The cruciferous black flea on the cabbage is a small insect no more than 3-4 mm long with a shiny curved back. The beetle is distinguished by good jumping ability provided by thickenings of the femoral parts hind legs.

A black cabbage flea awakens in the ground when spring heat sets in, when the average daily temperature is set at 15 ° C.

Cruciferous flea larvae develop in soil eating plant roots, in most cases weed grow nostyu. The larva turns into an adult individual in 2-4 weeks, pupating by the end of June.They can also hide from cold weather and overwinter in greenhouse designs or in piles with last year’s fallen leaves.

Signs of appearance and favorable factors

Adult small bugs that appeared on cabbage plantings young leaves and stems begin to eat, and their larvae damage the root system of plants. As a result of a massive invasion of cabbage fleas on cabbage, plantings can die in a few days.

You can determine that a black cruciferous flea appeared on the cabbage by changing the appearance of the vegetable crop:

  • under the destructive effect of the larvae in the soil on the root system of plants begins to wilt and dry even with heavy watering,
  • when adults of the cabbage flea appear, the cabbage foliage is covered with sores, gnawed between the veins, and extensive leaf gnawing.

As a result of severe damage to the cabbage seedlings, the plants dry up and die.

Among the conditions that favor the active propagation of the cabbage flea, hot sunny weather and the absence of rain.

Agricultural measures

Proper agricultural measures prevent the emergence and propagation of a cruciferous flea on cabbage.

Planting dates

By observing the timing of planting cabbage seedlings, it is possible to avoid a massive damage to the plantings by the pest.So, it is recommended to plant cabbage before and after the main stages of development of the insect. Early varieties of vegetables that are planted in early April and later varieties that are planted in July can avoid pest damage. By the time adults are ready, such plants have time to grow and take root, and their foliage is roughened, which becomes unattractive for the pest.

Weeding

Adverse conditions attract pests

Timely harvesting of weeds makes it possible to create unsuitable habitats for the pest, breeding and development conditions. Therefore, it is recommended to thoroughly clean the site of plant debris in the fall, after a harvest of vegetables.

Watering

Such a measure as abundant watering on hot days can create protection for cabbage plantings against an insect. Cruciferous flea does not like moist environments.

Phytoncide neighbors

Planting phytoncide plants, which include dill, garlic, coriander, can be measures to prevent the appearance of a pest in the beds. They create a specific odor that repels the pest.

Shelter

You can protect the cabbage plantations in the fight against the cabbage flea by using covering materials if they cover young seedlings while they are it will not finally take root and will not get stronger.Among such materials are spandbond, lutrasil and other non-woven fiber.

Folk recipes

Folk remedies are also effective methods in the fight against cabbage flea, allowing you to quickly get rid of it.

Dusting

Dusting cabbage plantings with wood ash, tobacco or road dust or red ground pepper makes them unattractive to the insect. Such components work effectively both independently of each other, and in combined mixtures.

It is recommended to dust cabbage plantings or aisles in the morning, when the dew still remains on the plants, or in the evening after watering. The protective property of such products is valid until the first rain.

Spray

Spraying with tinctures will help get rid of insects

Among the effective folk methods of combating cruciferous flea on cabbage are self-prepared infusions that are sprayed with seedlings:

  • a mixture of tomato tops and chopped garlic, taken in equal proportions and diluted with a ten-liter volume of water with the addition of a small amount of soap for binding,
  • tobacco (200g) diluted in 10 liters of water with a small amount of soap,
  • wormwood (1 kg) boiled for 20 minutes along with garlic (100g), diluted after being prepared to a volume of 10l,
  • diluted in water chicken droppings in a proportion of 1:20, fermented outdoors ,
  • vinegar (200g of table solution or 2 large spoons of essence), diluted in 10 liters of water.

The defeat of the tops is especially dangerous — the growth of the root crop stops and the plant dies.

How to determine exactly what hit the root crop — a disease or insects?

If the plant overcomes the disease, it changes its physiological state. Symptoms of various diseases can be:

  • the appearance of white oil deposits on stems, leaves, pedicels and testicles;
  • spherical growths on root vegetables, which eventually acquire a brown hue and begin to rot;
  • black, light yellow or brown spots on radish leaves;
  • root crops become covered with brown spots and overgrow with gray down;
  • the veins on the leaves or the base of the stem turn black, the leaves turn yellow and begin to fall off.

Pathogens with such manifestations are fungi and viruses.

When attacking a pest culture is usually mechanically damaged. — ulcers and holes in the leaves, holes in the roots. Also, almost always, it is possible to detect the presence of the parasitic insects themselves on any part of the plant.

Harmful insects — description, photo and methods of dealing with them

Further on the photo you can see how some plant eaters look like.

Cruciflo flea

Black bugs moving along the bed of intense jumps, making them easy to spot. The pest infects the leaves of the radish, gnawing fragments and rapidly increasing the affected area. The attacked radish stops growing and dries out.

Especially active cruciferous flea in dry hot weather.

How to deal with cruciferous flea on cabbage

The appearance of cruciferous flea on cabbage is capable of delivering a lot of trouble to both novice gardeners and hardened aces of this occupation, but it is sometimes quite difficult to get rid of it. The following text will be devoted to the struggle with the cruciferous flea, which has settled on your cabbage.

