Problems solved by technology

[0003] Traditional seed coatings have alleviated the occurrence of this disease to a certain extent, but the effect is still unsatisfactory
Moreover, most of the corn seed coating agents currently used still use carbofuran as the main insecticide, which is a highly toxic pesticide, and the state has restricted its production and use

Abstract

The invention discloses a suspended seed coating for preventing and curing corn smut and a preparation method thereof. The suspended seed coating for preventing and curing corn smut is characterized by being prepared from the following raw materials in percentage by weight: 3.0-7.0% of imidacloprid, 7.0-12.0% of thiram, 0.2-0.6% of diniconazole, 1.5-2.5% of wetting dispersant, 0.5-1.5% of thickening agent, 2.0-6.0% of antifreezing agent, 0.1-0.3% of preservative, 2.0-6.0% of film-forming agent, 3.0-7.0% of warning colouration, 1.0-5.0% of microelements and the balance of water. The suspended seed coating disclosed by the invention is free of harmful effect on the emergence of seedlings and growth of corn, medicine is wrapped around seeds in a concentrated manner, and the medicine is slowly released. The average control effect for corn underground insects is 77.5%-83.5%, the control effect for head smut is 81.7%-88.4%, and the average growth rate is 16.4%-22.6%.

Description

technical field [0001] The invention relates to a corn seed treatment agent. Background technique [0002] With the development of my country's corn seed industry, the area of ​​corn seed production is expanding year by year, and it is difficult to rotate crops and stubble, resulting in an upward trend of corn head smut, which affects the healthy development of the seed industry. The effective way to solve corn head smut is to use the seed coating agent to prevent and control the disease. The seed coating agent is used before sowing to realize concealed application, and can comprehensively prevent and control plant diseases and insect pests at the seedling stage, achieve production maintenance and increase, and have significant economic and ecological benefits. . The principle of action is that the seed coating agent absorbs water and swells in the soil without being dissolved, and forms a protective barrier around the seeds, allowing the water and air required for normal g...
