Technical Field

The invention relates to the technical field of herbicides, in particular to a herbicide for preventing summer corn diseases, insects and grasses from being sprayed with three kinds of materials and a preparation method thereof.

Background

Compared with traditional grain crops such as rice, wheat and the like, the corn has strong drought tolerance, cold tolerance, barren tolerance and excellent environmental adaptability. The corn has higher nutritive value and is an excellent grain crop. As a high-yield grain crop in china, corn is an important feed source in animal husbandry, aquaculture, and the like, and is one of indispensable raw materials for food, medical care, light industry, chemical industry, and the like. Because the corn resources are extremely rich, cheap and easy to obtain, the corn also has a plurality of biological activities, such as oxidation resistance, tumor resistance, blood sugar reduction, immunity improvement, bacteriostasis, sterilization and the like, and has wide development and application prospects.

In recent years, with the continuous expansion of the dosage and scale of the herbicide for summer corn, the herbicide hazard problem of the summer corn is increasingly prominent due to improper combination, improper use period and improper method of the herbicide, the pesticide and the bactericide. In summer corn spraying, farmers, particularly grain planting cooperatives, family farms and grain planting farmers, usually think that the effect of one-time spraying and three-prevention (or three-prevention) is better for weeding, preventing diseases and insects, and the labor investment is the bottleneck for limiting the development of the planting cooperatives in recent years.
