Embodiment 1

[0021] Embodiment 1: 15% liquid

[0022] The formula is composed of: 5% of active ingredient A, 10% of active ingredient B, 6% of surfactant alkylphenol polyoxyethylene ether, and water to make up to 100%.

[0023] The preparation method is as follows: put all the materials into the preparation kettle, stir and dissolve until completely transparent, and transfer to the storage tank for filling after passing the test.

Embodiment 2

[0024] Embodiment 2: 26% suspending agent

[0025] The formula is composed of: 10% of active ingredient A, 16% of active ingredient B, wetting agent methacrylate maleate ethylene oxide and propylene oxide copolymer block 4%, dispersant lignosulfonate 3 %, antifreeze agent glycerin 5%, thickener xanthan gum 0.3%, water to make up to 100%.

[0026] The preparation method is: 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 it 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

[0027] Example 3: 50% Soluble Powder

[0028] The formula is composed of: active ingredient A is 15%, active ingredient B is 35%, wetting agent fatty alcohol polyoxyethylene ether 3%, dispersant p-methoxy fatty amidobenzenesulfonic acid 4%, filler bentonite is added to 100% %.

[0029] The preparation method is as follows: uniformly mix the active ingredients and various additives, put them into a mechanical pulverizer for primary pulverization, then pulverize through an airflow pulverizer, and then mix uniformly to obtain a soluble powder.

Abstract

The invention provides a potassium-phosphite-containing synergetic bactericidal composition, which is characterized by comprising active components of A and B, wherein A is potassium phosphate and B is Quinofumelin, and further comprising an auxiliary agent capable of being used for processing of a pesticide preparation. The bactericidal composition can be made into a common pesticide preparation and applied to prevent and control plant diseases.

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 potassium phosphite, which is used for preventing and treating plant diseases. Background technique [0002] In the process of agricultural production, plant diseases occur seriously, harming plant roots, stems, leaves and other parts, as well as reproductive organs such as fruits, seeds, tubers, affecting plant photosynthesis and plant growth, affecting the appearance of edible parts, and causing crop yields to drop sharply. The quality has dropped seriously. 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 spectru...
