Bactericidal composition containing benzovindiflupyr

Abstract

The invention provides a synergetic bactericidal composition containing benzovindiflupyr. The composition is characterized by comprising an active component A and an active component B, wherein the A is benzovindiflupyr, and the B is one or more selected from furalaxyl-M, isofetamid, tolprocarb, picarbutrazox, zinc thiazole, dichlobentiazox, fluindapyr, and dipymetitrone; and besides, the a conventional pesticide preparation agent is prepared by mixing the active components and an auxiliary agent capable of use in pesticide preparation agent processing, and the composition is applied to plant disease prevention and control.

Description

technical field

[0001] The invention belongs to the technical field of pesticide application, and relates to a pesticide composition, specifically a fungicidal composition containing benzovinfluconazole, which is used for preventing and treating plant diseases. Background technique

[0002] In the process of agricultural production, plant diseases occur seriously, harming plant stems, leaves and other vegetative organs, as well as reproductive organs such as fruits, seeds, tubers, affecting plant photosynthesis, affecting the appearance of edible parts, causing a sharp drop in crop yield and serious quality decline . When the disease is severe, it leads to crop failure. Therefore, plant diseases have important control significance in production, and fungicides are the most economical, fast and effective method to prevent and control plant diseases.

[0003] The use of a single fungicide is likely to produce resistance or has a limited control spectrum, which cannot solve t...

Examples

Embodiment 1

[0023] Example 1: 12% EC

[0024] The formula is composed of: 4% of active ingredient A, 8% of active ingredient B, 5% of calcium dodecylbenzenesulfonate as an emulsifier, 4% of fatty alcohol polyoxyethylene ether as an emulsifier, and 100% of xylene as a solvent.

[0025] The preparation method is as follows: put all the materials into the batching kettle, stir and dissolve until completely transparent, and transfer to the storage tank for filling after passing the test.

Embodiment 2

[0026] Embodiment 2: 25% suspending agent

[0027] The formula is composed of: 10% active ingredient A, 15% active ingredient B, 5% wetting agent fatty alcohol polyoxyethylene ether, 4% dispersant alkylphenol polyoxyethylene ether phosphate, antifreeze agent ethylene glycol 5% %, thickener magnesium aluminum silicate 0.4%, water to make up to 100%.

[0028] The preparation method is as follows: put the active ingredient, wetting agent, dispersant, antifreeze and water into the stirring tank, after fully stirring, pump the material into the sand mill for full grinding, after the grinding is completed, pump into the high-speed shearing machine In the process, after adding the thickener, high-speed shearing is carried out, and the suspending agent is obtained after the shearing is completed.

Embodiment 3

[0029] Example 3: 45% water dispersible granules

[0030] The formula is composed of: 20% active ingredient A, 25% active ingredient B, 3% sodium lauryl sulfate wetting agent, 5% sodium lignosulfonate dispersant, 5% sodium sulfate disintegrating agent, binder Polyethylene glycol 0.5%, filler kaolin topped up to 100%.

[0031]The preparation method is as follows: after all the materials are mixed uniformly, they are pulverized by an airflow mill, and mixed uniformly again, then, a certain amount of water is added to knead the mixture, extruded and granulated, and dried and sieved to obtain water-dispersible granules.
