How to bring out thrips in chrysanthemum

Any kind of chrysanthemum from thrips freed with insecticide solution, eg, B2 or by milder means (they are guided by the degree of damage to the bush).

In the early stages of the disease and for the purpose of prevention, alternative methods can be used.

How to fight on violets

Thrips often grow on violets. Violets can be treated with insecticidal hot tub in an aqueous solution of phytopharm and anti-flea shampoo (8 liters X ampoule X 25-30 ml, respectively) and one-time pouring with actara solutionprepared strictly according to the instructions.

Such ablution is preferable to spraying, since by immersing the entire bush in the liquid, we do not leave a single untreated area of ​​the bush to the parasitic insects.

Nuances of the procedure:

  1. before immersion in a warm solution, it is imperative to remove the air foam from its surface (otherwise it will dry out on the leaves, and they will be "decorated" with unattractive spots);
  2. in front of the "font" each bush is sent to the shower, which will wash away the dust layer on the foliage;
  3. before all water procedures, the soil of the flowerpot is covered with a plastic bag / piece of film;
  4. treated violets cannot be immediately placed under the lamps (you must wait for the moisture to evaporate from the surface of the bushes).

How to remove from orchids

Thrips on orchids are removed:

  • manually;
  • wiping with a cloth soaked in soapy water (after a while, be sure to repeat the procedure, replacing the cloth wetting solution with clean water);
  • spraying with a ready-made or purchased insecticide (after treatment, the bushes must be kept in partial shade for at least 14 days);
  • a repeated course of the same therapy, replaced or combined.

Preventive measures against thrips on orchids:

  • special soil sticks made from a mixture of fertilizer and substances that make the taste of plants less attractive to sucking insects;
  • systematic thorough examinations of the bushes;
  • systematic spraying of plants with warm water (thrips do not like a humid environment);