Pest description

Cruciflo flea pest, which got its name from the culture, which predominantly eats, opting for representatives of both the cultural cruciferous (cabbage, radish, colza) and weed cultures (for example, mustard and shepherd’s purse), which is a whole science to fight with.

Did you know? Parasites on cruciferous cultures are not only adult representatives of this species, but also larvae.

Larvae develop and live underground, feeding on the root system of plants. The period for which the larva turns into an adult is about 2-4 weeks.

At the end of July, the larvae pupate and caterpillars appear 6–14 days later, which then turn into mature individuals.

What is the danger?

The process of awakening of pests begins in springtime, when the average daily air temperature begins to approach + 15 ° С.

Small beetles eat up the peel of young leaves and stems of your cabbage, and their developing larvae grind the roots of plants. If there are many fleas that attacked your plant, it can die in just a few days. Even if you managed to save your landings from the already started invasion of flea beetles, the crop will lose its pleasant aesthetic appearance.

In this regard, it is recommended not to wait for the moment when the plants will be attacked by the pest, but immediately after making the landing, take a set of preventive measures, which are described below. The most dangerous are fleas for young, newly planted plants, since they still have an insufficiently well-formed vegetative mass and with a higher probability will not suffer this “attack”.

Signs of cruciferous flea on cabbage

To determine the appearance of cruciferous flea can be on the appearance of plants. First, before the period of emergence of adult individuals, it becomes noticeable that the leaves of the plant wither, even despite its abundant watering. This occurs as a result of the destructive impact of the larvae of the flea on the root.

Did you know? It is still unknown who is a wild relative of the cabbage garden, it is unclear in what place it was first grown as a cultivated plant.

Later, after the appearance of imago, ulcerous gnawing, inter-vein crevices, and even skeletonization of the leaf begin to appear on the leaves of cabbage until the state of the presence of veins alone.

Learn ways to effectively fight against rapeseed flower beetle, ants, flea beetles, cabbage, shchitovki and false guard, leafworm, spider mite, moth.

Methods of struggle

If you are sure that the cruciferous flea has settled on your cabbage, it’s time to take measures to combat its complete destruction. Modern science has developed a wide range of chemicals that can help you in the fight against this pest, but no one forbids you to use folk remedies, many of which show no less effective.

Folk methods

Grandfather’s proven methods include the following activities:

  • The easiest way to implement maintaining a stable wet environment. The effectiveness of this method is due to the fact that the flea is not able to survive in a wet environment. That is why radishes, cabbages and other cruciferous plants are recommended to be planted in wet areas of your garden.
  • Pollination of leaves with dry powders. Powder is prepared from wood ash and lime-fluff or tobacco dust in a 1: 1 ratio, and then poured into a gauze bag. You should shake this bag over the affected plants in the morning periods, before the dew comes down.
  • You can use the same method of dry pollination, but already the land between rows and using naphthalene or tobacco dust.
  • Spraying various decoctions and infusions. For example, steaming ash in boiling water in a ratio of 1: 3, after infusing for several days, add a little soap solution or, say, process 200 g of garlic and 1 cup of tomato leaflets using a food processor, then add the mixture to 10 liters of water of average temperature, after straining, add 1 spoon of liquid soap.
  • Haveseedling and seedling cover. Suitable for those who have light covering material available (lutrasil, agrospan, spanbond). Cover them with young seedlings, as a result, the midges simply do not crawl to the desired plants, while air, light and water easily overcome this barrier.
  • You can also catch flea with pieces of cloth.which are well impregnated with used automotive oil. To do this, these pieces of fabric should be placed on cardboard sheets placed along the beds. For the greatest efficiency, it is recommended to place traps at a distance of 4 m from one another.

Important! If traditional methods do not give the expected effect, do not over-tighten and proceed to chemical treatment, since every day the probability of losing the crop will only increase.

Chemicals

The best result will certainly be given by spraying your plants with insecticide solutions.

However, it should be remembered that most of these drugs are a threat to human health, so you should observe precautions when working with them. You can use any solution, for example: Aktara, Karbofos, Sherpa, Decis, Arrivo, ECD and many others.

Remember that each of these solutions has individual, different from other methods of preparation and application rates. Therefore, properly read the instructions before processing.

It is best to spray these preparations in the evening, after sunset, because during this period almost all the midges sit on the sheets.

Pest prevention on cabbage

Before you deal with cabbage flax, you can and should try to prevent its occurrence on your site. The first measure to help prevent the occurrence of a flea is to destroy the cruciferous weeds that feed on this insect in the first period after its awakening after hibernation.

Important! In the autumn, it is necessary to dig up your plot, because this insect, like many others, chooses the upper layers of soil for wintering, so after digging it turns out to be on the surface, where it quickly dies when frost occurs.

It is very important to take measures to facilitate the early maturation of young plants. timely and abundant feeding, watering, regularly conducted loosening of the soil.

It is recommended to plant cruciferous crops near phytoncides plants that produce chemicals, the smell of which drives off annoying insects.

For cruciferous crops include: dill, tomatoes, garlic, potatoes, nasturtium, cumin, coriander, calendula and marigolds.

The main thing to remember is that every day of delay increases the chances that your crop may die, so it is important not to delay the transition from traditional methods of pest control to the use of chemicals.
