Downy mildew is a common fungal disease that affects beetroot plants. It thrives in cool and humid conditions, making it more prevalent in spring and early summer. Here are some symptoms of downy mildew that you should look out for in beetroot:
- Yellowing of leaves: Infected beetroot plants may exhibit yellowing of the leaves, starting from the older leaves and progressing towards the younger ones. The yellowing can be seen as irregular patches or spots on the foliage.
- Downy growth on the underside of leaves: One of the most distinctive symptoms of downy mildew is the presence of a grayish-white downy growth on the undersides of the leaves. This downy growth consists of fungal spores and may appear fuzzy or powdery.
- Leaf curling and distortion: As the disease progresses, the leaves may curl and become distorted. They may also develop a brittle texture and show signs of necrosis (browning or blackening of the tissue).
- Stunted growth: Infected beetroot plants often exhibit stunted growth. The plants may fail to develop properly, resulting in smaller-sized beetroots.
- Reduced yield: Downy mildew can have a significant impact on the overall yield of beetroot. Infected plants may produce fewer and smaller beetroots compared to healthy plants.
It’s important to note that these symptoms can vary in severity depending on the extent of the infection and environmental conditions. If you suspect downy mildew in your beetroot plants, it is advisable to take action promptly to prevent further spread of the disease.
