Problems solved by technology

After being in contact with microorganisms, difenazim can quickly and irreversibly inhibit their growth, leading to the death of microbial cells, so it has a strong inhibitory and killing effect on common bacteria, fungi, algae, etc. Spot bacteria such as Gracilicutes, Xanthomonas, etc. have low killing efficiency and cannot be killed basically, and such bacteria will be brought to the rice, so that the harvested seeds will also carry similar bacteria, which will affect the planting of the next season

Embodiment 1

[0016] The original drug of diabendazim and the extract of cat's whiskers are taken, added to sterile water and a small amount of surfactant is added, and after ultrasonic treatment, the mother liquors are prepared respectively. According to the purpose of mixing, set the ratio of multiple groups of medicines, 1:9, 1:4, 3:7, 2:3, 1:1, 3:2, 7:3, 4:1, 9:1, each ratio Both are the mass ratios of the active ingredients of the two medicaments.

[0017] Among them, the root of the cat's whiskers is used as the plant source, and the ethanol heat reflux method is used to extract for 3-5 hours, and the obtained extract is flashed and concentrated to 0.1-0.15 times the original volume at 60-70 ° C by using a vacuum film concentration device, and then The concentrated solution is vacuum-dried at 50-60° C. into a dry powder to obtain the cat's whiskers extract.

Abstract

The invention belongs to the technical field of bactericides and discloses an anilazine and clerodendranthus spicatus extract containing bactericidal composition.The anilazine and clerodendranthus spicatus extract containing bactericidal composition comprises effective components including anilazine and clerodendranthus spicatus extract in a weight ratio of 1:10-10:1.A method for extracting the clerodendranthus spicatus extract includes: extracting clerodendranthus spicatus for 3-5 hours according to an ethanol hot reflux method, using a vacuum thin film concentration device for flash concentration of the extracted liquid at 60-70 DEG C, and subjecting concentrated liquid to vacuum drying to obtain dry powder.By compounding of the clerodendranthus spicatus extract and the anilazine, owing to own advantages of the clerodendranthus spicatus extract, the bactericidal composition can infiltrate into rice to kill bacteria in a bacterial process, and since the clerodendranthus spicatus extract is natural plant extract, residues and pollutions are avoided, and efficiency of anilazine are further enhanced.The anilazine and clerodendranthus spicatus extract containing bactericidal composition is excellent in performance of killing uncommon bacteria such as Xanthomonas oryzae pv.oryzicola including xanthomonas, gracilicutes and the like and is above 90% in bactericide effect.

Description

technical field [0001] The invention belongs to the technical field of bactericides, and in particular relates to a bactericidal composition containing diclofenac and cat's whiskers extract. Background technique [0002] The prevention and control of crop diseases accounts for a large proportion of agricultural production costs. With the development of science and technology, a large number of fungicides continue to emerge, and their efficacy is getting higher and higher. In actual use, many fungicides have strong specificity and a narrow target range, which is difficult to meet the requirements of control and requires the mixed use of multiple agents. However, the technical content of pesticide mixing is relatively high, and the mixed use of pesticides by farmers often leads to decreased efficacy and phytotoxicity. Therefore, it is necessary to make a fungicide with good compound effect into a compound agent, which has achieved the purpose of simple and efficient disease p...
