The radish leaves are all in the hole. How to treat radishes from cruciferous flea? General measures to prevent the development of diseases and attacks of radish pests

All gardeners want to get as many healthy fruits as possible from radish ridges with juicy tasty pulp, full of vitamins and minerals.

But not everyone manages to grow a good crop due to diseases and other reasons: sometimes radish pests get in the way, and methods of dealing with them do not always help. Due to insects not detected in time, vegetable growers may be left without radish fruits, but more often they still manage to be defeated with the help of insecticides.

At any climate zone there are plenty of insects that can harm radishes and other cruciferous vegetables. Before you learn how to treat radishes from pests, consider the main winged and crawling insects - the enemies of the vegetable.

cabbage moth. This is a small insect of a brown-gray color, whose wings are decorated with a dark fringe. It is not the moth that causes harm to the radish, but its larvae, which feed on the juice and tissues of plants.
cabbage white. This white butterfly with a black border around the edge of the wings is known even to children. She lays her eggs in radish plantings. Caterpillars hatched from eggs actively eat the lower part of the leaves, moving from rosette to rosette.
Garden and cabbage scoop. Sero - brown butterflies, making masonry on radishes. The larvae destroy the leaves, turning them into transparent skeletons. Plants attacked by a pest stop developing.
cabbage fly. It happens in spring and summer (the last fly has larger dimensions). An ash-colored fly that produces egg clutches on vegetable plantings, from which white worms hatch that infect the roots. The radish becomes unusable in 2-3 days.

cruciferous flea. The most dangerous enemy of this culture, eating the leaves of young plants: after its invasion, the tops resemble a sieve.
wireworm. The beetle larva is a nutcracker capable of destroying the entire plant, including the roots.

As you can see, the radish has a lot of enemies who want to feast on tender foliage and roots, reducing all the efforts of gardeners to nothing.

How to process radishes in the garden from pests

Such an extensive list of harmful insects that can destroy the crop is alarming. However, many insecticides have been developed against pests that can easily cope with misfortune: their list is no less.

Biological and chemical preparations against radish pests

Entobacterin

It is used in liquid and dry form: dissolve the product in water according to the instructions and spray the plantings, or spray the drug in powder.

Entobakterin - universal biological agent from various insects, especially well destroys the cabbage moth and its offspring.

Bitoxibacillin

Dilute 50-100 g of powder in 10 liters of water, add 40 ml of liquid soap and water the radishes over the leaves in dry weather.

biological preparation, safe for bees and pets, does an excellent job with a variety of harmful insects.

Actellik

We dissolve 20 ml in a ten-liter bucket of water and spray the plantings (this solution is enough for 10 m²).

Good remedy for cabbage fly and other winged enemies of the radish.

Zemlin and Provotoks

They are used according to the instructions against the wireworm and other pests that live in the soil: cabbage fly larvae, ants and others.

Bazudin

We fill three-quarters of a liter container with sand, mix with 30 g of the drug and add it to the soil when planting (the composition is enough for 20 m²).

How to treat radishes from wireworm pests? Just Bazudin: he also cracks down on bears, cabbage fly larvae, weevils, etc.

Initiative

30 g of the drug is enough to treat 15 m² Prepare a mixture of ¾ l of sand and 30 g of the product and scatter it on the ground around the seedlings.

The initiative destroys not only wireworms, but also those pests of radishes, methods of combating which are beyond the power of some drugs: caterpillars of scoops and whites, cruciferous flea, larvae of any flies.

Aktara

Universal insect repellent, used at the rate of 5 liters per hundred square meters. Kills aphids and caterpillars hatched from eggs of butterflies and moths. Dangerous for bees.

Aktofit also copes well with pests. A biological product, dissolved in water according to the instructions on the package, destroys aphids, cutworms, cabbage whites and many other insects that feed on cruciferous plants.

Folk remedies for radish enemies

How else can you treat radishes from pests? Folk remedies, especially if early varieties are planted, from which nitrates from chemicals do not have time to leave.

