The vegetable is quite resistant to various diseases, so there are not so many of them. Most of the damage occurs due to fungus or bacteria.
Types of diseases
Let's consider the main diseases:
- It is not difficult to recognize phomosis or dry rot on root crops. Small black dots appear on the carrots, the leaves become brown and black interspersed. To reduce the negative effect of rot, it is necessary to pickle the seeds before planting with potassium permanganate.
- During the growth stage, white rot can be seen, which leads to massive death of the entire crop already during storage. Affected roots begin to become covered with white spots, which become dense and black after a few days. To prevent the spread of infection, it is necessary to reduce watering and dispose of diseased plants from the garden. Experienced gardeners are advised to properly prepare the soil before sowing carrot seeds. In acidic soil, it is recommended to add 200 g of dolomite flour per 1 sq. m. It is important to store the vegetable correctly: the temperature regime in the storage place should not be higher than 10 ° C.
- Black rot is dangerous because it infects the leaves. Initially, brown spots begin to appear on them, and then the disease spreads to the root crop, and it rots. Gardeners can face Alternaria if the summer is wet. Weeds can be the source of the disease, therefore, as a preventive measure, the tops should be burned after harvesting and the area should be cleared of weeds during the period of carrot growth.
- Botrythiosis affects root crops and begins to develop even at the growth stage. As the disease develops on the leaves of the plant, brown spots can be noted, which then turn into a gray-green mold plaque. The causative agent of gray mold lives in the soil, therefore it is imperative to observe crop rotation.
- Wet rot appears when a vegetable grows in a garden bed. Initially, small yellow spots appear on the leaves, and then you can observe water sores that spread over the entire surface.
Today, there are many drugs that help to cope with diseases.
Pests
In addition to diseases, there is a threat to the crop and from various pests:
- Carrot fly affects not only tops, but also root crops. It is not difficult to recognize its presence. Larvae begin to appear on carrots, the roots are empty inside or have back doors that are made by insects. Such a product will not be stored for long. You can defeat the carrot fly by planting carrot seeds early. Experienced gardeners use pepper and mustard to scare away insects, which are scattered between crops as soon as they sprout.
- Leaf flies and aphids are capable of damaging plant seedlings at the initial stage. As a rule, they settle on leaves and stems. It is not difficult to notice their presence, because yellowish spots begin to appear on the leaves of the tops and sticky deposits. The plant stops growing, the root crop becomes crooked. Insecticides will help to cope with these pests.
Proper care of the vegetable will help not only to avoid infection with diseases and pests, but also to harvest a good harvest.
