What are Gauls, where are they common

Galls are globular formations on leaves that result from insect bites. Harmful to agriculture, but are actively used in traditional medicine. The article will tell you about the features of education, the principles of their use and methods of struggle.

Spherical growths on leaves with a diameter of one and a half to two centimeters are widespread. These are abnormal cell growths on leaves, shoots and even plant roots.

Most often found on oak leaves. In Mesopotamia and Asia Minor, the so-called "gall" oak is widespread. Neoplasms on its leaves are actively used in medicine.

These globular outgrowths on oak leaves are formed as a result of the laying of eggs by the oaky walnut.

Currently, galls are ubiquitous and can infect any deciduous plant. Even indoor flowers are not out of danger.

The mechanism of formation of galls

The process of formation of growths resembles the process of the spread of inflammatory processes in the human body.

In addition, the education mechanism has its own characteristics:

  • A gall is formed at the site of damage (insect bite);
  • An overgrowth can form not only on the leaves, but also on all other parts of the plant;
  • The size of the galls can vary: from a few centimeters to huge growths.

There are several types of insects, the bites of which can provoke development, the most common are gall mites:

  • They belong to the superfamily of arachnids and the order of acarimorphic ticks;
  • They have small body sizes: from 0.1 to 0.6 mm;
  • No sense of smell;
  • Biting the plant, they feed on it, destroying the tissue structure of the leaf.

In some cases, the formation of galls is due not only to the presence of a bite. So, for example, a female nutcracker lays a larva in an oak leaf bud, which carries out a cycle of transformation into an adult there. As a result of this, an outgrowth is formed on the leaf, surrounding the larva - gall.

Location features:

  • Galls on pear leaves are arranged in rows, parallel to the central vein of the leaf;
  • On leaves, apple trees are located throughout the leaf. There are especially many of them on the underside;
  • Galls on willow leaves are represented by chains of convex growths on both sides of the leaf.

Do not underestimate the harm of a gall mite. Affected leaves do not go through the full growing season, but dry up and fall off prematurely.

In addition, the gall mite can infect not only leaves, but also young shoots, buds, which negatively affects the level of plant productivity.

How galls are used in medicine, what is made of them

The collection of Gauls takes place in the last summer month. Harmful to plants, they are widespread in folk medicine.

So, for example:

  • Gallic tincture is used for mouthwash with flux. Also, it is used to treat frostbite parts of the body;
  • Tincture mixed with vinegar is used to treat diseases of ENT organs;
  • It is known to have an activating effect on the hair growth process;
  • Helps accelerate the healing of cracks on the lips, burns;
  • They are also used for the treatment of eye ulcers (both for external and internal use);
  • Used to strengthen the organs of the digestive system;
  • Internally take infusions for the treatment of diarrhea;
  • Used as an adjuvant in the treatment of tuberculosis;
  • Lotions and rubbing from the infusion of galls are used to treat various diseases of the epidermis: insect bites, lichens, ulcers;
  • Help in the treatment of leucorrhoea.

Brewed dried galls are taken internally.

For lotions, use a decoction from:

  • One glass gall
  • Liters of boiled water

The mixture is boiled for five minutes, after which the broth should settle and it is filtered.

Galls on leaves are widely known in folk medicine. Tinctures of these formations are used both internally and externally.

What methods of dealing with galls are used

The best way to deal with galls is to prevent plant growth. Treatment of a plant damaged by a gall mite is much more difficult, because it is impossible to restore a damaged leaf. However, if you do nothing, the entire plant may die.

For the treatment of damaged plants, the following are used:

  • Systemic acaricides;
  • Treatment of plants with ten percent karbofos at the rate of 75-90 g per 10 liters of liquid or with twenty percent keltan at the rate of 20 g per 10 liters;
  • Pyrethroid insecticides;
  • Spraying plants with a mixture of colloidal sulfur at the rate of 100 g per 10 liters (done after the plant has faded and again in the middle of summer);
  • Final burning of fallen diseased leaves.

It is also important to remember that many insects have the ability to adapt to the effects of poisons. This should be taken into account when selecting preparations for processing plants, since an incorrectly selected poison can provoke an intensification of the development of the gall mite population.

Leaf galls are rounded formations that result from insect bites. Dangerous to plants, Gauls are widely used in folk medicine. However, it is worth remembering that ignoring the gall mite problem can lead to the death of the plant.
