Description
Technical Field
The invention relates to the field of agriculture, and particularly relates to an agricultural synergistic auxiliary for wolfberry seed oil and a preparation method and application thereof.
Background
The agricultural synergist has no biological activity, but can greatly improve the toxicity and the efficacy of the pesticide when being mixed with a certain pesticide and a foliar fertilizer. At present, main dosage forms in pesticide and foliar fertilizer preparations comprise emulsifiable solution, microemulsion, water aqua, water dispersible granules, suspending agents (oil suspension, water suspension, suspension emulsion, dry suspension), wettable powder, soluble powder and the like, wherein the oil suspension has stronger synergism, and other dosage forms basically solve the agricultural synergism by the action of surfactant and dust static electricity, so that the effective utilization rate of the pesticide can not be far reached, when the foliar fertilizer is sprayed on crops, 40-70% of liquid medicine is not effectively adhered to the crops and insects and flows into soil, thereby reducing the using effect of the pesticide, increasing the pesticide cost of farmers and polluting the environment. During the spraying process, farmers need to add agricultural synergist. Agricultural synergists on the market are divided into three types: (1) an agricultural synergist based on a surfactant; the surfactant agricultural synergist has good wettability and permeability, does not have good adhesion and expansion effects, and cannot effectively exert an agricultural synergistic function; (2) the oil suspending agent which is a formulation taking vegetable oil as a main auxiliary agent occupies 70 percent of the field of herbicides; the vegetable oil auxiliary agent mainly appears in the pesticide oil suspending agent, and the main components are soybean oil and methyl oleate, which have two defects: firstly, the film is easy to delaminate, secondly, the film is easy to decompose, thirdly, the film is far inferior to organosilicon in synergistic effect, and particularly, the film cannot effectively play a synergistic effect in permeability and expansibility. Only have certain advantages in adhesion; (3) an agricultural synergist based on organic silicon; the organic silicon agricultural synergist occupies 99 percent of the market share in the field of pesticide synergists, and is popular with farmers due to excellent penetration, spread and expansion. However, with the extensive use and practice of silicone synergists, the drawbacks of silicone slowly manifest themselves, with major surfaces in the following areas: firstly, the problem of phytotoxicity is serious; secondly, the mixing property is poor, flocculation reaction is easy to occur in the mixed solution, and the drug effect is reduced; thirdly, fruit surfaces and vegetables are polluted, and the fruits and the vegetables are not decomposed after penetrating into plant bodies, so that the residue is high, and the agricultural effect and the environment are polluted.
Based on the factors, through a large number of tests and applications in nearly five years, the medlar seed oil agricultural synergistic additive is an organic silicon upgrading substitute, has the strong synergistic advantage of organic silicon, avoids the problems of organic silicon phytotoxicity, pesticide effect and residue, solves the great problems of agricultural synergistic agents in China, and is environment-friendly, safe and remarkable in synergism. Meanwhile, the medlar seed oil agricultural synergistic additive is sprayed by 1000 times singly, has outstanding control effects on red spiders, aphids, pear psyllids and trialeurodes vaporariorum, and is environment-friendly, safe, nontoxic, residue-free and permanently resistant to insect pests.