Ash and soap

We dissolve 50 g of laundry soap and 2 cups of wood ash in 10 liters of water, and water the radish on a fine, but not hot day.

The tool helps with the invasion of many harmful insects, especially cruciferous flea.

Ash and tobacco

Regularly pollinating plantings after watering or rain with tobacco dust or ash, it is easy to get rid of caterpillars and other pests of vegetables.

Pepper and mustard

Mix in 10 liters of water 1 tsp. powder of any hot pepper, 2 tbsp. salt and 2 tbsp. dry mustard. We water the plantings to destroy the caterpillars of the cabbage whitefish, moths and scoops.

If, after treating the beds with folk insecticides, it rained, we repeat watering or pollination, otherwise the insects will destroy the plantings.

Now it’s clear what radish pests are and how to deal with them - folk and industrial. Remember that for early varieties radish, only folk remedies or biological products that do not harm human and animal health can be used.

Agrospan protects radish from flea
Agrospan protects radishes from cruciferous flea

Although radishes do not have as many pests and diseases as, for example, tomatoes, they do exist and can destroy most of the crop. This article is an addition to great material about growing radishes.

It helps in the fight against diseases the observance of crop rotation on personal plot. Since radish is an early crop (harvest can be obtained in about 1 month), there is a temptation to return to the same bed with re-sowing after some time in the same season. Doing so is highly undesirable. Because it can lead to outbreaks various diseases. It is also highly undesirable to plant radishes after cabbage or other cruciferous plants. Good predecessors are onions, garlic, peas, beans, potatoes, tomatoes, cucumbers, zucchini, zucchini.

Pests

The main scourge of radishes is cruciferous fleas - small bugs, usually dark in color, jump well from place to place. They damage radish leaves (make holes in them). And if the damage to the leaf apparatus of the plant reaches a critical size, then the plant abruptly stops growing and may die. At the same time, the root crop does not ripen and does not grow to the desired size. Radish seedlings should be especially protected from fleas. Otherwise, crops can be completely destroyed (eaten). mature plant can still tolerate fleas to some extent. Fleas are especially rampant in dry, hot weather. Early crops of radishes can generally produce a crop before the mass appearance of cruciferous fleas.

The fight against the flea should be carried out by biological methods.
The first method is spraying on the leaves with a solution of wood ash. The solution is prepared as follows: about 2 cups of preferably fresh ash and 50 grams of laundry soap are added to a 10-liter bucket of water. Everything is mixed up. Some make it easier. They collect ashes on a shovel and crush them over the garden. For a while, the flea restricts its malicious activity.

The second way is the same. Only instead of ash they take tobacco dust. It should be said right away that tobacco dust still needs to be looked for in stores, and it costs, although not expensive, but still worth it. And the ash is usually its own, free.

All these methods are still not effective enough. The most effective is insecticide treatment, such as Inta-Vir. But this should be done only as a last resort, only for medium-sized radishes (ripening time 25 days) and only for young seedlings, if the threat of destruction of crops is large enough.
Another exotic (mechanical) way to deal with the cruciferous flea is to cover the radish with white agrospan right on the seedlings. If the weather is not too hot, then the shoots under it do not stretch out and there are no fleas there. After the seedlings have grown stronger, we remove the non-woven covering material and fight further with ash.

Important note. It is desirable to transfer radishes to drip irrigation. Otherwise, all efforts to combat the flea with the help of infusion on the ashes will be in vain after the first watering on top of the leaves. The infusion is washed off the leaves, and the flea gets back to work.
Another note. If they grow next to radishes cultivated plants and weeds of the cruciferous family, then all the surroundings can be treated with chemistry.

