Shchitovka on dratsena - what to do

Considering the disease dracaena, it is worth mentioning the parasites. For example, schitovka. These insects infect indoor plants such as dracaena.

The scale insects belong to the Equaloptera family. They are easily recognizable by the rounded calf, while in the female of the scytum the back is covered with a wax shield.

The adult female covers the eggs while sitting on the plant, and the males “guard” the family. The larvae of the scytology are mobile, but after they are attached to the dracenum, they do not move at all and become covered with a wax shield.

Dangerous shchitovki so that adults and larvae suck the juice from the plant. On the ground damage appear yellow or brown spots. The leaves gradually turn yellow, and the stems develop incorrectly. The growth of dracaena stops, the plant dries out and dies.

  2. The parts of the plant damaged by the shield should be destroyed, as they will not develop normally.
  3. Before treatment with kerosene or alcohol, it is best to check the reaction of the plant to the substance. If it responded normally, you can carry out the procedure. It is best to do this in cloudy weather, as the leaves may burn from the sun.

Fourth. You can use garlic, onion or pepper infusions. Especially proved to be an infusion of pepper. To do this, use fresh hot pepper, which in the amount of 50 g is boiled in 500 ml of water.
