A web tick on cucumbers - the best measures to combat pest. Effective methods and means of combating a spider tick on cucumbers Cucumber tick in a greenhouse

What it is?

Cobed tick - pest of orange, red, green and yellow or milky-transparent color. As a rule, the size of one individual does not exceed 1 mm, but there are also more copies - up to two mm. The insect feeds on the juice of the plant, so hitting the greenhouse, immediately looking for more juicy and delicious cucumber leaves. Drinking all the liquid from foliage, the pest kills culture: the bushes begin to filure, then fall and dying.

Since nutrients are concentrated on the bottom of the sheet, the tick prefers to shave it there. Poworkoys try to take as much space as possible, leaving behind small labels of the light white shade, which subsequently take the appearance of white stripes. Already after 3 days of the females of the pest, eggs are laying in an amount of about 400 pieces, and after the week, the colony of insects will increase significantly, respectively, they will need more food and pests will begin to attack neighboring plants. The main sign of infection at this stage is a web, enveloping cucumber shoulders.

Fighting pest on cucumbers

Fight him It is quite difficult, but quite real. You can highlight the following groups of necessary measures:

Prevention;
fighting local infection or defeat of foliage at the initial stage;
fighting the mass lesion of plants.

Biological and chemical preparations

For the struggle, when the colony of insects has already increased significantly, it is better to use chemicals. In this case, it is necessary to take into account that this pest is not insect, as such, so the insecticides are impractical against it.

You can destroy the arachnids with the help of acaricidal drugs that are conventionally divided into the following groups:

Please note that all acaricides in free sale have a third hazard class. This means that they are practically well-hazardous for mammals.

However, when they are used, compliance with elementary safety rules is required: respiratory system It is necessary to close the respirator, a gauze bandage or a piece of fabric. At the time of the procedures, wear clothes that covers the body as much as possible.

All work on the destruction of a tick in open soil held in windless weather. It is explained by two reasons: the accuracy of processing and protection against accidental hips. Moreover, when conducting medical events It is necessary to take care of environmental safety:

Do not work during flowering, since acaricides have toxic effects on bees;
prevent drug in open reservoirs, since acaricides are dangerous for fish.

To combat a spider tick Biological means (for example, phytodeterm) are widely used. The drug also has a third class of danger and when working with it it is necessary to comply with the same safety rules. But in contrast to the akiricides, the phytopreparations can be used during the growing season. After two days after treatment with phytodeterm, you can proceed to the harvest, while when spraying by ordinary acaricides - only a month later.

The main problems arising in the fight

It's quite difficult to deal with this misfortune. This is explained by two main reasons:

Ticks produce sustainable immunity to the chemical preparation used;
these sparrels are quite quickly multiplied.

Moreover, the pest is localized, as a rule, on the back of the sheet, which makes it difficult to detect it. Therefore, the processing of plants by acaricides must be carried out repeatedly.

The fact is that sometimes female ticks even until the death of death managed to postpone eggs that will not be subject to the destroying drug. Even if you spray plants at a time when the first females begin to eat, it will not stop the development of the population.

In addition, experienced vegetables argue that it is almost impossible to destroy the pests in this period that it is almost impossible to destroy pest colony. This is explained by the features Tick \u200b\u200breproduction: The greatest fertility of females is celebrated at the initial stage of plant damage. The number of eggs in one masonry can reach 300 pieces, and if we consider that incubation period It lasts only 7-36 days, then you can imagine how the population is growing. Therefore, even during the destruction of 90% of the ticks, there is a high probability of rapid recovery of the colony at the expense of the remaining individuals.

It is a large dose of the drug that has a destructive impact on all individuals, without exception. . In the process of use chemicals Some copies produce immunity, so small doses are not fatal for them.

Web tick on cucumbers in greenhouse

In addition to the main methods, the following are used:

After harvesting, the upper layer of soil is removed and the greenhouse design is performed (disinfection). With the onset of spring before landing, the procedure is repeated.
The sleeper is burned with a gas burner.
Fertilizers containing phosphorus.

Fighting folk remedies

Spraying soapy solution;
settlement of the territory of the fungus Endomophors of Adjara;
planting flowering plants.

What is dangerous by the web tick on cucumbers?

The tick can provoke the appearance of gray rot, striking the entire ground part of the bush. And the danger is not only the leaves, bloomrs and cucumber leaves, but the fruits themselves are exposed.

What to do?

Affected parts of culture are necessarily removed. It is also necessary to stop watering for several days, bring nitrogen-containing feeding, and spots on plants sprinkle ash.

