Problems solved by technology

However, in southern China, such as Fujian, Guangdong and other places, due to the high annual average temperature, the secretion of masson pine pine resin is vigorous, which will cause the injection hole of the injector to be blocked by rosin when using the desiccating agent, causing the liquid The phenomenon that it cannot be injected into the tree occurs, and the dried pesticide solution is released and decomposed before the trunk lesions, so that the active ingredients cannot enter the trunk smoothly, the drug effect cannot be fully exerted, and the ideal control effect cannot be achieved. Therefore, a dry pesticide injection is needed to help agent to improve the deficiencies of the existing technology

Abstract

The invention relates to the technical field of trunk injection agents, in particular to a research, development and preparation method of a trunk injection pesticide adjuvant. The adjuvant comprises the following raw materials in percentage by mass: an active compound, a synergist, a penetrant, a modification inhibitor and a cosolvent. The synergist is a perfluoroalkane organic fluorine compound. The penetrant is formed by mixing a polyoxyethylene ether compound with one or more of secondary alkyl sodium sulfonate, sodium dioctyl sulfosuccinate and sodium alkyl naphthalene sulfonate. The modified inhibitor comprises the following raw materials in percentage: an anti-photolysis agent, an antioxidant, a thickening agent and water. The modified inhibitor can increase the system viscosity of the trunk injection pesticide auxiliary agent, reduce the decomposition and release rate of the emamectin benzoate under ultraviolet light. The modified inhibitor can reduce the decomposition rate of the emamectin benzoate, so that the emamectin benzoate flows for a longer time in the trunk, the pesticide activity of the emamectin benzoate is improved, and the emamectin benzoate still has an efficient killing effect on pine wood nematodes after penetrating through rosin.

Description

technical field [0001] The invention relates to the technical field of dry injection agents, in particular to a research, development and preparation method of dry injection pesticide adjuvants. Background technique [0002] Pine wood nematode disease, also known as pine wilt disease, is a devastating epidemic disease of pine forests. It has the characteristics of rapid spread, difficult control, rapid onset, and severe damage. It is called "the cancer of pine trees". In my country, pine wood nematode disease is mainly carried by adults of Monochamus alternatus, and spreads the disease through activities such as feeding, supplementing nutrition and laying eggs. The pine xylophilus that invades the pine tree reproduces and moves in the tree, the number grows rapidly and in large numbers, and gradually distributes to the whole tree, secretes cellulase and other toxic substances, destroys the parenchyma cells and epithelial cells of the resin duct, disturbs the metabolism of th...
