Black root rot
Black root rot (Thielaviopsis basicola) is a fungal pathogen. It was first detected in Colorado in 1984.
This is a soil fungus that attacks more than 100 plant species in 33 families. Members of the Fabaceae, Solanaceae, and Cucurbitaceae families are especially affected by T. basicola. The common name 'black root rot' is based on darkly pigmented chlamydospores that form in the root cells of hosts and giving a 'blackened' appearance to the root tip.
