Salted cucumbers and tomatoes are not cooked without fragrant leaves, so horseradish grows in each garden. This perennial does not require special care, and we must try to horseradish stopped in growth, withered or died. Only diseases and pests that can turn greens into a sieve are a threat.

Copper plant spelled copper

- If horseradish bushes are planted too close to each other, then with steady wet weather they may develop WHITE DECAY. The spores of this disease are transmitted through the air, and can spread from the weeds, says the gardener Irina Ivanova from the farm Vertyachy of the Gorodishchensky district. - Therefore, the spice is better to plant in well-lit places, place less often.

If the plant is still withered, you need to treat it with copper-containing drugs, fungicides. Well helps spraying Bordeaux mixture and hydrogen peroxide.

To prevent the infection from spreading, the diseased leaves need to be broken, added to the bed of humus or mineral fertilizers.

“It happens that the leaves of horseradish turn white, then change their color to dark red or brown and after some time start to dry out,” the expert continues. - This is a false floury dew. It affects not only horseradish, but also other vegetables - for example, cabbage, radish. To get rid of it, it is also necessary to spray the plants with copper-containing preparations.

Another disease that is to be feared is ASCOHITOSIS. This attack appears brown with a yellow tinge on the leaves. The nature of the disease is fungal, and when the mycelium grows, it kills the plant.

- It should be borne in mind that ascochytosis spores persist in seeds and soil, - warns Irina Ivanova. “Therefore, in order to get rid of this disease, you need to plow the garden well, neutralize the earth with a weak solution of manganese and treat the affected horseradish leaves with Bordeaux liquid.

Fans of little sharp

Spicy taste of horseradish fell in favor of not only people but also insects. Surely you have seen the leaves, studded with small holes. This is the work of WAVY BLOCKS. She herself is black, with yellow stripes on the wings. In early spring, this pest wakes up, females lay eggs in the soil, and 10-14 days after that, the offspring begins to grow and eat the plant.

- In this case, again, a good digging of the garden in the autumn will help, so that the remaining eggs of the pests simply freeze out, the hostess recommends. - It will be useful to scatter a mixture of wood ash with tobacco dust over the surface of the ground. By the way, this mixture can be sprinkled with vegetables, if you notice that small holes appear on the leaves of the seedlings.

CABLE BUTTERFLY also applies to lovers of horseradish. It can often be found in the garden - it is a light-brown insect. Just like a wavy flea, the offspring is dangerous - kids hatch in June and devour horseradish on the vine. Only insecticides will help against these reptiles.

- Sometimes on the leaves of horseradish can be found and the so-called red soldiers - red bugs with black spots on the back. In fact, this is a CABBAGE BLOCK, - says Irina Ivanova. - It feeds on the juice of young horseradish shoots, thereby destroying the plant. Dark spots appear on long leaves, the leaves themselves turn yellow, dry and fall.

Folk remedies will help scare away any pests - treatment with soapy water or tobacco dust, as well as a decoction of onion peel or chamomile. However, it should be emphasized that these are only preventive measures. If insects have already taken up the harvest, you need to resort to more radical actions.

Horseradish pest control methods

Horseradish is often grown in vegetable gardens and suburban areas, and the process of breeding this herbaceous perennial is not difficult - horseradish is unpretentious either to the soil, or to care, or to watering and fertilizer. The main purpose of its cultivation is the usefulness of the root.

Unfortunately, not only people, but also insects, who also prefer to eat it as food, than strongly damage the plant, consider it useful. We offer to get acquainted with the most common horseradish pests and methods to combat them.

He likes to feast on leaves of horseradish, as, incidentally, all other plants from the cabbage family, babana or cabbage (horseradish) leaf beetle. It is these small (3-4 cm) dark greenish beetles and their larvae gnaw the foliage so that sometimes one sieve is left from the leaves. In early June, in search of food, these beetles leave wintering grounds.

The females lay eggs in the eaten sheet plates and the new offspring appears as early as August, damaging the plant over a three-week period. After that, the insects begin the process of pupation.

Methods of struggle.If you find extra holes on the plant, but you can’t understand why the horseradish leaves are all in holes, we recommend that you immediately remove the damaged parts. In case of a massive defeat of a plant, it will be necessary to carry out a deep digging of the soil, followed by treatment with insecticides. To do this, the drugs "Fury", "Aktellik", "Karbofos", "Inta-vir" and others.

With an insignificant spread of pests, mechanical processing is recommended — the collection of beetles and larvae by hand and shaking them onto a litter. Also well proven and glue traps.

