Embodiment 1

[0036] Biological Assay Example 1: Indoor Toxicity Test of Bixafen and Tefluconazole Compounded against Cucumber Powdery Mildew

[0037] Test object: Cucumber powdery mildew (Sphaerotheca fuliginea)

[0038] experiment method:

[0039] Measured by the pot cutting method. Select susceptible cucumber varieties for potting, and wait for the seedlings to grow to the 2-3 leaf stage for later use. The original drug of bixafen and the original drug of tetrafluconazole are respectively dissolved in dimethylformamide and acetone, and then diluted with 0.1% Tween-80 surfactant aqueous solution. 4 pots per treatment, 10 plants per pot, repeated 4 times, evenly spray 10ml of the medicinal solution on the cucumber seedlings until they are all wet, wait for the medicinal liquid to dry naturally for later use, and set only solvent and surfactant without effective The treatment of components was used as blank control. 24 hours after the chemical treatment, the fresh spores of powdery mild...

Embodiment 2

[0049] Biological Assay Example 2: Indoor Toxicity Determination Test of Bixafen and Tetrafluconazole Compounded to Wheat Leaf Rust

[0050] Test object: Puccinia recondita of wheat

[0051] experiment method:

[0052] Measured by the pot cutting method. Select the 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 bixafen and the original drug of tetrafluconazole are respectively dissolved in dimethylformamide and acetone, and then diluted with 0.1% Tween-80 surfactant aqueous solution. 4 pots per treatment, 10 plants per pot, repeated 4 times, evenly spray 10ml of the liquid medicine on the wheat seedlings until they are all wet, and wait for the liquid to dry naturally for later use, and set only solvent and surfactant without effective The treatment of components was used as blank control. 24 hours after the chemical treatment, the fresh spores of leaf rust fungus produced on the disease...

Embodiment 3

[0063] Example 3: 82% bixafen·tetrafluconazole aqueous emulsion (bixafen: tetrafluconazole=1:40)

[0064] Made according to the conventional process, including bixafen 2%, tetrafluconazole 80%, Solvesso 200 (solvent) 2%, 500# (emulsifier) ​​1.5%, 1601# (emulsifier) ​​2%, ethylene glycol Alcohol (antifreeze) 4%, 20% polydimethylsiloxane emulsion (defoamer) 0.4%, and deionized water make up to 100%.

Abstract

The invention discloses a bactericidal composition containing bixafen. The bactericidal composition comprises the following active components: bixafen and tetraconazole in a mass ratio of 1: 80 to 80: 1. The bactericidal composition can be used for prevention and treatment of rice blast, sheath blight, full rot, gray mold, leaf spot, powdery mildew and rust of crops, is especially applicable to prevention and treatment of powdery mildew and rust of vegetable, fruit trees and cereal crops and has the characteristics of low dosage, obvious synergism, good security, etc.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a bactericidal composition containing bixafen and its application in preventing and treating crop diseases, belonging to the technical field of pesticides. Background technique [0002] Powdery mildew and rust are widespread worldwide diseases caused by fungi of the family Erysiphaceae and rust fungus, respectively. [0003] In production, chemical pesticides are mainly used to control powdery mildew and rust. At present, it mainly relies on benzimidazoles, hydroxypyrimidines, phenoxyquinolines, triazoles and methoxyacrylate 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 phytotoxicity. Therefore, it is urgent to research and develop new effective control agents.
