Problems solved by technology

However, the long-term use of triazole chemical fungicides in large quantities is likely to cause harm to water sources, soil, natural enemies of pests, and human health.
In addition, the control effect of microbial fungicides is relatively slow and is easily restricted by the temperature and humidity of the farmland

Embodiment 1

[0024] Such as image 3 .In order to clarify the degree of inhibition of different concentrations of tannin on Aspergillus oryzae, the plaque size of Aspergillus oryzae was measured under different concentrations of tannin. A low-concentration tannin aqueous solution (0.1 mg / ml) was selected for experimentation, and the results showed that 0.1 mg / ml tannin had basically no inhibitory effect on Aspergillus oryzae.

Embodiment 2

[0026] Such as image 3 .In order to clarify the degree of inhibition of different concentrations of tannin on Aspergillus oryzae, the plaque size of Aspergillus oryzae was measured under different concentrations of tannin. An aqueous solution of tannin (0.2 mg / ml) with a moderate concentration was selected for experiments, and the results showed that the inhibitory effect of 0.2 mg / ml tannin on Aspergillus oryzae could reach 45%.

Embodiment 3

[0028] Such as image 3 .In order to clarify the degree of inhibition of different concentrations of tannin on Aspergillus oryzae, the plaque size of Aspergillus oryzae was measured under different concentrations of tannin. An aqueous solution of 0.3 mg / ml tannin with a higher concentration was selected for experiments, and the results showed that the inhibitory effect of 0.3 mg / ml tannin on Aspergillus oryzae could reach 95%.

Abstract

The invention relates to the field of pesticides, and provides a pesticide for preventing and treating rice false smut. The pesticide is characterized in that the mass ratio of tannin to water in thepesticide is 1:2. The tannin can effectively inhibit growth of ustilaginoidea virens, so that the tannin can be used for controlling occurrence of rice false smut, improving the yield of rice, protecting the environment, and reducing pollution of the ustilaginoidea virens toxin to rice during production, so that safety of people and livestock is protected.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a pesticide for preventing and treating rice false smut. Background technique [0002] Tannin is a natural polyphenolic substance produced by a class of higher plants, which widely exists in leaves, fruits, roots and bark of plants. The polyphenolic hydroxyl chemical structure of tannin makes tannin exhibit various biological activities such as strong anti-oxidation, anti-virus, anti-tumor. Therefore, tannin is widely used in multidisciplinary fields such as medicine, food, agriculture, materials, and chemical industry. Recent studies have found that tannins have strong antibacterial activity against various microorganisms such as bacteria and fungi. Aboh et al. measured the inhibitory effects of tannin extracts on Candida albicans, Trichophyton, and Aspergillus fumigatus by agar diffusion method and micro broth dilution method. The results showed that the minimum inhibitory concentra...