As an alternative method of dealing with babanukha, dusting can be carried out with a dry mixture, which consists of: 1 cup of wood ash, 1 teaspoon of dry mustard and ground red pepper. This treatment should be carried out at least three times with an interval of 4-5 days. From plant insecticides recommended treatment with decoctions of yarrow, chamomile, sage.

Since the beetles hibernate under unclean foliage and in the soil near the roots, in order to prevent an invasion of cabbage or horseradish leaf beetles, in the autumn period you need to remove dry plant residues, dig the soil in the root zone, and also remove weeds in time.

Wavy flea

Another unpleasant guest for a vegetable garden where horseradish grows, often becomes a wavy flea. This microscopic size (3 mm) beetle can cause great damage to the plant. It can be recognized by its black color and yellow stripes on its sheaths. Just like babanaha, the flea eats leaves, eating out through holes in them. It begins its sabotage in the first month of spring. The females lay eggs on the soil surface, causing horseradish leaves to dry out and the plant to die.

Methods of struggle. In order not to let the wavy flea in your garden, in late autumn you need to remove dry leaves and carefully dig the soil. Also recommended periodic loosening of the soil under horseradish during its growth. Since before the appearance of leaves of cultivated plants, pests feed on weeds, we must get rid of them in a timely manner.

If the wavy flea still occupied your area, then for the treatment of horseradish from these pests, you can use the drugs "Foksim" and "Aktellik". Spraying is carried out three times: in the period of emergence of sprouts, at the beginning of the nomination of buds and after flowering. You can also use vegetable insecticides - in this case, you should choose drugs that contain tobacco in their composition.

Also, an effective way would be to use sticky traps (made of glue, honey, grease, etc.) applied to the leaves of the plant or paper caps to cover horseradish.

From folk remedies you can try dusting a dry mixture of ash, mustard and red pepper (prepared as in the fight with babanukha). Also popularly used spraying a solution of vinegar (1 cup of 9% vinegar in a bucket of water), garlic-tomato infusion (and 1 cup of chopped garlic and tomato tops to dissolve in 10 liters of warm water, add laundry soap), a decoction of tansy.

Cabbage Mace

Horseradish larvae are also enemies of the moth - cabbage moth. The butterfly itself is small and with a wingspan of 3 cm. It has a brown body with dark stripes on the front wings. Caterpillars winter in the soil, and come to the surface in June, after which butterflies immediately appear. Females lay eggs on the underside of the leaf. After 10 days there is a voracious offspring, which gnaws the leaves of horseradish for a month. Then it goes into the ground for pupation and wintering.

Methods of struggle. Preventive measures against these horseradish pests are used the same as in the attacks of the parasites described above. Horseradish should be planted as soon as possible - before the appearance of butterflies. For mass infections, anti-parasitic insecticide treatments are used.

Diseases of horseradish and methods for their treatment

Ascohitosis. The disease occurs because of the fungus. On the plant, it appears as follows:

  • Yellow-brown large spot on the leaves,
  • light mycelium on the affected parts (wintering place of the fungus),
  • cracking, damage, falling leaves where there were spots.

The main factor in the development of askohitosis is a wet environment. The fungus continues to live on plant debris, seeds and soil.

White rust. The disease is manifested on the stems, leaves and peduncles in the form of light yellow spots. From their reverse side there appear brilliant light pads filled with spore powder. After harvesting, the fungus will overwinter in the roots or plant residues.

Cercosporosis. The diseased plant is abundantly dotted with small patches of gray-brown with a brown border. After the rain, they are covered with a gray blotch of spores. After a few weeks the specks merge into larger formations, which then dry up, crack and die. The disease is able by the middle of summer to make the plant dry out completely. The pathogen is stored in plant debris.

Downy mildew (peronosporosis). In the case of horseradish disease manifests itself in the form of pale green spots, which on the reverse side have a gray plaque (spores). Spots grow, become brown and die. The disease in case of strong development is able to destroy all the leaves and greatly weaken the root system. The fungus overwinters on plant residues.

Council To overcome these diseases, it is necessary to trim the damaged parts of horseradish and remove all post-harvest residues. In case of severe contamination, spray a garden bed with Bordeaux mixture or other substance containing copper sulfate.

How to get rid of insects that have chosen horseradish

Among the most common horseradish pests - babanuha or cabbage leaves: black with a green tint bug. He is a private guest on all members of the cabbage family. The insect lives and overwinters in the soil under fallen plants, lumps of manure, etc. In early summer, the bug moves to the leaves of horseradish: gnaws holes and lays eggs there.

