Carrot Diseases Diseases Common To Carrots and Carrot Plants
|
| Asters yellows is caused by a bacteria that overwinters in perennial weeds and is transmitted to the plant by leafhoppers. Infected plants have yellowish dwarfed leaves that are usually arranged in a tight rosette. Older leaves often develop reddish margins and eventually break off from the rest of the plant. The disease also reduces the size and quality of the roots. The carrots are malformed and develop many hairy secondary roots. Infected roots are tough, off-flavor and lighter in color. There is no control for asters yellows once a plant becomes infected. Therefore, growers must prevent the disease by controlling leafhoppers.

| Alternaria leaf spot is a fungal disease caused by Alternaria dauci. It overwinters in diseased debris in the soil and it may be spread on or in contaminated seed ,or by the wind. The disease usually starts on older leaf margins causing dark spots with yellow borders to develop. Spots on the leaf stems will elongate and kill the entire leaf. Infection most commonly occurs during the cooler portions of the growing season when the leaf moisture does not dissipate as quickly. |