The fight against the web tick is beginning with the adoption of prevention measures. With adequate carrying out the necessary agrotechnical events and compliance with all recommendations, the risk of cultural lesion is minimal. Therefore, there is every chance to grow and collect a rich harvest without losses.

According to experts in Russian Federation There are about 13 types of malicious ticks affecting vegetable cultures. The most dangerous representative of his family is a web tick. It is able to apply large-scale damage in a short time.

Cobed tick

The insect refers to the discharge of harmful arthropods. The most famous appearance occurs on vegetable culture - Tetranychus urticae (web) tick ordinary. Its dimensions reaches 0.4 - 0.5 mm in length, has a greenish or dark brown coloring.

Favorable climate for pest reproduction - Dry and warm air (Humidity below 60%, T above 25 degrees). Even by spending various chemical treatment, the web tick has a property very quickly to recover and significantly increase its colonies.

The insect initially settles on the bottom of the sheet, damages it and feeds on cellular juice, envelops the web. Gradually, the culture begins to yellow, and then dies.

The nature of the defeat of cucumbers

It is necessary to beat the alarm if such changes appeared on the cucumber leaves:

white dots or yellowish stains on the back side and at the base of the sheet;
singing, thin web;
drying and falling tops;
plant slows down growth.

Pest Methods

The cucumber tick is very dangerous for vegetables, to destroy it will be needed quite a few strength and patience, one spraying will not cope with him.

Processing of chemicals

It is necessary to apply measures against a spider tick when identifying the first signs of lesion of the plant. If the sheet has already begun to dry and a web appeared on it, it means that females put the eggs and soon the colony of pests will increase in tens and hundreds of times.

1. Phythoderm- has an impact not only on a spider tick, but on many other pests. To improve the effect it is necessary to combine with pyrethroids.
2. Fufanon-insectoacaricide having high toxicity with respect to ticks and other pests, and is also unsafe.
3. Apollo-acaricide, stopping the population. SO adult individualBut but kills eggs and sterilizes the female.
4. Union preparation, perfectly coping with any malicious ticks.

Undoubtedly, pesticides give the greatest effect in the fight against harmful insects, but possess not a small toxic effect on a person. At the same time, the web tick has learned to produce resistance (adaptability) to these drugs.

This method also has a minus: if the tick population has reached a massive infection, the predator is likely to do not cope.

Prevention - Pledge of Plant Health

Mandatory preventive measure from this pest is to prepare the soil to planting cucumber culture:

Getting Started, you should not have a seed or sprout too close to each other. If the correct distance is observed, this will allow you to quickly neutralize the plant affected by insects.

One of the main rules for the prevention of pests - care for the beds: planted vegetables need to constantly water, pour, removing the weary grass, periodically examine the leaves and stems. If the pest is still seen on the sprouts, immediately remove and destroy the infected plant. This action will help prevent the proliferation of the tick throughout the future harvest.

You can sow between the cucumber rows of dill, he will scare the tick with its smell.

If the landing is made in a secure ground, compulsory requirement - to conduct a chemical or heat treatment of the greenhouse.

The web tick is very hardy, resistant to weather conditions and chemical treatment facilities. But you should not despair, the spider monster can be defeated. If the cucumbers are correctly and timely care, the plant will thank the vegetable farm with a wonderful, abundant harvest.

Many complain that they are striking and lead to a damage of the crop. In our article we will tell, which represents on and how to deal with him.

What looks like

The pest carries a threat not only to cucumbers, but many others can be found on the crop, grown both in the closed and open

With such a pest, it is quite difficult to fight, so it is important to recognize it in a timely manner.

Important! The spraying procedure is recommended in the evening, since under the influence of sun rays, the chemicals will quickly evaporate and cannot destroy pests.

The tick is characterized by very small sizes. The female does not exceed 0.5 mm, and the male is 0.3 mm. Particularly voracious individuals, finding food suitable for themselves, for example, the juice of cucumber leaves can grow to 2 mm.

Pest body shape elongated, elliptical. The females are painted in orange-red, possess high fertility.

In the season of one female, to postpone about 8,000 eggs. Aging occurs very quickly - in just a few days, the egg becomes a hawk individual. If you do not hurry with the adoption of anti-pest measures, you can remain without a crop.

