Strawberry diseases: description, signs
Strawberry diseases: description, signs
Gray rot on strawberries
This fungus begins to show its activity during the flowering of plants and during the ripening of the crop. The causative agent of this disease is the fungus Botrytis, very damp and rainy weather contributes to the occurrence of this disease. As soon as the plant is infected, its leaves begin to become covered with spots of brown or gray color, a fluffy bloom forms on the spots. If you do not take action and do not treat the plants, the crop will die. The berries affected by the fungus dry up.
Treating ramulariasis
This fungus attacks the roots and stems of strawberries. The plant gradually becomes covered with white spots, over time the spots become larger and spread throughout the entire bush. At the beginning of the disease, the spots have a red-brown tint, the more advanced the disease, the darker and larger the spots become.

The fungus of brown spot appears on the leaves of the plant, it mainly affects old or sluggish shoots. The leaves are covered with large brown spots, if not treated, the spot will begin to grow overgrown with black spores. Infected leaves dry very quickly and fall off.
How to deal with verticillary wilting
If a strawberry is infected with verticillium wilt, its leaves will infest fairly large dark spots. Gradually, necrosis develops on the diseased plant. At the very beginning, only old leaves die off, but over time, the disease can destroy the entire plant. This fungus from the leaves goes into the root system, and turns the root into dust. After the invasion of this disease, it is impossible to plant young and healthy strawberries in this garden. The soil requires total disinfection, since the fungus is perfectly preserved and continues to develop in the soil.
Phytophthora
Oddly enough, this disease has two forms. One is chronic, the other is transient. With a transient form, during the beginning of the growing season of the plant, the peduncle or the whole bush dies. The roots weaken and begin to bare, a reddish bloom appears on the longitudinal section. If Fusarium is chronic, the plants grow very slowly, the leaf becomes small and cup-like, and the color of the foliage turns gray. The leaves dry and fall off, the strawberry mustache ceases to let in at all, the ovary is completely absent. The plant dies for a very long time, it takes about three years.
Diseases of strawberries: a description of powdery mildew, its consequences
This fungus spreads to the leaves and berries of strawberries, the focus of infection usually occurs in damp and cool weather, especially if the strawberry garden is too thick.A gray bloom forms on the plant, the leaf takes the form of a tube, on the back the leaf is covered with a pink bloom. Diseased berries look like they have been sprinkled with flour on top.
Rust on the leaves
Rust begins to develop in early spring. The focus of infection usually occurs in May. The leaves begin to become covered with brown or light red spots. Fungal spores actively reproduce on these spots. A sick bush dies very quickly.
Wrinkled leaves
The carrier of this infection is aphid, it transfers this disease from plant to plant, and at a cosmic speed. Therefore, the plant should be carefully examined not only for the presence of diseases, but also for the presence of pests. Disease with this virus leaves, become smaller, a yellow edging appears. Between the veins, the fabric becomes wrinkled. And the veins become crooked and not neat. In this case, the plant can only be saved by applying preventive plant treatments from fungi and pests.

White spot is treated very simply, we take two tablets of Alirin B and dilute everything in a liter of water, repeat the treatment 5 times per season, the interval between them should be at least a week.
Brown spot is removed using the drug Fitosporin M. We take 5 gr. preparation and diluted in 10 liters. water. We carry out processing every 5 days throughout the season.
Verticillary wilting can be defeated only with the help of the drug Maxim. One liter of water only needs 2 ml. funds, processing is carried out at the root, three times per season.
Late blight can be cured with several drugs such as: glyocladin, planriz, trichocin, trichodermin. The listed drugs must be diluted according to the instructions indicated on the package, the number of treatments, approximately 2 - 3 times in one season.
Powdery mildew should be treated with drugs such as:

Strawberries: diseases and treatment with folk remedies
Strawberries: diseases and treatment with folk remedies
If you do not want to resort to the help of poisonous preparations, then you can safely use folk remedies and methods of combating strawberry diseases. If the plants are affected by gray rot, then I use an infusion of mustard powder. For this we need 100 gr. mustard. Fill the mustard with 10 liters of boiling water and leave to infuse for 48 hours. Then we dilute the solution one to one and carry out the processing. But it is worth remembering this procedure should be carried out only on the appearance of buds. You can also plant onions or garlic around the strawberry garden to improve the effect.
At the initial stage of the disease of a strawberry bed with powdery mildew, an infusion of rotted hay is an ambulance.It is prepared as follows: pour one kilogram of hay with three liters of water and leave it to infuse for about 6 hours. After the infusion, you need to strain well and you can process the plants. Processing is best carried out in the evening, during the season you will need to carry out at least 5 treatments. Treatments are carried out every 7 days.
Wood ash is the best prevention against diseases that occur in the spring. For one square meter of the garden, you will need 70 grams. ash. But if this measure turned out to be ineffective and the diseases nevertheless attacked the strawberry garden, then you should use an infusion of garlic. We take half a kilo of garlic and chop it well, fill it with 10 liters of water and leave it for a day, brew. We filter the infusion and dilute one to one with water.
Starting in May, strawberries should be sprayed with iodine solution every week (only 10 drops are needed for 10 liters of water). This preventive measure will protect your plantings and help your plants develop immunity to viruses and infections.
