therapeutic action: biocontrol of fungal pathogens

Bacillus subtilis Strain TCX1 Isolated from Ambrosia artemisiifolia: Enhancing Cucumber Growth and Biocontrol Against Cucumber Fusarium Wilt

Scientists discovered a beneficial bacterium called Bacillus subtilis strain TCX1 that can protect cucumber plants from a devastating fungal disease called Fusarium wilt. This bacterium both kills the fungus directly through special compounds it produces and strengthens the plant’s natural immune system. Additionally, the bacterium helps cucumber plants grow better by producing growth hormones and improving nutrient absorption, making it a promising natural solution for farmers.

Antagonistic mechanism of Bacillus velezensis HX0039 as a biocontrol agent against Trichoderma virens-induced ‘Sanghuang’ green mold

Scientists discovered a beneficial bacteria called Bacillus velezensis HX0039 that can protect ‘Sanghuang’ mushrooms from harmful green mold disease. This bacteria produces natural antifungal compounds like iturin A that stop the disease without harming the mushrooms or the environment. Testing showed it was 83% effective at preventing green mold and was completely safe for both mushroom cultivation and animal consumption, making it a promising alternative to chemical fungicides.

Biology and Application of Chaetomium globosum as a Biocontrol Agent: Current Status and Future Prospects

Chaetomium globosum is a common soil fungus that shows great potential for protecting crops from diseases and pests naturally. This review explains how it works—by producing toxic compounds against harmful fungi, directly attacking pathogens, and boosting plants’ own defense systems. When applied to seeds or soil, it has reduced crop diseases by up to 73% in field tests while also improving soil health and crop yields, making it a promising alternative to chemical fungicides.

Biocontrol of Seedborne Fungi on Small-Grained Cereals Using Bacillus halotolerans Strain B33

Researchers tested a naturally occurring soil bacterium called Bacillus halotolerans strain B33 to protect cereal seeds from harmful fungi. When seeds infected with fungal pathogens were treated with this bacterium, it successfully eliminated 83-100% of the fungi, depending on the pathogen and crop type. The treatment was as effective as commercial chemical disinfectants but offers a more environmentally friendly alternative for sustainable farming.