Than dangerous

The web tick causes great harm to vegetables. Suching the contents of cucumber cells, it gradually brings the death of the plant. Also, the pest is able to infect the plant with different infections, it will distribute bacteria, this leads to the fact that the plant loses its immunity and can get infected by others

Many are interested in the question: Is the web tick for a person dangerous? In this regard, you can be calm: the only harm (except for the loss of crop), which can cause a pest, is the nerves spent on experience.

Signs of the defeat of cucumbers

The main features of the lesion of cucumbers include:

Did you know? IN winter time Due to the lack of supply, the pest changes its painting. The colors of females becomes bright red or brown.

Usually, the web tick is located on the underside of foliage, so it is worth paying attention to it. A cobweb, Oviving Plants, serves as a springboard for moving pests by foliage. Damaged crops slow down their growth, and the leaves that were not damaged are yellow.

Prevention

So that the web tick does not defeat the cucumbers, the main measures of struggle must be taken - prevention:

It is important to remove vegetable remnants from greenhouses, as they are a place to winter pests.
Be sure to pull the soil - this will help move the ticks in the deeper layers of the Earth, in which he will not be able to survive.
It is necessary to carefully remove everything since the tick reproduction can occur.
Before sowing seeds, you need to rin the soil of 70% solution of colloidal sulfur.
It is important to constantly monitor how the plant looks like. If yellow points began to appear on the bottom of the foliage, it must be cut and burn.
It is recommended to alternate the falling down cucumbers with or
After harvesting, you need to remove the ground part from the site and burn it.

Important! If after processing it was not possible to overcome the web tick, infected plants need to dig and burn to prevent the propagation of the pest.

Observing elementary prevention measures, you can protect your harvest from the invasion of the web tick.

Methods of struggle

Fortunately, today there are many techniques telling about how to get rid of the cucumber ticks. Some gardeners prefer to use for this folk ways, and someone preferences "heavy artillery" - chemicals. In any case, it is necessary to remember that when processing plants it is necessary to follow security measures and strictly follow the instructions.

Chemicals

If you decide to seriously make pests, you need to use preparations against a spider tick. To the most efficient and common include:

Unfortunately, the web tick has the ability to quickly adapt to chemical preparations, so it is better to carry out a complex struggle with pest.

Some gardeners prefer to use folk remedies with a spider tick. We offer to familiarize yourself with several recipes.

Important! With severe drought or stable high temperatures Air Processing Plants should be carried out more often.

Dry-based recipe For the preparation of infusion, in the future cucumbers will be treated, it is required to use dry foliage, roots and stems montigating fluffy. The dry mixture is poured with water and insisted for 24 hours. It is recommended to use the proportion: 1 kg of a mixture on 10 liters of water.
Recipe based on fresh Borshevik. The green part of the plant must be confused to the kashitz-shaped state. Then it is necessary to add water to it (2 liters of water will be required by 1 kg of the mixture). After that, it is worth pressing the liquid part and the remnants of pouring 15 liters of water. It is necessary to insist for about 10 hours. After that, again you need to highlight the liquid part and connect it with the one that was squeezed before.
The recipe on the basis of the priestly crawling. From this plant will also have to prepare solutions, with which you can fight with a tick: 120 g of dry crushed gloss must be pouring 1 liters of water. After that, it is necessary to drain the liquid part, and the residue is diluted with water.

Cucumbers are not the simplest culture for growing. And this is due, among other things, with many diseases inherent in the diseases and attackers of pest cucumbers. One of the most dangerous pests is a web tick: it is not easy to detect it early, and it's not always to get rid of one moment.

Cute tick on cucumbers: who is

The faster, detect ticks on cucumbers, the higher the probability of the harvest. Therefore, it is necessary to know well what the danger looks like, and as many as possible inspect the leaves on the garden. Therefore, the dacket attending the site only on weekends, significantly risks to lose a full-fledged harvest.

The danger of a web tick

Carefully consider the tick can only a garden with excellent vision: it is a very fine insect, the size of no more than 0.5 mm, painted in a brownish-red color. With an increase, it can be easily viewed by four pairs of paws (while the insect is in the stage of the larvae - three). The larvae has a greenish color, on the sides passing into brown.

With an increase, you can consider ticks in detail; At the bottom of the figure shows the results of its activities

Ticks are winter in the thickness of the soil, they are plotted on the garden with the onset of heat and the appearance of sufficient for the proximity of the amount of greenery. In summer, insects prefer hot weather without precipitation. Females are postponed for about a hundred eggs, giving about 20 generations for the summer. The larvae hatch very quickly, in a few days. Self favorable conditions For reproduction of the tick - the temperature of about 30 o C and the humidity of about 60%.

