Embodiment 1

[0018] Embodiment 1 The control of rice stripe disease

[0019] Test method: Spray once at the early stage of disease onset, and treat 3 plots for each plot, each plot is 20 square meters. Investigate and count the incidence before and 10 days after the application, randomly sample at 5 points in each plot, investigate the percentage of lesion area on each leaf of the whole plant to the leaf area, and calculate the disease index and control effect.

[0020] Prepare soluble reagents according to the following ratio

[0021] Yebuazole 20%;

[0022] Niclosamide 0.2%;

[0023] Dispersant (lignosulfonic acid) 10%;

[0024] Solvent (dimethylformamide) 87.8%;

[0025] The preparation prepared according to the above ratio was diluted 500 and 1000 times for spraying, and 21% of yebuconazole was used as the control (niclosamide does not have bactericidal effect, the control here is omitted), and the control effect on rice stripe disease was in 83% and 74%. The control effects of t...

Embodiment 2

[0026] Example 2 Prevention and treatment of cabbage horn spot

[0027] Test method: Spray once at the early stage of disease onset, and treat 3 plots for each plot, each plot is 20 square meters. Investigate and count the incidence before and 10 days after the application, randomly sample at 5 points in each plot, investigate the percentage of lesion area on each leaf of the whole plant to the leaf area, and calculate the disease index and control effect.

[0028] Prepare soluble reagents according to the following ratio

[0029] Yebuazole 10%;

[0030] Niclosamide 10%;

[0031] Dispersant (lignosulfonic acid) 10%;

[0032] Solvent (dimethylformamide) 70%;

[0033] The preparation formulated according to the above ratio was diluted 1000 or 2000 times for spraying, and 20% yebuconazole was used as the control (niclosamide does not have bactericidal effect, the control here is omitted), and the control effect on cabbage horn spot was 80% %, 71%, the control effect of the c...

Embodiment 3

[0034] Example 3 Citrus canker

[0035] Test method: Spray once at the early stage of disease onset, and treat 3 plots for each plot, each plot is 20 square meters. Investigate and count the incidence before and 10 days after the application, randomly sample at 5 points in each plot, investigate the percentage of lesion area on each leaf of the whole plant to the leaf area, and calculate the disease index and control effect.

[0036] Prepare soluble reagents according to the following ratio

[0037] Yebuazole 0.1%;

[0038] Niclosamide 10%;

[0039] Dispersant (lignosulfonic acid) 10%;

[0040] Solvent (dimethylformamide) 70%;

[0041] The preparation formulated according to the above ratio was diluted 50 times for spraying, and 10% of euclopyrazole was used as a control (niclosamide does not have bactericidal effect, the comparison here is omitted), and the control effect on citrus was above 65%. The control efficiency can only reach 26%.

Abstract

The invention discloses a composition for preventing and treating agricultural diseases and killing snails. The composition comprises the active components of bismerthiazol and niclosamide. The composition is prepared through binary mixing of other pesticide varieties, such as the bismerthiazol and niclosamide. The composition is applied to prevention and treatment of agricultural bacterial diseases, and the bacterial control performance can be greatly improved. The two effective components in the composition have a synergistic effect, the allowable application amount is reduced, the prevention and treatment effect is more lasting; the harmful bacteria of plants are better controlled through application for one time or a few of times, and the possible application interval time is prolonged.

Description

technical field [0001] The invention belongs to the technical field of agricultural protection, and in particular relates to a composition for preventing and controlling plant bacterial diseases and killing molluscs. Background technique [0002] The resistance of plant diseases to pesticides develops rapidly, and it is difficult to control them with pesticides. It has caused large-scale production reduction of agricultural products and caused serious economic losses. [0003] Copper preparations are mainly used to prevent and control bacterial diseases in agricultural production. These agents have severe drug resistance and low control efficiency, polluting soil, water and food in the environment, causing environmental and food safety risks. There are only a small number of other varieties that can be used for agricultural bacterial treatment, which are limited by resistance and control effect in actual production, and the promotion area is small. [0004] Bismerthiazol,...
