Embodiment 180

[0104] Example 180% Triadimefon·Bifentriazole WP WP Control Efficacy Test of Wheat Rust

[0105] Triadimefon 65%, bifentriazole alcohol 15%, polycarboxylate 4%, sodium lauryl sulfate 3%, saponin powder 2%, diatomaceous earth are added to 100%, the mixture is carried out jet milling, and the preparation 80% triadimefon·bifentriazole wettable powder was obtained. 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 wheat rust were 90.8%, 96.3%, respectively, and 25% triadimefon wettable powder and 25% bifentriazole wettable powder followed the same method at 75 g / mu and 80 g / mu respectively. Gram / mu dilution is used, and the control effects are 69.2% and 78.8% respectively 14 days after ap...

Embodiment 240

[0107] Example 240% Cycloconazole·Bifentriazole Emulsion in Water Emulsion Control of Banana Leaf Spot Drug Efficacy Test

[0108] Cycloconazole 10%, Bifentriazole 30%, Methanol 8%, Alkylphenol Polyoxyethylene Ether Phosphate 5%, Polyvinyl Alcohol 3%, Alkylbenzene Sulfonate Calcium 5%, Sodium Chloride 2% , deionized water to 100%, and mixed to prepare 40% cyproconazole·bifentriazole aqueous emulsion. The ratio is 2000 times diluted and sprayed, sprayed at the early stage of the disease, sprayed once every 7 days, and sprayed 3 times in total, and investigated the disease index and calculated the control effect 7 days and 14 days after the last spraying. 7 days and 14 days after the application, the effects of preventing and treating banana leaf spot were 91.5%, 95.9%, respectively. The 40% cycloconazole wettable powder and the 25% bifentriazole wettable powder followed the same method, respectively, by 1500 times and 800 times. When used in two-fold dilution, the preventive e...

Embodiment 348

[0110] Example 348% Hexaconazole·Bifentriazole Suspoemulsion Efficacy Test for Controlling Rice Sheath Blight

[0111] Hexaconazole 8%, bifentriazole 40%, polycarboxylate 3%, lignosulfonate 3%, sodium dodecylbenzenesulfonate 4%, nonylphenol polyoxyethylene ether modified phosphoric acid Add 5% ester, 6% acetone, 1% xanthan gum, 4% ethylene glycol, and deionized water to 100%, and mix to prepare 48% hexaconazole·bifentriazole suspoemulsion. The ratio was diluted and sprayed at 45 g / mu, sprayed at the early stage of the disease, once every 7 days, and sprayed twice in total, and the disease index was investigated 7 days and 14 days after the last spraying and the control effect was calculated. 7 days and 14 days after the application, the effects of controlling rice sheath blight were 91.3%, 95.8%, respectively, and 10% hexaconazole suspension concentrate and 25% bifentriazole wettable powder followed the same method, respectively at 56 g / mu and 80 g / mu dilution, the control ef...

Abstract

The invention discloses a pesticide composition containing bitertanol. The pesticide composition contains the bitertanol of synergistic effective dose and one of triadimefon, tebuconazole, hexaconazole, cyproconazole, triadimenol, flutriafol and diniconazole serving as triazole bactericides, wherein the weight part ratio of the two active ingredients in the pesticide composition is 80:1-1:80. The pesticide composition at least contains one surfactant which is favorable for dispersion of the active ingredients in the water during application. The pesticide composition has protection, treatment and eradication activities, can be used for multiple crops such as wheat, rice, vegetables, fruit trees and the like, and can be used for preventing and controlling plant diseases caused by pathogenic bacteria of taphrinomycotina, basidiomycolina and deuteromycotina.

Description

technical field [0001] The invention belongs to the field of agricultural fungicides and relates to the preparation and application of a pesticide composition containing bifentriazole. 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 control effect, and shortened duration, w...
