Embodiment 1

[0031] Biological Assay Example 1: Indoor Toxicity Determination Test of Benzene Fluconazole and Chloroprexate Compound to Cucumber Powdery Mildew Bacteria

[0032] Test object: Cucumber powdery mildew (Sphaerotheca fuliginea (Sch.) Poll) (collected from wild cucumber powdery mildew strains in the field, and separated and purified)

[0033] Test method: The test refers to the Agricultural Industry Standard of the People's Republic of China NY / T 1156.11-2008 "Indoor Bioassay Test Guidelines for Pesticides and Fungicides Part 11: Potted Plant Method for Controlling Melon Powdery Mildew Test", and the potted plant method was used for determination.

[0034] Sow susceptible cucumber varieties, and grow them in pots until the stage of 2-4 true leaves is set aside. The original drug of benzovinfluconazole and the original drug of chlorpyrexate were respectively dissolved in dimethylformamide and acetone, and then diluted with 0.1% Tween-80 surfactant aqueous solution. For each trea...

Embodiment 2

[0043] Biological Assay Example 2: Indoor Toxicity Determination Test of Benzene Fluconazole and Cloclostrobin Compound on Wheat Powdery Mildew Bacteria

[0044] Test object: wheat powdery mildew (Erysiphe graminis) (collected from wild wheat powdery mildew strains in the field, and separated and purified)

[0045] Test method: The test refers to the Agricultural Industry Standard of the People's Republic of China NY / T 1156.4-2006 "Indoor Bioassay Test Guidelines for Pesticides and Fungicides Part 4: Potted Plant Method for Controlling Wheat Powdery Mildew Test", and the potted plant method was used for determination.

[0046] Select susceptible wheat varieties for potting, and wait for the seedlings to grow to the 2-3 leaf stage for later use. The original drug of benzovinfluconazole and the original drug of chlorpyrexate were respectively dissolved in dimethylformamide and acetone, and then diluted with 0.1% Tween-80 surfactant aqueous solution. 3 pots per treatment, 10 pla...

Embodiment 1、20

[0055] Formulation example 1, 20% benzovinfluconazole · chlorpyracillin emulsifiable concentrate

[0056] 10% Benzofenfluconazole, 10% Chloroprexate, 5% Phenylphenol Polyoxyethylene Ether (Emulsifier), 2% Alkylphenol Formaldehyde Resin Polyoxyethylene Ether (Emulsifier), Dodecane Calcium phenyl sulfonate (emulsifier) ​​5%, isopropanol (co-solvent) 4.5%, xylene (solvent) supplemented to 100%.

Abstract

The invention discloses a bactericidal composition containing benzovindiflupyr. The effective constituents of the bactericidal composition are benzovindiflupyr and triclopyricarbe at a mass ratio of 1: 50 to 50: 1. The composition has an obvious synergistic effect and high safety, is suitable for preventing and curing powdery mildew and gray mold of crops, and is particularly suitable for preventing and curing powdery mildew and gray mold of vegetables, fruit trees and cereal crops.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing benzovinfluconazole and its application for preventing and treating crop diseases, and belongs to the technical field of pesticides. Background technique [0002] Powdery mildew is a widespread worldwide disease caused by the powdery mildew family of fungi; Botrytis cinerea is a fungal disease that is common and difficult to control in open field and protected crops. It is caused by Botrytis cinerea infection Sincerely. [0003] In production, chemical pesticides are mainly used to control powdery mildew and gray mold. At present, it mainly relies on benzimidazoles, triazoles, methoxyacrylates and dicarboximide fungicides. These agents have produced varying degrees of resistance due to long-term use, and the control effect has decreased. In addition, triazole agents can inhibit the growth of crops when used in large doses, and easily cause phyt...
