The most common diseases of tomatoes

Tomatoes - almost the most favorite summer residents culture. In order to harvest a good harvest, you need to make some effort. Plants must be fed and watered on time. In addition, of course, should be carried out preventive measures, as well as treat all kinds of infections. On how best to do this, and talk in this article. Most often there are such diseases of tomatoes as late blight, white spot, brown rot and black leg.

Phytophthorosis most often affects plants in the second half of the season. Therefore, if your tomatoes are infected with this fungus from year to year, it is worth trying to grow early ripening varieties. In this case, you can harvest before the infection gets to the fruit. In order to avoid the development of late blight, it is also worth taking some preventive measures. First of all, you need to remember one simple rule - you can not grow tomatoes on the same bed for several years. Such diseases of tomatoes, like black leg and late blight, affect other solanaceae. So do not put them next to the potato field.

If you still notice on the leaves characteristic for late blight brown spots, you need to take certain measures urgently. First, the entire affected tops are removed and burned. Secondly, you need to treat plants with some copper-containing drug.

Brown rot and white spotting are also quite frequent diseases of tomatoes. In the first case, brown spots form on the plants around the stalk. Over time, rot spreads into the fetus, as a result of which it dies. To avoid infection, it is necessary to strictly control the amount of nitrogen fertilizers applied. Most often, infection occurs precisely with their excess. In addition, the risk of the disease is increased by too frequent waterings.

White spotting is an infection that affects plant leaves. On them spots are formed, which gradually merge, lead to the death of tissues. Preventive measures taken to reduce the risk of infection are identical to those used in the prevention of late blight.

If the root neck becomes dark and the fetus fades, then this fungal disease is a tomato - a black leg. Most often from such infection suffer tomatoes, growing on acidic soils. In addition, its development contributes to excessive moisture. The black leg is very rarely affected by strong plants, followed by good care. Compliance with agricultural technology is one of the main preventive measures.

The disease of tomato seedlings, unlike adult plants, is not a frequent phenomenon. However, sprouts can sometimes disappear. In the event that the leaves begin to turn pale, turn yellow and dry, you should loosen the soil and put the box with the seedlings in a sunny place. If they start to twist - this could mean that plants are infected with a viral disease. It should be treated with a solution of skim milk (0.5 cups per liter of water). You can also use "EM-A" plus "Vermishim" simultaneously with "Riverma". In the event that the seedlings fall ill with a black leg, it is necessary to spray with "Fitosporin".

All the basic diseases of tomatoes are easier to prevent than to treat later. Do not plant tomatoes in the immediate vicinity of potatoes, water on time, fertilize and weed. In this case, the risk of infection will be reduced to a minimum.
