Embodiment 2

[0021] Preparation method example 2: 48% thiazole zinc · thiamethoxam ketone water dispersible granule.

[0022]

[0023]

[0024] The above formula is dry crushed, granulated, dried and sieved according to the proportion to prepare the 48% thiazole zinc·thiamethonium water dispersible granule.

Embodiment 3

[0025] Preparation method example 3: 24% thiazole zinc · thiamethondone suspension concentrate.

[0026]

[0027] The above-mentioned materials are pre-crushed in proportion, then added to a sand mill for grinding, and prepared after high-shear mixing to prepare a 24% thiazolium-thiazolium suspending agent.

[0028] Biological Assay Example 1: Combined virulence assay of thiazole zinc and thiamethoxam on downy mildew of cucumber.

[0029] The test agent used 95% thiazole zinc original drug and 95% thiamethoxam original drug.

[0030] Referring to the standard bioassay method NY / T1156.2-2006, the drug-containing medium method is adopted: take 6 mL of the drug solution with a series concentration of each single agent and mixed agent, add it to 54 mL of PDA medium cooled to 45 ° C, and prepare the A plate of drug-containing media is required at the final concentration. Then, a 6 mm-diameter mycelial block was prepared from the edge of the Cucumber downy mildew colony culture...

Embodiment 2

[0035] Biological Assay Example 2: Field Test of Controlling Cucumber Bacterial Leaf Spot.

[0036] The test site is located in Laokeng Village, Renshan Town, Huidong County, Huizhou City, Guangdong Province. The test time is May 2013, and the spray method is used. Using 20% ​​thiazole zinc suspension concentrate and 3% thiamethoxam wettable powder as contrast agents, the test established 5 drug treatments altogether, each treatment was repeated 4 times, and the number of cucumber diseased plants was investigated before application. Investigate the control effect once every 7 days, record the number of diseased plants, and calculate the control effect. The test results are shown in Table 2.

[0037] Table 2. Experimental results of controlling cucumber bacterial angular spot.

[0038]

[0039] As can be seen from Table 2, the effects of 33% thiazole zinc thiamethoxalone wettable powder, 48% thiazole zinc thiamethoxam water dispersible granules, and 24% thiazole zinc thiame...

Abstract

The invention discloses an antibacterial composition containing zinc thiazole and benziothiazolinone. The antibacterial composition comprises effective components of zinc thiazole and benziothiazolinone. The mass ratio of zinc thiazole to benziothiazolinone is (1-15):(15-1). The weight sum of zinc thiazole and benziothiazolinone accounts for 5-91% of the weight of the composition in percentage. According to practical application demands, the dosage form of the antibacterial composition provided by the invention refers to one of missible oil, micro-emulsion, suspending agents, wettable powder and water dispersible granules. The antibacterial composition can be used for preventing and treating fungous and bacterial diseases.

Description

technical field [0001] The fungicidal composition involved in the present invention uses thiazole zinc and thiamethoxam as active ingredients, and is used for preventing and treating crop diseases such as cucumber downy mildew and cucumber bacterial angular spot. Background technique [0002] The problem of resistance to agricultural fungal and bacterial diseases is a global problem, and it has always been a key topic of concern to agricultural science and technology workers. With the continuation of chemical disease control year after year, the increase in the use of pesticides and the unscientific use of pesticides, the resistance of bacteria is becoming more and more serious, and the types of resistant bacteria are increasing. At the same time, the high-intensity use of pesticides leads to excessive pesticide residues in agricultural products, environmental pollution and increased costs of pesticides for farmers, which is not conducive to the sustainable development of ag...
