Embodiment 1

[0033] Embodiment 1 (the preparation method of 60% metconazole · flufenapyramide wettable powder)

[0034] Raw material formula: by mass percentage

[0035]

[0036] The preparation method is as follows:

[0037] According to the formula, weigh each component in proportion, put it into a ball mill and mill it for 30 minutes, filter, pump it into the dispersion tank for 3 minutes at high speed and then grind it fully with a sand mill to control the particle diameter of the solid component within 2 microns, and the grinding is completed Finally, stir evenly to obtain the suspension concentrate product.

Embodiment 2

[0038] Embodiment 2 (the preparation method of 30% metconazole · flufenapyramide suspension concentrate)

[0039]

[0040] Preparation method: same as Example 1.

Abstract

The invention discloses a bactericide composition containing metconazole and fluxapyroxad. The active components of the bactericide composition are metconazole and fluxapyroxad, wherein the mass ratio of metconazole to fluxapyroxad is 1:20 to 20:1, and the mass percentage of the active components in the composition is 5-60%. The bactericide composition has high bactericidal activity, delays the generation and development of drug resistance of pathogens, reduces the preventing and treating dosage in actual production, is economical, efficient, safe and environment-friendly, and has obvious preventing and treating effects on rice sheath blight disease.

Description

technical field [0001] The invention relates to the field of agricultural fungicides, in particular to a fungicidal composition containing metconazole and flufenapyramide, which is used for preventing and treating rice sheath blight. Background technique [0002] Rice sheath blight is a worldwide epidemic disease caused by Rhizoctonia solani, and it is also one of the most important diseases of rice in my country. Its distribution is very wide, and it occurs in all major rice producing areas in my country, especially in the middle and lower reaches of the Yangtze River and South China. The damage is very serious, resulting in a sharp decline in yield. Breeding and promoting disease-resistant varieties is one of the important measures to prevent and control rice sheath blight. In recent years, although scholars at home and abroad have made a lot of progress in disease-resistant breeding, there is still no one that is completely resistant to rice sheath blight. Immunized rice...
