CLASSIFICATION
Fungi, Agaricomycetes, Ceratobasidiaceae, Rhizoctonia, Rhizoctonia solani
ABOUT
Infections by the fungus Rhizoctonia solani lead to damping-off, blight, and rot. Typical symptoms include wilted seedlings and eventual death, seed and root rot, lesions on hypocotyls, and cankers on the lower stem.
How to treat?
- Biological
If possible remove and destroy the infected plant with as many roots as possible. Burn it or toss it into the garbage. Do not compost.
Apply ecological products for plant protection (e.g. Trichoderma based products).
- Chemical
If necessary, apply fungicide containing pentachloronitrobenzene (GHS07: Harmful, GHS09: Environmental hazard).
If necessary, apply fungicide containing azoxystrobin (GHS06: Toxic, GHS09: Environmental hazard).
- Disease prevention
Use resistant species and cultivars as well as healthy, certified seeds and seedlings. Avoid planting sensitive crops in infested soil.
Ensure having good soil drainage to avoid overwatering.
Rotate crops. Avoid planting sensitive crops in infested soil.
Plant seedlings in fumigated or sterile soil. Avoid contamination.
Disinfect tools, infected flower pots, and hands to avoid disease transmission.
