Abstract

The invention belongs to the field of pesticide compounding, and specifically relates to a bactericidal composition containing emodin methyl ether and brassin and a preparation method thereof. The active components of the bactericidal composition are emodin methyl ether and brassin, and the weight ratio of brassin to emodin methyl ether is 0.001-0.5:0.1-100. A prominent synergetic effect is generated by compounding emodin methyl ether and brassin according to a certain ratio; the generation of drug resistance is retarded, the residual amount of preparation is little, the growth of crops is promoted, and the bactericidal composition is pollution-free to crops and safe and meets the safety requirements of pesticide preparation. The bactericidal composition has a prominent control effect on diseases such as powdery mildew, gray mold, downy mildew, virus diseases, leaf mold, anthracnose, rust disease, wilt, plague, and the like, and also has a good effect on regulating the growth of crops.

Description

technical field [0001] The invention belongs to the field of pesticide compounding, and in particular relates to a bactericidal composition containing emodin methyl ether and brassinin and a preparation method thereof. Background technique [0002] Emodin is a commonly used active ingredient in traditional Chinese medicine. For example, emodin and emodin in Polygonum have anti-aging, scavenging excessive free radicals and anti-tumor effects. [0003] Brassinolide, also known as brassinolide, is the first sterol compound that has been successfully developed to regulate plant growth. Brassinolide can be isolated from dozens of plants, and it can also be used chemically. method for artificial synthesis. The main physiological functions of brassinolides are: 1. Promote cell division, elongation and growth; 2. Facilitate pollen fertilization and increase fruit setting rate; 3. Increase chlorophyll content and photosynthesis; 4. Enhance the stress resistance of plants. It can be...
