A research team has identified the fungus Chaetomium globosum as a natural suppressor of Septoria tritici blotch in wheat. The findings, published in Scientific Reports, show that the fungus significantly reduces infection levels in susceptible wheat varieties.
Why it matters
As the pathogen Zymoseptoria tritici grows resistant to conventional chemical fungicides, this biological approach offers a new path for protecting wheat crops. The research highlights the potential for using natural endophytes to bolster plant immunity.
Liquid applications of Chaetomium globosum inhibited spore germination by 80% in laboratory tests. The fungus was selected after researchers screened 45 different fungal endophytes for their potential to suppress the disease.
The players
Scientific Reports
An open-access, peer-reviewed journal publishing research across all areas of the natural sciences and medicine.
The details
The fungus acts by alerting the plant’s immune system while secreting antifungal compounds. It also produces ammonia and auxin, a plant hormone that regulates growth and stress responses. Researchers successfully demonstrated these protective effects by growing the fungus in liquid and spraying it directly onto infected wheat plants.

The Tech Race
This development follows a pattern set by the ongoing research into biological control agents for crop protection. It marks a shift toward using plant-associated fungi to address the problem of chemical fungicide resistance in cereal production.
This research is currently in the experimental stage and is not yet available for commercial use. If successful in upcoming field trials, the treatment could eventually provide farmers with a new tool to manage crop disease as chemical options become less effective.
The takeaway
The study suggests that naturally occurring endophytes could eventually replace or complement synthetic chemicals for crop protection. Watch for upcoming field trial results to determine if this biological control can perform outside of controlled laboratory environments.
What happens next
Future research will focus on pinpointing the specific antifungal compounds produced by the fungus and conducting field trials to evaluate the feasibility of coating wheat seeds with the agent.
