Tomato late blight: treatment and prevention

Late blight of tomatoes, the treatment of which is a complex process and often does not end in success - the disease is extremely unpleasant and, worse, very common. It will be much more effective to try to prevent it. Preventive measures should be carried out during the entire growing season. First, you must observe a crop rotation. That is, to plant solanaceous - tomatoes, peppers, eggplants and potatoes - in the same place can be only with a periodicity of 3 years.

Deep digging in the fall can also help prevent a disease such as late blight of tomatoes. The treatment of tomatoes should begin immediately after the first signs of the disease are seen. Usually the fungus first affects the leaflets, especially the lower ones. They begin to turn yellow, and then wither. Next, the infection goes to the fruits, which turn black and rot, not having time to ripen. As soon as diseased leaves are seen, they must be immediately ripped off and burned. The tomato plant is burned in autumn in any case, even if the plants are not sick.

You can not also plant tomatoes next to the potato field. Late blight is a disease that affects all Solanaceae. Therefore, if the potato gets sick, tomatoes will also be infected in a few days. Also, you can not plant tomatoes too thick. This greatly contributes to the development of the disease. In the spring it is necessary to cover the bushes at night. This significantly reduces the risk of developing a disease such as late blight of tomatoes. Treatment, as mentioned above, is rarely successful, and protecting plants from sudden temperature changes is one of the most effective preventive measures.

The disease is more often affected by solanaceous in the rainy period. Fungus develops better in dampness. Therefore, one more preventive measure can be considered correct watering. It should not be spent too often. It is only necessary to ensure that the soil under the plants does not dry up. The late blight of tomatoes, measures of which, among other things, consist in periodic spraying with suitable means, very often affects weakened plants. Therefore, the beds must be weeded and loosened in time.

As for spraying, the most safe composition is the infusion of garlic. At the same time, a glass of 10 liters of grated garlic, 2 tablespoons of grated household soap and 2 g of potassium permanganate are taken on a ten-liter bucket of water. Soap is added to ensure that the mixture is better kept on the leaves and fruits. The consumption of this tool is not less than 1 liter per 10 square meters. M. The treatment should be done 2 times a month. This remedy helps even if the plants are already sick. Strangely enough, but the infusion of fermented mushrooms can also prevent such a fungal disease as late blight of tomatoes. Treatment in this case is the same spraying. That is, in the summer, after cleaning the mushrooms for frying, do not throw away the scraps. They leave to wander for several days, dilute the resulting infusion with water (1x10) and treat the plants. By the way, this measure not bad helps and from powdery dew.

Thus, the late blight of tomatoes (photos of diseased plants you can see on this page) is easier to warn than to cure later. Caring for plants correctly, observing all precautions, and you will certainly manage to avoid such trouble.
