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
At the end of the 1980s and the beginning of the 1990s, most of the non-ionic surfactant herbicide adjuvants used in my country used ethanol as a solvent, such as YZ-901, AA-921, etc., within a certain humidity range, which 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

Embodiment 1

[0037] Example 1 Preparation of Pesticide Spray Auxiliary

[0038] The pesticide spray adjuvant is composed of the following components by weight percentage: A phase component: 1.0-2.0% behenyl alcohol, 8.0-10% white oil; B phase component: 2.0-3.0% glycerin, 0.05-0.06% ethylene glycol Disodium amine tetraacetate, 1.6-2.0% Surfactant 1631; Phase C components: 10-12% Silwet 408, 2.0-3.0% AEO-9, 2.0-3.0% Span-80, 4.0-6.0% Tween-80 ; The balance is white oil.

[0039] Docosanol adopts cosmetic grade behenyl alcohol, such as original BASF behenyl alcohol Lanette 22. The white oil adopts cosmetic grade white oil. Span-80, Tween-80: Tianjin Kemiou Chemical Reagent Co., Ltd. Silwet408: Changzhou Jinrun Chemical Co., Ltd. AEO-9: Shanghai Wenhua Chemical Pigment Co., Ltd.

[0040] Concrete preparation steps are as follows:

[0041] The first step is to mix the components of phase A and stir evenly at 75°C-80°C;

[0042] The second step is to mix the B phase components and heat a...

Embodiment 2

[0053] Embodiment 2 The use of embodiment 1 pesticide spray adjuvant

[0054] Take chlorantraniliprole 20% suspension concentrate and acetamiprid 40% water-dispersible granules respectively; dilute chlorantraniliprole 4000 times, acetamiprid 8000 times, make chlorantraniliprole and acetamiprid The concentration reached 50mg / kg. Add the pesticide spraying auxiliaries prepared in each case of Example 1 into the pesticide preparation at a weight percentage of 0.03-0.10%, and then apply after mixing.

[0055] See Table 3 for the specific preparation weight percentages of each case.

[0056] Table 3 Preparation ratio of each case

[0057] the case

Embodiment 3

[0058] Example 3 The use effect experiment of Example 1 Case 3

[0059] The pesticide preparation used was 60% monosultap, and the application rate was 80 g / mu. After the pesticide preparation was treated, the efficacy experiment of controlling rice leaf roller was carried out.

[0060] The treatment methods are as follows: (1) direct application without additives. (2) Apply after adding common adjuvant AEO-9. (3) Apply after adding the pesticide spraying adjuvant prepared in Example 1 Case 3 by 0.10% by weight.

[0061] The drug efficacy test results are shown in Table 4.

[0062] Table 4 Results of pesticide efficacy experiments on controlling rice leaf roller

[0063]

[0064] It can be seen from the results that the control effect and persistence of the pesticide spray adjuvant prepared in Example 1 and Case 3 are significantly better than those of no adjuvant and common adjuvant treatment.

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.
