Problems solved by technology

[0002] Labor-saving is the future development trend of pesticide formulations. With the rapid development of urbanization and the intensification of social aging, the rural labor force is gradually decreasing. The traditional method of spraying with a sprayer on the back is difficult to adapt to the current situation of labor shortage. The development and application of simple labor-saving Chemical pesticide products such as floating granules are one of the effective ways to solve the problem of difficult pesticide application

Embodiment 1

[0028] 2% pyrazosulfuron-methyl floating granules, including pyrazosulfuron-methyl, hollow glass beads, carboxymethyl starch and sodium sulfate, kaolin, citric acid, and a diffusing agent. 5% of the pesticide preparation; the diffusing agent consists of the following components by weight: 70 parts of isomeric alcohol polyoxyethylene ether, and 80 parts of polycarboxylate dispersant.

[0029] The preparation method of 2% pyrazosulfuron-methyl floating granule comprises the steps:

[0030] Step 1: Weigh each component of the above-mentioned diffusing agent, and mix them evenly in a blender;

[0031] Step 2: Weigh the pyrazosulfuron-methyl original drug, the diffusing agent obtained in step 1, the carrier and other additives that have been processed in advance by jet crushing, and mix evenly, and add an appropriate amount of water while stirring to make the material wet and easy to extrude and granulate .

[0032] Step 3: Put the wet material into an extruder to extrude into cy...

Abstract

The invention discloses a diffusant, floating granules containing the same and a preparation method of the floating granules and belongs to the field of processing of pesticide preparations. The diffusant is prepared from components in parts by weight as follows: 0-50 parts of sodium fatty alcohol ether sulfate, 20-70 parts of fatty alcohol polyoxyethylene ether, 30-80 parts of a polycarboxylate dispersant and 0-40 parts of sorbitan fatty acid ester. The diffusant can endow the pesticide floating granules with good water surface diffusion performance, so that the prepared pesticide floating granules have a good diffusion effect and long diffusion distance in water.

Description

technical field [0001] The invention relates to the field of pesticide preparation processing, in particular to a diffusing agent, a floating granule containing the diffusing agent and a preparation method thereof. Background technique [0002] Labor-saving is the future development trend of pesticide formulations. With the rapid development of urbanization and the intensification of social aging, the rural labor force is gradually decreasing. The traditional method of spraying with a sprayer on the back is difficult to adapt to the current situation of labor shortage. The development and application of simple labor-saving Chemical pesticide products such as floating granules are one of the effective ways to solve the problem of difficult pesticide application. Floating granule is a pesticide dosage form that can be automatically dispersed and expanded on the water surface. It is mostly used to prevent and control diseases, insect pests and weeds in rice fields. It is widely...
