Late blight disease of tomatoes and potatoes
Late blight disease of tomatoes and kartofelevodcheskaya, vzdelanie brings the fruits and the vegetable garden. The beginning of the month — the height of the harvest, and caring hosts in a hurry not to miss any opportunity to fill their bins. But at the same time, along with cold roses come in the garden and their diseases and certain pests. If August does not indulge warm days, vengeance played late blight. Especially goes potatoes. This disease can hide in the ground and planting material, and then transferred and tops. The old way to save the potato crop — the first small outbreak to hold soil to protect the tubers. Unfortunately, in rainy weather it helps a little. You can spend and spraying of foliage with a solution of copper sulfate or other copper-containing drug.
Most importantly, do not be lazy and cut the sick leaves two weeks before harvest. But I, as an agronomist, I advise you, especially if you are many years see his part of late blight, it means that the soil is contaminated, change the seed. And not just to change, and select the fitoftoroustoychivyh varieties, at least for the tubers. Testing on the site about fifteen varieties of our Dutch breeding, I saw among the slain Phytophthora varieties were green resistant varieties. I especially liked the variety of the Magician, though our old cultivar Lugovskoy was struck by one of the last. So: the infected leaves should be burned. It is by no means impossible to put in the compost, otherwise you’ll make so that you not plant potatoes and late blight. We should not forget that this disease affects all plants in the family Solanaceae. And if the flower bed sick your favorite fragrant tobacco, there is no choice. The diseased plants should be removed and destroyed in order to stop the spread of infection. Not necessarily that late blight begins to spread, starting with potatoes. And it can start a tomato greenhouse. After all, it created «ideal» conditions — heat, wet, and sometimes the plants are planted too densely. If you suddenly notice on the leaves of tomatoes, brown spots, and, turning the sheet, I discover whitish plaque — off this sheet into the fire. After inspecting all the plants and picking the affected leaves, you need to process the tomatoes with a solution of copper sulfate according to instructions. The same solution can be shed and the ground between the bushes. It is important to reduce humidity in the greenhouse. To do this on a hot day, open all doors and Windows. And if that doesn’t work, you will have to do under the roof curtain of non-woven material, which will remove drops from the top. Tomatoes late blight affects both the foliage and green fruit. Gardeners argue that even a healthy looking green fruit from infected plants is not suitable for conservation. But for ripening them can still be saved. Some gardeners warm up harvested green tomatoes in the Russian stove or oven for 3-4 hours at 40°C. Other prefer a faster way: they put the fruits in water at a temperature of 60°C for 1 -2 seconds and obsesiv fruit, lay them in storage. Personally, I only used the method of warming, and that at the Russian stove, and not in it. But it seemed to me effective ways of relaying the fruits rjabinovyj leaves and dried and crushed birch chaga. Moreover, pickled green tomatoes from the affected bushes came to my liking. And.