One female babanuhi produces up to 400 individuals of offspring. For prevention in the autumn, pick all plant residues from the garden bed. Fight weeds: field mustard and wild radish. Also effective are the following measures:

  • crop rotation,
  • early planting of seedlings
  • post-harvest trenching,
  • spraying of 0.15% aktellik.

Wavy flea - Another pest of horseradish, common in the northern and humid areas. This black beetle up to 3 mm long has one characteristic strip on the elytra. In early spring, the pest moves from wintering grounds to horseradish and other cabbage representatives. Flea eggs lay on the ground under the plant. Yellow larvae emerge from them, which feed on small processes of the root system of horseradish. Then a second, summer, generation of a wavy flea appears, the target of which is the leaves.

Also on horseradish you can meet these pests:

Against pests are good:

  • removal of all horseradish residues from the garden,
  • weed control and other phytosanitary measures,
  • spraying with copper preparations,

  • regular and intensive soil loosening,
  • spraying with insecticides (0.1% actellic, 0.1% foxim, etc.).

Tips in the fight against diseases and insects. Preventive measures

Horseradish is actively used as an ingredient in infusions and solutions against different groups of pests. However, the culture itself has many “enemies” in the garden. The main popular weapon against the majority of fungal, viral diseases and pests is keeping clean in the garden. Spores and pests feel great in cold weather under a layer of foliage or organic debris.

If you are going to plant horseradish in spring, prepare the ground in autumn:

  1. Observe the alternation of cultures. If planting horseradish - the first, then make sure that the bed is far from the place where the roots or tomatoes grow or will grow in the next season.
  2. The landing site should also not be too wet.
  3. Remove all fallen leaves from the trees, plant residues.
  4. Loosen the soil thoroughly.

So you harm the wintering pests and fungi. This is 50% protection for the plant. Since spring, it is important to continue to regularly loosen the soil and notice the first signs of the appearance of diseases or pests.

Horseradish leaf beetle

This vegetable is a valuable medicinal crop, the birthplace of which is the south-east of the European part of Russia. It is grown for the sake of a cylindrical weighty and fleshy rhizome, which is used as a food and spicy plant. It has a horseradish root sharp and pungent odor. It tastes sweet at first, later becomes hot and spicy.

Horseradish pests include babanukha or horseradish leaf beetle. Adults and larvae love to nibble at its leaves. Such beetles are pests of a length of 3-4 cm, oblong-oval in shape with a convex back and dark green elytra. Females tend to lay eggs in their flesh and pour them into secretions. The larvae live in groups and harm horseradish for about 3 weeks. Favorable for their livelihood cloudy weather and humidity up to 100%. Pupation of larvae occurs in the ground.

The fight against them involves the destruction of diseased crops, deep soil digging, spraying insecticides. The Fury remedy performed well - it should be used at the rate of 1 ampoule per 10 liters of water. Collect parasites advise hands. From folk remedies, the use of wood ash in combination with hot red pepper and dry mustard is popular. This composition at the rate of 1 cup of ash and 1 teaspoon of pepper and mustard, should be powdered horseradish.

White rot

Another pest for normal growth of horseradish is a dangerous infectious fungal disease - white rot. For the development of this disease in horseradish requires good moisture of the soil and air. Spores of the disease are usually carried along with the wind, spread through planting materials, weeds. The richness of nitrogen in the soil and the excessive density of horseradish plantings are favorable for them.

The fight against this disease includes the use of copper-containing fungicides. Bordeaux liquid will do. Against such a disease, which occurs in horseradish, use of contact action drugs Ditan M-45, Profit, Rovral, which can not always help. It is recommended to treat horseradish with means related to system-contact fungicides - Ordan, Previkur, Profit Gold, Acrobat MC, Ridomil Gold MC. Prevention - weed control, destruction of affected crops, plowing the ground in autumn, liming sour soil, a balanced composition of mineral supplements.

One of the diseases that affect not only horseradish, but cabbage, radishes and other crops. Those leaves, stems, testes and horseradish stalks that have undergone this most dangerous disease turn out to be covered with white oil paint. As the disease develops, horseradish tissues become brown in color and dry out. The leaves look bloated and are deformed, because they form spores of the virus. Methods to combat this disease include spraying with copper-containing agents.

Plant residues must be removed from the site. For the prevention of the disease should be mercilessly destroying weeds in the process of growth of horseradish and adhere to the rate of crop rotation.

