Carrots are susceptible to diseases like Violet Root Rot (Rhizoctonia Crocorum), Cavity Spot (Pythium Violae), Root Knot Nematodes (Meloidogyne Species), and Crown Rot (Rhizoctonia Solani).
Violet Root Rot
Violet Root Rot is a fungal disease, which severely affects carrot crops. Often starting out as a superficial purplish rot, the disease progresses through increasingly severe stages before rotting the carrots completely.
Cavity Spot starts out as harmless looking pinhead sized spots along the carrot. This rapidly develops into small lesions surrounded by a yellow halo in the month or so before harvest, leaving them in no fit state for market.
Root Knot Nematodes
Root Knot Nematodes are tiny ‘eelworms’ that live in the soil, invisible to the naked eye. These Nematodes use the roots of carrots as their nurseries, entering through the root tip leading to above ground stunting and yellow, as well as the formation of Galls on deformed, stunted roots.
Crown Rot Disease commonly appears in wet and heavy soils, infecting the roots of carrots near maturity. The fungus causes dark brown sunken lesions near the crown of the vegetable, and can lead to damping-off of carrot seedlings.
