Problems solved by technology

[0004] However, most of the traditional corn seed coating agents commonly used at present are pesticide-type reagents, containing toxic fungicides such as imazalil, turpentine and thiram. These fungicides have toxic accumulation in the soil, which seriously damages the ecological environment and affects human health threat

Abstract

The invention provides a corn seed coating agent which comprises the following raw materials in percentage by weight: 6-10% of plant antimicrobial insectifuge, 12-18% of plant nutrient element, 1-2% of plant growth regulator, 2-4% of glutamic acid, 0.5-2% of film formation assistant, 5-10% of colorant and the balance of water. The invention also provides a preparation method of the corn seed coating agent. The control effects of the seed coating agent for leaf blight and sheath blight of corn are respectively up to 78% above, and the food refusal rate for corn aphid is up to 85%.

Description

technical field [0001] The invention relates to a corn seed coating agent and a preparation method thereof. Background technique [0002] As one of the three major food crops in my country, the planting area of ​​corn has reached 30 million hectares. It has various uses and plays an important role in animal husbandry and industry. Therefore, corn planting has far-reaching significance and influence on national grain production and national economic development. [0003] However, maize production has been disturbed by various diseases for a long time, which poses great constraints and threats to the stable and high yield of maize. The seed coating treatment technology can prevent the invasion of corn soil-borne diseases and ensure the yield of corn, thus opening up a new effective way to solve the problems of corn diseases and yield. [0004] However, most of the traditional corn seed coating agents commonly used at present are pesticide-type reagents, containing toxic fung...
