Description
Technical Field
The invention relates to the field of pesticide additives, in particular to a pesticide synergistic additive and a preparation method thereof.
Background
At present, the difficulty and the investment for developing new drugs are gradually increased, and how to improve the effect of the existing drugs is always the key point of research. The low effective utilization rate of the pesticide is a main factor for reducing the effect of the pesticide, and the main factor for causing the low effective utilization rate of the pesticide has two aspects: on one hand, the pesticide drops are difficult to wet on the surface of the target and bounce and roll off, so that the loss rate of the pesticide is high, and on the other hand, the pesticide agent is difficult to permeate into the target or target plants to reach effective lethal concentration, so that the utilization rate of the pesticide is low.
Researches find that a compact wax layer exists on the surfaces of plant leaf surfaces and harmful organisms, and is a main factor causing pesticide liquid drops to slide and permeate on the target surface without being easily wetted. In response to the above problems, researchers have developed functional aids to improve the wetting and permeation properties of medical solutions.
The vegetable oil synergist is a synergistic aid with the highest development and utilization rate, and is composed of vegetable oil and a surfactant, so that the wetting and adhesion performance of a liquid medicine on a target or a target plant can be improved, the drying time is prolonged, and meanwhile, the vegetable oil can dissolve a wax layer on the surface of the target and a target crop, so that the permeability of the medicine on the target or the target plant can be improved. However, vegetable oils have the following disadvantages: the cost of part of vegetable oil is high, such as sunflower oil, corn oil and the like; secondly, the density of the vegetable oil is low, and the deposition of the fog drops is not facilitated in the drifting process of the fog drops; thirdly, the vegetable oil has complex and variable components, the performance of the vegetable oil is not as stable as that of an organic solvent, and the vegetable oil is easily influenced by plants from different sources and storage and transportation conditions, so that the performance of the product is unstable, and the popularization and the application of the vegetable oil additive are limited to a certain extent.

Preferably, the weight ratio of the vegetable oil or the esterified vegetable oil, the glycol diacetate, the emulsifier and the penetrant is 60-100:20-70:20-50: 1-4.
Preferably, the emulsifier is an anionic surfactant and/or a nonionic surfactant.
Further, the emulsifier is selected from one or more of alkylphenol ethoxylates, styrylphenol polyoxyethylene ether, alkylaryl phenol polyoxyethylene ether phosphate, castor oil polyoxyethylene ether, alkylbenzene sulfonate, di-sec-octyl maleate sodium sulfonate, fatty alcohol polyoxyethylene ether, sorbitan fatty acid polyoxyethylene ether, sodium dodecyl sulfate and calcium dodecyl benzene sulfonate.
Further, the emulsifier is a mixture of castor oil polyoxyethylene ether, fatty alcohol polyoxyethylene ether and calcium dodecyl benzene sulfonate.
Furthermore, the mass ratio of the castor oil polyoxyethylene ether to the fatty alcohol polyoxyethylene ether to the calcium dodecyl benzene sulfonate is 1-200:1-200: 10.
Preferably, the penetrant is oily azone and/or copper rosinate. More preferably oily azone.
