Description of the parasite - a round worm, plant pest: what looks like, photo

Nematode, Latin name NEMATODES, refers to the type of round worms and primary genera. Different types of such plant pests have different sizes that fluctuate within 1 to 2 millimeters. The worms are translucent and painted white or milk. Different species parasitize on different cultures, and different parts of the plant. For strawberries, a leaf and stem nematode is considered especially dangerous. This is what a photo of the worm that exterminates strawberries looks like:

Here's a description of the parasite:

Adults of these species reach sizes 0.5-1 millimeters.
Men's individuals are less female. Their dimensions vary from 0.435 to 0.562 mm. Women's larger from 0.525 to 0.685mm.
Men's individuals are lighter.
In addition to strawberries, they can parasitize on tomatoes and chrysanthemums. Therefore, such cultures cannot be alternated one after another and planted nearby.
The most favorable temperature for their reproduction is not lower +22 ° C. They love soils with a level of acidity pH from 5.5 to 5.8.
The mouth gap is equipped with a biting device.
After destroying the surface layer of the sheet or stem, the nematode injects its secret inside the cells, which processes the juice of the plant into food. Such a mixture becomes the main product for the pest.
Together with the secret, the pest introduces plants and fungal diseases to cells.

It should be remembered: Nematoda females are capable of laying eggs from which offspring appears in quantity from 8 to 20 clutches per season. In each masonry, there is usually about 1000 eggs.

In adverse periods, female individuals form cysts. These are well -protected capsules that retain their viability up to 10 years. For plants, a pest accumulation is dangerous, exceeding a thousand individuals per 1 square meter.

Reasons for the infection of strawberries by nematode

Why do parasites harm plants? Below are the reasons for the infection of strawberries by nematode. Pests and the development of the disease can occur for two reasons:

Incorrect land planning
The most common way of infection is the acquisition of infected planting material.
Through the green parts of the plant - mustache and leaves parasites are crossed to new plants.
Poorly obscured beds are also bad for plants.

In the case when crop rotation is not respected and strawberry beds were broken after nightshade. At first, the disease manifests itself on one or a pair of bushes, with an increase in temperature, the disease spreads on to neighboring plants. With frequent rains or irrigation, increased humidity develops at high temperature.

Signs of strawberry damage by nematode

Due to very small sizes, it is difficult to notice pests on strawberries. But there are signs of strawberries with a nematode. The first noticeable manifestations of the presence of nematodes are:

The presence of yellow-brown and red spots on the leaves located along the veins
Redness of the cherries
Hardening the leaf plate
Reducing the size of the bush
Deformed outlet
Formation of very short mustaches
Lack of villi on the bottom of the leaves

As a rule, all signs are noticeable already when a large number of pests appear.

This is what strawberries look like a stem with a nematode

It is important to notice the parasite right away that it is timely to remove it. What does strawberries look like, affected by a stalk with a nematode? More visual symptoms of affected bushes can be called the following:

Plants are poorly developed
Green leaves acquire more intense staining and glossy shine
On the top of the sheet, leathery brown seals similar to galls appear
The flowers dry out
The central part of the bush dies, the outlet is deformed

If you dig a bush of strawberries, white small thickenings are noticeable on the roots with the naked eye. These are Nematoda cysts. Some gardeners confirm their guesses in the following way:

Several leaves and stems are cut into pieces, placed in a container and poured with cold water.
Hold up to 4-6 hours.
When studying water from a container under a magnifying glass, you can find small villi that move.

Where does the nematode come from on strawberries: how does it spread?

How does a parasite appear on plants? Where does the nematode come from on strawberries, how does it spread?

Larvae and adults in the cold season experience in earthen comments.
When heat occurs, nematodes move to the plant.
Through the overgrown adult nematodes, it moves from one plant to another.
Therefore, islands with affected bushes appear from the end of May and in the first decades of June, during the period of intensive growth of the bushes.

You should be careful when buying planting material from other gardeners so as not to put uninvited pests into your bed.

How to distinguish a nematode from a strawberry tick?

Symptoms of strawberry bushes with a strawberry tick and nematode are very similar. They develop poorly, the leaves wrinkle and change their color. You can distinguish a nematode from a tick only when considering them under a magnifying glass. For this, the leaflets are poured with water and left.

