Embodiment 1

[0020] Embodiment 1: Preparation of the spray aid of the present invention

[0021] In terms of mass percentage, at a constant temperature of 50°C, add 15% nonionic surfactant NP-10 to 80% methylated rapeseed oil and stir for 30 minutes, then add 1.5% azone and stir for 30 minutes, then add 1.5% The trimethoxysilane was stirred for 30 minutes, and finally 0.1% ultraviolet absorber UV-P was added and stirred until transparent, the remainder was made up with rapeseed oil, and it was obtained after filtration.

Embodiment 2

[0022] Embodiment 2: Drug efficacy test

[0023] Test pesticide: 70% propiconazole EC;

[0024] Test spray aid: embodiment 1 spray aid and the spray aid prepared according to the method of embodiment 1, just do not add azone and trimethoxysilane;

[0025] Control object: Brazilian banana leaf spot;

[0026] Environmental conditions: The test site is red loam, flat and sloping land, good water and fertilizer conservation, normal fertilizer and water management, relatively consistent growth, banana plant height of about 2.5 meters, field leaf spot damage;

[0027] Test locations: Qiaotao Village, Meiting, Chengmai County, Hainan Province and Daqiao Town, Huazhou City, Guangdong Province.

[0028] Set up blank control group, test group 1 (70% propiconazole emulsifiable concentrate adds embodiment 1 spray aid), test group 2 (70% propiconazole emulsifiable concentrate adds commercially available certain spray aid), each group area is 50 square meters, Brazil banana 15 plants. U...

Embodiment 3

[0040] Embodiment 3: wet performance detection

[0041] The wetting ability of the spray aid is manifested in that when the surface tension of the spray liquid is lower than that of the plant surface, the spray liquid absorbs moisture on the plant surface, otherwise the spray liquid shrinks and rebounds on the plant surface. The spraying aid of Example 1 used in Example 2 and the spraying aid prepared without adding azone and trimethoxysilane according to the preparation method of Example 1 (referred to as the reference spraying aid) were tested for wetting performance, and the results are shown in Table 4 .

[0042] Table 4 Wetting performance parameter results

[0043] Substance name

[0044] As can be seen from Table 4, the surface tension of the control spray aid is not as good as that of the spray aid of the present invention, but after adding azone and trimethoxysilane, the surface wettability exceeds that of using trimethoxysilane and nitrogen alone. Ketone we...

Abstract

The invention which relates to the pesticide assistant field discloses a spray assistant and a preparation method thereof. The spray assistant of the invention comprises, by mass, 0.5-2.5% of azone, 0.5-2.5% of trimethoxysilane, 77-83% of methylated vegetable oil, 10-15% of a nonionic surfactant NP-1, 0.1% of an ultraviolet ray absorbent UV-P, and the balance vegetable oil. The spray assistant of the invention, which can preserve original advantages of a vegetable oil spray assistant, allows the wetting performance to be improved by adding azone and trimethoxysilane, so a pesticide can efficiently penetrate, the drug effect is improved, application amounts of the spray assistant and the pesticide can be reduced under a same drug effect, and the cost and the pesticide residual are reduced, thereby the spray assistant can be widely applied to the agricultural field.

Description

technical field [0001] The invention relates to the field of pesticide adjuvants, in particular to a spray adjuvant and a preparation method thereof. Background technique [0002] A spray adjuvant is an agent that alters the physical characteristics of the spray solution and aids in the penetration of the active ingredient into the target (e.g. crops, weeds, pests). At present, during the use of pesticides, fertilizers, and sanitary preparations, they mainly act on the target through the spraying process. However, if no spray auxiliaries are added, the effects of pesticides, fertilizers, or sanitary preparations will be poor, and the dosage will be large, which will not only increase the cost , and cause harm to the environment and the applicators. [0003] There are three main types of spray auxiliaries, one is mineral oil auxiliaries, the main materials are engine oil, diesel oil, etc., but the affinity and safety with the target are poor; the other is the auxiliaries com...
