Strawberry diseases: descriptions with photos and methods of treatment
On the way between you and the fragrant harvest of ripe strawberries, diseases regularly become. Most often, these are fungal lesions that appear due to improper care, bad weather, pests or other plants. But the whole plantation can die in a matter of weeks! It is better to meet the problem fully equipped, so we have already prepared a description of the disease with photos and figured out treatment options!
A dangerous fungus affects the entire strawberry plantation and other crops in the neighborhood. Rainy but warm spring days are very favorable for him. Brown cracking spots appear on the leaves, ulcers on the shoots, the roots rot, and the fruits become covered with dark spots and mummify.
The fungus is very resistant to drugs, so prevention is in the foreground. Keep the distance between the beds, apply immunomodulatory top dressing in time, spray the strawberries with Bordeaux liquid or sulfur-based preparations twice until the ovaries appear. Fungicides such as Metaxil, Antracol or Quadrice are used for treatment.
Over a month and a half, the diseased plant gradually fades and completely dies. And during this time it affects other beds of strawberries, berry bushes and garden crops.
It is important to process all the seed, to plant only healthy seedlings, to make potassium and lime on time. For the treatment of the disease, use Fundazole, Benorad, Nitrofen and similar drugs.
This is a common fatal fungus that is tolerated in almost every possible way. It affects the root system, due to which the bushes stop growing, the lower leaves darken, and individual shoots blacken and die. For prevention, the most important thing is to maintain the immunity of strawberries.
Be sure to cultivate the roots before planting, adhere to the principles of crop rotation, choose even sunny areas for strawberry beds. Avoid the proximity to potatoes and do not use potato compost. Before planting seedlings, treat the site with Gamair, Extrasol or similar preparations.
4. White rot
The fungus outwardly resembles ordinary mold, because the berries are covered with fine whitish fluff. It affects almost all berry crops, but especially strawberries and strawberries. It is fundamentally important to immediately cut and destroy all affected plants.
Be sure to treat the seed with antiseptics and plant only healthy sprouts. Keep the distance between the beds so that there is always an influx of fresh air. Use specialized chemicals like Derosal for treatment.
5. late blight
This disease is fatal in the first place for the root system, and bring it along with seedlings. First, the lower leaves wither, then the strawberry bush begins to grow from bottom to top from the root itself. At the very end, young and weak shoots darken and die.
Change the place of planting of strawberries, do not plant it on the beds after potatoes and do not condense the plantation. Treat seedlings with Fundazol, Fitosporin, Trichodermin or their analogues. For the treatment of the disease, more stringent drugs are needed - Ridomil, Quadris, Profit and others.
6. White spotting
It is very easy to identify the disease by the appearance of characteristic white spots with a dark, brown-purple border. A little later, cracks and holes appear in their places. The disease manifests itself towards the end of summer or autumn and affects various garden and ornamental cultures.
For prophylaxis, treat the strawberries several times with copper-containing preparations with a weekly interval until the ovary appears. Before flowering and after harvest, use Bordeaux fluid. For treatment you need specialized chemicals - Falcon, Switch and others.
7. Gray rot
Although many fungi are called “rot” in one word, their pathogens are completely different. This one, for example, prefers cool, windy and rainy days. At such a time, the leaves dry, and the berries darken and are completely covered with gray mycelium fluff literally in a couple of days.
Do not allow excessive thickening of landings - there must be a distance for ventilation. Observe crop rotation and change the place of planting strawberries every couple of years. In rain, cover the plantation with foil, and in case of infection, immediately treat it with Bordeaux liquid, Derozal, Topsin M or similar fungicides.
