Types of Swiss Chard Diseases and Their Signs

Swiss Chard Blight

Swiss chard blight is one of the most common diseases that affect Swiss chard plants. It is caused by the fungus Rhizoctonia solani, which attacks the root system and causes wilting, yellowing, and chlorosis of leaves. In severe cases, the fungus can cause the plant to die.

Leaf Spot Disease on Swiss Chard

Leaf spot disease on Swiss chard is caused by the fungus Cercospora beticola. The fungus causes small, circular lesions with a tan center and yellowish margins to form on leaves. As the infection spreads, the spots merge, and the leaves become necrotic.

Cercospora Leaf Spot on Swiss Chard

Cercospora leaf spot on Swiss chard is also known as pink rot due to its pink appearance in its early stages. It is caused by the fungus Cercospora pigment. As the infection progresses, the pink spots turn grayish-brown and grow to an irregular shape.

Downy Mildew on Swiss Chard

Downy mildew on Swiss chard is caused by the water mold-like organisms Peronospora farinosa f. sp. Spinaciae. Lesions form on leaves' surfaces, initially appearing as pale green or yellow. These later turn brown with a blue-grey downy growth underneath.

Fungal Infections on Swiss Chard

Fungal infections on Swiss chard are caused by various fungi that can attack the plant's leaves, stems, or roots. The symptoms may vary, but some common signs include brown spots or patches, stunted growth, and deformities in growth.

How to Prevent and Manage Swiss Chard Diseases

Preventing Swiss chard diseases is always better than trying to manage them. Therefore, it is essential to take good care of your plants by planting them in healthy soil, watering them adequately, and keeping the garden clean. If your plants are already infected, you can try removing the diseased parts or seek treatment from an expert.

Where to Get Help If You Suspect Swiss Chard Disease Is Present
