Crown Rot

High

Crown rot is a serious fungal disease that attacks the crown (base) of the plant where the stem meets the soil. It is caused by various fungal pathogens including Phytophthora, Fusarium, and Rhizoctonia. The disease thrives in waterlogged conditions and can quickly spread to kill the entire plant if not addressed promptly.

Anthracnose

High

Anthracnose is a fungal disease caused by fungi in the genus Colletotrichum that affects many plants, including vegetables, fruits, and trees. The disease thrives in cool, wet conditions, causing dark, sunken lesions on leaves, stems, flowers, and fruits.

View solution

Bacterial Soft Rot

High

Bacterial soft rot is a destructive plant disease caused primarily by bacteria from the genera Pectobacterium (formerly Erwinia) and Dickeya. These bacteria produce enzymes that break down plant cell walls, causing rapid and foul-smelling tissue decomposition. It mainly affects succulent tissues such as tubers, fruits, stems, and bulbs, being especially problematic in warm and humid conditions.
