Treatment of the disease carried out by spraying the landings with chemicals containing copper oxychloride.

Alternaria

Black Rot (Alternaria)

The second name of the disease - black rot. The disease can occur at any stage of plant development. On young carrots, the main feature will be the blackening of the stem. On adult plants, you can notice the twisting of the leaves, which eventually turn yellow and dry. Petioles limp and lean to the ground. Dry black mold forms on the surface of the fetus.

Black rot can spread both through the soil and through the seeds. The disease can in a short time to destroy most of the landings.

You can get rid of the disease by spraying with Rovral.

Bacteriosis

Carrot bacteriosis or wet rot

Bacteriosis is one of the most common diseases, and can be recognized by the following features:

  • on the edges of the lower leaves appear yellow spotswhich darken as they grow, but at the same time retain yellow outlines around them;
  • on the basis of leaf stalks one can observe characteristic gray-white or light yellow drops, which are called bacterial exudates;
  • on the stems are formed brown streaks or spots;
  • on root vegetables ulcers appear and brown depressed spots.
If the disease has managed to spread strongly, then the plant will begin to emit a sharp and unpleasant smell.

It is impossible to get rid of the disease, so the affected landings will have to be removed. Prevention will be keeping the seeds before planting in hot water and timely spraying with Hom.

Cercosporosis

Cercosporosis on carrot leaves

Initially light brown spots with a light center are formed on the sheet platewhich is gradually expanding. The edges of the leaves begin to curl. If the humidity is increased, the spots will be covered with bloom. On petioles and stalks of education oblong. Subsequently, the green part of the plant dies completely, and the fruits become small and lose their original shape.

Preventive treatment of seeds will be preventive measures. in hot water and spraying the young shoots with a weak solution of Brodsky liquid.

Brown spot

Carrot leaves are affected by brown spot

Brown spot affects carrots at all stages of development and is therefore very dangerous:

  • young plants on the bottom of the stem appear brown banners. In this case, the carrot sprouts die very often;
  • on the leaves of adult plants yellow spots appearwhich gradually turn brown or black, but the original shade remains as a halo. With increased humidity on the spots you can see the characteristic black bloom;

Pests of carrots, the fight against them with drugs and folk methods

Pests living on carrots are very dangerous for planting, this is due to the fact that under the influence of these insects may be the complete death of the plant or its partial deathwhich leads to a loss or decrease in yield. The fight against insects should be started immediately, after their detection, in this case there will be much more chances to get rid of them.

Carrot fly

Carrot fly

The carrot fly hibernates in the pupae under the ground, which is why the plant root crop most often suffers from such an insect.

Listobloshka

Listobloshka is a very small insect, which, like fleas, has jumping legs. Females of such pests lay eggs on carrots. Soon from the eggs appear the larvae, which in turn will begin to feed on the sap of the leaves, thereby causing the plant to dry completely.

To prevent the appearance of insects and to combat them beds are treated with superphosphate or 10% salt solution.

Wireworms

Wireworm

Carrot aphid

External signs of the appearance of carrot aphids can be seen immediately. There are clusters of small green insects on plants.. The leaves begin to curl and dry.
