Embodiment 1

[0064] Example 1: 1% allylbenzothiazole syringstrobin granules

[0065]

[0066] Add xylene to allylbenthiazole and syringstrobin, then stir them fully to dissolve them completely; under stirring, slowly add propylene glycol to the system, stir fully for 30 minutes to dissolve them completely and form a stable solution .

[0067] First add 12-60 mesh zeolite into the mixer, then add the above stable solution into it, mix for 30 minutes, and get 1% allylbenthiazole syringstrobin granules after passing the screening and testing

[0068] The syringstrobin in this embodiment can be replaced by any one of kysstrobin, azoxystrobin, pyraclostrobin, trifloxystrobin, and alkoxystrobin to form a new embodiment.

[0069] This embodiment is applied to the prevention and treatment of rice blast. The 1% allylbenthiazole·syringstrobin granules were spread according to 200g a.i. / ha, and the control effects were 82.1% and 84.3% 7 days and 14 days after application. 8% allylbenthiazole gr...

Embodiment 2

[0070] Embodiment 2: 10% allylbenthiazole · azoxystrobin suspension concentrate

[0071]

[0072] The active ingredient, dispersant, thickener, wetting agent, antifreeze agent and water are uniformly mixed according to the ratio of the formula, and the 10% azoxystrobin suspension concentrate is obtained after high-speed shearing.

[0073] Azoxystrobin in this embodiment can be replaced by any one of kysstrobin, pyraclostrobin, syringstrobin, trifloxystrobin, and aceoxystrobin to form a new embodiment.

[0074] This embodiment is applied to the prevention and treatment of rice blast. 10% allylbenthiazole · azoxystrobin suspension was diluted with water at 200g a.i. / ha and sprayed, and the control effects were 92.7% and 88.9% 7 days and 14 days after the application. 8% allylbenthiazole granules were sprayed at 200ga.i. / ha, 25% azoxystrobin suspension was sprayed at 300g a.i. / ha, diluted with water and sprayed, and the control effects were 73.2% and 14 days after application...

Embodiment 3

[0075] Embodiment 3: 22% allylbenthiazole · syringstrobin suspending agent

[0076]

[0077]

[0078] The active ingredient, dispersant, thickener, wetting agent, antifreeze agent and water are uniformly mixed according to the ratio of the formula, and the 22% allylbenthiazole-syringstrobin suspension concentrate is obtained after high-speed shearing.

[0079] The syringstrobin in this embodiment can be replaced with any one of azoxystrobin, kysstrobin, pyraclostrobin, trifloxystrobin, and acelostrobin to form a new embodiment.

[0080] This embodiment is applied to the prevention and treatment of rice blast. 22% allylbenthiazole · syringstrobin suspension was diluted with water at 200g a.i. / ha and sprayed, and the control effects were 91.3% and 87.2% 7 days and 14 days after the application. 8% allylbenthiazole granules were sprayed according to 200ga.i. / ha, 20% syringstrobin suspension was sprayed according to 300g a.i. / ha, diluted with water, and the control effects ...

Abstract

The invention discloses a bactericidal composition containing probenazole, which is prepared by compounding active ingredients, namely, probenazole (A) and a strobilurin fungicide (B), wherein the strobilurin fungicide (B) is any one of azoxystrobin, kresoxim-methyl, pyraclostrobin, trifloxystrobin, coumoxystrobin or enestroburin; the weight ratio of the probenazole (A) to the strobilurin fungicide (B) is 100: 1-1: 10; the sum of weights of the probenazole (A) and the strobilurin fungicide (B) accounts for 1-80 percent by weight of the total weight of the bactericidal composition; and the bactericidal composition can be prepared into wettable powder, a suspension agent, granules or water dispersible granules or other conventional dosage forms. The bactericidal composition is used for controlling rice diseases, in particular to rice blast and the like. The bactericidal composition disclosed by the invention has the advantages of high efficiency, little environment pollution, capability of retarding generation of drug resistance among germs, and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a pesticide composition, in particular to a bactericidal composition containing allylbenthiazole. Background technique [0002] Rice blast has a large area of ​​occurrence, high prevalence, and serious damage. It is one of the important diseases of rice, and it is also an epidemic disease that spreads through air currents. It poses a great threat to rice production and seriously affects the yield and quality of rice. In recent years, due to the long-term single use of conventional pesticides such as rice blastin and tricyclazole, the resistance of rice blast fungus has become more and more serious, and the control effect has declined, which has become a major problem in chemical control. [0003] Allylbenzothiazole (Oryzaemate) is a salicylic acid immune system booster. Its structural formula is as follows: [0004] [0005] Allylbenzothiazole is a low-toxic fungicide, but i...