Cabbage bug

The symptom that your horseradish is struck by the cabbage bug will be yellowed leaves, on which dying spots will later appear. The adult bug has a flat red body with black spots 8-10 cm long. The females lay eggs on the underside of the leaf plate. The active development of larvae occurs in the first month of summer, with the onset of the first hot days. The larvae and adults suck the juice from the leaves and shoots. Hibernate in post-harvest residues.

Methods of struggle. To successfully combat this parasite, it is necessary to carry out preventive measures in the form of early sowing, periodic digging, destruction of weeds and plant residues after harvest.

You can also use repellents (in particular, the treatment of leaves with soapy water: 300 g of soap are diluted in a bucket of water) or use dry treatment with ashes mixed with sand and naphthalene, or tobacco mixed with sand and earth. Неплохой эффект дают и опрыскивания отварами ромашки, луковой шелухи.

При массовом поражении клопом (две и более особи на один куст) используются инсектициды «Актеллик», «Фосбецид», «Белофос» и др.

Аскохитоз хрена

The main symptoms of horseradish ascochitis are large yellowish-brown spots on the leaves. On the affected areas appears mycelium, where the fungus is the causative agent winters. In the future, the sheets dry out and fall off. A pathogenic fungus loves to grow in a humid environment, and is also able to remain in post-harvest residues, soil, seeds for a long time.

Methods of struggle. To preventive measures against ascohitosis include the observance of crop rotation, autumn harvesting and plowing the vegetable garden. For the treatment of the disease, the affected leaves are removed, treatment with 1% Bordeaux fluid or its substitutes is used. Note that it is better to spray twice, at intervals of one week.

Verticillary wilting

With verticillary wilt, the fungus-pathogen penetrates into the vascular system of horseradish. First, the lower leaves wither, and then gradually the whole plant. Spores of the fungus overwinter in the soil, and may persist there for several years.

Methods of struggle. If you suspect this disease, you must inspect the beds every 10 days, and remove diseased plants along with the layer of earth beneath them. After watering, deeply loosen the soil, as well as carefully destroy the remnants of plants after harvest and deeply dig the soil.

Downy mildew

Downy mildew or horseradish perinosporosis infects the leaves. First, they are covered with light green or yellowish spots, and on the back of the sheet plate forms a gray or whitish coating. Then the spots merge together, the leaves become brown in color and die. The plant becomes weak and gives a small root vegetable.

Methods of struggle. Since the main way of infecting plants with this fungal disease is affected seeds, they must be decontaminated before planting. At the first signs of the disease, diseased plants should be removed, and in the case of extensive spread of the disease, spraying with copper-containing fungicides is recommended.

Significantly reduce the risk of diseases and attacks of pests can be, caring for their garden and plants, making them strong and resistant. Preventive measures will be:

  • crop rotation and fruit change,
  • thorough weeding and weed control,
  • watering with cool water with the addition of plant insecticides,
  • fertilizer,
  • autumn harvesting of crop residues
  • digging deep.

All this will also help avoid the use of chemicals.

Diseases of horseradish and how to deal with them

Horseradish on the dacha plots is a permanent resident, because its benefits are obvious, and the breeding process is simple and straightforward. The plant does not impose special requirements on the soil, care, conditions of detention. The result of growing can not please, if there are diseases of horseradish.

Among all the diseases that can affect the plant, white rot is one of the most common. Conditions favorable for its development are high humidity of air and earth, excess nitrogen and planting density. Spores of the disease are transmitted through air masses and spread through planting material or weeds.

The fight against white rot is as follows:

  • the use of fungicidal preparations, which contain copper,
  • Bordeaux application for horseradish spraying,
  • systematic use of drugs of the contact group, for example, Rovral, Ditan M-45,
  • treatment of horseradish leaves from pests using system-contact fungicides: drugs Ordan, Ridomil Gold, Previkur, Acrobat MC,
  • preventive measures in the form of the destruction of the affected specimens, reducing the acidity of the soil and making mineral supplements with a balanced composition.

In order to exclude the occurrence of this disease in the next season, it is necessary to carefully plow the soil in the fall to get rid of excess moisture.

The main symptoms of this disease are brown spots with a yellow tinge, localized on the leaves of the plant. The affected areas are characterized by the presence of a mycelium. Pathogenic flora develops in an environment whose humidity is above average. Also, the pores that cause ascohytosis persist for a long time in the soil and seeds of the plant.

