What is late blight
Phytofto) is a real plague for cultivated plants, which was brought from America in the 30s of the XX century. The disease affects potatoes and tomatoes, and destroys them. Despite the fact that since the appearance of this disease, a whole era has passed, it has not yet been possible to get rid of it.
What is late blight
Currently, many varieties of potatoes and tomatoes have been derived, which are relatively resistant to late blight, but they are not 100% protected from it.
Phytopher is a fungal disease that spreads very quickly. Infection usually comes from previous stands. If this infection flourished before on the site, then the risk of a new outbreak of the disease is quite high. The mushroom of late blight is preserved in the soil for a year, which means with planting tomatoes and potatoes at this place to wait for a time.
What is late blight
Outbreaks and the rapid development of late blight are observed in cool and rainy weather, as well as where plants are planted too often. So that the disease does not progress, it is necessary to immediately get rid of stepsons on tomatoes and tie bushes.
Initially, phytoft) always affects potatoes. You can recognize it by dark brown spots with a grayish plaque on the plant. At first, marks appear on the lower leaves, then stalks and flowers blame and dry out and dry out, after which there is a damage to the tubers. Gray and brown clear spots appear on them, different in size. Phytofto) can develop long before flowering. In this case, the plant immediately turns yellow and dies.
Tomatoes are already infected from potatoes. At first the leaves suffer in the same way, then the infection passes to the fruits.
In general, potatoes and tomatoes need to be planted separately from each other, then the risk of infection of cultures will be minimal. The first signs of late blight must be stopped with a 10% solution of salt. If plants are treated with them, then a film appears on the fruits that will not allow infection to spread. When the defeat is quite strong, it is better to collect and destroy the fruits. Minimum damage can be cut out, and the fruits are put on home blanks.
You can warn late blight if you soak the seeds in a potassium permanganate solution for 20 minutes before sowing, and then rinse well with water. Before planting, plants can be treated with a 0.5% solution of burgundy fluid or copper chlorosa, in a ratio of 40 g per 10 l of water. From late blight helps with oxich – 2 tablets (or 20 g) per 10 l of water.
For convenience and the best effect, the solutions are sprayed through the spray gun on the entire plant, carefully processing both the lower and the upper side of the leaves. Such processing is enough for 10-12 days. Pathogenic bacteria quickly die, falling on a protected plant. 10 days after processing, the fruits can be eaten.
In the rainy and cold summer, late blight can be especially rampant. In such years, it is quite difficult to fight the gardeners, unable to cope with this task, prefer to relieve fruits with unripe, to reconcile. Green and brown – they are very prone to late blight. Red fruits are resistant to this infection.

Recharge helps to maintain the crop, but there is also its underwater stones. On green fruits removed from a sick bush, after some time, spots of late blight may appear. Therefore, having collected tomatoes, it is better to lower them in hot water for 2 minutes. The water temperature should not exceed 60 degrees. After such simple processing, the fruits are wiped dry and laid out in a dark room. So that the fruits are spicy quickly, they are interspersed with red, and then covered with an old blanket or something else. The room where tomatoes ripen should be dry and warm.
The remains of affected plants must be burned or burying to a depth of at least 0.5 meters. In no case should you add a sick vegetation to compost, otherwise you can’t get rid of the infection.
