Problems solved by technology

[0005] The extraction process of chelerythrine has been studied for many years. At present, the extraction process of chelerythrine is mature, but the research on its dosage form is less or relatively lagging behind, and more emulsifiable concentrate formulations are used in current agricultural production. do not give new fixed point

Embodiment 1

[0020] [Example 1] Concentration content is 0.3% chelerythrine water emulsion, and the consumption of each component is calculated by weight:

[0021] Chelidonium 0.3kg Ethyl acetate 5kg Nonylphenol 8kg

[0022] Lauryl Alcohol 2kg Xanthan Gum 0.2kg Sodium Chloride 2kg

[0023] Silicone 0.1kg potassium dihydrogen phosphate 2kg water 80.4kg

[0024] Preparation

[0025] 1. According to the weight of the above components, mix chelerythrine, ethyl acetate, nonylphenol and dodecanol together to dissolve into a uniform oil phase;

[0026] 2. Mix water, sodium chloride, xanthan gum, silicone, and potassium dihydrogen phosphate together according to the above weight, mix well, and dissolve into the water phase; under high-speed shear force stirring, add the water phase to the oil phase, Shear and stir until the average fineness is 0.7-20μm, and finally form a water emulsion. According to the water-emulsion quality control index, the product quality inspection of active ingredients...

Embodiment 2

[0027] [Example 2] Concentration content is 5% chelerythrine aqueous emulsion, and the consumption of each component is calculated by weight:

[0028] Chelidonium 5kg Ethanol 18kg Nonylphenol 12kg

[0029] Isobutanol 4kg Magnesium Aluminum Silicate 0.5kg Urea 2kg

[0030] Polyglycerin 0.4kg Ammonia 1.5kg Water 56.6kg

[0031] Preparation

Abstract

The invention discloses a biological antimicrobial chelerythrine aqueous emulsion and a preparation method of the biological antimicrobial chelerythrine aqueous emulsion. The biological antimicrobial chelerythrine aqueous emulsion is mainly prepared from chelerythrine, ethyl acetate, nonyl phenol and dodecanol according to a certain proportion by weight. The biological antimicrobial chelerythrine aqueous emulsion has efficient sterilization and disease prevention performances, and is wide in application range and good in effect when used for preventing and controlling crop diseases and pests.

Description

technical field [0001] The invention relates to a biological pesticide, in particular to a biological bactericide chelerythrine aqueous emulsion and a preparation method thereof. Background technique [0002] Most of the fungicides currently produced in my country are old varieties such as organophosphorus, substituted benzenes, organosulfurs, benzimidazoles and triazoles. Due to the long-term use of these traditional old varieties, many varieties have developed high resistance, and they are only effective when used in large doses, resulting in excessive pesticide residues in agricultural products. Especially some large-tonnage varieties currently on the market, such as triadimefon, carbendazim, etc., have serious resistance problems, and the control effect is poor or basically ineffective, which can no longer meet the market demand. Therefore, it is imperative to vigorously develop new varieties and new formulations of highly efficient and safe biocides. [0003] Chelidon...
