Problems solved by technology

[0004] At present, the pesticide preparations with thiram as the active ingredient are mainly 50%, 70%, and 80% wettable powder. In the actual use process, there is serious dust pollution, which is very harmful to the environment and human health, and the utilization rate is low. , short duration and other shortcomings, the inventors found that mixing thiram and tebuconazole active ingredients can improve its utilization rate, compared with the use of thiram and tebuconazole single agent, it can reduce the amount of medicament application, which is friendly to the environment , saving costs and slowing down the development of pest resistance

Embodiment 1

[0022] Weigh 9% of the original powder of tebuconazole, 73% of the original powder of thiram, 4% of the dispersant sodium naphthalenesulfonic acid formaldehyde condensate, 2% of the wetting agent sodium lauryl bisulfate, 2% of the pulling powder, and disintegrate 4% decomposed modified starch, 2% carrier kaolin; it is mixed according to the general method, and after stirring evenly, it is pulverized by an airflow mill to obtain mother powder, and the mother powder is mixed with 4% binder sodium polyacrylate 80, and then Granulate, dry, and sieve to obtain about 96% of 80% tebuconazole and thiram water dispersible granules. The content of active ingredients after inspection is tebuconazole 8.2% thiram 72.4%, moisture ≤ 2.5%, pH value 7.4 sieve (through 75um sieve) ≥ 8%, suspension rate ≥ 65%, persistent foaming (1min) ≤ 10mL , wettability ≤ 1min, dust ≤ 3.0%, accelerated heat storage stability qualified.

Embodiment 2

[0024] Weigh 12% of the original powder of tebuconazole, 70% of the original powder of thiram, 3% of the dispersant lignosulfonate, 3% of the wetting agent sodium butylnaphthalene sulfonate, 1% of sodium dodecyl hydrogen sulfate, and disintegrate Glucose 4% of solution agent, 3% of carrier white carbon black; It is mixed by general method, after stirring evenly, pulverizes to obtain mother powder through jet mill, mother powder is mixed with 4% binder sodium polyacrylate 80, Then granulate, dry, and sieve to obtain about 96% of 80% tebuconazole and thiram water dispersible granules. After testing, the active ingredient content is difenoconazole 11% thiram 69%, moisture ≤ 2.5%, pH value 7.2 sieve (through 75um sieve) ≥ 98%, suspension rate ≥ 65%, long-lasting foaming (1min) ≤10mL, wettability ≤1min, dust ≤3.0%, qualified for accelerated thermal storage stability.

Embodiment 3

[0026] Weigh 16% of the original powder of tebuconazole, 66% of the original powder of thiram, 3% of the dispersant sodium naphthalenesulfonate formaldehyde condensate, 1% of the wetting agent sodium lauryl hydrogensulfate, 2.5% of the pulling powder, and disintegrate Debonding agent ammonium sulfate 5.5%; It is mixed according to the general method, after stirring evenly, pulverizes through jet mill to obtain mother powder, mother powder is mixed with 6% binder carboxymethyl cellulose, then granulated, Dried and sieved to obtain about 96% of 80% difenoconazole and thiram water dispersible granules. The content of active ingredients tested is tebuconazole 15% thiram 65%, moisture ≤ 2.5%, pH value 7.6 sieve (through 75um sieve) ≥ 98%, suspension rate ≥ 65%, persistent foaming (1min) ≤ 10mL , wettability ≤ 1min, dust ≤ 3.0%, accelerated heat storage stability qualified.

Abstract

The invention relates to a sterilizer composition consisting of tebuconazole and thiram which serve as effectively active components. The ebuconazole-thiram sterilizer composition contains 5-20% by weight of tebuconazole and 51-73% by weight of thiram. The composition is preferably in the form of water dispersible granule, suspending agent, oil suspending agent, emulsion in water, wettable powderand missible oil. The ebuconazole-thiram sterilizer composition can be applied for preventing and removing gibberellic disease, sphaerotheca fuliginea, banded sclerotial blight, rice blast, blight andverticillium wilt, alternaria leaf spot, cladosporium cucumerinum and anthracnose which happen to wheat, rice, cotton, apple treess and grape plants.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition composed of effective active ingredients tebuconazole and thiram, and belongs to the technical field of compound pesticides. Background technique [0002] Tebuconazole belongs to triazole fungicides, is a sterol deradicalization inhibitor, and is an efficient protective fungicide used for seed treatment or surface spraying of important economic crops. [0003] Thiram, English common name thiram, is a protective fungicide, which has a good control effect on downy mildew, blight, anthracnose, cereal smut, and seedling yellow blight of various crops. [0004] At present, the pesticide preparations with thiram as the active ingredient are mainly 50%, 70%, and 80% wettable powder. In the actual use process, there is serious dust pollution, which is very harmful to the environment and human health, and the utilization rate is low. , short duration and other shor...
