STRAWBERRY DISEASES
Powdery mildew on strawberries (photo 1)
You can understand that she attacked your plants when the surface of the leaves is covered with a white powdery bloom. The leaves stop growing and bend upward. Affected berries stop developing and rot. The plantation looks depressed.
You can fight strawberry powdery mildew by collecting and burning affected leaves and berries.
Treatment with a suspension of colloidal sulfur (80-90 g per 10 l of water) during budding and after harvesting helps. You can use a solution of soda ash (40 g per 10 L of water), it is useful to add to the solution of laundry soap (20-30 g).
Gray rot of strawberries (photo 2)
From this disease, ripe berries rot, becoming covered with gray mold.
You can overcome the gray rot of strawberries by collecting and destroying the affected berries.
Treatment of strawberries before flowering with copper oxychloride (12 g per 10 liters of water) also helps. Can be treated with 1% Bordeaux liquid.
Strawberry black rot
The collected fruits rot, and a white mold-invisible mass is formed on them, which turns gray over time.
You can get rid of the misfortune by processing the plantings of strawberries before flowering with copper oxychloride (10 g per 10 l of water). Repeatedly - after picking berries.
Various spots on strawberries (photo 3)
Plants turn brown, dry out, and affected leaves fall off, which causes a decrease in yield.
You can get rid of strawberry spots by collecting and destroying the affected leaves. In case of severe damage, carry out three times treatment with 1% Bordeaux liquid or copper oxychloride (25-30 g per 10 L of water). Carry out the first treatment at the time of exposure of the buds, the second - after a week and the third - after harvesting.

STRAWBERRY PESTS
Strawberry weevil on strawberries (photo 5)
These are beetles that feed on young leaves, eating at them
holes. They gnaw off peduncles, laying eggs in them. One individual destroys up to 50 buds.
You can fight the strawberry weevil by collecting and burning plant debris. And also by processing plantings with a solution of wormwood at the beginning of budding.
Strawberry mite on strawberries (photo 4)
Its larvae damage leaves by sucking juices out of them. Leaves wrinkle, turn yellow prematurely, sometimes dry up and fall off. Bushes reduce growth activity, yield drops.
Thermal disinfection of seedlings before planting in the ground (placing in water with a temperature of 45 ° for 10-15 minutes) will help to cope with the strawberry mite. A double spring treatment of plants with a decoction of tomato tops has a positive effect. The green mass must be prepared in autumn by collecting and drying. The norm is 1 kg of tomato mass per 10 liters of water. Dandelion infusion can also be used against the tick.

The harm from it lies in the fact that the affected plants lag behind in development, the leaves and petioles on them turn red. The leaf blades become wrinkled and become very shallow. In the future, the leaf petioles swell a little. The yield is greatly reduced.
To control the strawberry nematode, the infected plants should be removed and burned. The soil where the infected plants grew must be treated with bleach. Other control measures are ineffective.
Wireworm on strawberries
Its larvae gnaw holes in the roots and aboveground parts of strawberry plants. Plants look depressed, they lose part of the harvest.
You can fight the wireworm using traps - pieces of potatoes placed in a rag tied to a stick. After a couple of days, remove the stick from the soil, destroying the pests that have accumulated in the parts of the potatoes.
Slugs (photo 7)
They damage strawberries in humid, shaded areas. Berries lose their presentation, rot.
It will help to defeat slugs by collecting and destroying pests under any shelters: boards, iron sheets, fallen trunks and shoots, as well as dusting the row spacing with copper sulfate or superphosphate, dusting the soil with quicklime - in the morning and in the evening, especially after rain.

Dobrý den, děkuji předem za radu. Mám pár sazenic měsíčních jahod. Nějakým způsobem se mi tam rozmnožily jahody jednoplodící. Krasně vyrostly, kvetly, ale neutvořily se jahody. Zakrsly. vedle jsou měsíční, které rodi. Nevim důvod. Maji málo zhivin? Spatnou půdu? Chtěla bych je přesadit, ale nevím jestli budou příští rok rodit. Vyhazuji omladky. Mám jahodník, který chystám obnovit, porýt, novou hlínu, nové sazenice. Děkuji za odpověď. Galova Svatava

Small bugs appeared on the strawberry bushes. They eat leaves, flowers. How to get rid of pests?
#
- Your plants, most likely, are harmed by the beetles of the raspberry-strawberry weevil. You can deal with them in different ways. Mechanical measures
Collect beetles by hand and destroy them immediately. The same applies to fallen buds.
Use traps: in a container with a narrow neck, pour a mixture of 500 ml of water, 50 g of yeast and 100 g of sugar.
Chemicals
Insecticides (Fufanon, Inta-Vir) can be applied 7-10 days before the flowering of strawberries, when the first buds begin to appear. Repeat the treatment after fruiting. Biological preparations
We are talking about the drugs Nemabakt, Fitoverm, Akarin - these are biological protection means containing a nematode that destroys insects. Introduce into the soil also during bud extension and after harvest. Folk remedies
Plant onion and garlic plants around the strawberry patch.
When beetles appear, you can sprinkle the aisles with wood ash or sprinkle the plants abundantly with garlic infusion (infuse 100 g of garlic gruel in 10 liters of water for a week) or infusion of ground hot pepper (300 g per 10 liters of water).

Young leaves of strawberry (garden strawberry) curl and do not unfold. Why?
#
- This is the work of the strawberry mite. A dangerous pest damages the harvest not only of the current, but also of the next year, since it disrupts the formation of flower buds at the end of summer.
Control measures
During the extension of the peduncles, spray the bushes (and the underside of the leaves!) With Aktelli-com, Omayt or Fufanon (according to the instructions). Repeat treatments 1-2 times with an interval of 7-10 days.
A tick most often comes to a new plantation with planting material. Therefore, before planting, completely immerse the seedlings in hot water (+ 13 ... + 15 degrees) for 45-46 minutes.
In case of abundant colonization of fruit-bearing plantations with mites, immediately after harvesting, mow the leaves and spray with an insecticide or in hot weather cover the ridge with plastic wrap (at a temperature of + 45 ... + 50 degrees, the pests die).