Despite the fact that the life expectancy of the tick is small, no more than a month, his fertility is so high that it is a huge danger.

On the cucumbers, the tick prefers to settle on the underside of the leaves, where the juices of plants sucks, piercing the flesh of the sheet. Gradually moves to the stems, and then to emerging fruits, making tremendous harm. The top sections of cucumber plants are most affected. The dense web emanates both stems and leaves, disturbing the oxygen exchange and suppressing photosynthesis. The yield is significantly reduced: at best, almost twice.

Web covers all the plant, but it is not very similar to that web that weave the well-known home spider

Especially cozy with cucumbers in the greenhouse, because there are ideal conditions for his life and breeding:

sufficient amount of heat;
protection against wind and rain;
lack of eating bird ticks and large insects.

The tick changes its location with scraps created by their web. Perhaps "resettlement" and with the participation of human or animals, as well as weed plants. It is impossible to fully protect the landing from the tick: it can fly from anywhere with the gusts of the wind or "arrive" on any animals.

Signs of the lesion of cucumbers by a paustic tick

You can not always quickly detect the insect itself; More often, the consequences of its permit are first discovered. They may look like this:

light dots on the bottom side of the leaves, passing into merging spots;
barely noticeable, almost transparent milk-white web, entangling all the plant;
slowing down the growth of cucumber weaves;
yellowing or taking foliage with subsequent drying.

Of course, the yellowing of the leaves is characteristic of both many diseases, as well as nitrogenous fasting, but this is the reason to carefully examine the leaves, possibly using a magnifying glass. It is necessary to deal with the spider tick. It is necessary to start immediately: the procedure is long and sometimes, alas, ineffective.

Ways to combat a web tick

Despite the fact that the majority of gardeners prefers not to bind to the "chemistry", perhaps the tick is not the case, especially if the situation is launched. Nevertheless, in the early stages it is worth trying to do with folk remedies.

Folk remedies

Before processing cucumbers by any means, it is necessary to break and burn dead sections; The dead bushes should be dug and destroy completely. If possible, it is necessary to remove the resulting web. Next, if the web is a bit, landing is treated with one of the following drugs:

skipidar (spraying is quite dangerous, you can simply arrange several open jackets around the bed);
infusion of tobacco dust (spraying) or dry dust (dusting);
summer alcohol (teaspoon on 1 l of water);
hydrogen peroxide (2 tablespoons of 3% solution for 1 liters of water);
infusions or grasses of herbs.

Spraying spend several times with an interval of 3-5 days. For example, for example, for example, be used:

dandelion (500 g of greenery insist 3-4 hours in water bucket);
calendula (100 g of flowers on 1 liter of water, 4-5 days);
sorrel (300 g of chopped roots in water bucket, 4-5 hours);
onions, garlic (200 g of husk in the bucket of water, day).

Cuts can be prepared from yarrow or dope. Processing by any solutions or influence is carried out in cloudy weather.

Calendula - not only beautiful flower, but also the savior of many garden plants from pests

Chemical and biological preparations

Despite the high activity of chemicals, their use is not only undesirable (toxicity for people), but not always effectively: insects are quickly adapted to them. Therefore, biological agents based on the action of various microorganisms, for example, have greater applicability, for example:

Vestima;
Akarin;
Tickless;
Actor;

PhyTeerm - one of the most harmless drugs to protect many plants from pests

The most "heavy artillery" - acaricides that kill not only adults, but also affect the larvae, and even on the masonry of eggs. But, since for a person, such drugs are dangerous, it is worth a good to think about the feasibility of using them. This, for example:

Apollo;
Nisoran;
Flumite;
Floromite.

Such drugs should be alternating: the ticks quickly get used to their action, and no more than 70% of pests are destroyed in one processing. Therefore, it is worth paying attention to the prevention.

Preventive measures

Prevention of lesion by tick includes:

pumping bed after harvest;
disinfection of the sleeper;
the destruction of weeds and plant residues;
robust planting cucumbers;
looking nearby Calendula, Ukrop, Issop and other fragile herbs: they attract God's bows, which at the same time destroy and TRU;
timely destruction of dried leaves.

The web tick is the most dangerous pest of cucumbers, completely escape from it difficult, but if you find a pest in time and start the struggle, you can preserve the bulk of the crop. It is desirable not to bring the case to the use of toxic drugs, but to rely on affordable harmless folk remedies.

