Problems solved by technology

[0004] Cotton seedling diseases are mainly caused by three kinds of fungal infection, including cotton seedling red rot, cotton seedling anthracnose and blight, which seriously affect the growth and survival rate of cotton seedlings, and often cause large-scale occurrence of cotton seedling diseases, resulting in rot. Seedlings, rotten roots, dead seedlings or uneven emergence will seriously affect the growth of cotton and reduce cotton yield
Fungicide treatment of cotton seeds can effectively prevent and control cotton seedling diseases, but in recent years, the varieties of fungicides have aged and the control effect has decreased, seriously affecting the control of seedling diseases

Embodiment 1

[0016] A cotton seed coating agent, the mass percentage of each raw material is: sweet potato starch-based superabsorbent resin 28%, imidacloprid 25%, acephate 12%, carbendazim 18%, thiophanate-methyl 15%, thickening 8% agent, 0.8% dyeing agent, 5% defoamer, and the balance is water.

[0017] Among them, the preparation method of sweet potato starch-based superabsorbent resin is: after gelatinizing sweet potato starch, add potassium persulfate, acrylic acid and glycerin in sequence, stir thoroughly, and then put it into a blast drying oven for drying at a drying temperature of 70 ° C. After crushing, the sweet potato starch-based superabsorbent resin is obtained.

Embodiment 2

[0019] A cotton seed coating agent, the mass percent of each raw material is: sweet potato starch-based superabsorbent resin 25%, imidacloprid 22%, acephate 10%, carbendazim 15%, thiophanate-methyl 15%, thickening 5% agent, 0.5% dyeing agent, 3% defoaming agent, and the balance is water.

[0020] Among them, the preparation method of sweet potato starch-based superabsorbent resin is: after gelatinizing sweet potato starch, add potassium persulfate, acrylic acid and glycerin in sequence, stir thoroughly, and then put it into a blast drying oven for drying at a drying temperature of 70 ° C. After crushing, the sweet potato starch-based superabsorbent resin is obtained.

[0021] Use effect: every 100kg seed is used the cotton seed coating agent 500mL that above-mentioned embodiment of the invention prepares when cotton sowing seed dressing, and the seedling preservation effect and relative control effect to cotton seedling stage disease all reach more than 90%, can effectively pr...

Abstract

The invention discloses a cotton seed coating agent. The coating agent is characterized by comprising sweet potato starch super absorbent polymer, imidacloprid, acephate, carbendazim, thiophanate methyl, thickener, stain, defoamer and water. The cotton seed coating agent can keep more water around cotton seedlings, and it is ensured that the seedlings can also grow normally under the conditions ofdrought. At the same time, the cotton seed coating agent can penetrate seed coats to kill pathogenic bacteria, effectively prevent diseases in the period of the cotton seedlings, and play the roles of seedling protection and seedling promotion.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a cotton seed coating agent. Background technique [0002] Cotton was once an important strategic material in my country and played a pivotal role in the agricultural economic structure. my country's cotton production ranks among the top in the world. It is a large textile country and the largest cotton consumer. There are 23 provinces, municipalities and autonomous regions that produce cotton. The cotton industry occupies an important position in the national economy. [0003] Seed coating, also known as seed coating agent, is made of pesticides (insecticides, fungicides, etc.), fertilizers, growth regulators, film-forming agents and supporting auxiliaries through specific technological processes. It can be directly or through It is a pesticide preparation coated on the surface of seeds after dilution to form a protective film with certain strength and permeability. [0004...
