The most common causes of strawberry drying
Owners of strawberry beds at times have to deal with the problem of drying the bushes that have begun to bear fruit for unknown reasons. In fact, these reasons are easy to find, and today you will find out what you need to do. In addition, we consider ways to effectively combat the drying of plants and prevent its occurrence.
The reasons why strawberries dry during fruiting
During fruiting, strawberries can dry for the following reasons:
- she lacks water;
- too much water;
- the bushes received a sunburn;
- the plant is planted in the wrong place;
- feeding has not been carried out;
- excess fertilizer;
- fungal infection;
- pest attack.
A sign of water shortage is cracked soil in the garden. Excessive watering may indicate wetlands. Strawberry leaves get a burn if water gets on them or the bushes are watered at a time when sunlight is in full swing. Planting bushes in a shaded, cool and windy place also makes strawberry growth difficult, which requires a lot of heat and sunlight.
Important! An excess of nutrients is no less harmful, since an excess of one of them complicates the assimilation of the rest, as a result, drying occurs, the plant withers.
Signs of strawberry nutrient deficiency include:
- drying out;
- dark green color, spots of purple, lilac, blue, black - if there is not enough phosphorus;
- light green, almost yellow color of leaves - if there is not enough nitrogen;
- coagulation of leaf edges, yellow or brown spots, wrinkling - if there is not enough potassium;
- dome-shaped leaves with curved down edges and multi-colored spots, although the veins retain a green color - if there is not enough magnesium;
- spots throughout the bush, turning the edges of the leaves up, dying areas on old leaves, young foliage develops poorly and gets thicker - if there is not enough zinc;
- the presence of white leaves - if there is not enough iron;
- clarification of veins on the leaves - with a lack of sulfur;
- spotting, which comes from the base of the leaf - if there is not enough manganese;
- torn, deformed leaves - with a lack of calcium;
- curvature of foliage and stem, discoloration of veins - with a lack of boron;
- withering of the top of the bush - with a lack of copper;
- the presence of points on the leaves, swollen areas, deformation of the edges - if there is not enough molybdenum.
Such diseases can lead to drying of strawberries:
- gray rot;
- powdery mildew;
- late blight.
Did you know? Gray rot cannot be dispensed with when creating dessert wines of the elite class Tokai and Sauternes.
One of the most common diseases is gray rot, which usually affects densely planted strawberries during periods of high humidity. It can be identified by the presence of brown spots, rotten places, gray shaggy coating on berries and gray coating on foliage. The presence of these signs should prompt you to completely remove the diseased bush, burn it, water the place of its growth with Bordeaux liquid, copper sulfate or a slightly pink solution of potassium permanganate.
The defeat of the fungus, leading to the appearance of powdery mildew, can be detected by the following signs:
- the underside of the leaves becomes powdered white dust with droplets of water;
- drying of leaves, antennae and ovaries;
- white dust on the berries rots them.
It develops in a moist, warm environment. You can fight with the help of such measures:
- remove fallen leaves in autumn;
- cut old foliage in spring;
- before the appearance of flowers and after harvesting berries 1-2 times a week, you can use soda ash diluted in water (50 g per 10 l);
- the rest of the time, a solution of whey in water in a ratio of 1 to 3 is used with the same frequency;
- spraying with the addition of 1 mg of iodine per 10 liters of water;
- daily infusion of 1 kg of ash in 10 liters of water;
- spraying with soapy water - grated household soap on a grater pour 10 liters of water, add 20 g of copper sulfate.
A strawberry develops a white spot if on the leaves along the edges and the central vein light points with dark edges that brighten are noticeable, their midpoints dry out, form holes, which then merge.
A brown spot is struck by the plant, if brown spots are visible along the edges of the leaves, and lilac spots on peduncles and mustaches. They darken and merge, black swellings with spores are noticeable on the leaves.
Signs of black spotting (anthracosis) are:
- spots of brick color on the leaves, along which cracks and tears pass;
- ulcers of a dark color with a bright middle on the stems;
- dark hollows on the berries.
To solve the problem it is necessary:
- remove affected plants;
- spray the remaining bushes with fungicides and preparations containing copper;
- in case of black spotting, treat healthy plants with Ridomil Gold, Metaxil, Quadris; in advanced cases, 1% Bordeaux fluid is required;
- reduce watering;
- Do not make fertilizers containing nitrogen;
- after picking berries, add phosphorus and potassium, spray with “Fitosporin”.
Signs of late blight are:
- dark color spots on the ovaries;
- dark purple spots on the berries;
- brown spots on the leaves;
- bitter taste, hard berries;
- drying of leaves, stems, berries.
Important! Chemical control agents are not used if less than 2 weeks are left before harvesting.
