Problems solved by technology

However, there are some differences in the disease prevention spectrum between the two. At the same time, diniconazole belongs to the triazole fungicides and has a strong inhibitory effect on plants. The operation technology is strict. If you do not pay attention to increasing the dosage or uneven seed dressing, phytotoxicity will occur.

Abstract

The invention discloses a sterilization compound. The invention essentially relates to a powder agent or a liquid agent mixed by active sterilization ingredients of diniconazole and fludioxonil. The weight percentage of the diniconazole and fludioxonil contained in the preparation is 1 : 1 to 1 : 20. The invention has the advantages of convenient operation, remarkably reducing using difficulty and no remarkable inhibitory phenomena by adopting wet mixing or dry mixing. The invention can remarkably improve the germinating capacity and rate of emergence of seeds; the control effects on the soil-borne diseases of wheat like foul foot, banded sclerotial blight, full rot, etc., are improved by 8 to 12 percent compared with the control effects of a single agent. The seedling strengthening effect is remarkable and after the seeds are treated, the green weight for a single plant of the weight is remarkably improved; after being seeded for 30 days, the average green weight for single plant is increased by about 15 percent according to investigation. The invention improves the stress tolerance capacity of the wheat, has remarkable vigorous growing control effect before the end of the year and improves the lodging resistance capacity in the watery stage. The invention can ease the frozen injures caused by coldness in the late spring in the north areas.

Description

Technical field [0001] The invention relates to a formula of a fungicide for preventing disease and increasing production of crops, in particular to a fungicidal composition. Background technique [0002] At present, soil-borne diseases such as sheath blight, total erosion, and root rot have seriously affected the yield and quality of wheat and other crops. Diniconazole and fludioxonil are chemicals commonly used in the prevention and treatment of this type of disease in production. However, there are certain differences in the disease prevention spectrum between the two. At the same time, diniconazole is a triazole fungicide which has a strong inhibitory effect on plants. The operation technology requirements are strict. If you do not pay attention to increasing the dosage or the uneven seed dressing, it will cause phytotoxicity. . Summary of the invention [0003] The purpose of the present invention is to provide a bactericidal composition that can expand the disease preventi...
