We fight the cruciferous flea

Cruciferous flea is a small black or golden bug that can greatly harm young seedlings of almost all cultures.

A pair of such insects in 1 day eats up a bush of cabbage or tomatoes (3-5 leaves) to the veins, gnaws the “hearts” from the beet seedlings, and does not disdain young horseradish leaves.

How to fight

Fleas attack the garden in dry and hot weather at the beginning – mid-May, when the planting season begins. Bugs are sensitive to high humidity and almost never appear in rainy seasons. You need to deal with them with simple watering. If you water the ridges in a timely manner, abundantly wetting the foliage of seedlings or seedlings, the soil around them, then the risk of pest attacks is reduced. They will find fodder plants in the drier corners of the garden.

It will be possible to protect seedlings with the help of covering material. If it is not possible to keep the ridges wet, cover them with lutrasil or another non-woven fabric. Modern membranes allow light, air and moisture to pass through, but for fleas they will create an insurmountable barrier. It is important to carefully close all openings near the soil (sprinkle the edges of the fabric).

Cruciferous crops (radishes, cabbage, daikon, etc.) that are attractive to pests should be planted and sown a little later than the traditional dates or earlier if the plants are cold-resistant. Fleas appear at an air temperature of + 15 ° C, and by the middle – end of June they lose activity and switch to eating grown weeds.

Other methods

In addition to agrotechnical methods of combating leaf-eating insects, gardeners use many methods to scare away pests from the garden.

At home, you can use simple folk remedies for cruciferous fleas:

  1. Dry pollination of foliage. As pollination materials, ash, tobacco dust, fluffy lime, naphthalene can serve. In the latter case, the insects not only scare away, but also die. Cruciferous fleas do not gnaw at any dusty leaves. To do the job correctly, the selected materials (for example, ash and fluff 1: 1) are placed in gauze, its corners are collected to make a bag. It is shaken over crops or seedlings so that the powder evenly covers the foliage. Pollination is best done early in the morning, while the leaves are wet from dew.
  2. Infusions of aromatic herbs. All of these methods mask the smell of plants that damage fleas. For scaring away, you can use the bulbs of garlic, leaves and roots of dandelion, tobacco, wormwood, potato tops. Approximately 250 g of any raw material is ground in a meat grinder, pour 5 l of water and insist 1-2 hours. To keep the solution longer on the leaves, add 1 tbsp. l soap chips or detergent. It is necessary to spray both the upper and lower sides of the leaves.
  3. Smelling strongly. To combat fleas, not only plant extracts are used, but also solutions of household substances: tar, vinegar, ammonia. They are diluted with water at the rate of 1-2 tsp. for 1 liter After rain, the treatment will have to be repeated.
  4. Planting plant protectors. Shortly before planting seedlings, you need to sow the seeds of marigold, nasturtium (it is better to use low-growing varieties) or calendula. Plants are planted with cabbage or tomatoes.
  5. Spent engine oil. In the product, you need to moisten the pieces of matter and arrange them between the rows. When moving, insects stick to the fabric.

To prevent the appearance of a large number of fleas, it is not recommended to leave tops and other plant debris on the ridges. Digging the garden before winter will not allow the fleas to winter in the soil.
