Pesticide mist spray additive similar to hair conditioner and preparation method of spraying pesticide additive

Abstract

The invention relates to a pesticide mist spray additive similar to a hair conditioner and a preparation method of the spraying pesticide additive. The pesticide mist spray additive comprises the following components in percentage by weight: an A-phase component comprising behenyl alcohol and white oil, a B-phase component comprising glycerin, EDTA and a surfactant 1631, a C-phase component comprising Silwet 408, AEO-9, Span-80 and Tween-80, and the balance of white oil. The preparation method comprises the following steps: preparing an A-phase mixture, preparing an AB-phase mixture, preparing an ABC-phase mixture, adding the white oil into the mixture till a constant volume to obtain the final pesticide mist spray additive. The pesticidal adjuvant can effectively improve the efficacy and the duration of a pesticide preparation.

Description

technical field [0001] The invention relates to a hair conditioner-like pesticide spray adjuvant and a preparation method thereof. The pesticide adjuvant is suitable for insecticides, fungicides, herbicides and plant growth regulator pesticides, and belongs to the technical field of pesticide adjuvants. Background technique [0002] According to the inventor's understanding, spray auxiliaries have entered the Chinese market for more than ten years, but the development of adjuvants in China is very slow. The reasons are as follows: (1) Although the application of adjuvants can reduce the amount of pesticide , to reduce the cost of drug use, but the price of pesticide preparations in China is relatively low. Even if the application of adjuvants can reduce costs, it is difficult for farmers to spend an extra amount of money to buy adjuvants. (2) In China, the amount of liquid sprayed per hectare of arable land is too high, which weakens the economic benefits brought by the adju...

Problems solved by technology

[0002] According to the inventor's understanding, spray auxiliaries have entered the Chinese market for more than ten years, but the development of adjuvants in China is very slow. The reasons are as follows: (1) Although the application of adjuvants can reduce the amount of pesticide , to reduce the cost of drug use, but the price of pesticide preparations in China is relatively low. Even if the application of adjuvants can reduce costs, it is difficult for farmers to spend an extra amount of money to buy adjuvants

(2) In China, the amount of liquid sprayed per hectare of arable land is too high, which weakens the economic benefits brought by the adjuvant

The application amount of some auxiliaries is directly proportional to the amount of sprayed liquid. Generally, the adjuvant accounts for 0.125%-1% of the sprayed liquid amount. Due to the existence of such a proportion, a higher sprayed liquid amount naturally increases the amount of aid per hectare. The application cost of the agent

At the same time, sometimes high spray volume will reduce the synergistic effect of additives

(3) There is little research on additives in China, and the variety of additives is single

In the late 1980s and early 1990s, most of the non-ionic surfactant herbicide adjuvants used in my country used ethanol as solvent, such as YZ-901, AA-921, etc., within a certain humidity range, they are harmful to pesticides. synergistic effect, but the synergistic effect is not obvious under drought conditions

In addition, traditional additives are mainly emulsifiable concentrate preparations, and there are often toxic and harmful ingredients in them, causing many disadvantages
