Pests not only spoil the aesthetic appearance of succulent leaves, but also prevent the plant from developing. The appearance of holes on the cabbage leaf may be to blame:

  • cruciferous fleas;
  • cabbage white larvae;
  • caterpillars of cabbage scoops;

  • slugs;
  • crucifer bugs;
  • aphid.

Symptoms

If the cabbage leaves resemble a "sieve" - ​​this is an occasion to carefully inspect the plantings and find insect pests. Symptoms of the lesion appear gradually. It all starts with the appearance of several holes on the outer sheets. If the gardener carefully monitors the plants, he will be able to take measures and begin treatment in a timely manner.

Advice!

In order not to miss the attack of parasites and not to lose crops, you should look at the plants weekly.

Treatment

If parasites are not detected in time, you can lose the entire crop. The main thing is to start the fight when you find the first hole on the sheet.

Folk recipes

Most often, ash, wormwood and potato tops are used. Recipe Options:

  • infusion of wood ash (a glass of 10 liters of warm water) - a means to insist 6 hours, then spray on the planting;
  • infusion of blooming wormwood (250 g of grass per 10 liters of warm water) - insist 10 hours, spray on cabbage;
  • pollinate with a sugar solution (200 g per 10 l of water) - the sweetness attracts wasps and ants that feed on slugs and caterpillars;
  • from cruciferous midges helps a weak solution of vinegar (50 ml of essence per 10 liters of water) - process superficially in dry weather;
  • a solution of soda repels caterpillars and other parasites.
Important!

Folk remedies do not harm the plant, but make it unsuitable for eating by parasites.

Chemicals

Dressing cabbage

Purchased drugs are most effective in controlling insects. They are safe for humans if the instructions are followed. Popular remedies:

  • Diazinon;
  • Dimilin;
  • Fox
  • Ratibor;
  • Actara 240cs, etc.

Treatment with insecticides is carried out several times, as the larvae hatch gradually.

Advice!

When working with chemicals, personal protective equipment is used.

Mechanical Pest Management

Some gardeners collect larvae, caterpillars and slugs by hand. This method is ineffective, because plants attack new pests and they will have to be removed constantly. Collect insects better in the morning.

From butterflies, you can use special nets. They let in air and sunlight, but do not allow insects to come into contact with a head of cabbage.

Good results can be achieved by using traps with syrup or beer. A liquid with an attractive aroma is poured into a low container and placed on a bed. For 1 square. m. of soil should be at least two traps.

Prevention

Cabbage

In order to avoid the attack of pests, experts advise using the right neighborhood. Cabbage beds are located next to tomatoes, basil, mint or onions. The pungent smell of plants repels insects. Other preventative measures are also effective:

  • crop rotation: do not plant cabbage on the same bed every year;
  • frequent weeding - the top layer of the soil is disturbed with nests and insect passages dug in it;
  • moderate watering;
  • harvesting should be completed by cleaning the beds from all residues and digging.
Advice!

It is especially important to weed blooming weeds, as they attract butterflies.

Another way to prevent the appearance of holes on the leaves is to plant seedlings early on the bed. In this case, the head of cabbage will be set before pests become active and it will be more difficult for them to attack the plant.

Advice

Slug eating

 

The insect that leaves the holes can be identified by their size. Small holes gnaw through caterpillars, and large holes slugs. It’s easier to deal with caterpillars, and slugs will have to be collected manually, and then regularly sprayed.

As a preventive measure, the row-spacing of cabbage plantings is sprinkled with stepsons of tomatoes.

Some gardeners use infusion of laundry soap to prevent and control parasites. They are sprayed with plantings in dry and calm weather.

After the rain, it is necessary to collect all the slugs - they crawl to the surface with high humidity.

Reviews

Svetlana, St. Petersburg

It's a shame when you put a lot of effort into the garden, and plants spoil the pests. Most of all I like to use beer traps. Spraying is almost useless if it rains. And I basically do not use chemistry (then I myself eat these vegetables!). But, of course, you need to pay attention to your plantings and notice insects on time, otherwise the crop can not be saved.

Last year, I ran into holes in the cabbage. On the advice of a neighbor, he sprinkled all the plants with ash through a fine sieve. It helped me - after a few days I examined the heads of cabbage and did not find a single pest.

Holes on cabbage leaves appear quite often. Preventive measures and timely treatment from insects help keep the heads healthy.
