Agriculture synergist, as well preparation and use method thereof

Abstract

The invention discloses agricultural synergist. The synergist is prepared from tea tree oil and surfactant. The preparation method comprises the following steps: (1) stirring tea tree oil at 40-50 DEGC; (2) adding fatty alcohol-polyoxyethylene ether, and stirring to form a mixed liquid; and (3) adding alkylphenol ethoxylate, and stirring until the alkylphenol ethoxylate and the mixed liquid are completely dissolved to obtain the agricultural synergist. The agricultural synergist has the advantages of high safety, environment friendliness, no residue and no toxicity, and can be used for prolonging the effect of agents and resisting decomposition of ultraviolet ray on the agents. Furthermore, the agricultural synergist has the characteristics of superstrong moisturizing, extending, adhering, penetrating and rain brush resisting, and the effect of preparations can be remarkably synergized after the synergist is mixed with insecticide, bactericide, herbicide and foliar-fertilizer preparations. By applying the agricultural synergist, the pesticide dosage can be reduced, application of chemical pesticide can be reduced, pesticide cost can be reduced for peasants, and the agricultural product quality can be improved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to an agricultural synergist and its preparation method and application method. Background technique [0002] Agricultural synergists are a general term for a class of adjuvants that have no biological activity themselves, but when mixed with pesticides and foliar fertilizer preparations, can greatly increase the toxicity and efficacy of these preparations. At present, the main formulations of pesticides and foliar fertilizers include emulsifiable concentrates, microemulsions, aqueous solutions, water-dispersible granules, suspensions (oil suspension, water suspension, suspension emulsion, dry suspension), wettable powders, and soluble powders. Among the above dosage forms, except oil suspension which has a strong synergistic effect, other dosage forms basically achieve the purpose of agricultural synergy by surfactant and dust electrostatic action, so that pesticides or folia...

AI Technical Summary

Problems solved by technology

Among the above dosage forms, except oil suspension which has a strong synergistic effect, other dosage forms basically achieve the purpose of agricultural synergy through the electrostatic action of surfactants and dust, so that pesticides or foliar fertilizers cannot be fully and effectively used , about 40% to 70% of the liquid medicine cannot effectively adhere to the crops and insects, but flows into the soil, thereby reducing the effect of pesticide use, increasing the cost of pesticide use for farmers, and polluting the environment

[0003] There are currently three types of agricultural synergists on the market: (1) Agricultural synergists based on surfactants: such as the surfactant synergist produced by Sichuan Shufeng Chemical Co., Ltd. ), this type of surfactant agricultural synergist has good wettability and permeability, does not have good adhesion and expansion, and cannot effectively exert the agricultural synergistic function; (2) The dosage form with vegetable oil as the main auxiliary agent— —Oil suspension concentrate, which accounts for 70% of the herbicide field. This type of vegetable oil adjuvant mainly appears in pesticide oil suspension concentrate. The main components are soybean oil and methyl oleate. It has three defects: one is easy to separate The second is that it is easy to decompose, and the third is that it is far inferior to silicone in terms of synergy, especially in terms of permeability and expansibility, it cannot effectively play a synergistic role, and only has certain advantages in adhesion; Silicon-based agricultural synergists: such as Momentive 408, an agricultural organic silicon synergist produced by Jiangxi Tiansheng New Material Co., Ltd., this type of organic silicon agricultural synergist occupies 99% of the market share in the field of pesticide synergists , is popular among farmers for its excellent penetration, development, and expansion. However, with the extensive application and practice of organosilicon synergists, the shortcomings of organosilicon have gradually emerged, mainly in the following aspects: 1. Second, the miscibility is poor, and flocculation reaction easily occurs in the mixed liquid, which reduces the efficacy of the medicine; third, it pollutes fruit surfaces and vegetables, does not decompose after penetrating into plants, and has high residues, polluting crops and the environment