You can deal with the problem as follows:

  • carry out a thorough cleaning of the garden in the autumn with an inspection of all root crops for the presence of the disease,
  • good to plow the garden
  • observe crop rotation.

It is also possible to cure the plants affected by ascohitosis. For this, Bordeaux liquid treatment or compositions with a similar effect are carried out. To secure the result, it is necessary to spray horseradish from pests a week later.

Belle (downy mildew) is a disease that can affect horseradish, cabbage, radishes, and some other vegetables. Exposed to the causative agent of the disease, parts of the plant (stems, pedicels, testicles) appear to be covered with white paint, but as the plant grows and the disease develops, the color changes to dark brown or brown. Then the affected plant begins to dry, the root crop noticeably shallows. Practically the only means of struggle is spraying with copper containing compounds.

Horseradish pests and how to get rid of them

This plant is extremely useful - so consider not only people, but also insects - pests of horseradish garden, which cause damage to the plant, eating it.

The wavy flea is a black pest, on the wings of which there are yellow stripes. The greatest activity is observed in early spring: females lay eggs on the surface of the earth, and the offspring that appeared after a week and a half eats holes in the leaves of horseradish.

The most effective measures to combat flea include:

  1. Careful digging of the soil in the autumn so that the remaining insects froze.
  2. Cleaning of dry leaves is not in the spring, but in the autumn before the onset of frost.
  3. Loosening the soil under the plant in spring and summer.
  4. Cleaning the area of ​​growth of horseradish from weeds.
  5. The use of chemical preparations Phoxim and Actellic, as well as folk remedies, for example, a mixture of wood ash with tobacco dust.

The best time to use plant protection products is the time when buds appear and flowering begins. At this time, drugs will be most effective.

The second name of this pest is horseradish leaf beetle. Three-millimeter beetles gnaw up the flesh of the leaf to such an extent that they become like a sieve. To fight insects that are capable of harming a crop twice a season, it is possible with the help of insecticidal preparations, as well as through careful digging of the soil after harvesting.

If the scale of the damage is small, then you can resort to mechanical means to combat the pest: collect bugs with your hands, use traps on the glue, shake off pests on the litter. To consolidate the result, you can powder the plants with a mixture of red hot pepper, wood ash and ground dry mustard in a ratio of 1: 20: 1.

The larva of the moth - cabbage moth - is another enemy of horseradish, capable of bringing irreparable harm to it. A small insect, the maximum wingspan of which is not more than 3 cm, has a light brown body with dark stripes on the wings. The offspring appears in the middle of June, after which the young individuals gnaw the leaves of horseradish for a month.

Methods for dealing with firebugs are the same as for other pests. The list can be supplemented with the advice of planting horseradish earlier, so that by the time the butterfly is born, the leaf is strong, and the plant could bear the attack of the pest more calmly. If the infection is widespread, the use of insecticidal drugs is appropriate.

The main symptom that characterizes the damage of this pest is the yellowing of the leaves, the appearance of brown spots on them and the subsequent falling away of the foliage. The bug itself is an insect with a red trunk 8-10 mm long, on which black spots can be seen. The most active insect in June. After sucking the juice from the shoots of horseradish and its leaves, the individuals hide for the winter in post-harvest residues.

Preventive measures can be taken as follows:

  • early sowing of horseradish,
  • periodic soil digging,
  • weed control,
  • complete elimination of residues of plant material in the fall,
  • the treatment is made using repellents (soap solution mixed with sand and mothballs ash, tobacco dust),
  • treatment of horseradish pests simple folk remedies - decoction of onion peel or chamomile.

If the damage by the bug is massive and all the plants are threatened with destruction, then it is necessary to use insecticidal preparations: Actellic, Belofos, Phosbecid.

Causes of

Among horseradish pests in the first place is to put babanukha. This insect has other names - cabbage leaf, horseradish leaf beetle. In addition to these two cultures, babanah often attacks horse sorrel. These are bugs, whose body length is 0.35–0.4 cm. Insects are painted in dark green color, which look shiny and close in shape to a circle.

Babanukha usually winters in the surface layer of the earth, so its appearance is due to the inattention of farmers to neutralize this layer. Exit to the surface occurs in the spring. One can notice the manifestations of aggression first on the weeds, since the leaf beetle eats first of all cultivated plants. Eaten leaves are brought to the state of the skeleton. Every 12 days comes a new wave of the pest. The leaf beetle is active in cloudy, wet weather. Of course, it does not depend on gardeners, but it is recommended to carefully care for the plantings and remove all weeds, thus avoiding conditions for the appearance of a pest.

