Let's continue to consider diseases and pests of radish.

Getting Started - Part 1.

A disease such as bacteriosis is characterized by the fact that the roots themselves acquire a slimy appearance, and an extremely unpleasant smell of rot begins to emanate from them. The leaves of the radish will also begin to turn yellow. In order to combat such a disease, it is recommended to use the treatment of a diseased plant with one percent Bordeaux liquid.

There is also such a disease as keela. In diseased plants, the leaves begin to turn yellow and wither over time. At the same time, various swellings and growths become noticeable on the surface of the root crop. This disease belongs to the category of fungal: in order to combat, the soil around diseased plants should be watered with milk of lime. You can prepare this mass as follows: take ten liters of water, where you should dissolve two glasses of the so-called fluff lime. Watering one plant will require one liter of this solution.

The next known and dangerous disease will be the black leg. This disease affects young plants in particular. A characteristic of such a disease will be that the leaves will begin to curl and their color will turn yellow. On the base of the plant stems, a very noticeable blackening will appear. As a control method, a special solution should be prepared. To do this, you will need to dissolve a tablespoon of copper sulfate in combination with forty grams of laundry soap in ten liters of water. The resulting solution must be sprayed on those plants that have already been affected by the disease. Spraying with a tincture made from onion husks will also be a good way. Such a solution is prepared as follows: approximately twenty grams of husk is taken per liter of water and this mass is infused for a day. It is necessary to hold such events a couple of times with an interval of about six days.

It should be noted that even when choosing the varieties of radish that you plan to plant in the future, it is very important to choose the right varieties. The optimal solution should be those varieties that have increased resistance to a variety of diseases. Preventive measures themselves are the best way to prevent the occurrence of various diseases and the appearance of pests in the future.

A disease such as gray rot most often attacks the crop already during storage. Correct care of the radish and careful selection of the crop, which is planned to be left for storage, will allow to avoid this disease.

The radish mosaic belongs to the category of viral diseases, the plant slows down its growth and intense leaf deformation is observed. To combat and prevent such a disease, it is very important to observe the norms of crop rotation.

Powdery mildew is another important disease. It will affect both leaves and petioles and stems. A powdery bloom appears on the surface of the diseased plant, over time it turns into a light brown. The upper side of the leaves is most susceptible to this disease. A diseased plant will be very lagging behind in development and growth. With regard to control measures, first of all, it is necessary to observe the crop rotation. Radish crops should be at a sufficient distance from other crops. It is recommended to treat the seeds with special preparations that can prevent the development of such diseases.

Downy mildew becomes noticeable on the leaves of plants: here the appearance of small specks is noted, which over time acquire light yellow tones, and then also turn brown, a grayish-purple bloom appears on the underside of the leaves. Blackening of the roots of radish is also sometimes observed. Actually, grayish-blue spots become noticeable on the roots. In order to combat these diseases, plant debris should be destroyed, as well as regular soil disinfection.
