Problems solved by technology

[0003] At present, the pesticides used to prevent and control banana scab mainly include myclobutanil, pyraclostrobin, and thiophanate-methyl, etc. Long-term use of these pesticides can easily induce bacterial resistance, resulting in increased dosage and reduced control effect , shorter duration and other issues, which is not conducive to the sustainable development of the environment

Embodiment 1

[0047] A bactericidal composition containing tetraflumezazole and flusilazole is a suspending agent, including active ingredients and auxiliary agents. The active ingredients account for 2% to 50% of the total mass, and the active ingredients include: 1-25% tetraflumezazole, 1-25% flusilazole, 1-6% dispersant, 1-5% wetting agent, antifreeze 4-6%, thickener 0.1-2%, defoamer 0.1-1%, preservative 0.1-1%, structure regulator 0.5-2%, water to 100%

[0048]In this embodiment, the dispersant is polycarboxylate, glycerin fatty acid ester polyoxyethylene ether, alkylphenol polyoxyethylene ether formaldehyde condensate, lignosulfonate calcium salt, naphthalenesulfonate, diphenylphenol polyoxyethylene ether One or more of oxyethylene polyoxyformaldehyde condensates, more preferably the dispersant is polycarboxylate.

[0049] In this embodiment, the wetting agent is one of alkylphenol polyoxyethylene ether phosphate, polyoxyethylene polyoxypropylene ether block copolymer, and alkylphenol...

Embodiment 2

[0059] This embodiment is basically the same as Embodiment 1, the difference is that:

[0060] The active ingredients account for 14% of the total mass, and the mass ratio of tetrafluconazole to flusilazole is 4:10. In terms of weight percentage, it includes: tetrafluconazole 4%, flusilazole 10%, dispersant 4%, wetting agent 3%, antifreeze agent 4%, thickener 0.3%, defoamer 0.5%, preservative 0.5%, structure regulator 1%, water to make up to 100%.

Embodiment 3

[0062] This embodiment is basically the same as Embodiment 1, the difference is that:

[0063] The active ingredients account for 50% of the total mass, and the mass ratio of tetrafluconazole to flusilazole is 25:25. In terms of weight percentage, it includes 25% of tetrafluconazole, 25% of flusilazole, 5% of dispersant, 1% of wetting agent, 4% of antifreeze, 0.2% of thickener, 0.5% of defoamer, and 0.1% of preservative %, structure regulator 1.5%, and water to make up to 100%.

Abstract

The invention discloses a sterilization composition containing tetraconazole and flusilazole and application of the sterilization composition, and relates to the technical field of pesticides. The bactericidal composition comprises an effective component and an auxiliary agent, the effective component accounts for 2%-50% of the total mass, the effective component comprises tetraconazole and flusilazole, and the mass ratio of tetraconazole to flusilazole is (1-25): (1-25). According to the invention, tetraconazole and flusilazole with different action mechanisms are used as main components forcompounding, a broad-spectrum bactericidal composition for preventing and treating banana scab is selected out through screening, and the bactericidal composition has the characteristics of high efficiency, low toxicity, low residue and excellent prevention and treatment effect.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a bactericidal composition containing tetrafluconazole and flusilazole for preventing and treating banana scab and its application in preventing and treating banana scab. Background technique [0002] Banana scab is the main disease that affects the quality of bananas. It mainly damages leaves and green fruits. The fungus to treat the disease is scab. Infected leaves, many small dark brown to black spots appeared on the leaf surface in the early stage, densely piled up, like soot, appearing as stripes from the midrib to the edge of the leaf, and then the spots expanded, with a light yellow halo on the outer edge, and light yellow in the center Brown or gray, severely damaged leaves turn yellow, wither and die prematurely. Infected green fruits often produce many scattered or dense dark brown granules, short stripes and round or oval lesions on the curved part of the back of t...
