Each grower needs to know which diseases and pests affect orchids, as well as how to deal with them. Any pests eat the juice of the flower and with active reproduction are able to completely bring the plant to a very poor state.

Of the orchids, phalaenopsis is most often cultivated at home, and gardeners have to carefully study information about combating their diseases and pests.

General information

Most often, phalaenopsis is affected by such types of pests as spider mites, mealybugs, aphids, scale insects, and thrips.

Among the most common diseases of phalaenopsis and other orchids, it should be noted bacterial leaf spot, powdery mildew, sooty black fungi, and rot. It should be remembered that most often diseases are the result of adverse conditions of their maintenance, as well as improper care.

Only knowing how to deal with diseases and pests of orchids, you can develop an effective protection scheme.

Mealybug on orchids

Such a pest as a mealybug resembles a small fluffy, quite elongated lump of white with long antennae. For all types of phalaenopsis, the mealybug is a significant danger. The reason for this is the rather high complexity of detecting this pest.

As a rule, the mealybug hides very deep in the joints of the leaves of the plant. Often he hides on the bottom of the orchid, near the base or in the basal part of the plant. The worm sucks all the juices from the indoor flower and secretes a mealy liquid. Usually the pest becomes noticeable at the stage of almost complete death of the plant. In 100% of cases, you can see lifeless, yellowing and drying leaves.

Standard pest control measures include the following procedures:

  • cleaning plants from dry roots and leaves;
  • regular inspection of all places where a worm can hide, followed by manual collection of detected insects;
  • daily pest checks;
  • treatment of affected plants with a solution of water with laundry soap;
  • treatment of substrates with Fitoverm.

Aphids on orchids

The pests themselves are not very scary for strong adult plants, but the excrement secreted by them, which cover the leaves with a very sticky mass, does not allow the flower to fully breathe. In addition, aphid isolation is an excellent medium for the reproduction and development of various pathogenic fungi and bacteria.

Standard control measures for this pest are as follows:

  • washing the leaves and stems of the plant with water and chopped laundry soap;
  • processing the plant and substrate with a solution Fitoverm in accordance with the instructions supplied by the manufacturer of the drug.

The faster the aphid is found on the plant and the protective measures are taken, the more likely it is to restore the orchid's health and flowering appearance.

Orchid shield

The scale insects family is numerous, and orchids are most often affected by such representatives as a false scutellum and scutellum. It is not difficult to detect a false shield on a plant. The scabbard forms characteristic tubercles on the stem part or leaves. These tubercles at first glance are not very noticeable and look like part of the plant itself. The color of such areas can be from brownish to yellow.

The pest insect at the larval stage moves throughout the plant and sucks the juice from the stem part with its proboscis. After some time, the larva is covered with a light brown shield. Both adults and insects at the larval stage use the nutrients of the flower.

As a result of life activity, the scabbard leaves a sticky viscous liquid on the plants, which is the optimal medium for the propagation of diseases such as rot and fungus.

Standard methods for pest control involve the following activities:

  • flushing the affected plant;
  • manual removal of remaining insects;
  • treatment of orchids and substrate with a special solution based on "Fitoverma" or "Actellika";
  • re-spraying "Fitoverm" or "Actellicus" after seven or ten days;
  • transplanting the plant into a new and clean planting substrate.

Spider mite

Spider mites pose a serious danger to indoor orchids. They are very common orchid pests. As a rule, plants can be hit by a tick in the greenhouse or after purchase, already at home.

Regardless of the type of tick, the lesion caused by the flower is identical. They inflict punctures on the leaves of the plant, which can be seen as dots. As a result of the defeat, the leaves first acquire a white hue, and then completely discolor and then dry. The buds after being hit by a tick do not open and fall off. One can observe the presence of a barely noticeable cobweb on the leaves.

Standard pest control measures should be implemented as quickly as possible and include:

  • manual collection of ticks from the plant, followed by thorough washing of the flowerpot and the place where the flower pot stood;
  • installing a flower pot with an orchid in a low container filled with water;
  • spraying the plant and planting substrate with the Fitoverma solution, which is diluted according to the attached instructions, with repeated treatment after seven days.

We also recommend that you familiarize yourself with the material of the article, which deals with the main diseases of Phalaenopsis orchids and effective methods for their treatment.

Nematodes on orchids

Externally, the nematodes are small white worms. They penetrate the stem part and the root system of the indoor flower. Sucking plant juices, the pest poisons phalaenopsis with waste products. Affected orchids can stop growing and then rot and die. To get rid of the nematode, it is recommended to spill the substrate with drugs Dekaris or Levimisil.

Orchids: Pest Control

In addition to the fact that the orchid itself requires attention and careful care, it should be protected from various pests and diseases. In order for the plant to remain healthy, it is necessary to know the symptoms of diseases and insect damage and take timely measures to eliminate them.
