Diseases and pests of hoyi in the photo

This kind of flower, like other houseplants, is prone to various diseases. They are provoked by pests or improper conditions of wax ivy.

If the plant is in warm and humid conditions, then it is at great risk of "catching" fungal diseases. But even dry air does not guarantee its protection from insect pests.

When hoya is affected by phytopathogenic fungi, its growth stops. The leaves begin to fade and turn yellow. These pathogens provoke the development of powdery mildew and other similar diseases, manifested in the form of a touch of white, light gray or black. It is easy to wash hands.

The main diseases of hoyi caused by fungi are:

  1. Powdery mildew develops at very high humidity. It covers the leaves of the wax ivy with a light coating and spreads rapidly throughout the plant. Therefore, it is important to remove all dying leaves and branches in time.
  2. The black fungus settles on insect secretions. It covers the leaves with leaves and does not allow them to breathe.
  3. Rust is manifested in the form of spots and edges of orange or red color on the leaves of hoya.

The main control measures are plant transplantation into new soil, removal of affected parts and treatment with fungicides, Topaz, Bordeaux fluid, sulfur or copper compounds.

The main causes of rot

It provokes:

Excess water in an earthen coma is the most common cause. It leads to the rotting of the roots or other parts of the plant, and then to the death of the entire flower. In the lesions there is a softening of the tissues, they turn into a liquid with an unpleasant odor.

When root rot comes, the situation is more insidious. At the beginning of the disease, the plant behaves as if it lacks water. But additional watering only aggravates the situation. To save the wax ivy from rot, all affected parts must be removed by treating the cut points with activated charcoal. If the disease has settled on the roots, then only cuttings will help.

Bacterial infections and insects

Pathogenic bacteria cause the flower to wilt, which begins with its apex, and then spreads to the entire plant. Another characteristic feature is the appearance of spots on the leaves. They spread rapidly over the entire surface of the plate, causing it to turn yellow and wilting. Measures to combat bacterial infections are the content of culture in dry air for the period of treatment and treatment with copper preparations.

Wax ivy is affected by such pests:

.
  1. Nematodes are colorless worms up to one centimeter in size. They often settle on roots, as a result of which they do not give the plant nutrients. Affected by nematodes, hoya turns yellow, discards leaves, stops growing.
  2. A spider mite settles on the underside of the deciduous plates of wax ivy. In their sinuses a web is formed, and the leaves themselves are covered with spots. Spider mites do not like water, so when it appears you need to spray the flower as often as possible.
  3. The shield is similar to small bumps covered with a layer of wax. It feeds on the juice of the plant, causing it to dry out. Leaves of wax ivy first turn yellow, and then turn brown. The amazed flower dies with time.
  4. The chervets can reach up to 5 mm in size. It attaches to the leaves, emits sticky drops on which the sooty fungus settles with pleasure. Thus, the plant receives a "double blow does not allow new shoots and dies.
  5. Podura differs from other pests in that she can jump. This white winged insect develops with a significant overmoisture of the earth coma. It affects only the ground part of the hoya.
  6. The whitefly looks like a small moth. Its larvae actively feed on the juice of the plant, located at the bottom of the leaf. The culture is covered with small spots.

All pests cause the fall of the hoya leaves, stop its growth. The weakened plant quickly dies if no measures are taken to destroy the insects. When nematodes are found, wax ivy is necessarily transplanted into a new, disinfected land. In all cases, one of the preparations is treated according to the instructions: Aktofit, Aktara, Confidor-maxi, Sanmayt, Appolo and others. As a rule, they are watered and sprinkled twice with a short break.

How to save a plant from drying out

There is no need to water hoyu often, she does not like it. In this case, the flower categorically does not tolerate irrigation with cold water. In the summer it is watered more often, not forgetting about regular spraying. If the wax ivy began to dry up, then it is necessary to adjust the watering and bathing the plants. For this, a non-flowering specimen is immersed in water for 40 minutes. Also it is necessary to cut off several cuttings and put them on rooting.

Blooming wax ivy is strictly forbidden to bathe.

Assistants for the resuscitation of hoyi are Zircon and Epin preparations. The first restores the root system, and the second - saves the ground part (trunk and leaves). With a solution of Epin, the flower is sprayed, avoiding the sun rays from hoyu. If you use several funds at the same time, then within 10 days you can save even a much ruined flower.

What if the leaves turn black?

Many do not know why the leaves turn black in ivy and how to treat them? Often the discoloration of the plates causes pathogenic bacteria. They infect the plant through wounds or cuts and spread throughout his body. In this case, wax ivy withered branches, on the trunk ulcers are formed.

One of the reasons that hoya does not bloom is the inappropriate air temperature in the room.

To save the ivy from drying out:

  • isolate the plant;
  • Carry out pruning of affected segments;
  • treat with copper-based drugs;

If these measures failed to save the wax ivy, then it is destroyed. Since another cause of black foliage may be a viral disease, which is almost not treatable.

Why yellow hoyi leaves?

This flower does not like extreme conditions: heat or cold. At low temperatures in the room, the hoyi begins to yellow leaves, it slows down growth. Change in the color of the plates occurs with sunburn.

Yellowed leaves must be removed. They will not restore their tone, but they can become a place of development of pathogens of various diseases. For a plant, it is important to choose a room with optimal lighting or to cover the window with a grid. Another reason for changing the color of the leaves may be rot, as well as damage by insects.

If the hoyi yellow leaves and falls, then the cause may be excess sun.

Falling of deciduous plates can provoke various factors:

  • Moisture overmoisture;
  • rearrangement of the plant to another place;
  • Cooling, especially in the winter due to ventilation.

If the houyas have yellowed leaves and you do not know what to do, then the first thing you should resort to is to move the pot from the cold room. Water should be water at room temperature or slightly warm. If there is not a single sheet left on the plant, this is not the reason to throw it away. You can trim the wax ivy at a height of about 5 cm from the ground and wait for new shoots.

Knowing what are the diseases of hoyi and how to determine them, you can grow a healthy and incredible beautiful plant. The correct watering and the corresponding temperature of the air in the room is a pledge of abundant flowering.
