Seed treatment agent

Abstract

The invention discloses a seed treatment agent used for preventing fungus. The seed treatment agent is characterized in containing natamycin. The seed treatment agent is prepared from natamycin, an adhesive, an anti-oxidant, a chelating agent, or water; or natamycin, other antifungal ingredients, the adhesive, the anti-oxidant, the chelating agent, and water. Seed mildew and fungal diseases can be prevented effectively via treating of seeds with the seed treatment agent, bud ratio and bud growing conditions can be improved further, and crop yield is increased. The seed treatment agent is high in efficiency, wide in pH application range, high in specificity and security, and long in antibacterial action time.

Description

technical field [0001] The invention belongs to the fields of biotechnology and agriculture, and provides a seed treatment agent containing natamycin for preventing the mildew of seeds and the invasion of fungal diseases. Background technique [0002] For agricultural production, the quality of seeds directly affects the production of crops. Some pathogenic fungi that may be carried by the seeds can affect the germination rate and bud potential of the seeds, and even cause discoloration and rot of the seeds and diseases at the seedling stage. For example, Aspergillus niger often carried by peanut seeds can cause stem rot and crown rot, Dispora cocoa can cause stem rot and dry rot, and Cercospora arachis can cause brown spot on the tail shell. The coccidiospora that may be carried by corn seeds can cause grain rot and stem rot, and Cephalosporium maize can cause slow wilt. Some pathogenic fungi may exist in the seeds of various plants. For example, Helmintheroides umbilicus...

Problems solved by technology

However, because natamycin is insoluble in water, it is difficult to form a uniform and stable suspension in water, it is easily oxidized, and it is sensitive to ultraviolet rays, etc., so its application in crop production is relatively limited.