Belyanka is another radish pest. Belyanka is white butterfly with dark wing edging. But the leaves of the radish are eaten by its caterpillars.
When dealing with whitefish, it is also desirable to do without the use of chemistry. The beds must be treated with a solution of mustard, salt and ground pepper. It is prepared like this: for a 10-liter bucket of water - 2 tablespoons of mustard, 2 tablespoons of salt and 1 teaspoon of red or black pepper.

Radish diseases

Bacteriosis. Root crops become slimy, begin to emit a smell of rot. At the same time, the leaves of the radish turn yellow.
To combat this disease, plants are treated with 1% Bordeaux liquid.

Keela. Blisters and outgrowths appear on the surface of root crops, radish leaves begin to turn yellow and wither.
To combat this fungal disease, the soil around damaged plants is watered with milk of lime. Prepare it like this: in a 10-liter bucket of water, dissolve 2 cups of fluffy lime. One plant must be watered with 1 liter of solution.

Blackleg. Young radish plants can be affected by blackleg. The leaves curl and turn yellow, blackening appears at the base of the plant stem.
To combat the black leg, prepare the following solution: dissolve 1 tablespoon in a 10-liter bucket of water blue vitriol and 40-50 grams of laundry soap shavings. Then the diseased plants are sprayed.
It is also very good to spray seedlings with tincture of onion peel(approximately 20 g per liter, leave for 1 day).

When choosing varieties of radish for planting, preference should be given to resistant varieties to various diseases.
But once again we can repeat that it is better to take precautionary measures. And then the probability of diseases will decrease sharply.

It helps well in the fight against diseases the observance of crop rotation in the garden. Since radish is an early ripening crop (harvest can be obtained in about 1 month), there is a temptation to return to the same bed with re-sowing after some time in the same season. Doing so is highly undesirable. Since it can lead to outbreaks of various diseases. It is also highly undesirable to plant radishes after cabbage or other cruciferous plants.

It is also very good to spray the seedlings with onion peel tincture 2-3 times with an interval of 6 days (about 20 g per liter, leave for 1 day).

Although radishes do not have many pests, and their ripening period is so short that they do not really have time to harm, nevertheless, sometimes the crop is spoiled. To prevent this from happening again, you need to know how to protect and how to spray radishes from pests. We'll talk about this.

How to deal with radish pests?

main pest radish - cruciferous flea. This tiny, dark-colored beetle jumps deftly and, despite its miniature size, can cause significant negative results for radishes. Fleas eat the leaves of the plant, leaving holes in them. And when they reach a certain size, the radish stops growing.

Naturally, the root crop does not ripen and sometimes even dies. It is necessary to pay attention to this pest already at the germination stage, since young plants are not able to resist the pest invasion for a long time. Cruciferous fleas are especially active in dry and hot weather.

So, how to process radishes from these small pests:

You can spray the radish leaves with a solution of wood ash (2 cups of fresh ash per bucket of water with the addition of 50 g of laundry soap).
You can not dilute the ash in water, but simply sprinkle it on the garden bed so that it gets on the leaves. The same can be done with tobacco dust.
For greater efficiency, young shoots can be treated with the Inta-Vir insecticide. Spraying neighboring cultivated plants will not interfere either. However, this should be done only as a last resort, since there is a risk of destruction of crops.

Tip: after processing the radish, it should be watered very carefully, best of all - by drip, so as not to wash off the applied control agents from the leaves.

Another enemy of the radish is the whitefish, or rather its larvae. It is best to deal with it without chemicals. For example, treat the beds with a solution mustard powder, salt and ground pepper.

To prepare the solution, you need to take 2 tablespoons of mustard powder and salt and 1 teaspoon of red or black ground pepper. Dilute this mixture in 10 liters of water and water the radish bed.

In addition to the fight against radish pests, it is also necessary to carry out preventive work - remove weeds on time, observe the correct crop rotation, do not be late with sowing seeds, on early stages apply light covering material, water in a timely manner, loosen the plants to accelerate their growth.

Radish pests: main types and methods of control

In our latitudes, a variety of pests are common, causing a lot of trouble for summer residents. Let's look at those that are most often found in Russian gardens.

