Tomatoes are perhaps the most beloved culture by summer residents. In order to harvest a good crop, you need to make some effort. Plants need to be fed and watered on time. In addition, of course, preventive measures should be taken, as well as various infections treated. We’ll talk about how to do this best in this article.
Most often, tomato diseases such as late blight, white spotting, brown rot and black leg are found.
Late blight most often affects plants in the second half of the season. Therefore, if your tomatoes are infected with this fungus year after year, it is worth trying to grow early ripe 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 in a row. Tomato diseases such as the black leg and late blight also affect other nightshade nights. Therefore, do not plant them next to the 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 tops are removed and burned. Secondly, you need to treat the plants with some kind of copper-containing preparation.
Brown rot and white spotting are also quite common tomato diseases. In the first case, brown spots form on the plants around the stalk. Over time, the rot spreads inside 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 disease increases with too frequent watering.
White spotting is an infection that affects plant leaves. 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 fetus fades, then this
fungal disease is a tomato - a black leg. Most often, tomatoes growing on acidic soils suffer from such an infection. In addition, excessive moisture contributes to its development. The black leg very rarely infects strong plants, which are well cared for. Compliance with agricultural technology is one of the main preventive measures.
The disease of tomato seedlings, unlike adult plants, is not so common. However, sometimes the seedlings can still disappear. In the event that the leaves begin to turn pale, yellow and dry, you should loosen the soil and put the box with seedlings in a sunny place. If they begin to curl, this may mean that the plants are infected with a viral disease. Treat them with a skim milk solution (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 become ill with a black leg, it is worth spraying with the Fitosporin preparation.
All major tomato diseases are easier to prevent than to treat later. Do not plant tomatoes in the immediate vicinity of potatoes, water, fertilize and weed on time. In this case, the risk of infection will be minimized.
