Often on plants you can observe a strange white coating. And it doesn’t matter if it is indoor flowers, garden or horticultural crops. The presence of whitish powder on the leaves indicates the defeat of their powdery mildew. Behind such a cute name lies a very persistent and tenacious fungus. It hibernates in the remains of plants and with the onset of heat begins to inhabit your plantings. Cucumbers, roses, berry bushes, cereals and ornamental flowers suffer from it.
How to deal with powdery mildew? First of all - prevention. Remove obsolete plant parts in time. Old branches and leaves mercilessly destroy. The soil under the plant is periodically loosened. Do not plant plants too close to each other.
Differences in night and day temperatures (especially their strong fluctuations) exhaust the plants, and adversely affect their ability to effectively resist the fungus. For the same reason, we never water garden crops (in particular, cucumbers) with cold water. Otherwise, they will soon find powdery mildew. Control measures include the introduction of potash fertilizers and superphosphate. It is noted that urea and rotten cow manure, on the contrary, give a green light to the development of the disease. To prevent infection, spray the plantings with Quadris.
If powdery mildew is only outlined on the leaves, treatment begins with the treatment of all parts of the plant with sulfur. Fine powder is placed in a bag of gauze, from which it is then sown on "patients". Pollination needs to be done in calm weather, and then from one gust of wind all your work will go to dust.
Powdery mildew has appeared , the treatment of which by folk remedies includes other recipes, is afraid of ordinary potassium permanganate. But, so that the leaves do not burn, the drug is diluted in a weak proportion: about a half gram of potassium permanganate is taken on a ten-liter bucket of water. We spray the plants with a solution.
There is a rarer way to fight for the health of green wards. This is leaf treatment with whey. It is diluted with water and then applied to plants. As a result, a film forms on them, which prevents the fungus from multiplying. Thus, the development of a disease such as powdery mildew will be stopped. The treatment does not stop there. It is the integrated approach that gives the best results.
Therefore, do not neglect the special means manufactured by industry. Fungicides, which are designed for the prevention and destruction of fungal infections, are highly effective.
At the first signs of the disease, regular treatment with Topaz or Tiovit Jet is necessary.
If your plants have powdery mildew already firmly established on the leaves, we treat them with Tilt, Lepidocide, and Skor. Do not be lazy, carefully spray each leaflet, without ignoring its inner part! It is useful to additionally process the soil.
Remove highly affected parts of the plant. Do not allow the fungus to spread to healthy plantings.
Do not give up, in time taken measures will save your green favorites from adversity.
