A kind of novel corn seed coating agent and preparation method thereof

Abstract

The invention discloses a novel corn seed coating agent and a manufacturing method thereof. The seed coating agent contains 2% of tebuconazole, 8% of thiram, 8% of chlorpyrifos, 5% of bentonite, and the rest are micro-fertilizer, plant growth regulator, auxiliary agent and water. The manufacturing method step of this seed coating agent is: take glass beads as sanding medium, the particle diameter of glass beads is 2~5mm, the ratio of selected raw material and medium in the above-mentioned seed coating agent formula is 1: 2; The original drug, filler and wetting and dispersing agent in the seed coating formulation, add 50% of the water consumption; use a high-shear emulsifier to shear at a speed of 4000r / min for 20min; sand mill for 2.5h; and another 50% of water Thin film-forming agent, thickener and other additives described in the present invention, after treating to dissolve completely, add in the grinder, continue to grind 0.5h; Filter out product. The seed coating agent has good effect of disease prevention and seedling preservation, and the manufacturing method has high recovery rate and saves cost.

Description

technical field [0001] The invention relates to a seed coating agent, in particular to a novel corn seed coating agent and a manufacturing method thereof. Background technique [0002] With the rapid development of the corn seed production industry in the Hexi Corridor, the area of ​​corn seed production in Hexi has continued to expand, and the phenomenon of continuous cropping and heavy cropping has become more serious, resulting in the occurrence of corn pests and diseases increasing year by year. The application of corn seed coating agent for coating treatment is the key to the prevention and control of corn seedling pests and diseases One of the effective measures that occurred. [0003] Corn seed coating agent is made of insecticides, fungicides, compound fertilizers, trace elements, plant growth regulators, slow-release agents, film-forming agents, etc. through advanced production technology, and can be directly or diluted and wrapped in seeds On the surface, a pestic...

AI Technical Summary

Problems solved by technology

[0004] At present, the seed coating agents used for corn coating in the Hexi Corridor are all imported from other places. These seed coating agents are highly toxic, have low drug efficacy, and are not highly targeted. They lack effective prevention and control of corn seedling pests and diseases. This poses a greater potential safety hazard, and also increases the cost of corn seed production

[0005] In addition, the recovery rate is low during the production and processing of seed coatings, which not only causes waste of raw materials, but also increases production costs
