Abstract

The invention discloses a potato black scurf fungicide containing tolclofos-methyl. The potato black scurf fungicide is prepared from the following raw materials in parts by weight: 40 to 50 parts of tolclofos-methyl cream, 20 to 30 parts of benziothiazolinone, 30 to 40 parts of a thifluzamide and pyraclostrobin compound preparation, and 10 to 20 parts of a fluazinam and flutolanil compound preparation. The potato black scurf fungicide containing the tolclofos-methyl is suitable for agricultural application, high-efficiency, environmentally-friendly, and broad-spectrum, can reduce the pathogenic bacteria resistance generation speed and reduce the pesticide application cost, and has a remarkable synergism, a low resistance risk and a good effect of preventing and curing potato black scurf.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a fungicide for potato black mole containing tolclofos-methyl. Background technique [0002] Potatoes are perennial herbaceous plants belonging to the family Solanaceae, and the tubers are edible. In 2015, China launched the potato staple food strategy and listed it as another staple food besides rice, wheat, and corn. With the development of my country's potato industry, the benefits of planting have increased, the planting area has continued to expand, the period of crop rotation has been significantly shortened, and the occurrence of diseases has increased year by year. Therefore, the prevention and control of potato diseases has gradually attracted people's attention. [0003] Potato black spot disease (Rhizoctonia solani Kühn), also known as Rhizoctonia solani Kühn, is also called Rhizoctonia solani and stem base rot. At present, there are few pesticides registered for t...
