Disease: root rot disease

Identification of antagonistic activity against Fusarium, and liquid fermentation of biocontrol Bacillus isolated from wolfberry (Lycium barbarum) rhizosphere soil

Researchers isolated a beneficial bacterium called Bacillus subtilis from wolfberry soil that fights a fungal disease called Fusarium root rot. Through careful optimization of growing conditions, they increased the bacteria’s effectiveness at killing the harmful fungus by about 15%. When added to wolfberry seedlings, this bacterium not only prevented fungal disease but also boosted plant growth significantly.

Co-application of dazomet and azoxystrobin reconstructs soil microbial communities and suppresses the violet root rot of Codonopsis tangshen under a continuous cropping system

Researchers found that treating soil with a combination of dazomet fumigant and azoxystrobin fungicide effectively eliminated violet root rot disease in Codonopsis tangshen plants grown repeatedly on the same land. The treatment worked by killing harmful disease-causing fungi while promoting beneficial soil bacteria that protect plant roots. This approach increased crop yield by 5-6 fold while maintaining important medicinal compounds in the plant roots, offering farmers a sustainable solution to a serious agricultural problem.
