preparation example Construction

[0044] The second aspect of the present invention provides a method for preparing clomazone propargyl clomazone · saponin · clomazone EC, the preparation steps comprising:

[0045] According to the formula amount, add solvent and active substance into the reaction kettle, stir until the active substance is completely dissolved, then add epichlorohydrin and triphenyl phosphate in turn, continue to stir and mix evenly, emulsifier, take a sample to analyze the content, and let it stand after passing the test , filtering, packaging, storage.

Embodiment 1

[0048] This example provides a kind of propargyl clomazone · clomazone · clomazone emulsifiable concentrate, calculated by weight percentage, comprising 5% propargyl clomazone, 20% clomazone, and 8% clomazone; The emulsifier is 15%, epichlorohydrin 2%, triphenyl phosphate 2%, and the solvent makes up the balance to 100%.

[0049] The emulsifier is calcium dodecylbenzenesulfonate and castor oil polyoxyethylene ether; the weight ratio of calcium dodecylbenzenesulfonate and castor oil polyoxyethylene ether is 1:1.

[0050] The castor oil polyoxyethylene ether was purchased from Haian Petrochemical in Jiangsu Province, and the model was EL-30. The calcium dodecylbenzenesulfonate is 60% branched chain calcium dodecylbenzenesulfonate octanol solution anhydrous calcium salt, purchased from Handan Xindiya Chemical Co., Ltd., the model is 506X.

[0051] The solvent is first-grade soybean oil and sec-butyl acetate, and the weight ratio of the first-grade soybean oil and sec-butyl aceta...

Embodiment 2

[0055] A kind of propargyl clomazone · sapylphos · clomazone emulsifiable concentrate, the specific implementation method is the same as that of Example 1. The difference is that calcium dodecylbenzenesulfonate is replaced by 50% branched / linear calcium dodecylbenzenesulfonate alkane solution anhydrous calcium salt, purchased from Handan Xindia Chemical Co., Ltd., the model is 505A.

The present invention solves the problems of easy decomposition of active ingredients in existing pesticides and poor long-term storage stability of emulsions through a kind of propargyl clomazone·sapylphos-clomazone EC and its preparation method, and prepares a stable Strong, low decomposition rate, excellent herbicidal emulsifiable concentrate. The invention has simple process, strong practicability and broad application prospect.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a propargyl clomazone-sapylphos-clomazone emulsifiable concentrate and a preparation method thereof. Background technique [0002] Pesticides refer to chemical agents used in agriculture to prevent and control plant diseases and insect pests and regulate plant growth. Widely used in agricultural, forestry and animal husbandry production, environmental and household sanitation, pest control and epidemic prevention, industrial product mildew and moth prevention, etc. There are many varieties of pesticides, which can be mainly divided into insecticides, acaricides, rodenticides, nematocides, molluscicides, fungicides, herbicides, plant growth regulators, etc. according to their uses. [0003] Pesticides used to kill or control the growth of weeds are called herbicides. The beginning of chemical weeding in farmland can be traced back to the end of the 19th century. When preventing and con...
