Tomatoes are perhaps the most favorite culture of gardeners. In order to harvest a good harvest, you need to make some efforts. Plants need to be fed and watered regularly. In addition, of course, preventive measures should be taken, as well as various infections should be treated. We will talk about how best to do this in this article.

The most common tomato diseases are late blight, white spot, brown rot and blackleg.

Late blight most often affects plants in the second half of the season. Therefore, if your tomatoes become 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 reaches 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 in the same gardenseveral years in a row. Tomato diseases such as black leg and late blight also affect other nightshades. Therefore, you should not plant them next to a potato field.

If you still notice brown spots characteristic of late blight on the leaves, you need to urgently take certain measures.

Firstly, all affected leaves are removed and burned. Secondly, you need to treat the plants with some kind of copper-containing preparation.

Brown rot and white spot are also quite common diseases of tomatoes. In the first case, brown spots form on the plants around the stem. Over time, the rot spreads into the fruit, causing it to die. To avoid infection, it is necessary to strictly control the amount of nitrogen fertilizer applied. Most often, infection occurs precisely with their excess. In addition, the risk of disease increases with too frequent watering.

White spot is an infection that affects the leaves of plants. Spots form on them, which gradually merge, leading 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 darkens and the fruit withers, then this is a fungal disease of the tomato - a black leg. Most often, tomatoes growing on acidic soils suffer from such an infection. In addition, its development contributes to excessive moisture. The black leg very rarely affects the strongplants that are well cared for. Compliance with agricultural technology is one of the main preventive measures.

Disease seedlings of tomatoes, unlike adult plants, the phenomenon is not so frequent. However, sometimes shoots can still disappear. In the event that the leaves begin to turn pale, turn yellow and dry out, you should loosen the soil and put the seedling box in a sunny place. If they begin to curl, this may mean that the plants are infected with a viral disease. They should be treated with a solution of skimmed milk (0.5 cups per liter of water). You can also use "EM-A" plus "Vermistim" at the same time as "Riverma". In the event that the seedlings get sick with a black leg, it is worth spraying with Fitosporin.

All major tomato diseases are easier to prevent than to treat later. Do not plant tomatoes in close proximity to potatoes, water, fertilize and weed in time. In this case, the risk of infection will be minimized.
