Abstract
The invention relates to water-dispersible granules for methylamino abamectin benzoate. The water-dispersible granules comprise the following components in percentage by weight: 1 to 30 percent of methylamino abamectin benzoate, 10 to 20 percent of wetting dispersing agent, 1 to 50 percent of disintegrating agent, 0.1 to 5 percent of stabilizing agent and 35 to 75 percent of carrier. By a formula of the water-dispersible granules, the technical problem of preparing the water-dispersible granules from the methylamino abamectin benzoate is solved, the solvent cost, packaging cost and transport cost are reduced, and the water-dispersible granules are convenient to store and transport; and an adhesion agent is not needed to be used, the quality of products is improved greatly, the medicinal effect is improved by over 20 percent, and the using period of the products is prolonged by the stabilizing agent.
Description
Technical field
The present invention relates to a kind of pesticidal preparations, specifically be meant the water dispersible granules that contains emamection benaoate.
Background technology
Emamectin-benzoate (being called for short first dimension salt) is a kind of super-high-efficient green pesticide, the characteristics that have super-high-efficient, wide spectrum, closely nontoxic, noresidue, do not develop immunity to drugs are assert that in the industry will replace other insecticides becomes 21 century insecticide leading products.The present industrially developed country in the world of emamectin benzoate insecticidal agent has been widely used in the control of grain, economic crops and vegetable-crop pest-insect.First dimension salt pref is still based on missible oil at present, and about 88% (weight ratio) is that toluene, dimethylbenzene, methyl alcohol etc. bring the organic solvent of influence to the mankind and environment in the preparation.Solvent used in the cream preparation not only brings influence to environment, and has increased the expense of the preparation cost of raw material and packaging material and transportation, so the exploitation of environmental protection preparation is the development trend that replaces cream preparation.
Water dispersible granules is a kind of pesticides new formulation that grows up the eighties in 20th century, is the more comprehensive and more perfect product of combination property in the current pesticidal preparations, has the advantage of solid pharmaceutical preparation (granula and wetting powder) and liquid preparation (suspending agent etc.).Patent documentation 1 (200810198637.0) relates to a kind of water dispersible granules of emamection benaoate, contain binding agent in its component, be convenient to be shaped, but because the adhesive effect of binding agent, cause that the product dispersion effect is poor, drug effect is difficult to good performance, also have product, easily problem such as inefficacy poor at shelf life stability.
Summary of the invention
The technical problem to be solved in the present invention is the defective that overcomes the water dispersible granules of existing emamection benaoate, and a kind of binding agent that do not contain is provided, dispersion effect is good, good stability the water-dispersible grain agent prescription.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
The water dispersible granules of emamection benaoate, it comprises the component of following weight proportion: emamection benaoate 1-30%, wetting dispersing agent 10-20%, disintegrant 1-50%, stabilizing agent 0.1-5%, carrier 35-75%.
Further, described wetting dispersing agent is any or the arbitrarily combination in phenethyl phenol polyethenoxy sodium sulphate, alkyl naphthalene sulfonic acid condensation polymer sodium salt, fatty alcohol-polyoxyethylene ether, lignosulfonates, sodium methylene bis-naphthalene sulfonate, dispersing agent MF, naphthalene sulfonate, alkyl benzene calcium sulfonate, ethoxylated nonylphenol, sodium alkyl sulfate, the lauryl sodium sulfate.These dispersants all have certain adhesive effect, prove through experimental study, and the dispersant of an amount of ratio and the reasonable combination of other components can be brought into play required bonding effect fully.
Described disintegrant is any or the combination arbitrarily in bentonite, attapulgite, mineral salt, white carbon black, calgon, the silica gel.
Described stabilizing agent is any or the arbitrarily combination in epoxychloropropane, epoxy linseed oil, antodyne, the epoxidised soybean oil.Stabilizing agent can prevent that product is rotten in the storage life, lose efficacy.
Described carrier is any or the combination arbitrarily in kaolin, starch, potter's clay, the white carbon black.
The preparation of above-mentioned water dispersible granules can be adopted manufacturing process such as extruder grain, technology simple controllable; Prescription of the present invention has overcome emamectin-benzoate and has prepared the technical barrier that water dispersible granules exists, and has reduced solvent cost, packing cost and freight, and the storage convenient transportation; Avoided the use of binding agent, product quality improves a lot, and drug effect improves more than 20%, and stabilizing agent has increased the life cycle of product.
