Overview

This 2-page publication discusses the symptoms, cause, and control methods for managing alternaria leaf blight.

Alternaria leaf blight, a seed-borne foliar disease of carrots, can decrease crop yield because it reduces the size of the carrots and also weakens the leaves. At harvest, the leaves rip away and the mechanical harvester cannot pull the carrots from the soil. This publication discusses the symptoms, cause, and control methods for managing alternaria leaf blight. (2 pages)
