Diseases of carrots, prophylactics and means of protection
There are many types of carrot diseases that can affect a plant during the entire period of its growth. The main task of the gardener will be to carry out
Thomosis is differently called dry rot , which is caused by a dangerous fungus. The disease affects the plant in the final stages of the growing season. In the initial stages of the disease can be recognized by oblong spots of gray-brown color, which are located on the leaves or petioles.
In addition to damage to the aerial part, fomoz actively develops on fruits and continues its activity during storage, especially when the crop is in a room with air temperature above 10 degrees. Initially, black-brown depressions with a whitish bloom appear on the upper part of the fetus, which gradually grow and affect the whole vegetable.
It is not possible to save the plant, since is almost impossible to cure the disease that has already appeared, , all diseased plants must be removed. As a means of prevention, it is necessary to apply phosphorus-potassium fertilizers before planting and timely remove the tops.
The disease affects the fruits of carrots, which during storage become soft and gradually become covered with white fluffy bloom. The final stage of the 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 of plants with preparations containing copper in its composition. Also must regularly disinfect the storage room .
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 a while, a gray mushroom plaque appears on them.
To protect against the development of white rot, it is necessary to feed the soil with nitrogen fertilizers in time. periodically spray with 1% with a solution of Brodian .It is recommended to store the crop at a temperature of +2 degrees.
The most commonly referred to as this disease is felt rot, it affects the fruit both during active growth and after harvesting during storage I.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 is carried out by spraying plantings with chemicals containing copper oxychloride.
The second name of the disease is black rot. The disease can occur at any stage of plant development. On the young carrots, the main feature is the blackening of the stem. On adult plants, you may notice a 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.
Bacteriosis is one of the most common diseases, and it can be recognized by the following characteristics:
- appears on the edges of the lower leaves, as they expand on the edges of the bottom leaves, as they expand on the edges of the bottom leaves, , which grow on the edges of the bottom leaves, as the surface spreads as the surface grows, as the surface grows, the surface of the surface, on the surface, I go to the surface, I need to go to the surface, I need to go to the surface.
- on the basis of leaf stalks one can observe characteristic gray-white or light yellow drops, , which are called bacterial exudates;
- brown streaks or spots are formed on the stems; ;
- on root crops appear ulcers and brown depressed spots.
It is impossible to get rid of the disease, so the affected landing will have to be removed. Prevention will be keeping seeds before planting in hot water and timely spraying with Hom.
Initially, light brown spots are formed on the leaf plate with the light center of , which gradually grows. 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 measures will be pre-treatment of seeds in hot water and spraying of young shoots with a weak solution of Brodsky liquid.
Brown Spot affects carrots at all stages of development and is therefore very dangerous:
- in young plants appear on the lower part of the stem brown banners. In this case, the carrot sprouts are very often killed;
- Yellow spots of appear on the leaves of adult plants, which 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;
- stalks and stem bases are also affected by this ailment, form on them long brown spots .

Pests of carrots, the fight against them with drugs and folk methods
Pests that live on carrots are very dangerous for planting, this is due to the fact that under the influence of these insects can cause complete death of the plant or its partial dying , which leads to 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 overwinters in the pupae under the ground, which is why the root of the plant most often suffers from such an insect. It is possible to determine the presence of pests by the condition of the tops of ; if a carrot fly is present, the leaves will turn a bronze tinge, after which they dry and die. Damaged carrot pests become unsuitable for consumption.
In order to control and 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 also has jumping legs like fleas. 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.
You can get rid of insects by collecting eggs and processing the plantings with tobacco dust or soapy water.
This insect looks like a small butterfly, is considered a particularly dangerous brown moth, , which infects the testes and the fruit of carrots. You can notice the pest on the cocoons that 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 plantings, that is, to cut off the aerial part of the plant and collect the caterpillars, which must later be destroyed. You can also spray carrots with lepidocide, entobacterin, etc. To prophylactic methods include deep digging of the soil before planting.
Bare slugs are considered the most common pests in the kitchen garden, due to the fact that they live in a variety of places that 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.
For the prevention of the appearance of insects and for the control of them, beds are treated with superphosphate or 10% salt solution.
Wireworm is called the yellow worm, which is actually the 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 with the help of feeding, which includes ammonia. Also well help drugs Aktara and Basudin.
External signs of the appearance of carrot aphids can be seen immediately. On plants, clusters of small green insects are observed. The leaves begin to curl and dry. Such pests feed on stem juice, as a result of which carrots are poorly formed or stopped in development. This factor may adversely affect the yield.
You can get rid of insects by spraying plantings with soapy water, an infusion of ash or tobacco. For prevention in the summer on hot days, carrots are sprayed with warm water as often as possible.
The most serious consequences arise after the appearance of caterpillars of butterflies of this species. They feed on the root part of the stems and directly by the roots themselves, leaving holes and passages behind them.