Cabbage whites and their caterpillars. adult insect- This is a large white butterfly with a characteristic black border around the edges of the wings. Caterpillars have a greenish-yellow color, with black spots. At first, pests live on the underside of the leaves, gradually spreading to neighboring plants.

Cruciferous flea. This insect represents serious danger for seedlings of radishes, feeding on their leaves, making many holes in them.

The cabbage moth is a gray-brown pest with a characteristic dark fringe on its wings. Insect larvae are especially dangerous for radishes.

Cabbage fly (spring). An ash gray fly that poses a threat to radishes in the larval stage. Each larva looks like a small whitish worm, reaching a length of 8 mm. Actively developing larvae damage the root of the plant, which quickly dies as a result of their vital activity.

The summer cabbage fly differs from the spring one in an exceptionally more impressive size. Otherwise, these pests are almost identical in terms of their severity.

Garden owl. This moth, being an adult, is not dangerous for radish seedlings. The main threat is not adult insects, but their larvae. Pests feed on young radish foliage, gradually eating them from the underside and leaving only a thin skeleton. And we all know that with a critical decrease in the deciduous apparatus, the plant stops developing.

Stem nematode. Both adult pests and their larvae feed on plant sap, gradually leading to its drying out and death.

Wireworm. This enemy is able to eat almost the entire radish sprout. He likes all, without exception, parts of the plant: from the root or root crop to young greenery.

The cabbage scoop is another butterfly that is also dangerous in the larval stage. Adult butterflies of a gray-brown color, as well as garden scoops, do not pose a danger to the beds, unlike their larvae, which live by eating leaves. vegetable crops.

Pest Control Methods

Of course, the list of pests waiting for the first shoots in your beds inspires a number of fears, if not to say - inspires despair. But do not get upset ahead of time: modern Agriculture and agricultural technology have a number of tools that can, if not completely eradicate the problem of insects in the garden, then greatly facilitate the process of dealing with them.

Despite the daunting list possible pests, as well as possible negative results of the life of such insects, the fight against them, as a rule, occurs using the same means.

Most threats recede if you use a magical, proven remedy in the garden, consisting of two glasses of wood ash, 50 grams of laundry soap and 10 liters of water. Such a drug is considered especially effective if there is a fight against cruciferous flea.

good results allows you to achieve regular pollination of seedlings wood ash or tobacco dust (the method is especially effective if you resort to it immediately after watering or rain).

Mustard-pepper infusion has also proven itself well: in 10 liters of water you need to add 1 teaspoon of ground pepper (red or black) and 2 tablespoons of table salt and mustard powder. Such a tool is mainly used to lime the white caterpillar.

There is one more, several non-standard way control of insects, in particular fleas: this is the so-called sticky trap. As the main means, a thick sheet of cardboard or paper is used, richly greased with starch paste. Armed with such a device, you need to go around the entire bed, holding a sheet of paper (greased side down) close to the surface of the soil. Insects bounce and remain on paper, bogged down in a sticky paste. For several walks along the beds in this way, you can organize the treatment of plantings and get rid of almost all fleas.

Of course, besides insects, there are other dangers that lie in wait for your beds, for example, radish diseases. But this is a completely different story, which we will discuss in detail in the next article.

How to deal with radish pests

Hello dear readers!

With pests cruciferous crops(to the family of which the radish belongs) and measures to combat them, we have already met in the article "Pests of cabbage and measures to combat them." The “portraits” of these pests are described in detail in this article, but the protection of radishes and other close relatives (turnips, radishes, daikon, rutabaga, turnips) should be told separately from them, since this culture is very early and methods of pest control specific ones should be applied. Precocity dictates the use of only means that are safe for human health to control radish pests. Usage chemicals plant protection should be excluded when growing it.

First, I will list the main radish pests that most annoy this early ripening crop and us gardeners: cruciferous fleas, cabbage aphids, cabbage fly and slugs.

