Radishes are susceptible to a wide variety of diseases. Although radishes seem to most gardeners to be quite easy to care for, getting a good harvest can be overshadowed by the presence of diseases.

The most common diseases of radish include mucous bacteriosis, white and gray rot, phomosis, dry and heart-shaped rot, ordinary mosaic, powdery and downy mildew, black leg and fusarium.

To combat diseases, compliance with the norms of crop rotation in the summer cottage will help. The radish itself is the crop that is capable of producing a harvest in about one month. Therefore, many summer residents neglect the rules of crop rotation. For one season, it is forbidden to plant radishes in the same place, although some summer residents do just that. Planting radishes in the places where cabbage used to grow is very undesirable. The best predecessors of this crop are onions and garlic, potatoes and tomatoes, cucumbers and beans.

As for pests, the most common are the so-called cruciferous fleas. This parasite is a small dark-colored bug that can jump from place to place rather quickly. These fleas will make holes in the leaves of the radish, thereby damaging this plant. In the case when the spread is quite large, then the development of the plant stops, which ultimately leads to the death of the radish. The root crop will not ripen, and its size will remain very small. This pest is especially dangerous for radish seedlings. If these fleas infect crops, then they can be almost completely destroyed. But adult plants can resist this pest for a long time. Dry, hot weather provides an excellent breeding ground for this pest. If you plant radishes early enough, you can get a wonderful harvest even before these flea beetles appear.

Biological control methods are the best methods for such a pest. The first method is to spray the radish leaves with a solution of wood ash. You can prepare the solution as follows: for ten liters of water, you need to add about two glasses of ash and about fifty grams of laundry soap. The resulting mixture is thoroughly mixed. However, many gardeners choose the easier way. Ash is taken on a shovel and it spreads over the bed. Actually, after such measures, for some time these fleas cease to function and parasitize. You can do the same thing, only replace the ash with tobacco dust.

With regard to chemical methods of control, then here you can choose the treatment with one of the types of insecticides. It should be remembered that this can be done for so-called medium-sized radishes, as well as for young seedlings. And only in that case, such measures are permissible when the danger of destroying the entire crop is very high.

You can also use a mechanical method to combat this pest. To do this, you need to cover the radish with agrospan. If the air temperature is not very high, then fleas in this case will not appear. When the seedlings have already grown, this material is removed. Further, in order to combat cruciferous flea, ash can be used.

It should be noted that drip irrigation is optimal for radishes. Other methods of watering can lead to the fact that all the nutrients are immediately washed off the leaves. In this case, the flea can again begin to parasitize.

Another important pest for this plant will be the white beetle. Such a parasite is a white butterfly with a rather dark edging along its wings. Chemicals should not be used to combat this pest. The following method is suitable: the beds with the plant are treated with a solution made from mustard, ground pepper and salt. For a ten liter bucket, two tablespoons of mustard and salt are taken, as well as one spoonful of red or black pepper.
