Composite type corn seed coating agent

Abstract

The invention provides a composite corn seed coating agent which comprises the following raw materials according to the mass percent: 4 percent to 7 percent of chlorpyrifos, 2 percent to 4 percent of dniconazole, 0.1 percent to 0.5 percent of compound sdium ntrophenolate, 1 percent to 1.5 percent of film-forming agent, 1 percent to 1.5 percent of dispersant, 2 percent to 3 percent of calcium dodecyl benzene sulfonate, 1 percent to 1.5 percent of preservative agent, 1 percent to 4 percent of antifreeze agent, 5 percent to 10 percent of bulking agent, 1 percent to 1.5 percent of alert color andthe rest of water. The seed coating agent is mainly used for seed coating before the corn sowing, can effectively control the maize head smut and the soil insects, also can promote the breeding of roots and healthy seedlings, enhance the anti-adversity of the crops and improves the yield of the corns. The test result shows that the control effect of the seed coating agent to the maize head smut reaches 87.65 percent and 90.53 percent, and the control effect of the seed coating agent to the soil insects of the corns reaches 76.84 percent and 85.69 percent, and the yield increasing rate reaches7.6-10.2 percent.

Description

technical field [0001] The invention relates to a seed coating agent, in particular to a composite corn seed coating agent. The seed coating agent can effectively prevent and control corn head smut and underground pests, promote roots and seedlings, enhance crop stress resistance, and increase yield. Background technique [0002] In agricultural research and production, seed pesticide treatment is one of the most economical and convenient methods to prevent and control underground pests and crop soil-borne and seed-borne diseases. Seed coating technology is a new seed treatment technology widely used in the world developed on the basis of traditional seed soaking or seed dressing technology. The comprehensive supporting technology integrating pesticide, plant protection, chemical industry, machinery and other disciplines by means of machinery is an organic combination of modern seed processing, standardization of seed quality and integrated pest control in the field.

AI Technical Summary

Problems solved by technology

[0004] Since the research and development of seed coating agents in my country started relatively late, and the production technology and detection level were still relatively backward, after a large number of comparative experiments and observation studies, it was found that there are still some problems in the development and application of seed coating agents in my country: on the composition of active ingredients, The drug formula is single, the pertinence is poor, the formula is not reasonable, and the actual application effect is not ideal; the film forming technology is not mature enough, the shedding rate is high, and it is easy to cause phytotoxicity, etc.