Nematodes have an elongated shape, and strawberry ticks are round.
Adults Nematodes settled on strawberries, tick only on the leaves.

The methods of combating the parasite also depend on which pest settled in the garden.

How to deal with a nematode on strawberries: Means

Experienced gardeners have long known this inconspicuous and insidious pest. Therefore, to combat it, there are already many different ways of struggle. How to deal with a nematode on strawberries, how to get rid of? What are the funds? All methods can be divided into several groups:

Processing of strawberry bushes with folk remedies. Memorial processing techniques, which include all kinds of methods of destroying adult nematodes and eggs.
Agronomicassociated with the methods of planting plants and cultivation of the Earth.
Chemical methods. Currently, the most commonly used. But they are not completely effective.
Biologicalassociated with the strengthening of the immunity of strawberry bushes.

Usually start with the simplest and most low -cost. And then, making sure of their inefficiency, they move to more time -consuming. Read further.

Folk methods of combating a nematode on strawberries: Means

It is worth noting that folk methods of combating a nematode on strawberries are the simplest, but very effective. This group of funds includes mechanical methods of struggle:

Exposure to the pest with temperature

Adults die when exposed to hot water on them. Strawberry bushes are dug out of the ground, cleaned and washed with cold water. Then they are kept in containers with hot water, heated to temperature +40-45 ° C. Loosing time fluctuates 5 to 20 minutes. At +50-55 ° C Eggs and cysts die. The main thing is not to exceed the temperature so that the plants retain their viability.

With a slight lesion of the bushes, ordinary watering with hot water is possible, the temperature of which does not exceed +55 ° C. A stream of water from the watering can be directed to the center of the bush. The option with the use of black agricultural light is possible. Under it in strong heat, the soil temperature sometimes exceeds +50 ° C, which will lead to the death of nematodes in the ground.

Soaking planting material in hot water eliminates the parting of strawberry bushes before planting. It is especially important to do this before planting purchased material.

Soaking planting material in saline

They take half a bucket of hot water 5 tablespoons ordinary table salt. Plant roots are pre -washed and for 15-20 minutes Soak in the solution.

Other plants

Alternative means to combat pests can be called plants that the parasite itself does not like. From here the next group of folk remedies appeared:

Plant infusions that are poisons for nematodes.
Such plants include marigolds, nasturtium, calendula or marigold.

Flowers are used to prepare infusions:

Recipe No. 1 - A kilogram of marigold flowers take 5 liters of hot water. The flowers are placed in a container and poured with hot water. Insist for 2 days, then filter and spill strawberry bushes. They process strawberries every other day, at least 5 times.
Recipe No. 2 - 200g calendulas (nails) are poured with 5 liters of hot water. They maintain 2 days, filter and water the strawberry bed every other day.
Recipe No. 3 - Nasturtium is prepared at the rate of 300 g of flowers per 5 liters of water. After 2 days of insisting, plants are watered once every 2 days.
Recipe No. 4 - The infusion of hogweed is prepared at the rate of a pound of raw materials for 5 liters of hot water. Insist two days and water the bed once every 5 days.

It is necessary to remember: Borshshik is poisonous plant for humans. Therefore, if there is a need to prepare such an infusion, it is necessary to observe special caution and use protective gloves and glasses.

Onion infusion

For cooking, take 200 g of green onions of the Batun variety. Pour hot water and insist on the day. Then water the bed once a week.

Every year, gardeners either find new means of combating a nematode or refute the effectiveness of existing ones.

Treatment of Nematodes of strawberries by agrotechnical wrestling methods

Strawberries not infected with nematodes

To prevent infection of new strawberries, affected plants are dug and remove. Neighboring bushes are checked for pests. Treatment of nematodes on strawberries is also carried out by other agrotechnical struggle methods. Be sure to do the following:

Before planting strawberries, finished compost or humus is brought to the sitethat will not only replenish nutrient reserves, but also improve the quality of the soil. They will add useful microorganisms that are detailed on roundworms. Lime and wood ash are brought into the ground to remove the possible acidity of the soil.
It is important to comply with crop rotation. Strawberries can be planted after onions, peas, beans, cucumbers or pumpkin. After tomatoes only for the fourth or fifth year. Avoid the proximity of strawberry beds with chrysanthemums.
The aisles in the garden are dug up in the spring and for the winter.
Rows must be covered with a black film, to maintain moisture and prevent nematodes.

