Problems solved by technology

[0003] However, the common types of existing film-forming oils and film-forming agents have poor spreading performance on the water surface, and the oil film has poor continuity and is easy to break. After the film-forming oil is sprinkled on the liquid surface of the paddy field, the performance of the formed film has no effect on the control effect of the product. There are large ups and downs

Embodiment 1

[0030] Embodiment 1: 2% emamectin film spreading oil

[0031] Formula: emamectin 2kg, xylene 5kg, N,N-dimethylformamide 5kg, nonylphenol oxyethylene ether 4kg, fatty alcohol polyoxyethylene ether 3kg, methyl laurate 3kg, propylene glycol phenyl ether 3kg, butyl ether acetate 5kg, citric acid 0.3kg, ethyl acetate to make up to 100kg.

[0032] Preparation process: In a container with a stirrer, first use the solvent ethyl acetate, N,N-dimethylformamide and xylene to stir and dissolve emamectin, then add the auxiliary nonylphenol polyoxyethylene Ether and fatty alcohol polyoxyethylene ether, and finally add film-forming agents methyl laurate, propylene glycol phenyl ether, butyl ether acetate and citric acid, stir and mix well until transparent, that is, 2% emamectin film development Oil agent.

[0033] According to the same preparation process as in Example 1, the following examples were prepared.

Embodiment 2

[0034] Embodiment 2: 15% Quetiaphos film spreading oil

[0035] Formula: Quetiaphos 15kg, Xylene 8kg, N,N-Dimethylformamide 5kg, Nonylphenoxyethylene Ether 4kg, Fatty Alcohol Polyoxyethylene Ether 3kg, Stearyl Alcohol 3kg, Propylene Glycol Phenyl Ether 3kg, Butyl Ether Acetate 5kg, citric acid 0.3kg, ethyl acetate make up to 100kg.

Embodiment 3

[0036] Embodiment 3: 20% acephate film spreading oil

[0037] Formula: acephate 20kg, xylene 8kg, N,N-dimethylformamide 5kg, nonylphenol oxyethylene ether 4kg, fatty alcohol polyoxyethylene ether 3kg, stearyl alcohol 5kg, propylene glycol phenyl ether 5kg, lemon Acid 0.3kg, ethyl acetate make up to 100kg.

Abstract

The invention discloses a film forming agent of a film developing oil agent, which comprises 0-100 parts by weight of methyl laurate, 0-100 parts by weight of octadecanol, 0-100 parts by weight of propylene glycol phenyl ether and 0-100 parts by weight of butyl ether acetic ester. Compared with the traditional film forming agent, the film forming agent disclosed by the invention is good in film forming effect and wider in generality and is applicable to developing a plurality of film developing oil agent products containing pesticide active ingredients; and the developing performances of drugs in the liquid level of a paddy field are good. The invention further discloses a film developing oil agent containing the film forming agent and a preparation method of the film developing oil agent.

Description

technical field [0001] The invention relates to a novel film-forming oil agent film-forming agent, and also relates to the application of the film-forming agent in the film-expanding oil agent, belonging to the field of pesticides. Background technique [0002] As a pesticide dosage form, film-spreading oil can effectively avoid the problems of low efficiency and poor safety of conventional spraying, and has the characteristics of saving time, labor and safety. The dosage form of film-spreading oil does not need to be diluted with water. It will spread out quickly after being directly sprinkled on the crop water surface to form a uniform film. At the same time, under the action of the additive, the film will go up along the crop stem. Spread and concentrate on the base of aquatic plant stems, so as to achieve effective control of aquatic crop diseases, insect pests and weeds that are difficult to achieve by conventional spraying methods. [0003] However, the common types o...
