How to protect strawberry leaves from diseases, who can eat them and what to do about it?

Strawberries or garden strawberries are a berry that is most popular among a huge number of summer residents and amateur gardeners. Over the past decades, unique varieties have emerged that have outstanding taste qualities.

Leaf diseases and their treatment

These types of strawberries have:

  • Frost resistance.
  • Good resistance to pests.
  • Excellent yield.

It is very important to be able to protect the harvest of berries from pests, of which there are a great many.

You should know:

  • Symptoms of strawberry damage.
  • What protective measures should be taken.
  • What is the prevention.

Ailments can be expressed in a variety of forms. Often there are the same signs that can characterize various diseases from metabolic disorders and lack of moisture, to damage by weevil or aphids. The first and most important sign is a change in the color of the leaves and the shape of the fruit.

If the berries are small, they dry out on a branch - this primarily indicates a lack of water. Strawberry is a heat-loving plant that loves an abundance of sunlight and moisture, if any of these components is missing, it becomes noticeable after a short time. In such situations, it is recommended to revise the watering schedule, make it more private.

If there are no berries on the bushes, then this indicates that the plantations belong to the category of "weeds".No ovaries appear on such plants, only barren flowers are present. Often in a particular region of Russia a cold spring is issued, plants can be damaged by exposure to negative temperatures.

It also happens that with the command of the ovaries, their drying begins almost immediately. The reason for this may be the formidable enemy of strawberries - the weevil. An extremely dangerous insect (beetle) that can destroy crops by 98%.

The female beetle lays eggs in buds, the incubation period passes, after the appearance of offspring, the bud will be eaten by the “younger generation”. A similar phenomenon occurs in the first half of summer. The weevil feeds on leaves and roots with pleasure. Around the world there is a colossal number of the family of this insect - 50 thousand species.

It is necessary to take preventive measures so that the situation does not get out of control.

The leaves quickly turn yellow, darken and wither. Perhaps the plants receive too much ultraviolet radiation, the sun's rays "burn" the foliage.

If there is not enough magnesium in the soil, the foliage becomes covered with granular specks of a yellowish-gray color.

If there is not enough iron, then a yellow color is also formed between the veins. The yellowness of the leaves can be triggered by the vital activity of harmful insects, for example, such as:

  • Tick.
  • Aphids.
  • Weevil.

If strawberry leaves turn red, then turn brown, then this indicates a potassium deficiency.

Often the leaves in July are covered with a red bloom, the edges are curled, it becomes wrinkled. Reason: bushes planted too close to each other.

If the edges of the leaves become rusty, drying up, wrapped up, then they were struck by pests:

  • Phytovtorosis.
  • White-winged butterfly.
  • Strawberry leaf beetle.

If the plantation was attacked by a tick, then many leaves become hard, rough, curl up into tubules and turn black.

If the fruits have the wrong configuration, this is due to a boron deficiency.

Cold weather is also a serious factor, the plant receptacle can be damaged by negative temperatures.

Most often, strawberries are affected by a fungus, in second place in terms of distribution is mosaic spotting and witch's broom. Nothing can be done with such misfortunes as “broom” or “spotting”, the plant must be promptly disposed of so that no further infection occurs.

White rot is also a very common disease. Light green “blots” of various sizes appear on the leaves, gradually they begin to decompose. Sometimes leaves and berries are covered with a white pale cover, similar to talcum powder.

White rot does not occur in greenhouses, in the fresh air, if you cover the culture with a film, that is, there is a hope that the infection will not "hook" the crop.

Gray rot covers shrubs with a grayish coating of rust. Such a “powder”, there is a huge amount, even small clouds are formed that scatter over the site. The disease can spread at the speed of a forest fire, if nothing is done, then the crop will be destroyed by 99%.

Strawberry varieties that ripen early and are not afraid of grayish rot:

  • "Ruby pendant".
  • "New" and many others.

Fungus white spotting (ramulariasis) appears at the end of the warm season. All foliage is covered with reddish spots, wrinkling appears on the leaves, the spots increase in size, turn white, the border of the leaves begins to dry out. In the end, the leaves dry up, the fruits are also affected.They should not be eaten.

Pests and getting rid of them

Anthracnose is a dangerous fungus that eats plants weakened by nutrient deficiencies. Spores are transmitted through insects or wind. Strawberry varieties such as:

  • "Pelican" and "Idea".
  • "Pegan" and "Daver".

The berries and leaves are "painted" with gray-brown stains, then in place of individual spots on the berries, small sores appear, which increase in size. The whole bush eventually dries up and dies. Depressed spots on the berries are the signature "handwriting" of anthracosis, which can be destroyed by means of:

  • "Fitosporin".
  • "Topsin-M".
  • "Gamair".

Potassium humate should also be added to the chemicals. Anthracosis treatment is done at least three times per season. The drugs are also very good:

  • "Acrobat".
  • "Speed".
  • Fundazol.