Cross the beds to another place after 4-5 years.

Chemicals to combat nematodes on strawberries

It is worth noting that chemicals to combat nematodes on strawberries are used as an extreme measure, after the use of folk or agrotechnical agents. To destroy the nematodes and eggs with which the pest reproduces, special drugs that have a non -alarmic effect are used.

Attention: When working with such drugs, care should be taken and used by individual protective agents, gloves and glasses. And with the manifestation of signs of poisoning, it is necessary to contact medical institutions for help.

Before using the drugs, you should carefully read the instructions, and observe the dosage modes of insecticides. The following drugs have proven themselves well:

Heterophos - The most potent drug with a systemic contact action. Spraying of plants and the trunk circle is carried out at air temperature not lower than +20 ° C. It must be remembered that during 45 days After processing on the site, no work cannot be carried out.
Phospamide - Systemic insecticide of contact action. To combat parasites, three -time plant processing with a break is used in 5 days. It should be remembered that the toxic effect of the drug persists for another three weeks. The latest processing is carried out a month before harvesting. With proper use, in addition to adult individuals and eggs, cysts are also destroyed.
Mercaptofos and Lindan - Analogs Phospamide. They need to be used according to the instructions for the drugs, observing all precautions,
Purezin - A pharmacy drug, 10 tablets dissolve in a liter of water. Then pour the affected strawberries under the root.
5% solution of copper sulfate. Careful spraying of both the bush and soil in the spring, during the start of the growing season, is carried out.

Without fear of accumulation of toxic substances in berries and plants, you can use Fitoverm - The drug on a biological basis. To guarantee the complete destruction of nematodes, including cysts, 4 multiple processing of the beds with a break is required in 5 days.

How to get rid of a nematode on strawberries: Siderates

With the beginning of growth, view all strawberry bushes in the garden. To enhance plant immunity, add humus or finished compost, wood ash or mineral fertilizers containing potassium. Throughout the growing season, the beds are processed by growth stimulants. This enhances plant immunity.
Control strawberry beds for nematodes constantly, from spring to late autumn.
When the first signs of the presence of the pest appear, the bushes dug up, rinse their roots or soaking in hot water. Neighboring bushes are subjected to careful examination. If the bush can no longer be cured, you just need to burn it.
For the treatment of sick plants, first use plant infusions. And then, if the treatment is ineffective use insecticides.
Autumn revision is required. Remove the damaged bushes and then burn.
Carry out autumn introduction of potassium-phosphorus fertilizers.

In the strawberry bed, you have to work almost weekly.

Errors in the fight against nematodes on strawberries

When carrying out work with strawberry bushes, which have all the signs of a non -seniority with a nematode, we must not forget the most important thing. These are the mistakes often make gardeners when combating nematodes on strawberries:

Infected plants are forbidden to collect in heaps and leave them on the site, they should be immediately burned,
The washing waters obtained after washing and soaking the roots of strawberry bushes also require disposal. It is better to collect them in a separate container, which then warm or boil well. This will allow water to disinfect.

Often gardeners forget about crop rotation. If a nematode was previously discovered on the site, it is desirable to keep a diary of cultural plantings.

Nematodes on strawberries

Prevention from nematodes on strawberries is a set of measures aimed at preventing plant diseases on the beds. Starting from the first steps of planting the beds:

Prepare the site ahead of time. It is advisable to sow siderates in the selected place at least 2-3 years. Carry out a deep digging of the site with preliminary introduction of organic fertilizers and wood ash.
Check the new purchased seedlings before planting in the ground. To disinfect the roots of the seedlings, wash and soak in hot saline. It is forbidden to plant tomatoes, potatoes, carrots next to the strawberry bed.
Be sure to spray the bushes on new beds with growth stimulants And carry out regular top dressing with organic and mineral fertilizers. In the bed, plant plants that scare off pests - nails, marigolds and nasturtium.
In the fall, carry out a new revision of all plants, if necessary, processing with chemical nematocides.

Demote and wilted bushes discovered after the autumn revision, with the subsequent burning.
