Abstract

The invention relates to a pesticide adjuvant, in particular to a wetting agent for pesticide preparations, a method for preparing the wetting agent and application of the wetting agent to the pesticide preparations. The method for preparing the wetting agent for the pesticide preparations includes steps of adding salicylic acid and potassium hydroxide into a reactor, then adding triethylene tetramine into the reactor drop by drop to obtain intermediate monoamide, adding dehydroabietic acid into the reactor and carrying out a series of reaction to obtain intermediate asymmetric bisamides; adding the intermediate asymmetric bisamides and butanone into the reactor, adding propane suhone into the reactor drop by drop, carrying out suction filtration, repeatedly washing substances in the reactor by the aid of butanone, re-crystallizing the substances, neutralizing the substances by the aid of ethanol solution of alkali, separating white solid from the substances, carrying out suction filtration and drying the white solid under the vacuum condition to obtain the wetting agent for the pesticide preparations. The wetting agent, the method and the application have the advantages that the wetting agent for the pesticide preparations is of an asymmetric structure with the bisamides and bis-sulfonate and is excellent in surface activity, compound property and wetting property, and the pesticide absorption rate can be increased.

Description

technical field [0001] The invention relates to a pesticide adjuvant, in particular to a pesticide formulation wetting agent, a preparation method thereof and an application thereof in pesticide formulations. Background technique [0002] It has been discovered very early that many plants, weeds and pests are not easy to be wetted by water and medicinal liquid, and are not easy to adhere and persist, because their epidermis is often covered with a layer of hydrophobic waxy layer, and the composition, shape, and thickness are different. The conditions of different parts of the same plant in different growth periods are also different, which directly affects the application effect. Researchers found that the main components of waxes are long-chain fatty acids, alcohols, aldehydes, esters, etc., and there are other components such as cyclic terpenes, phenols, sterols, and even carotene in some plant epidermal waxes. [0003] Pesticide wetting agent refers to the substance that...