Radishes are cold-resistant and winter or the earliest spring timeline planting it will help us to grow the crop before the main radish pests appear. Advance preparation of the soil for growing radishes, its autumn digging with the turnover of the reservoir will ensure the partial death of pests from the cold. Keeping radish beds moist and weed free is effective. preventive measure. Growing radishes on fertile, humus-rich soil, timely top dressing, not exceeding the recommended norms organic fertilizers, strict adherence to cultivation technology will ensure the rapid growth of plants and thus avoid damage by pests in the early stages.

First, carefully inspect the surroundings of the garden with radishes, whether wild radish, colza and other cruciferous weeds grow nearby, on which cruciferous fleas settle first, and with the advent of radish seedlings, they move to them. Removing these weeds from the garden will greatly reduce the number of cruciferous flea.

You can use the recommendations common on the network and block access to the pest by covering the bed with a covering nonwoven fabric. But cruciferous fleas overwinter in the soil and this method can only reduce the number of the pest. For these purposes, it is better to use the thinnest covering material, grade 17. Thicker grades of covering material can cause overheating of plants in warm weather and contribute to the growth of the vegetative mass of leaves to the detriment of root formation.

For dusting plants after rains or watering with sifted ash, a gauze bag is suitable, after filling it, shake it over the plants. You can carry out such dusting early in the morning, until the dew has dried.

The use of self-made sticky traps to exterminate cruciferous fleas has proven itself well. Take a thick sheet of cardboard, spread with starch or flour paste. At noon, when the fleas are very active, walk along the bed, holding the plastered sheets with glue down. Cruciferous fleas, constantly bouncing, are sure to stick to such a trap. So in a few passes you can clean the entire garden, and in order to consolidate the achieved result, walking with such glue traps must be repeated 5-6 days later.

Measures to combat the cabbage fly

Since most gardeners grow radishes in spring period, the danger is the spring cabbage fly, flying out during the cherry blossom period. In the fight against this pest of radishes, it is important to strictly observe the requirements of crop rotation and grow radishes in the most early dates.

If there are signs of the appearance of a cabbage fly on plants, tobacco dust should be poured close to the stems, mixing it with ash or slaked lime.

Gardeners appreciate radishes for tasty and healthy root crops that they look forward to. However, in some cases, the harvest can significantly and a short time spoil the pests called cruciferous flea. These little bugs bring a lot of trouble. How to save seedlings and get rid of insects, we'll talk in this article.

What is this pest?

The cruciferous flea damages mainly plants of the cruciferous family, which is why it got its name. The flea has hind legs, on which it jumps like a flea, but it is not a blood-sucking insect. The bug prefers to settle on such weeds as wild radish, shepherd's purse, from horticultural crops especially fond of turnips and cabbage. However, radish remains a favorite delicacy in the early stages of the pest.

The insect has very small dimensions, the length of its oval oblong body is up to 3 millimeters. At the same time, the flea can fly. There are several varieties of the pest, among them are black, blue, light-footed and others. The differences are determined for the most part by the color of the elytra.

Beetles live in the European part of Russia, excluding the regions of the Far North. The harm from the insect is expressed in the fact that it damages the leaves, in which it gnaws out peculiar pits. The flea is especially dangerous for young greenery, as it can gnaw through tender leaves. Thin roots of crops serve as a delicacy for larvae. Pests are most active during the day, except for the period from 13 to 16 hours, when the sun is especially scorching.

AT winter period an adult flea hides in the remains of plants, crevices of greenhouses, soil. When spring comes and the ground thaws, the insects come out and begin to actively seek food for themselves, after which eggs are laid. The cruciferous flea larvae live in the soil for about 3 weeks, after this time they pupate, and new young individuals come to the surface. An insect can give birth in a whole summer period up to 3 generations.

Prevention measures

It is easier to prevent any problem than to deal with its consequences later. Therefore, experts and seasoned gardeners recommend several prevention methods that will help protect radishes. Consider. what needs to be done to protect the plantings from the pest at the initial stage.

