Discussion

Experiment demonstrates significant fungal growth inhibition in potatoes, suggesting a novel biological control method.

The application of Bacillus licheniformis reduced R. solani fungal growth by 47.6%, effectively controlling the pathogen.
Seed germination was significantly affected, dropping to 6.7% in infected conditions compared to 97.7% control rates.
Use of immersion methods with bacteria resulted in a 30% reduction of root infection severity from R. solani.
This biological control method may offer a sustainable strategy for managing black scurf disease in potatoes.

Abdul-Karim et al. (2025) studied this question.
