Problems solved by technology

In particular, once the seeds are infected with bacteria, the risk of clubroot is greatly increased. Even if pesticides are sprayed in the later stage, it can only achieve "cure" but not "prevention", and rapeseed production will inevitably be affected.
[0005] In short, for the prevention and control of clubroot in rapeseed, there has not been found a method that has no impact on soil, humans and animals, and can effectively control rapeseed clubroot from the source

Abstract

The invention provides a seed coating agent capable of efficiently preventing the rape clubroot disease. The seed coating agent comprises, by weight, 1-5 parts of active components, 1-10 parts of film forming agents, 1-10 parts of dispersing agents and 90-100 parts of auxiliaries. The active components include at least one of 6% oligosaccharide link protein, Pulvtong, 3% plant activator protein. After being mixed, the active components, the film forming agents, the dispersing agents and the auxiliaries are smashed till the granularity is not larger than 5 microns, and the seed coating agent is obtained. The seed coating agent has no toxin or harm to soil, people and livestock and has an excellent prevention effect on the rape clubroot disease, the prevention effect can be over 90%, implementation is convenient, and the seed coating agent has good market application prospects.

Description

technical field [0001] The invention belongs to the field of clubroot prevention and treatment, and in particular relates to a seed coating agent for effectively preventing and treating rape clubroot. Background technique [0002] Clubroot is a soil-borne disease caused by Plasmodium brassicae. When the environmental conditions are favorable for the disease to occur, clubroot can lead to a serious decline in the yield of rapeseed crops or even failure, which seriously threatens the production of rapeseed. [0003] At present, for the control of clubroot, chemical control, crop rotation and soil improvement are mainly adopted. Although soil improvement (such as applying a large amount of lime) can play a good role in preventing and controlling clubroot, it is easy to cause soil compaction and reduce soil fertility. Clubroot crop rotation is difficult because the growth of cruciferous weeds in dryland croplands cannot be eliminated. Chemical control methods mostly use chemi...
