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 bactericidal composition. The invention is mainly a powder or a liquid prepared by mixing diniconazole and fludioxonil fungicidal active ingredients; the weight part of diniconazole and fludioxonil contained in the preparation The ratio is 1:1-1:20. The invention has the following advantages: easy to operate, significantly reduced difficulty in use, and no obvious inhibition phenomenon when wet mixing or dry mixing is used. Can significantly improve the germination rate and emergence rate of seeds. Compared with single agent, the control effect on wheat soil-borne diseases such as root rot, sheath blight, and take-all is increased by 8-12%. The seedling strengthening effect is obvious, and the fresh weight of wheat per plant is significantly increased after seed treatment. The survey after 30 days of sowing shows that the average fresh weight of single plant increases by about 15%. Improve the stress resistance ability of wheat, the effect of controlling prosperity before the year is obvious, and improve the lodging resistance ability at the filling stage. In the northern region, it can alleviate the freezing damage caused by the late spring cold.

Description

technical field [0001] The invention relates to a formulation of a fungicide for disease prevention and production increase of crops, in particular to a fungicide composition. Background technique [0002] At present, soil-borne diseases such as sheath blight, take-all, and root rot seriously affect the yield and quality of crops such as wheat. Diniconazole and fludioxonil are chemical agents commonly used in production to control this type of disease. 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. . Contents of the invention [0003] The object of the present invention is to provide a bactericidal composition that can expand the disease prevention spectrum of the medicament, allevia...
