One of the worst enemies of gardeners are parasitic worms - nematodes. It is a rounded worm about 1 mm long. It attaches to the plant stem, injects a special substance that causes a chemical reaction, as a result of which plant tissues become an ideal food for the parasite.

How to detect a pest
Due to its microscopic size, it is not possible to detect the nematode with the naked eye. But if you suspect the presence of parasites, dig up the plant and carefully examine the root system. The affected roots will be littered with white cysts resembling poppy seeds.
What is the danger
Strawberry Nematode It is dangerous primarily because it is almost impossible to notice at the initial stage of reproduction. Thus, it gradually harms the soil and plants, worsening the yield, or even leads to its complete absence. With a strong lesion in plants is observed:
- wrinkles and leaf curl;
- slow growth of leaves and stems, due to the defeat of the root system;
- yellowing leaves;
- poor flowering or lack thereof;
- violation of the natural shape of the berries.
- anorexia, nausea, vomiting;
- allergic skin reactions;
- muscle pain;
- general weakness due to intoxication;
- possible mental disorders, depression.
Is it possible to secure strawberries
The fight against the nematode on strawberries is carried out by various methods, but all have a common feature - this is a protracted process.
Traditional ways of dealing:
- Planted next to the strawberry plants that repel nematodes: marigolds, marigolds, nasturtium, calendula.
- Change the place of planting strawberries every 4-5 years.
- Near the plantation, shallow trenches are dug out and covered with lime, which has a destructive effect on nematodes.
- Destruction of infected bushes.
- Fertilizer soil manure. It creates a favorable environment for the development of protozoan fungi, which are also destructive for parasites.
- Heat treatment of an infected shrub. The plant must be dug, washed the roots and immersed in water at a temperature of about 50 ºС. Stand 5 to 20 minutes.
- "Lindane";
- "Phosphamtide";
- Mercapthos;
- "Heterofos".
Prevention: how to protect and disinfect seedlings
As a preventive measure from the stem nematode, it is advisable to follow these recommendations:
- Strawberry seedlings before planting, rinse with water. Roots process salt solution (1 tablespoon. For 1 liter of water) by soaking for 15 minutes.
- Healthy seedlings are preferably treated with a disinfectant (aqueous solution "Parationa", "Fosdrina").
- Use the seedlings that were grown in healthy soil. Burn a seedling if you find even the slightest traces of parasites.
