Processing strawberries in the spring from diseases and pests allows you to keep the plants healthy and get a good harvest. To protect strawberries, you can choose special preparations and folk methods. Processing is carried out by spraying or watering 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 they remove the top layer of the earth, where many pests overwinter.
Beds with strawberries must be dug up. Too dense plantings are eliminated, as they attract insects and create conditions for the appearance of the fungus.
The following recommendations for caring for strawberries will help reduce the likelihood of the spread of diseases and pests:
- before planting, soil and soil are cultivated;
- buy seedlings from trusted suppliers;
- every 3-4 years a new site is selected for planting;
- weeds need to be weeded regularly;
- lupins or other plants that repel insects are planted next to strawberries.
For the processing of strawberries, special solutions are used. They are used for watering or spraying plants. Work of any kind is carried out in the morning or in the evening. It is not allowed to perform procedures in direct sunlight.
Disease treatment
The cause of most strawberry lesions is a fungus. The lesions cover the root system, leaves, stems and berries of plants.
Timely pruning of strawberries will help to avoid symptoms of diseases. Spring processing of strawberries from diseases is carried out before flowering.
Mučnistaâ rosa
The ground part of the strawberry suffers from powdery mildew. The lesion spreads in conditions of high humidity and heat.
Powdery mildew has the appearance of 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 plantings and do not allow strawberries to grow.
Strawberries in spring can be treated with Quadris. Its active substance, when it enters the affected areas, blocks the flow of oxygen. As a result, harmful spores die. Processing is carried out by spraying plantings.
White and brown spots
Spotting affects strawberries during the growing season. As a result, the ovaries and fruits die, the green mass is lost.
You can identify the disease by the following signs:
- the appearance of light or brown spots located along the edges of the sheet;
- with the development of the disease, the petioles die off.
The removal of dry stems and leaves of strawberries, the removal of affected bushes will help to avoid the development of spotting. Nitrogen fertilizers are applied in the spring in limited quantities 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 sheet processing.
For the treatment of spotting, fungicides are used to eliminate spores of the disease. In case of mass damage, preparations containing copper (Bordeaux liquid, oxychloride) are used.
Gray mold
The causative agent of gray rot appears in the presence of plant residues in the soil. Its spread is facilitated by cooling and high humidity. At first, the disease manifests itself in the form of spots and white plaque, which grow rapidly.
10 ml of iodine is required for 10 liters of water. It is necessary to process landings every 10 days.
When the first symptoms of gray rot appear, an infusion of garlic is prepared (1 kg of dried leaves is enough for a bucket of water). Mustard infusion is also effective (50 g of powder is needed for a bucket of water).
How to process strawberries from gray rot, you can choose from a wide range of products. In the spring it is allowed to use chemicals. Against gray rot, the preparations “Euparen multi” and “Fundazol” are used.
For the prevention of gray rot, 2 tablets of 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
Root system diseases are observed in young plants. The lesion manifests itself in the form of small black spots, which gradually cover the entire root system. In the future, strawberry bushes become brown.
Root rot is not treatable. 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. For fertilizing plantings, only rotted compost is used. Additionally, after the snow cover has melted, the beds can be treated with the Trichodermin preparation.
Pest control
Insects cause irreparable damage to strawberry plantings. To save the planting, special preparations are used. For prevention, you can use folk remedies that have disinfectant properties. The main strawberry pests and their control are listed below.
Strawberry mite
For the berry plant, one of the most dangerous pests is the strawberry mite. These insects prefer young plantings and the lower parts of bushes. The tick is a carrier of fungal diseases of strawberries, therefore, increased attention is paid to the fight against it.
The presence of a strawberry mite can be identified by the following signs:
- strawberries develop slowly;
- plant leaves are twisted and torn at the edges;
- berries dry up before ripening;
- freezing strawberries.
Most of these symptoms are noticeable during the fruiting period of the plants. In the spring, from pests and diseases, it is necessary to carry out preventive measures aimed at disinfecting the soil and plants.
The following methods will help get rid of strawberry mites:
- water with a decoction based on tomato leaves or infusion of dandelions;
- we process with special preparations (Karbofos and others).
Plantings can be treated with infusion on onion peel. This requires 0,2 kg of husk and a bucket of water. The product is infused for 5 days, then it must be filtered and watered with strawberries.
spider mite
The spider mite chooses dry areas that are well lit by the sun. The period of its activity begins in early spring. The presence of this insect can be detected by the web that remains on the strawberry leaves.
You can fight spider mites in the following ways:
- infusion based on wormwood or tobacco;
- processing “Karbofosom”.
Spray the plants in the spring during leaf growth. The procedure is performed twice with a break of 10 days.
Weevil
The weevil causes irreparable harm to strawberry plantings, as it prefers leaves and peduncles. It is identified by wilted flowers. Early varieties of strawberries are especially affected by the attack of the weevil.
An infusion of wormwood will help to avoid the appearance of weevil. Previously, 1 kg of plants is crushed, poured with water and brought to a boil. After 10 minutes, the broth is filtered and a little soap is added (up to 40 g). The resulting product is diluted in 10 liters of water.
Based on wood ash, an effective solution is obtained for pest control of strawberries. For 10 liters of water, 3 kg of wood ash is required. The infusion must be kept for a day, and then used for spraying.
Another remedy for weevil is an infusion of tansy. 1 kg of this plant is poured into 5 liters of water and left for a day. The resulting infusion should be boiled for 30 minutes, filtered and soap added. 10 liters of water are added to the solution and a ready-made sheet processing agent is obtained.
Slugs
Slugs can destroy strawberry plantings, so you need to take timely action to combat them. To do this, the area with strawberries needs to be fenced with a small ditch, where lime, ground pepper or wood ash is poured.
Superphosphate, which is poured between the rows of plantings, will help get rid of slugs. Pest control is carried out in the evening, as they are most active at night.
whitefly
The whitefly is a small insect resembling a butterfly. It lives in the shade and does not tolerate direct exposure to the sun.
Strawberries are treated against pests with the help of special preparations – Nurell D, Aktara, etc. The procedure is carried out before the strawberries begin to bloom. Small affected areas are sprayed with infusion of garlic.
Conclusion
Chemicals and folk methods are used to treat strawberries from pests and diseases. To maintain plants in good condition, you need to follow the rules for planting them, cut them off in a timely manner, give dry leaves and apply fertilizer.