“Phytosporin”, copper sulfate, Bordeaux liquid, if the berries have not yet set, are suitable for treatment. The rest of the time, you can use soap, ash solutions, whey.
Harmful insects can suck out nutrients from strawberries and cause them to dry out. Next, consider the most common of them.
Straw mite, or transparent
Almost transparent insects up to 0.2 mm in size, which cannot be seen without special magnifying devices, are strawberry mites. Sucking the juice, they weaken the plant, which inhibits its growth. Their appearance can be suspected by oily plaque and wrinkled, twisted leaves, which acquire the color of wax. For the fight using 0.3% "Karbofos" or 0.2% "Keltan", which are used before the formation of ovaries or after picking berries.
Raspberry-strawberry weevil is a beetle up to 3 mm in size with a long proboscis, painted in black or gray. The beetle itself eats the first pedicels, and its larvae - buds. After degeneration into beetles, young leaves serve as food for them. They do not freeze in the winter and can continue wrecking for the next year. For the fight use "Nurell-D", "Karate", "Actellic", "Zolon", "Karbofos".
In order not to expose the crop to the risk of exposure to chemistry, you can use folk remedies:
- a solution of 2 tablespoons of soda in 1 liter of water;
- a solution of 3-4 tar caps in 10 l of water with the addition of a small amount of laundry soap;
- 3-day tincture of 1 kg of ash in 10 liters of water with the addition of laundry soap.
Slugs are clams of a dark color of an oblong shape, without shell. In the evening they crawl to the surface and eat berries and leaf edges. In the fight against them use the drug "Slimax" at a dosage of 5-7 kg per 1 ha of sowing or metaldehyde at a dosage of 8-10 kg per 1 ha of sowing.
Before planting seedlings, the soil is disinfected with formaldehyde. If there are berries on the bushes, you can prepare a solution of 10 tablespoons of mustard in 10 liters of water or a solution of 10 ml of green stuff in the same amount of water. Protection is also mulch.
Strawberry nematode is a cylindrical transparent worm 1 mm in size. He eats ovaries, buds, flowers, buds, they grow twisted, there are either no berries at all, or they are also irregular in shape. The affected bushes need to be torn out, the rest should be treated with iron sulfate at a concentration of 5%, copper sulfate at a concentration of 3% or tincture of 200 g of garlic in 1 liter of water. Before planting, lime is poured into the wells, and the plants are lowered alternately in warm and cold water.
A large beetle about 6 cm in size, painted brown, is called a bear. These insects gnaw the roots of strawberries, the plant begins to dry. Known methods of dealing with them:
- preparations "Marshall", "Hinofur", "Zolon," Force ";
- noise emitting devices - from cans, nuts, and other metal objects;
- solution of laundry soap;
- traps from high tanks buried 15 cm deep, filled with water or vegetable oil.
Methods of dealing with the problem
To eliminate the problem of drying strawberries use:
- proper watering;
- proper fit.
Mulching with straw or humus
You can adjust the soil moisture using mulch, which is dry (using straw or peat) and wet (using humus). This layer absorbs excess moisture, protects the soil from moisture evaporation, prevents fungi, slugs from multiplying, and protects berries from contact with the soil. After the snow has melted, it is necessary to cover a fresh layer of mulch in order to remove with it possibly overwintered larvae or mushroom spores.
Watering when there is no scorching sun
Plants are watered only at the root, so that moisture does not linger on the leaves, does not heat up in the sun, and does not burn them. For watering, morning or evening time is recommended, which will also help to avoid burns.
Chess arrangement of bushes
In order for each plant to receive a sufficient amount of fresh air, between them should be at least 25 cm, and between the rows - 30 cm. Planting in a checkerboard pattern will save space. Dense plantings need to be thinned out.
To prevent drying, the following actions are recommended:
- remove weeds;
- trim the mustache;
- disinfect the soil with potassium permanganate, vitriol, soapy water, ash or lime;
- cut foliage after harvesting;
- plant nearby onions and garlic;
- every 3 years to transfer the culture to another place;
- mulch the plant;
- plant disease-resistant varieties;
- thin out;
- Prevent waterlogging of the soil;
- water according to the rules;
- comply with fertilizer application technology;
- choose the right place for landing;
- treat with fungicides "Barrier", "Topaz";
- do not plant on the site after potatoes, corn, tomatoes, eggplant, cucumbers, peppers;
- spread fresh mulch in the spring;
- before flowering, after harvesting berries, before wintering, spray with a 1% solution of Bordeaux liquid;
- observe the distance between different varieties of strawberries;
- observe a distance of 0.3 m between the rows and 0.25 m between the bushes;
- plant healthy seedlings;
- fertilize properly;
- spray bushes with ash solution.
