverized, add rest materials, fill
Divide mixing；
(3) jet mill is opened so that it is by 1000 mesh standard sieves after pulverizing；
(4) wettable powder of the present invention is i.e. obtained after analytical control.
The present invention efficiently solves the problem that bromothalonil decomposes in pesticidal preparations product, is conducive to improving containing bromothalonil
The quality stability of product.