The proximity of coriander, dill and garlic repels the pest, as the insect really does not like the smell of these plants. In the case when radishes are planted towards the end of the season, it is recommended to place the beds next to calendula or marigolds, which the flea also does not tolerate.

Fighting methods

In order to get rid of the cruciferous flea, you need to make sure that the crop is harmed by an insect of this particular species. This is not so difficult to do, because despite the small size of the pest, it can be easily detected visually. The bugs jump on the leaves, which have gnawed holes.

The main danger of a flea is that in the absence of a fight against it, the gardener can completely lose seedlings. Since radishes often appear earlier than other sprouts, it is on it that the main blow of the bugs that become active after hibernation falls. In addition, a large number of these insects can harm adult plants, as well as even hardened radish seedlings, so protection measures should be started as early as possible.

Start with prevention and deterrence, chemicals are used as a last resort.

Folk remedies

Not all gardeners accept the use of chemicals. In some cases, folk methods are quite effective, however, when applying them, it must be borne in mind that in this case it is not enough to process the crops once or twice, systematic care will be required, which, accordingly, involves a large investment of time. There are some of the most common folk methods, whose excellent action is confirmed by a huge number of examples:

humid environment;
dry pollination;
cover with non-woven material;
setting traps;
spraying infusions.

Let's take a closer look at these methods.

Wet environment

The red-colored flea thrives in hot and dry weather, but it does not like humidity. Therefore, when planting, it is recommended to choose the most humid part of the garden. Abundant watering will also scare away the pest. At the same time, do not forget that he is afraid of strong odors, so it would be useful to add strong-smelling products to the water.

dry pollination

Plantings can be pollinated various means, since the bug chooses the cleanest leaves for food. This method is very popular among gardeners, as it does not require large financial costs and is very effective. Mixtures can be different, the most commonly used is ash in combination with tobacco or road dust, as well as fluffy lime.

The components should be taken in equal proportions and mixed thoroughly. The procedure itself is recommended to be carried out early in the morning so that the composition lies on the dew, and you also need to water the radish first. In humid conditions, the particles of the mixture adhere well to wet leaves. For the most effective and uniform result, the composition is placed in a gauze bag, after which it is gently shaken over the sprouts. This method is also called powdering.

Minus this method in that it does not work with a single use. good protection can only be ensured if dusting is carried out systematically.

The ideal option would be when the gardener can carry it out after each watering or rain. And also, to achieve the maximum effect, crops should be processed not only from above, but also from below.

Shelter with non-woven material

If the crops are covered with a cloth, they will be protected not only from insects, but also from weeds and cold weather. The material must be chosen wisely, it must pass light, water and air, but at the same time be an insurmountable obstacle to pests. Well suited, for example, lutrasil or spanbond.

In addition, many recommend dusting radishes before shelter, which will serve additional protection. When under such a canvas, the radish will grow, get stronger, the leaves will coarsen a little, so when the shelter is removed, it will no longer be an easily accessible and especially attractive delicacy for a flea.

Traps

The use of a sticky flag is often used to help get rid of the pest. The procedure is quite simple and does not require special skills.

To make a flag, a piece of fabric is attached to a stick and treated with some kind of adhesive. Solidol is excellent for this purpose. After that, you need to go along the beds with radishes, slightly touching the flag with its leaves. This will disturb the insects, which will try to hide from danger, and, flying away or jumping, will touch the material and stick to it.

Gardeners advise to carry out this procedure in the middle of a dry and hot day, while repeating it several times, maintaining short time intervals. Such catching fleas will help to significantly reduce the number of insects in the beds.

Another trap is made using used engine oil, in which a piece of cloth is wetted. Boards are laid out along the beds with radishes, on which the impregnated fabric is laid. To as much as possible more insects trapped, the material needs to be turned over a couple of times a day.
