Crater Rot Carrot Causes

What causes crater rot carrot? What is the most common cause of crater rot carrot?

Rhizoctonia carotae is a fungus that causes crater rot. The hyphae of R. carotae are hyaline and thinner (4–5 μm) than the hyphae of most other Rhizoctonia species. In addition, most septa have clamp connections. This stage of the pathogen is not considered a true Rhizoctonia species because of how it looks. The fungus makes sclerotia, which start white but turn brown as they mature. They are 1–3 mm in diameter and are made up of groups of mycelium. On the surface of the carrot, the sclerotia grow in groups. Athelia arachnoidea, the perfect stage of a basidiomycete, is not known to play a role in the development of the disease.

Crater Rot Carrot Disease Cycle

Even when stored at 1–3º C, mycelium spreads from root to root. High humidity and moisture in the air make disease spread easier. The pathogen spreads through the soil, and it is thought that some infections happen in the field before the crop is picked. It is thought that mycelium on the crown or roots starts an infection when the plant is kept in a cold place. The pathogen can also live in storage bins made of wood.
