Embodiment 1

[0039] Example 1: Process the solid original drug pyraclostrobin and difenoconazole to more than 800-1000 mesh by means of jet crushing, then accurately weigh 20% pyraclostrobin and difenoconazole 10%, propiconazole 8%, dispersant alkylnaphthalene formaldehyde condensate sulfonate 6%, wetting agent alkylnaphthalene sulfonate 4%, binder alkyl aryl polyoxyethyl ether 5%, After the filler kaolin is supplemented, it is fully mixed and evenly mixed. Finally, after passing the quality inspection of various technical indicators, it can be packaged as a 38% pyraclostrobin · difenoconazole · propiconazole wettable powder.

Embodiment 2

[0040] Example 2: Process the solid original drug pyraclostrobin and difenoconazole to more than 800-1000 mesh by means of jet crushing, then accurately weigh 20% pyraclostrobin and difenoconazole 10%, propiconazole 8%, dispersant alkylnaphthalene formaldehyde condensate sulfonate 6%, wetting agent alkylnaphthalene sulfonate 4%, binder alkyl aryl polyoxyethyl ether 5%, Add deionized water to 100% for initial mixing, shearing, stirring, and dispersing. After being prepared into a slurry, it is ground for 1-2 hours by a horizontal sand mill, so that the particle size is below 5 microns, and it has a certain viscosity. Fluid 38% pyraclostrobin · difenoconazole · propiconazole liquid suspension preparation.

Embodiment 4

[0041] Example 4: Process the solid original drug pyraclostrobin and difenoconazole to more than 800-1000 mesh by means of jet crushing, then accurately weigh 20% pyraclostrobin and difenoconazole 10%, propiconazole 8%, dispersant alkylnaphthalene formaldehyde condensate sulfonate 6%, wetting agent alkylnaphthalene sulfonate 4%, adhesive alkylaryl polyoxyethyl ether 5% filler Kaolin and an appropriate amount of water are fully mixed and stirred to form a plastic material, which is extruded and granulated, dried, and sieved. Finally, after passing the quality inspection and various technical indicators, it can be packaged into 38% pyraclostrobin difenoconazole ·Propiconazole water-dispersible granules.

Abstract

The invention relates to a sterilizing compound preparation and application thereof. The compound preparation is prepared by compounding pyraclostrobin, difenoconazole and propiconazole. The composition comprises 1-30% of pyraclostrobin, 1-30% of difenoconazole, 1-35% of propiconazole, 1-5% of dispersing agents, 1-5% of wetting agents, 1-5% of bonding agents and the balance of fillers (or distilled water). The composition can prevent such diseases harming rice through seed and soil infection and transmission as bakanae disease and does not leave any harmful residue affecting seed germination, seedling development, plant growth and products.

Description

technical field [0001] The invention relates to a pesticide mixing technology, in particular to a bactericidal compound preparation composed of pyraclostrobin, difenoconazole and propiconazole and its application. technical background [0002] pyraclostrobin [0003] The mechanism of action of pyraclostrobin is as an inhibitor of mitochondrial respiration. Mitochondria cannot produce and provide the energy required for normal cell metabolism, eventually leading to cell death. It can control most diseases such as Ascomycetes, Basidiomycetes, Deuteromycetes and Oomycetes. It has a strong inhibitory effect on spore germination and the growth of mycelium in leaves, and has protective and therapeutic activities. Possesses permeability and local systemic activity, long-lasting effect, resistant to rain erosion. [0004] Difenoconazole [0005] The trade names of difenoconazole (English common name difenoconazole) are difenoconazole, difenoconazole, and Shigao. Preparation pr...
