Problems solved by technology

[0002] At present, the seed coating agents used in China are mainly organophosphorus pesticides, most of which contain highly toxic pesticides such as carbofuran and isofenphos-methyl, which have poor safety; in addition, most of them are wet suspensions that are easy to separate, have poor stability and are inconvenient to use

Embodiment 1

[0018] Weigh 49 grams of Reproxil, 150 grams of carbendazim, 1 gram of benzylamine and mix evenly, add 50 grams of calcium lignosulfonate, 50 grams of sodium carboxymethyl cellulose, 0.1 grams of copper sulfate, 0.05 grams of boric acid, molybdenum 0.01 g of ammonium acid, 0.01 g of zinc sulfate, and then add bentonite to 699.83 g. After mechanical primary crushing, airflow crushing is carried out to make the particle size below 5 microns.

[0019] When used, add water for preparation. Each kilogram of dry suspending seed coating agent can dress 40 kilograms of cotton seeds. The agent can form a drug film on the cotton seeds and release slowly.

Embodiment 2

[0021] To prepare a dry suspension seed coating:

[0022] 1), according to the mass percentage of each raw material: 1, carbendazim, 15.908, benzedramine 0.08, lignosulfonate 4, carboxymethyl cellulose sodium salt 4, bentonite 75, trace element Substance 0.012 Select fipronil, carbendazim, benzylamine, lignosulfonate, carboxymethylcellulose sodium salt, bentonite and trace element-containing material raw materials for use, among which the trace element-containing substances are boric acid and molybdenum Ammonium acid, zinc sulfate, boric acid, ammonium molybdate, and zinc sulfate each account for a mass percentage of 0.004;

[0023] 2), fipronil, carbendazim, benzedramine, lignosulfonate, carboxymethylcellulose sodium salt, bentonite and substances containing trace elements were first mixed for primary crushing, and then jet crushing to check the particle size. Degree and suspension rate, 95% of the particle fineness is less than 5 microns, and the suspension rate is greater ...

Embodiment 3

[0026] To prepare a dry suspension seed coating:

[0027] 1), according to the mass percentage of each raw material: 6 fipronil, 16.778 carbendazim, 0.2 benzylamine, 6 lignosulfonate, 6 carboxymethyl cellulose sodium salt, 65 bentonite, trace element Substance 0.022 selects fipronil, carbendazim, benzylamine, lignosulfonate, carboxymethylcellulose sodium salt, bentonite and trace element-containing material raw materials for use, and the trace element-containing material is boric acid , ammonium molybdate, zinc sulfate, manganese sulfate, and copper sulfate, the ratio of which is: boric acid, ammonium molybdate, zinc sulfate, manganese sulfate, and copper sulfate each account for a mass percentage of 0.0044;

[0028] 2), fipronil, carbendazim, benzedramine, lignosulfonate, carboxymethylcellulose sodium salt, bentonite and substances containing trace elements were first mixed for primary crushing, and then jet crushing to check the particle size. Degree and suspension rate, 95...

Abstract

A suspended dry coating agent of seeds for preventing and eliminating pests and diseases and providing high fertility is proportionally prepared from fipronil, carbendazim, mepiquat chloride, lignin sulfonate, carboxymethyl cellulose sodium, bentone, and the trace elements contained substance chosen from boric acid, ammonium molybdate, zinc sulfate, manganese sulfate, and copper sulfate.

Description

technical field [0001] The present invention relates to a seed coating agent, in particular to a cotton seed coating agent. Background technique [0002] At present, the seed coating agents used in China are mainly organophosphorus pesticides, most of which contain highly toxic pesticides such as carbofuran and isofenphos-methyl, which have poor safety; in addition, most of them are wet suspensions that are easy to separate, have poor stability and are inconvenient to use. Contents of the invention [0003] The object of the present invention is to provide a dry suspension seed coating agent, which has the characteristics of low toxicity, safety, high-efficiency disease prevention and pest control, slow release of fertilizer effect, strong roots and seedlings, and growth regulation. [0004] In order to achieve the above object, the technical scheme of the present invention is: dry suspension seed coating agent, it is characterized in that it is made of fipronil, carbendaz...
