Agronomists find microbes to protect tomatoes from dangerous fungus


by Russian Foundation for Basic Research
RUDN University agronomists and colleagues from Tunisia have discovered a way to stop the spread of a phytopathogenic fungus Botrytis cinerea. It affects crops, especially tomatoes. The Trichoderma fungus and the Pseudomonas bacterium can protect the crop from this pathogen. The results have been published in the journal Agronomy.

Botrytis cinerea is a gray mold that affects many plants. It is dangerous for strawberries, grapes, onions, and tomatoes. Fungicides are the usual way to combat phytopathogens. However, antifungal substances are dangerous to humans and the environment. In addition, the fungus becomes resistant to these drugs over time. The preferred alternative is biological control methods. RUDN University agronomists and colleagues from Tunisia proposed using other microbes to fight the pathogen: the Trichoderma fungus and bacteria from the Pseudomonas genus.
