White rotCarrot struck white rot
The disease affects the fruits of carrots, which during storage become soft and gradually covered with a white fluffy bloom. The final stage of development of the disease will be the appearance of a crust with black dots.
The fight against the disease occurs through enhanced application of potash fertilizers, spraying plants with preparations containing copper. Also need to regularly disinfect the storage room.
Gray rotGray or Kagatnaya rot
This disease forms a wet rot on the fruit during storage and leads to a large yield loss. Initially, the carrot surface is soaked, after which it darkens and covers the entire area of the fruit. After some time, they appear gray mushroom plaque.
To protect against the development of white rot should be timely feed the soil with nitrogen fertilizers, periodically spray with 1% solution of brodsky liquid. It is recommended to store the crop at a temperature of +2 degrees.
RhizoctoniosisCarrot Rhizoctoniosis or Felt Rot
Most often, this disease is called felt rot; affects the fruit both during their active growth and after harvest during its storageI. Recognize the disease can be on the dark gray internal spots, which subsequently formed a felt bloom of purple hue. At the last stage, black spots appear.
Treatment of the disease carried out by spraying the landings with chemicals containing copper oxychloride.
AlternariaBlack 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.
You can get rid of the disease by spraying with Rovral.
BacteriosisCarrot 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.
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.
CercosporosisCercosporosis 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 spotCarrot 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 flyCarrot 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. To determine the presence of pests can, if the carrot fly is present, then the leaves acquire a bronze tint, after which they dry out and die. Damaged carrot pests become unsuitable for consumption.
As a measure of control and at the same time prevent the occurrence of such insects should promptly plow, loosen and clean the soil from weeds. The chemical treatment of Acclellic, Decis Profi, Tsiper, Sharpay and folk methods also helps well - pouring with liquid ammonia.
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.Carrot Listobloshka
You can get rid of insects by collecting eggs and treatment of planting tobacco dust or soapy water.
This insect looks like a little butterfly, brown moth is considered especially dangerous, which affects the testes and the fruit of carrots. You can spot a pest by the cocoons it weaves. The plant gradually darkens and begins to dry. The umbrella mole most often occurs at the end of June - mid-July, after which it turns into a pupa and does not pose a threat to the future harvest.

In order to get rid of insects it is necessary to mechanically clean the planting., that is, cut off the aerial part of the plant and collect the caterpillars, which must subsequently be destroyed. You can also spray carrots with lepidocide, entobacterin, etc. To prophylactic methods include deep digging of the soil before planting.
Bare slugsBare slugs
Bare slugs are considered the most common pests in the gardenThis is due to the fact that they live in a variety of places, which include soil, turf, fallen leaves, stones or any other area with high humidity.
Both adults and young slugs can cause serious damage to yields. They are actively eating the leaves and eating large pits in the fruits themselves.
To prevent the appearance of insects and to combat them beds are treated with superphosphate or 10% salt solution.
Wireworm is called the yellow worm, which is actually a larva of the click beetle. On average, the length of such an insect is 3 centimeters.. The wireworm feeds on roots, eating them and leaving characteristic point passages. In this case, the vegetables will be unsuitable for human consumption.
It is possible to get rid of such pests by means of top dressing., which includes ammonia. Also well help drugs Aktara and Basudin.
Carrot aphidCarrot 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. Such pests feed on stem juice, as a result of which carrots are poorly formed or stop developing. This factor may adversely affect the yield.
You can get rid of insects by spraying plantings with soapy water., infusion of ash or tobacco. For prevention in the summer on hot days, carrots are often sprayed with warm water as often as possible.
The most serious consequences occur after the appearance of butterfly caterpillars.related to this species. They feed on the basal part of the stems and directly by the roots themselves, leaving holes and passages behind them.

In carrots, a disease or a pest can often be found, which is why you need to carefully inspect the beds and the harvest at the time of defects and omissions. In order to face such a problem as seldom as possible, it is necessary to follow the rules concerning agricultural engineering and plant processing.
