Technical Field
The invention relates to the field of pesticides, and particularly relates to a safe and efficient seed treatment agent.
Technical Field
The pesticide is an important agricultural production data and is vital to preventing and controlling diseases and pests, promoting grain and agricultural stable yield and high yield. However, the pesticide consumption is large, and the pesticide application method is not scientific enough, so that the problems of increased production cost, overproof pesticide residue of agricultural products, crop phytotoxicity, environmental pollution and the like are caused. The action scheme is specially designed for promoting the change of agricultural development modes, effectively controlling the usage amount of pesticides, ensuring the safety of agricultural production, the quality safety of agricultural products and the safety of ecological environment, and promoting the sustainable development of agriculture. The pesticide seed coating agent has the characteristics of environmental-friendly dosage form, small dosage, long lasting period, accurate target and the like, and completely conforms to the medication guidelines formulated by the state.
The seed coating agent is used by directly coating the pesticide on the surface of the seed, so that very high requirements on the safety of the agent and the effective components are required. The suspending seed coating agent prepared by simple compounding has certain inhibition on the germination rate of wheat seeds and the root length and plant height of wheat seedlings, particularly the germination of the seeds and the growth of the seedlings are seriously influenced by rainwater and low temperature after sowing, and all the agents containing the components have higher potential safety hazards in the using process.
The cyclodextrin is a group of cyclic oligosaccharides which are obtained by biodegradation of starch and are formed by connecting D- (+) -glucopyranose units through alpha-1, 4 glycosidic bonds, has special structures and properties of hydrophobic inner cavities and hydrophilic outer walls, is in a truncated cone shape in appearance, consists of three main members and respectively contains 6, 7 and 8D- (+) -glucopyranose units, namely alpha cyclodextrin, beta cyclodextrin and gamma cyclodextrin, wherein the beta cyclodextrin is cheap and easy to obtain and is most widely applied.
The authors of the present invention have found that, through a large number of tests and explorations, surprisingly, a suspension seed coating agent prepared by a special processing technology of a proper amount of beta cyclodextrin and rare earth containing lanthanum is not only stable in storage, but also capable of significantly improving the germination rate of wheat seeds, reducing phytotoxicity, promoting plant growth, improving control effect and increasing the yield of wheat per unit area.
