Description
Technical Field
The invention belongs to the field of agricultural seed treatment agents, and particularly relates to an environment-friendly peanut seed coating agent and a preparation method thereof.
Background
Peanuts are annual herbaceous plants of the genus Arachis in the family Leguminosae, are important oil crops, and are planted all over the country. Peanuts have good effects of promoting growth, resisting aging, stopping bleeding, generating blood and the like, and are also called as perennial fruits. Due to the influence of factors such as poor planting modes of continuous cropping of peanuts and the like, diseases and insect pests are increasingly serious in peanut planting, and the diseases and insect pests in seedling stage become one of the main factors influencing the peanut yield. The main diseases of the peanut in the seedling stage comprise stem rot, damping off, root rot, root mold, crown rot, bacterial wilt and the like, wherein the stem rot and the root rot are the two diseases which influence the yield most in the seedling stage. The diseases of the peanut in the seedling stage occur all year round, mainly damage root systems and leaves, often cause thinning and rotting of the roots, green and wilting of the leaves in a short time, generally reduce the yield by 15 to 30 percent, and even stop the yield. The soil insects are main insects influencing peanut germination, fruit setting, pod formation, yield and quality, and the main control objects are grubs. The grub is larva of the scarab, is the largest pest on the peanuts at present, and seriously affects the yield from sowing to harvesting in the pest period.
Seed coating is a technology for promoting agricultural production increase and harvest development in the last 30 th century, and is commonly applied in developed countries. The seed coating uses seeds as a carrier, is adhered to the seeds by the aid of a film-forming agent, is solidified into a uniform medicine film, is expanded when meeting water in soil and is ventilated without being dissolved, so that the seeds normally germinate, the pesticide and fertilizer are gradually released without toxic and harmful effects on the germination and growth of crops, and the seed coating has water permeability and air permeability and does not influence the life and respiration of the seeds. The seed coating has the obvious effects of killing underground pests, preventing and treating seed bacteria and seedling diseases, improving the germination rate of seeds, reducing the use amount of the seeds, promoting the healthy growth of seedlings, improving the quality of crops, increasing the yield and the like. Seed coating is listed as an agricultural technical project which is mainly popularized in China.
In recent years, some disease-preventing and insect-preventing peanut seed coating agents are developed domestically, and certain effects are achieved. However, the products have certain limitations, such as single function, low application range, high toxicity and the like, and influence the popularization and the application of the peanut seed coating agent.
In order to meet the requirements of current agricultural production and environmental protection, highly toxic and high-residue pesticides are continuously forbidden, and an environment-friendly peanut seed coating agent with low toxicity and high efficiency for preventing and treating peanut seedling diseases and insect pests is required to be developed in the current production.
The spinetoram suspending agent is a spinosyn biological source pesticide, and a new generation of high-efficiency, broad-spectrum, low-toxicity and environment-friendly pesticide. Its advantages are high quick acting, long acting period, high safety, unique insecticiding mechanism and no cross resistance to existing insecticide.
Azadirachtin is a tetracyclic triterpene compound, and is distributed in branches, leaves, kernels, seed shells and barks of neem trees. Azadirachtin inhibits protein synthesis, prevents cell division and affects hormone secretion. The safety of the medicine is greatly researched in foreign countries, and the result shows that the medicine is safe for mammals. Azadirachtin can prevent and control more than 200 kinds of agricultural, forestry, storage and sanitary pests, and is a widely-recognized pesticide in the world at present, which has the advantages of broad spectrum, high efficiency, low toxicity, easy degradation and no residue.
The shenqinmycin is a new pesticide in China which has independent intellectual property rights, can effectively control various fungal diseases and bacterial diseases, and has the characteristics of high efficiency, low toxicity, broad spectrum, no public nuisance and good environmental compatibility. It is an agricultural antibiotic secreted by pseudomonas fluorescens through biological fermentation and culture, can effectively control various fungi and bacterial diseases of crops, and can also promote the growth of plants.
The zhongshengmycin is a novel agricultural antibiotic, is produced by Hainan variety of Streptomyces lavendulae, and belongs to N-glycoside alkaline water-soluble substances. The processed preparation form of the strain is a protective bactericide with wider bactericidal spectrum and has the functions of contact killing and penetration. The zhongshengmycin has high activity on bacterial diseases and partial fungal diseases of crops, and has a certain yield increasing effect.
