Embodiment 1

[0035] A water-dispersible granule containing glufosinate-ammonium and dicamba, the components of the water-dispersible granule and their mass percentages are: glufosinate-ammonium 5%, dicamba 45%, acrylic acid copolymer sodium salt 6%, dodecyl Sodium alkyl sulfate 2%, ammonium sulfate 5% and attapulgite 37%.

[0036] Furthermore, the composition of glufosinate-ammonium and dicamba in the water-dispersible granule accounts for 50% of the total amount.

Embodiment 2

[0038] A water-dispersible granule containing glufosinate-ammonium and dicamba, the components of the water-dispersible granule and their mass percentages are: 1% glufosinate-ammonium, 49% dicamba, 15% sodium lignosulfonate, alkane 2% aryl polyoxyethylene ether sulfate, 15% anhydrous sodium sulfate, 17% diatomaceous earth and talcum powder as filler.

Embodiment 3

[0040] A water-dispersible granule containing glufosinate-ammonium and dicamba, the components of the water-dispersible granule and their mass percentages are: glufosinate-ammonium 10%, dicamba 50%, acrylic acid copolymer sodium salt and lignosulfonic acid Sodium salt mixture 4%, naphthalene sulfonate and sodium lauryl sulfate mixture 6%, anhydrous sodium sulfate and sodium carboxymethyl starch 5%, filler is kaolin 35%.

[0041] A kind of preparation method of the water dispersible granule containing glufosinate-ammonium and dicamba, concrete steps are as follows:

[0042] (1) Fully mix the original drug glufosinate-ammonium and dicamba, dispersant, wetting agent, disintegrant and filler according to the ratio required by the formula, and coarsely pulverize it by a pulverizer;

[0043] (2) The coarsely pulverized sample is subjected to superfine pulverization through a jet mill;

[0044] (3) Finally, add a certain amount of water to the sample obtained by superfine grinding a...

Abstract

The invention discloses water dispersible granules containing glufosinate-ammonium and dicamba. The water dispersible granules are prepared from the following raw materials in weight percent: 1%-10% of glufosinate-ammonium, 5%-60% of dicamba, 4%-15% of a dispersant, 2%-6% of a wetting agent, 5%-15% of a disintegrating agent and the balance of fillers. A preparation method of the water dispersible granules containing glufosinate-ammonium and dicamba comprises the following steps: mixing and crushing, carrying out superfine grinding, kneading and granulating to obtain the water dispersible granules. When being used, a herbicide composition has no dust hazards and is convenient to pack and transport; an organic solvent is not used so that problems of flammability and chemical injury are not generated; the use effect is obviously better than that of single utilization of each single dosage and a current problem of weed drug resistance is greatly alleviated; the weeding spectrum is expanded and the dosage is reduced; and the water dispersible granules have low toxin and high efficiency, are environmentally friendly and safe to human and livestock, and accord with a development trend of green and environmental protection of the future society.

Description

technical field [0001] The invention belongs to the technical field of pesticides, relates to the technical field of herbicides, in particular to a water-dispersible granule containing glufosinate-ammonium and dicamba and a preparation method thereof. Background technique [0002] Water-dispersible granules are also called dry suspension concentrates or granular wettable powders. Once put into water, they can disintegrate and disperse quickly to form granular preparations with a high-suspension solid-liquid dispersion system. It is a new dosage form developed on the basis of wettable powder and suspending agent. It has the characteristics of good dispersibility, high suspension rate, good stability, and convenient use. It avoids the dust generated by wettable powder. Suspending agent packaging and transportation Inconvenient, storage is prone to disadvantages such as precipitation, agglomeration, poor fluidity, and sticking to the wall. Water-dispersible granules, as an imp...