What is a web tick

Harmful web tick on cucumbers is an insect of milky-transparent, green-yellow, red or orange. As a rule, its dimensions are less than one millimeter, but sometimes their dimensions reach 2 mm. As soon as the bug was inside the greenhouse, she chooses the most juicy plants: insect the juice of cells for nutrition. Drinking all the liquids from the foliage of cucumbers, the tick "kills" the culture: the plant dries out, then falls, dies.

What looks like

The bottom of the sheet is rich nutrient substancesTherefore, the cucumber tick in the greenhouse will prefer this location. Insects seek to fill in the maximum space, leaving on their way small light-white tags: stains gradually turn into white stripes. Three days later, the settlement of the insect female will leave eggs in an amount up to four hundred pieces. After a week, the number of pests will increase significantly and to eat, they will destroy more plants. They can be seen, and the web is an indicator of the appearance of the colony of pest beetles.

How to deal with a spider tick on cucumbers

The fight against the spider tick on cucumbers can continue for a very long time. Sometimes it does not help the methods that worked before all hundred. There are several basic aspects that will help bring the pest. First, experts advise when landing seedlings alternate cucumbers, tomatoes: in the second pest, it is problematic to multiply, and he will not be able to move to the next bush. It is important to pull out weeds in a timely manner, as insects winter on them.

Humidity plays great importance: 80-85% is acceptable indicators for cucumbers, but intolerable for pests. It follows from time to time to water, loose, mulch the soil, while performing a high-quality inspection of plants at the time of the presence of insects. It is important that the injured leaves are best to burn. If prevention did not help, and the web tick on cucumbers remained, it is necessary to spray the bushes with drugs every two weeks. In case of expansion of the colony of pests, procedures should be participated.

Another way to destroy the creator is the population of a predator tick, for example, phytosayulyus. It will destroy the pest, while not disturbing the plants. If these methods did not come up, then you should contact toxic substances, but do not forget about safety techniques. Read the instructions carefully and use your own protection tools: respirators and so on.

Chemical preparations from a paustic tick

There is a large range of funds that are easy to buy in the online store. One of these is the actara. After half an hour after spraying the drug, insects are satisfied with poison, and after a day - die completely. It is important to read the instruction carefully, because your dose of the drug is calculated on different pests. The "Plant Pin" sticks must be placed in the soil near the bush or seedlings. When plants water harmful substances The drug is dissolved and killed by ticks. In the same way, Etisso is valid against the tick

Working with any chemical preparations, it is worth paying great attention to the safety technique: using accuters, it is necessary to wear a gauze bandage and gloves. After use, clean your hands thoroughly. To kill web ticks, you must open an ampoule, dilute it on a liter of water and spray the leaves of plants. Phytodeterm is another high-quality tool to derive insects, however, when the instruction is violated, the tinner adapts to the poison, and the result will be deplorable.

Price

The cost and price of chemical preparations is different, for example, the Aktara preparation can be found for 100 rubles with a little, and the price of the Etisso means can reach or exceed 1000 rubles. However, the quality of these drugs is different, and they should be used at different times of infection: the first - at the initial stage, and the second - when there are already serious problems: there is a risk of losing the entire harvest irrevocably.

Folk remedies

If you are afraid to choose chemicals and want to fight ticks, there is always an alternative: inexpensive means and folk methods. How to get rid of a pawless tick in a greenhouse? You can use the infusion of onions: it is necessary to pour 20 grams of the husk liter of water and leave for 6-9 hours, then spray with this solution. Either make a mixture with a medicinal dandelion: Dilute 30 grams in a liter of water. Finely grated garlic (proportions coincide) is also suitable as a means of protection against pest.

there is folk remedy From the velvetsev: pour dry flowers with warm water in relation to one to two and leave for two days. Stretch infusion, add about fifty grams economic Soap. This solution is perfect for spraying seedlings to kill the paustic tick. You can use Potato Botato: Pour 1-2 kg with warm water. After the solution lasts four hours, it is plentiful to pour infected bushes. Not only the tower, but also the wave, caterpillars die.

Prevention of the cucumber tick on cucumbers in the greenhouse

In preventive purposes, all folk methods can be used. With their help, it is easy not only to protect the cucumbers from the spider tick, but also enrich the vegetables with useful substances and minerals. Another unusual method: to use the greens of tomato. Receiver:

In 10 liters of water, it is necessary to put about four kilo tops.
Boil the mixture for half an hour.
Add 50 grams of soap economic.
Concentrate to dilute with water one to one, process plants and soil.