It is very important to engage in the prevention of diseases. If horseradish is healthy, it is much better resistant to insects. In addition, there is no need to intensely guess what caused the occurrence of holes or white spots on plants.

Holes in the foliage makes a wavy flea. Tiny arthropods should not set gardeners in a benign way. These “miniature” horseradish fighters can make a kind of sieve from a strong large sheet in 5–7 days. Recognize the insect by dark color and stripes of yellow tone on the back. It is almost impossible to collect them with your hands, because with the slightest movement, the jump instinct works. A wavy flea overwinters in the ground, so the indirect reason for its occurrence is also considered non-compliance with preventive measures. The insect brings the main damage already from the first days after the emergence of shoots, it develops the highest activity in hot dry days.

Cabbage moth is also a formidable opponent of the sharp plant. This butterfly has a wingspan of 30 mm. It is painted in brown tone, dark stripes can be seen on the front parts of the wings. The wintering of the caterpillars occurs in the soil, they are pulled out in June, and the formation of cocoons immediately begins. After 10 days, you can expect the most active aggression, when the second generation settles on the leaves. The danger lasts about a month, then the insects begin to prepare for wintering again.

Another pest is the cabbage bug. Recognize its invasion helps yellow foliage. If you do not deal with the effects of infection, it will soon become covered with necrotic spots. Flat red to black speck bug in length reaches 80-100 mm. He delivers the main blow against the backdrop of hot weather.

Prevention

Any negative event is easier to prevent than to overcome. To protect horseradish from pests, the following preventive measures should be applied:

  • strict implementation of the norms of crop rotation,
  • digging after cleaning,
  • planting seedlings as early as possible
  • use of safe deterrent drugs
  • soil disinfection.

The dug up earth helps to lay eggs of harmful insects upward. As a result, they freeze and in the spring can no longer give a new generation. An additional measure of protection is to sprinkle the entire surface of the beds with a combination of ash and tobacco dust. The same mixed composition is very well manifested itself for the protection of vegetable plantations.

Scare away the pests, but only as long as they do not start the "meal", it is worth such means as:

  • soap solution,
  • tobacco dust,
  • decoctions of husks of onions and chamomile.

At the stage of preparation for the first landing of horseradish should be checked so that tomatoes and root vegetables do not grow nearby. Moreover, the joint cultivation of them close to one season creates favorable conditions for pests.

It is recommended to choose the least wet areas and remove from the surface all fallen leaves, the remnants of past vegetation. It is very important to loosen the ground thoroughly. And you should also continuously monitor the state of horseradish landings.

Folk methods

If you failed to fully protect the hell thickets, and the pests are already attacking them, you will have to fight them more actively. It is not always advisable to use synthetic insecticides, since there are safer means. With a weak infection with horseradish babanukha, it is worth performing the following measures:

  • shoot it manually
  • apply glue traps
  • shake insects on the underlying material.

To consolidate success, it is required to process horseradish with a combination of 20 shares of wood ash, 1 share of red pepper and 1 share of ground dry mustard. Cabbage moth is suppressed in roughly the same ways. But if there is a lot of it, it is required to use synthetic means. With the invasion of a cabbage bug it is worth fighting with it with onion or chamomile decoction. Spraying the plants is not the only option, you should add to the horseradish planting nasturtium or marigold.

Long-lasting results provide a dusting of ash in combination with red pepper. It is required to sprinkle not only the leaves, but also the ground surrounding the plant. Suitable plant insecticide is a decoction of yarrow or wormwood.

Processing with natural preparations, including tincture of alcohol, should be carried out at least three times, leaving intervals of 4-5 days. This will allow to evaluate the effectiveness of the impact and, if necessary, to increase its intensity.

Chemicals

Treat horseradish store preparations need to be careful. Begin with a test on a single bush. Only when 24 hours have passed and no negative manifestations have been found, can the rest of the plants be treated. The use of synthetic reagents is recommended mainly for very severe infections. In such a situation, natural formulations with their effectiveness of about 30–40% are poorly suited.

Spraying should be carried out with strict compliance with safety requirements. By all means protect hands with gloves, and also put on points. It is recommended to wear a mask on the face, covering the mouth and nose. You can not consume fruits from plants treated with synthetic means before it takes 30 days. The drug "Fury" is used in the amount of 1 ampoule per 10 liters of liquid. The wavy flea is well suppressed by Foxim and Actellic. The very first treatment is carried out at the time of germination, then it is made at the beginning of bud formation and at the end of flowering.
