Carrot

“The fungus eventually colonizes the entire cabbage head. Below: White mold on cabbage head with sclerotia. (M.T. McGrath) Other susceptible crops, most of which have been seen affected by white mold in New York, include other brassica crops, carrot, eggplant, lettuce, pepper (see below), potato, tomato, pea, pumpkin, and winter squash, plus hemp (see below) and soybean.”

“Lettuce, cabbage, tomato, carrot, brassicas, and snap beans are among the most susceptible and should not be grown on land known to be contaminated with Sclerotinia. After an episode of disease, rotate away from susceptible crops for 7 years.”

“D, Cucumber can be infected with canker from soil containing diseased remains of carrots or turnips (36).”

“This mycoplasma-like pathogen causes distortion and discoloration of leaves and stunted, hairy, and bitter roots in both carrots and parsnips. Lettuce, celery, celeriac, parsley, corn, and potato are also susceptible.”

“These diseases appear very similar in the field, making identification difficult; however, treatment methods are the same for all three. Use certified, disease-free seed or treat seed with hot water or fungicides. Rotate with crops outside of the Apiaceae family.”

“Carrot Rust Fly (Psila rosae) While principally considered a pest of carrots, carrot rust fly can also damage parsnips, celery, celeriac, parsley, and dill as well as weeds in the Apiaceae family.”

“Tarnished plant bugs feed on over 350 types of plants, including asparagus, beans, beets, carrot, cauliflower and broccoli, potato, tomato, peaches, strawberries, and ornamental plants.”

“any 2-year sequence involving carrot, celery, and potato should be avoided due to root-knot nematode (Meloidogyne hapla) (20).”

“Continuous cropping of potato will also increase incidence of the disease. When planting susceptible varieties, avoid fields with a history of scab. When scab is present, rotate out of potatoes for at least 2 years. Beets, carrots, radish, and some weeds can also be hosts.”

“It has a wide host range. Potatoes, beans, lettuce, and cabbage are among the most important hosts. Other hosts include broccoli, kale, radish, turnip, carrot, cress, cucumber, eggplant, pepper, tomato, and sweet potato.”

“Allelopathic effects usually taper off after about 30 days. After killing rye, it’s best to wait three to four weeks before planting small-seeded crops such as carrots or onions. If strip tilling vegetables into rye, be aware that rye seedlings have more allelopathic compounds than more mature rye residue. Transplanted vegetables, such as tomatoes, and larger-seeded species, especially legumes, are less susceptible to rye’s allelopathic effects (117).”

“The study also revealed more misshapen carrots and a higher population of Pythium when barley preceded carrots, but the barley residue may not have decomposed sufficiently before the carrots were planted.”

“broadleaf weeds have time to set seeds in a grain crop before harvest, which is particularly a problem in noncompetitive or difficult-to-cultivate crops like onion and carrot”

“White Mold (Sclerotinia sclerotiorum) Fluffy white mycelium and black sclerotia distinguish this disease from other crown and root rots of carrots. The sclerotia can survive for many years on the soil. Rotate with small grains.”
