Plant disease
Potato leaf infected with a fungal blight.
Aboveground symptoms of root problems often appear similar regardless of the specific underlying cause. These symptoms include:
- Stunting: Reduced growth of leaves and twigs.1
- Foliage issues: Poor foliage colour.1
- Vigour decline: A gradual or sudden decrease in the plant's overall vigour and productivity.1
- Wilting and dieback: Progressive death of shoots starting from the tip and working downward, or general shoot wilting.1
- Plant death: In severe cases, root problems can lead to the rapid death of the entire plant.1
These symptoms can be triggered by various factors, including infectious root and crown rot, feeding by nematodes, insects, or rodents, as well as environmental stressors like poor soil drainage, low temperatures, or mechanical damage to the root system. Additionally, leaf margin scorching can occur as a result of root injury or disease, similar to symptoms caused by nutrient imbalances or excess soluble salts.1
