Professional gardeners and amateurs do not recall phlox diseases often. The thing is that the plant is not prone to the appearance of various diseases. But if the variety is valuable, you need to know how it can get sick, and how to deal with the disease.
Phlox Viral Disease
Viral diseases are considered one of the worst. They are transmitted in different ways: with cuttings, with juice during pruning, with seeds. Moreover, if the plant has caught the virus, it can be extremely difficult to save it. The main viral ailments characteristic of phlox are indicated below.
- Leaf threading. The following symptoms are characteristic of an infected plant: fragility of shoots, slow growth, threadlike leaves, death, lack of flowering.
- Rattles. Bearers of rattle may be some types of phlox. The disease is characterized by the appearance of bright spots, which become larger with time. Plants such as asters, primroses and bulbs provoke this virus.
- Variety. Virus transmission occurs through the seeds, pollen, or sap of diseased plants. The disease leads to the fact that phlox lose their varietal qualities and become equally mottled. At the same time, light stripes appear on the flower petals.
- Rugosity. The disease is characterized by irregular leaf shapes and the appearance on them of a mosaic pattern with brown veins. Sick, the plant becomes brittle, weak and dies quickly.
- Necrotic spotting. Appears due to the cucumber mosaic virus. Phlox leaves are covered with brown spots.
- Ring spotting. All phlox is covered with bright spots. The disease causes a black-ringed tomato virus.
Fungal diseases and their features
Fungal diseases also pose a great danger to phlox. If you do not cure them on time, all plants will fall ill. The infected phlox looks weak and ugly. The main types of fungi: phomosis, powdery mildew, septoria, rust.
- Phomosis. The disease manifests itself during tying buds. In this case, the root foliage dies, and the shoots darken, and the phlox stops growing. Often, along with fomosis, a nematode appears.
- Septoria. A common fungal disease characterized by the appearance of spots on the leaves. Over time, spots grow, and phlox leaves begin to turn yellow.
- Powdery Mildew The most common phlox disease that occurs during heat. You can recognize the ailment by white coating on different parts of the plant. A flower loses its appeal and stops growing. Leaves gradually dry and fall.
- Rust. Brown spots and spots appear on the leaves of the plant. Over time, the foliage falls, and the plant dies.
- Nematode. Phlox stems cease to grow or lag behind in growth. The pest is not visible to the naked eye. To avoid the appearance of such a problem, it is worth planting marigolds next to phlox.
Phlox: landing and care
Features of Noncommunicable Diseases
Noncommunicable diseases appear due to non-compliance with agricultural technology. With a lack of water, phloxes begin to fade, dry air leads to the same problem. With excess moisture, the root color system rots.
If there is an excess of nitrogen on wet days, the stem may begin to crack in the plants. A similar problem occurs when thickening landings.
Mycoplasmal Phlox Disease
These diseases are infrequent, so they are difficult to recognize. Bright representative - the disease "Jaundice". It is marked by a lag in plant development. This loses its color and shape of the foliage, and a large number of side shoots appear on the stems. Stamens and leaves with jaundice begin to reborn.

How to deal with phlox diseases
Fight phlox diseases immediately, without delaying, otherwise you risk losing the plant. It is especially necessary to act quickly when viruses appear.
To get rid of viral diseases, you should periodically inspect the plantings and remove the affected plants. Before planting, it is worth checking whether the soil is infected with nematodes. It is recommended that the newly acquired varieties be first planted away from phloxes, and after a while, making sure that everything is in order with them, you can put them in the main colors.
Fungal Disease Control
In the presence of fungal diseases, infected parts of plants must be removed. They are cut and burned. The soil near phlox is treated with a solution of iron sulfate or Bordeaux fluid.
Noncommunicable Disease Control
In the fight against noncommunicable diseases, only compliance with agricultural technology will help. Phlox requires feeding, loosening and mulching the soil, watering, weed control.
In winter, plants should be protected from freezing with shelter with a heater. In the autumn period, it is necessary to prune the stem to ground level.
Mycoplasma disease control
Jaundice can be destroyed only by eliminating diseased plants. But subject to the rules of agricultural technology, the disease does not appear.
So, even hardy phloxes can get sick. That is why it is important to be able to determine what the plant suffers from and how to help it recover quickly. If no action is taken, all landings can be lost.
