Disease: Seedling damping-off

Rhizoctonia solani causes okra (Abelmoschus esculentus) seedling damping-off in South China with biological characterization and fungicide sensitivity profiling

Researchers identified Rhizoctonia solani as the fungus causing a serious disease in okra seedlings in southern China that was destroying about 35% of crops. The fungus dies when exposed to high temperatures (45-48°C) and grows best at about 28°C. Among seven tested antifungal treatments, a combination of trifloxystrobin and tebuconazole was most effective at controlling the pathogen, providing farmers with practical strategies for managing this crop disease.

Mycoviruses: Antagonistic Potential, Fungal Pathogenesis, and Their Interaction with Rhizoctonia solani

This comprehensive review explores how viruses that infect fungi, called mycoviruses, could help farmers control rice diseases. Rice sheath blight caused by the fungus Rhizoctonia solani causes significant crop losses worldwide. Scientists have discovered that certain mycoviruses can weaken this pathogenic fungus, making them promising biological alternatives to chemical fungicides that can harm the environment and encourage disease resistance.
