Processing strawberries in spring from diseases And pests allows you to keep plants healthy and get a good harvest. To protect strawberries, you can choose special preparations and traditional methods. Treatment is carried out by spraying or watering the plants.
Processing rules
Strawberries are treated for diseases and pests after the snow melts. First you need to remove last year's leaves and other organic debris. Then the top layer of soil, where many pests overwinter, is removed.
Strawberry beds must be dug up. Too dense plantings are eliminated, as they attract insects and create conditions for the appearance of fungus.
The following recommendations for caring for strawberries will help reduce the likelihood of the spread of diseases and pests:
- Before planting, the soil and soil are cultivated;
- buy seedlings from trusted suppliers;
- every 3-4 years a new site is selected for planting;
- need to be weeded regularly weeds;
- Lupine or other plants that repel insects are planted next to strawberries.
Special solutions are used to process strawberries. They are used for watering or spraying plants.Work of any kind is carried out in the morning or evening. It is not allowed to perform procedures in direct sunlight.
Treatment for diseases
The cause of most strawberry lesions is a fungus. Lesions cover the root system, leaves, stems and berries of plants.
Timely pruning of strawberries will help avoid symptoms of disease. Spring processing of strawberries from diseases is carried out before flowering begins.
Powdery mildew
The above-ground part of strawberries suffers from powdery mildew. The lesion spreads in conditions of high humidity and heat.
Powdery mildew appears as a white coating that appears on the lower leaves of plants. Affected leaves curl and turn brown. The disease prevents pollination of strawberry flowers.
To avoid the spread of powdery mildew, you need to use healthy seedlings, regularly care for the plantings and not allow the strawberries to grow.
Strawberries can be treated with Quadris in the spring. Its active substance, when it comes into contact with the affected areas, blocks the flow of oxygen. As a result, harmful spores die. Treatment is carried out by spraying the plantings.
White and brown spotting
Spot affects strawberries during the growing season. As a result, the ovaries and fruits die, and the green mass is lost.
The disease can be identified by the following signs:
- the appearance of light or brown spots located along the edges of the sheet;
- As the disease progresses, the petioles die.
Removing dry strawberry stems and leaves and removing affected bushes will help to avoid the development of spotting.Nitrogen fertilizers are applied in limited quantities in the spring to avoid the growth of green mass and the spread of dampness.
An effective remedy for spotting is a solution of potassium permanganate. 5 g of this substance is diluted in 10 liters of water, then used for leaf treatment.
For spotting treatment use fungicides aimed at eliminating disease spores. In case of mass destruction, preparations containing copper (Bordeaux mixture, oxychloride) are used.
Gray rot
The causative agent of gray rot appears when there are plant residues in the soil. Its spread is facilitated by cold weather and high humidity. At first, the disease manifests itself in the form of spots and white plaque, which quickly grow.
10 liters of water require 10 ml of iodine. Plantings must be treated every 10 days.
When the first symptoms of gray rot appear, an infusion of garlic is prepared (1 kg of dried leaves per bucket of water is enough). Mustard infusion is also effective (50 g of powder is needed per bucket of water).
How to process strawberries from gray rot, you can choose from a wide range of products. In spring it is allowed to use chemicals. The drugs “Euparen multi” and “Fundazol” are used against gray rot.
To prevent gray rot, 2 tablets of the drug “Alirin-B” are dissolved in 1 liter of water, after which the plantings are treated before flowering begins. After 10 days, the procedure can be repeated.
Root rot
Diseases of the root system are observed in young plants. The lesion appears in the form of small black spots that gradually cover the entire root system. Subsequently, the strawberry bushes turn brown.
Root rot cannot be treated. The strawberries are dug up and then burned to prevent the spread of the disease.
Therefore, in the spring, increased attention is paid to preventive measures. Only rotted compost is used to fertilize the plantings. Additionally, after the snow cover has melted, you can treat the beds with Trichodermin.
Pest treatment
Insects cause irreparable damage to strawberry plantings. To preserve the plantings, special preparations are used. For prevention, you can use folk remedies that have disinfectant properties. The main strawberry pests and their control are given below.
Strawberry mite
For berry growers, one of the most dangerous pests is the strawberry mite. These insects prefer young plantings and the lower parts of bushes. The mite is a carrier of fungal diseases of strawberries, so increased attention is paid to the fight against it.
The presence of strawberry mites can be identified by the following signs:
- strawberries develop slowly;
- plant leaves are curled and torn at the edges;
- the berries dry out before ripening;
- freezing of strawberries.
Most of these symptoms are noticeable during the fruiting period of the plants. in spring from pests and diseases It is necessary to carry out preventive measures aimed at disinfecting soil and plants.
The following methods will help you get rid of strawberry mites:
- pour a decoction based on tomato tops or dandelion infusion;
- we treat with special preparations (Karbofos and others).
Plantings can be treated with onion peel infusion. This requires 0.2 kg of husk and a bucket of water. The product is infused for 5 days, then it needs to be strained and poured over the strawberries.
Spider mite
Spider mites choose dry areas that are well lit by the sun. Its active period begins in early spring. The presence of this insect can be detected by the cobwebs that remain on the strawberry leaves.
You can fight spider mites using the following methods:
- infusion based on wormwood or tobacco;
- treatment with Karbofos.
Plants need to be sprayed in the spring when leaves are growing. The procedure is performed twice with a break of 10 days.
Weevil
The weevil causes irreparable damage to strawberry plantings because it prefers leaves and peduncles. It is identified by wilted flowers. Early varieties of strawberries especially suffer from weevil attacks.
An infusion of wormwood will help prevent the appearance of weevils. First, 1 kg of plants are crushed, filled with water and brought to a boil. After 10 minutes, filter the broth and add a little soap (up to 40 g). The resulting product is diluted in 10 liters of water.
Based on wood ash, an effective solution for controlling strawberry pests is obtained. For 10 liters of water, 3 kg of wood ash is required. The infusion must be kept for 24 hours and then used for spraying.
Another remedy for weevils is tansy infusion. 1 kg of this plant is poured into 5 liters of water and left for a day. The resulting infusion must be boiled for 30 minutes, filtered and soap added. Add 10 liters of water to the solution and obtain a ready-made product for sheet treatment.
Slugs
Slugs can destroy strawberry plantings, so timely measures must be taken to combat them. To do this, the area with the strawberries needs to be fenced off with a small ditch, into which lime, ground pepper or wood ash is poured.
Superphosphate, which is poured between the rows of plantings, will help get rid of slugs. Treatment for pests is carried out in the evening, since they are most active at night.
Whitefly
The whitefly is a small insect that resembles a butterfly. It lives in the shade and does not tolerate direct exposure to the sun.
Strawberries are treated against pests using special preparations - “Nurell D”, “Aktara”, etc. The procedure is carried out before the strawberries begin to bloom. Small affected areas are sprayed with garlic infusion.
Conclusion
Chemicals and traditional methods are used to treat strawberries against pests and diseases. To maintain plants in good condition, you need to follow the rules for planting them, trim them in a timely manner, provide dry leaves and apply fertilizers.
