Soil Health
Farmers and gardeners already use Trichoderma-based products to fight root rot and dampen-off disease, and this research points toward a next generation of those products that do more with far less chemical input.
Trichoderma are common soil fungi that gardeners and farmers already rely on to fight plant diseases. Scientists have discovered these fungi can also transform dissolved metals into tiny nanoparticles using their own metabolic chemistry. Those nanoparticles kill harmful bacteria and fungi while also helping plants grow stronger, potentially replacing some of the harsh synthetic pesticides we currently spray on crops.
Key Findings
Trichoderma species produce metabolites that reduce and stabilize metal ions into nanoparticles with antimicrobial and plant-growth-promoting properties.
Trichoderma-derived nanoparticles demonstrated both antibacterial and antifungal activity, suggesting dual-function biocontrol potential.
Field-level translation remains a key challenge, with physicochemical stability, dosage optimization, and regulatory pathways identified as primary barriers to practical deployment.

Fungi from the Trichoderma genus can act as tiny factories, using their natural chemistry to convert metal ions into nanoparticles that protect plants from disease and boost growth, offering a greener path than synthetic pesticides.

It could mean that people with celiac disease — roughly 1 in 100 worldwide — may one day safely eat bread made from real wheat, without sacrificing the taste...
Biocontrol is the use of living organisms—such as predatory insects, parasites, or microbial agents—to suppress pest populations and pathogens that threaten plant health. Rather than relying solely on synthetic pesticides, it harnesses natural ecological relationships to manage disease and
