The 6 best-known carrot diseases
1. Bacterial rot
Rotting pathogens are often seen especially in waterlogged conditions, including the bacterial rot.
In the case of bacterial rot, the carrots have sunken spots, which are also watery. Over time, these spots turn brown and begin to rot. Once it has come to an infection, the pathogens spread quickly. Even with the storage of vegetables, the rot can spread further.
Infested fruit must be destroyed immediately and in no case stored. If the infestation is very strong, you should not grow carrots for three years.
2. Powdery mildew
The powdery mildew is very common in native gardens, so he can also attack carrots.
On the surfaces of the leaves there is a white coating, reminiscent of flour, hence the name. Gradually, the carrots are deprived of vital nutrients, so that they can not develop well and subsequently be able to enter.
The infested plant parts should be removed immediately. Only water the plants in the root area so that the leaves do not get wet. You can combat the powdery mildew with home remedies such as a nettle, skim milk, a detergent-oil mixture or horsetail.
3. carrot red
If it comes to an infestation with the so-called Möhrenröte, so you have no chance of success in the local garden, as far as the fight.
It is thought that the pathogen is transmitted by the gray-winged louse, so you should prevent it as far as possible by removing it from the garden as far as possible. The leaves turn yellow in the course of the disease more and more, later they turn red and stunted. It is noticeable that the leaf veins remain green. At the roots it comes to bearded formations. These, too, wither away with time.
4. carrot black
A fungus is also responsible for this disease of the carrots.
The carrot blackened can be recognized by the fact that on the leaves dark spots form, which have a yellowish border. In case of heavy infestation it comes to the drying up and finally to the death of the leaves. If young plants are affected, it can lead to a complete failure of the harvest. The carrots do not develop properly when the leaves are attacked by the fungus.
Can not fight directly the carrot black. But you can save your carrots from further infestation by destroying infested plants immediately. You should also refrain from growing carrots for at least one year as the mushroom can survive in the soil for a long time.
To prevent carrot blackening, select the best resistant varieties and do not plant them too densely. The cultivation in a windy location has also proved itself.
5. Black rot
This fungal infection first affects the root, which turns black. In young seedlings, however, it may also lead to a discoloration of the leaf approaches.
The affected plants should be removed immediately. In order to prevent the black rot it is important to pay attention to a dry soil, sufficient planting distance and a windy location in the garden. Fertilization with nitrogen can also promote black rot infestation.
For prevention, no celery or parsley should be planted in the immediate vicinity of the carrots.
6. Violet Rootbroken
The Violet Wurzeltöter is also a fungal disease, you recognize him on thick, purple growths on the carrots. It quickly comes to rot and dying of the plant. The host plants of this pathogen include, for example, beets, celery, parsley, chicory, asparagus and potatoes.
In the soil, the fungus can survive for several years and lead to new infections. Warm and constantly moist soils and strong weed formation favor such infestation. Infested plants must be destroyed immediately. You can prevent it by an optimal crop rotation. The cultivation of the corresponding host plants should be avoided.
