Abstract

The invention relates to the technical field of pesticides, in particular to a seed potato coating agent. The seed potato coating agent comprises an active component and a film-forming agent. The active component comprises, by weight, 4 to 8 parts of imidacloprid, 3 to 6 parts of thiabendazole, 2 to 4 parts of uniconazole, 2 to 5 parts of plant growth inhibitor, 8 to 12 parts of dispersant, 0.2 to 0.8 part of trace element fertilizer solution, and 0.2 to 0.6 part of anti-freezing agent. The seed potato coating agent is effective in controlling dry rot and basal stem rot in the potato and is low in cost; the seed potato coating agent is effective in supplementing trace elements such as molybdenum and boron, adjusting growth and development of the potato, improving availability of soil fertilizers and increasing the yield. The seed potato coating agent reaches the standards of like domestic products in terms of stability, film-forming ability and coating strength. By the use of the seed potato coating agent, occurrence rates of the dry rot and basal stem rot in the potato are minimized to 2.8% and 3.2%, respectively.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a potato seed coating agent. Background technique [0002] Potato is an important food and vegetable crop in my country. It has strong adaptability, high yield, and rich nutrition. It is known as "underground apple", "second bread", and "golden eggs" for farmers to get rich. It is the world's food market. It is not only a major food, but also an important industrial raw material, which has great development value. [0003] Potato stem rot (Rhizoctonia solani Kühn), as a new disease in the potato industry, is a disease caused by Rhizoctonia solani. All of them can be affected, and their symptoms are complex and diverse. The degree of susceptibility of potato varieties is different, and the period of onset is different, and the symptoms and characteristics of the symptoms are also different. It is often that when symptoms occur in underground rhizomes, they cannot be found in t...
