Every gardener dreams that strawberries on his site will delight you with tasty and healthy berries. But diseases and pests of garden strawberries can ruin the beauty of the harvest.


  • Diseases
  • Major pests
  • Nematode
  • Weevil


  • White spot

Brown spots form on the leaves, which grow and turn white in the center. As a result, the leaf becomes perforated. Brown spots on the petioles and whiskers.

The fight against spotting consists in thoroughly cleaning the garden and processing the plants until the leaves appear with nitrafen.

  • Brown spot

Brown spots form on the leaves. After a while, black pads with spores appear on the upper side of the sheet. You can get rid of brown spot in the same way.

  • Gray rot

Brown spots appear on the strawberries, and then a gray fluffy bloom. Contact with the ground increases the likelihood of infection.

In order to avoid the appearance of gray rot, it is necessary to prevent the appearance of weeds, use ash or lime. Before the leaves appear, strawberries should be treated with nitrafen, and before flowering - with the "Barrier" preparation. You can also plant strawberries among onions and garlic.

  • Powdery mildew

The leaves turn purple, a white bloom appears on them. All aboveground parts are affected.
To combat powdery mildew, you need to treat strawberries with topaz before flowering, as well as after harvesting.

  • Verticillary wilting

The base of the bush is affected, as a result the lower leaves wither, and then the rest. Prevention - soil disinfection with nitrafen.

  • Greening the petals

Light green spots appear on the leaves. Almost no berries are formed.
To combat greening, strawberries should be treated with karbofos and weeds should be destroyed before flowering, as well as after harvesting the fruits.

Major pests

It is best to use natural remedies to combat strawberry pests. After all, children rarely wash berries from the garden.


The most common and most harmful pest is the nematode. These are very small, threadlike worms, invisible to the naked eye. Inhabited by two types of strawberries: stem and strawberry. They feed on the juice and tissues of strawberries, destroying them. Plants deform and die over time. The harvest drops sharply.

Stem nematode infects leaves together with petioles and strawberry peduncles. The leaf blades are curved, the petioles are greatly shortened. Thickening may be visible on the petioles. The plant becomes, as it were, a dwarf form, and after about 3 years it dies. Mustaches should not be taken from infected plants for propagation, as they are infected.

The strawberry nematode is usually colonized in buds as well as flowers and berries. They are deformed. More often this is strongly manifested on the berries of the second and third collection. If the bushes are severely affected, then they are so deformed that they become like broccoli bushes. The leaf stalks are shortened, the leaves bend, the whiskers thicken, the flowers take on an ugly shape. Berries ripened on the affected bushes are completely tasteless and strongly curved.

The nematode spreads especially strongly during the wet period. The recommended treatment measure is the biological product Nemabact. It is also necessary to always plant marigolds in strawberry beds. Their phytoncides prevent nematodes from multiplying. Thus, you will prevent your plantings from spreading. Of course, the nematode will not go anywhere from an infected plant. But it certainly cannot spread because of the marigolds.


Another unpleasant guest on our plantations is the weevil. This is a beetle that hibernates right under the strawberry bushes. He goes out to "hunt" from the soil when it warms up to +8 degrees. By this period, the flower stalks just come out of the strawberries, the buds themselves stand out. It is in this isolated bud that the weevil beetles lay their eggs.

The very first buds of strawberries are usually the largest, and it is them that this bug damages. The buds droop and dry up. Can you imagine how offensive it is? Then the weevil goes to raspberries, so it is already pointless to fight on strawberries at this moment.

The weevil will return back by the time the strawberries have fresh shoots of growing leaves. Their bites can also be spotted by the pinpoint punctures that appear after they return. They are fed with fresh plant sap before wintering.

They hibernate, as already mentioned at the beginning of the section, right there, right under the strawberry bushes.

The periods of treatment depend on the described phases of insect development. The site is processed three times. The first time - at the stage of separation of buds on strawberries, then at the time of separation of buds on raspberries, and then during the appearance of punctures on young strawberry leaves. Use the herbal preparation Fitoverm, as well as weed infusions.

Diseases of garden strawberry should be taken seriously and not ignored. And to avoid problems with major pests, use our recommendations. Then this berry will thank you generously.
