Problems solved by technology

Although the safety of high-boiling point (C10-C14) heavy aromatic solvents has been improved and the toxicity to humans has been reduced, the problem of environmental degradation has not been solved, the threat to the ecological environment still exists, and its environmental protection performance has not yet met the requirements.
Dibasic acid ester (DBE) is a mixture of dibasic acid esters. At present, there are problems of high production cost and price, which directly limit the application in the production of pesticide preparations in my country.
Traditional esterified vegetable oil is the esterification product of edible vegetable oil, which has the problem of competing with others for edible oil, and the price is also relatively high. Moreover, most vegetable oil solvents such as corn oil esters, soybean oil esters, etc. are compatible with the active ingredients of pesticides. Poor solubility, difficult to match with existing agricultural emulsifiers, which also limits its production and application in pesticide formulations
Although monoterpenoids such as α-pinene, β-pinene, dipentene, etc. have good solubility for pesticides, they are expensive, have low flash points, and have poor adhesion to the surfaces of plants and harmful organisms to be controlled. ideal

Abstract

The invention provides an agricultural combination solvent which comprises a terpenoid and C8-C18 fatty acid esters. The agricultural combination solvent has good compatibility with pesticides, is safe and environment-friendly, has good biodegradation, has no pollution, has low freezing point and high flash point, and is safe and reliable in production, storage, transportation and use. The agricultural combination solvent can be applied in insecticides, herbicides or / and plant growth regulators.

Description

technical field [0001] The invention belongs to the field of pesticide preparations, in particular to an agricultural combination solvent and its application. Background technique [0002] For a long time, aromatic hydrocarbon (including benzene, toluene, xylene, etc.) organic solvents have been widely used in the production of pesticide liquid preparations. With the use of emulsifiable concentrate every year, a large amount of aromatic hydrocarbon organic solvents enter the agricultural ecological environment, which not only causes waste of petroleum resources, but also Bring serious food safety and environmental pollution risks. Replacing light aromatic hydrocarbon solvents represented by "triphenyl" has become an inevitable trend in the development of pesticide formulations in the world, and it is also in line with the main orientation of national industrial planning and industrial policies in recent years. Therefore, there is a continuous demand for green solvents in th...
