Description of the pest
The scale insect is a small insect, but even at such a small size, it can harm an entire tree. The body is covered with a shell, which acts as a protection, so not everyone can recognize a living being in hard growths. Experienced experts call the pest a garden turtle, and this fully describes the appearance. A few weeks are enough for creation to destroy the plant - this applies to both outdoor and indoor specimens. The length of the insect reaches 5 mm, it sits motionlessly on the plant, so it is easy to confuse it with drops of resin.
Males are 2 mm smaller than females, they most often move with the help of wings and legs. The main danger is represented by the females, which stick to the leaves and branches, it is not so easy to deal with them, because the shell does its job perfectly. The eggs hatch into larvae, which leave behind a sticky liquid, which, in turn, is an excellent place for infection to develop.

Chemicals
Experts note that adults are not so easy to destroy, it is most difficult to fight them, since there are no appropriate drugs. Some products dissolve the insect, so this option is not suitable for processing plants that are intended for food. Most chemicals should not be used on fruit crops, as they contain poison.
Insecticides are designed to treat plants and the areas where they are found. This includes "Actellic", which is in demand for the fight against aphids, scabbard and false shield. It contains a strong substance that remains active for up to 10 days. The only drawback is the pungent smell that remains in the apartment for several days. "Aktara" is designed to protect flowerpots and garden plants, the active ingredient is thiamethoxam. This product is not afraid of sunlight and will not lose its effectiveness in dry air or rain, which is a great advantage.
However, it should be remembered that each chemical preparation belongs to a certain hazard class not only for humans, but also for bees. After spraying the crops with Aktara, it is necessary to wait about three weeks before harvesting. Phosbecid has a systemic effect, which protects garden and horticultural crops, and also easily copes with the destruction of insects. It is a highly toxic product that should not be used during flowering. "Bankol" is suitable for fighting scale insects, it can be used in hot places, moreover, it does not have a sharp aroma. It should be noted that this drug is considered one of the best, as it is suitable for the destruction of the most persistent parasites. Low toxicity is one of the advantages.
Pyrethroids include "Inta-Vir", which effectively fights scabbard and other pests.The drug must be diluted with water and treated with it, the effect may last for several weeks, depending on the type of soil. Each tool has its own characteristics. Having decided on the choice, read the instructions and follow the manufacturer's recommendations, observing the dosage exactly.
Traditional methods
The main advantage of traditional methods is that they are less dangerous to plants or humans. From onions, you can prepare gruel, which is used to process the part of the plant affected by the shield. You can remove parasites with a soft brush. At the final stage, the plant must be washed with soapy water. To prepare the tincture, the onion is crushed and infused for several hours. An infusion of fresh pepper is added there, then the agent must be left for a day, and then strain and start processing. About 20 ml of liquid soap and a teaspoon of alcohol are added per liter of water.
This option is suitable for controlling the eggs and larvae of the parasite. Experts recommend making a trial version by processing a small part of the plant and waiting for half an hour. If the plant hasn't responded, you can continue. Burdock oil and washing powder will help not only destroy pests, but also take preventive measures. A spoonful of oil and the same amount of washing powder are diluted in a liter of water, you need to insist for several hours. For work, a spray bottle is used to spray the plant.
It should be noted that such folk methods do not help with the invasion of parasites, they are effective only at an early stage.
Prevention measures
Proper care of any plant is the best prevention of attacks from any pests, not just scabbards. If trees or shrubs have sensitive foliage, special inspection is required. If you are dealing with indoor plants, then each purchased item must be held separately and examined for insects. The room needs ventilation, avoid high humidity and dust, spray the leaves to remove dust.
When it comes to open space, for example, in a garden, infestation often begins with wild plants, which means that it is important to destroy weeds, weed the soil, and remove all unnecessary things.
