Embodiment 180

[0117] Example 180% Tricyclazole·Bifentriazole Wettable Powder Control Effect of Rice Smut Disease

[0118] 50% tricyclazole, 30% bifentriazole alcohol, 4% polycarboxylate, 3% sodium lauryl sulfate, 2% saponin powder, diatomaceous earth added to 100%, the mixture is air-jet milled to prepare Obtain 80% tricyclazole · bibendontriazole wettable powder. The proportion is diluted and sprayed at 35 g / mu, sprayed at the early stage of the disease, sprayed once every 7 days, and sprayed twice in total. 7 days and 14 days after the last spraying, the disease index was investigated and the control effect was calculated. 7 days and 14 days after the application, the effects of preventing and treating rice false smut were 91.8%, 96.2%, respectively, and 20% tricyclazole wettable powder and 25% bifentriazole wettable powder followed the same method, respectively at 83 g / mu and 80 g / mu dilution, the control effects were 69.2% and 72.8% respectively 14 days after application.

Abstract

The invention discloses a bactericidal composition containing biphenyl triadimenol and a triazole type compound, and the bactericidal composition disclosed by the invention contains the synergistic effective dose of the biphenyl triadimenol and one of triazole type bactericides of flusilazole, myclobutanil, tricyclazole, penconazole, difenoconazole, triticonazole, epoxiconazole, ipconazole and tetraconazole, and the ratio of the two active ingredients in the bactericidal composition in parts by weight is (80:1)-(1:80). The bactericidal composition at least contains one surfactant, thereby being conductive to dispersion of the active ingredients in water during application. The bactericidal composition integrates protection, treatment and activity removal, can be used for various crops, such as wheat, rice, vegetables, fruit trees and the like, and is used for preventing and treating plant diseases caused by pathogens of ascomycotina, basidiomycotina and deuteromycotina.

Description

technical field [0001] The invention belongs to the field of agricultural fungicides, and relates to the preparation and application of a fungicidal composition containing biphenyltriazole alcohol and triazole compounds. Background technique [0002] Biphenyltriazole alcohol (bitertanol), is a triazole fungicide developed by Bayer, molecular formula: C 20 h 23 N 3 O 2 , chemical name: 1-(biphenyl-4-yloxy)-1-(1H-1,2,4-triazol-1-yl)3,3-dimethylbutan-2-ol. [0003] Structural formula: Bifentriazole is a mixture of two diastereoisomers, stable in neutral, acidic and alkaline media. Bifentriazole is a steroid demethylation inhibitor. Is a page fungicide with protective and therapeutic activity. By inhibiting the biosynthesis of ergosterol, thereby inhibiting spore germination, mycelium growth and sporulation. [0004] Long-term use of a single dose of bifentriazole can easily lead to drug resistance in diseases, leading to problems such as increased dosage, reduced contr...