The strawberry nematode is a formidable enemy, the appearance of which can be provoked by diseased seedlings. Before planting plants, they should be rinsed well under high pressure of water (do a Charcot shower), this eliminates the larvae. Before planting, a teaspoon of lime is placed at the bottom of the hole.

If a nematode appeared on the plantation, then the crop of the plant should be uprooted and burned.

Identifying nematodes is easy:

  • Plants become brittle.
  • Knots on the trunks increase.
  • The bloom is gone.
  • Berries become a strange configuration.
  • Small white worms (no more than a millimeter in size) are visible in the roots of the plant.

To eliminate the nematode, the site should be sprayed three times a season with tinctures that are made from dandelions and tomato tops.

The caterpillar of the leaf-rolling butterfly, only 7–9 mm in size, weaves a web and wraps the leaves and berries in a cocoon.The parasite eats leaves, if further reproduction of these insects is allowed, then the number of leaves will noticeably decrease. Plants should be treated with infusion of various herbs, as well as ash. From chemistry use:

  • "Altar".
  • "Inta-CM".

Spraying should be done during the formation of buds, as well as after harvesting.

Preventive measures

Factors that actively contribute to the spread of infection in the beds:

  • Lack of lighting.
  • Landing neglect.
  • High percentage of humidity.
  • Oversaturation with nitrogen.

The most common parasite on strawberry plantations is the strawberry mite.

It has microscopic dimensions, it is not easy to see it. The result of the “work” of the pest is wrinkled, mutilated leaves, on which greasy spots appear.

The tick is fertile (up to 6 generations per season), if there are fifty individuals on the site, then in September the number of the colony will exceed one million individuals. If the summer is cold and rainy, then a real holiday begins for the tick. Before planting, seedlings should be washed with hot water (+47 degrees), then washed with cold water (+8 degrees).

After fruiting has passed, on a sunny hot day, the beds are covered with a black film, a thermometer is placed under it. Upon reaching a temperature of +58 degrees, the film is removed. The leaves are then cut and burned. In spring, the beds are treated with hot water (not lower than +62 degrees).

A universal remedy is an infusion of onion peel. 220 grams is enough for a bucket of water. The culture is periodically watered with infusion (at least four times per season).

A very dangerous disease, which is called gray rot, it spreads very quickly. As a preventive measure, bushes should be treated with infusions based on onions or garlic. The following compositions are actively used:

  • "HOM".
  • "Tiram".
  • "Figon".

They begin to process plants as soon as the buds are swollen. We should not forget about mulching, the berries should not touch the ground.

The culture should be thinned out more often, removing spoiled fruits. Watering is not always urgently needed. The soil also sometimes needs to rest from moisture. It is sometimes useful to treat the earth with potassium permanganate, add ash.

It is necessary to feed from such a mixture: only 2.1 grams of boric acid and only 25 drops of iodine are added to a bucket of water

If the leaves dry, most likely, a fungal disease, such as late blight, can be the culprit. It is also possible that the whitefly and the strawberry leaf beetle started up on the site. The following compositions are very effective in combating rot:

  • "Derosal".
  • "Horuss".
  • "Ballet".

Each package contains instructions on how to dilute a particular chemical. You need to read them carefully. It is strictly forbidden to use chemical compounds for half a month before fruiting.

Often, experienced gardeners plant onions, garlic, the smells of these crops repel pests. Every decade, plants are treated with bushes with a solution of mustard or a mixture made on the basis of pepper (red). The soil is sprinkled with wood ash.

All of the listed substances are quite effective, they should only be used within reasonable limits, not overdoing it with concentration.

Aktelik is also often used - it is an effective drug for the elimination of weevils. For two liters of water, 2.5 ml of the composition is enough; this solution is enough for ten square meters of crops. You should re-spray "Aktelik" after seven days. It is strongly not recommended to use Bordeaux liquid and Aktelik at the same time.

Folk remedies in the fight against weevil are also very effective. To get rid of this annoying pest, make a solution of laundry soap and mustard, add a little ash. The mixture is insisted for two days and sprayed with strawberries using a spray bottle. If misfortune happened, the weevil firmly settled on strawberries, then it is sprayed:

  • "Intavir".
  • "Gordon".
  • "Metophos".

It is best to process the buds themselves, where insect larvae live.

      The weevil does not know how to fly, in the morning it is sluggish and clumsy, plants affected by this pest should be uprooted and burned. It should be remembered that after treatment with insecticides, bees do not sit on such plants, preventive measures should be applied reasonably, at the right time, so as not to be left without a crop.

      Ants can bring a great disaster for culture, they are very fond of feasting on berries. Often, toxic special baits are used against them.

      Moles also cause their harm to plants. They can destroy the root system of plants in any area. To effectively deal with them, toxic baits and ultrasonic installations are used.

      Slugs can cause crop failure. Berries that are close to the ground are eaten by these creatures. The beds should be weeded regularly. To collect these "beauties", not letting them eat valuable berries.
