Pests
Indoor chrysanthemum is more often visited by aphids and thrips, less often by spider mites. You will guess about the appearance of parasites by the appearance of the flower - the leaves will begin to turn yellow, traces of insects, sticky secretions or a white cobweb will appear on them. The plant urgently needs to be saved. Wash the chrysanthemum under a warm shower in the bathroom - more parasites will be washed off with the water. Then the flower must be treated with some kind of insecticide against insect pests. Aktara, Aktellik, Fitoverm and many other insecticides are sold in stores with instructions. Read them and process the plant according to the instructions.
Autumn comes, the day is getting shorter, it gets colder outside. The bulk of indoor flowers have already faded and are preparing for rest. And for the room chrysanthemum, the desired flowering time has come. For almost a year, she was carefully looked after, preserved her beauty and health, and now she, as if in response, bloomed with magnificent multi-colored, very bright, inflorescences. Isn't it a tempting picture ?! Try and grow this wonderful plant on your windowsill. With proper care of it in spring and summer, you will admire its magnificent flowering throughout the fall.
Diseases
Diseases of a viral nature:
- Aspermia. This disease leads to deformation of flowers and mottling of chrysanthemum leaves.
- Seedlessness. Chrysanthemum varieties with a bronze-red tint of inflorescences are susceptible to this infection. The flowers of the diseased plant become yellowish. The ligulate flowers of diseased chrysanthemums are deformed, becoming of different lengths.
- Dwarfism. This disease provokes a delay in plant growth and early flowering with deformed flowers.
- Ring spot. This viral infection causes yellowish rings to form on the leaves of the plant. The leaves are deformed and shrink.
- Mosaic. This viral infection leads to the formation of mosaic spots on the leaves.
There is no cure for viral infections. A diseased plant must be destroyed along with the soil. The pot can be disinfected, and only then can it be used. In order not to infect other flowers with viruses, it is advisable to sterilize all the instruments used.
Diseases of fungal origin:
- Powdery mildew. This infection mainly destroys young shoots, covers the leaves and flowers of chrysanthemum with a white, mealy, bloom.
- Rust. This is also a fungal disease. Leaves turn yellow, shoots become brittle. The plant becomes covered with round brown spots and fungal spores.
- Septoria. The infection affects the leaves of the chrysanthemum. The spots on them appear first yellow, and then dark brown. The untreated plant will die.
- Gray rot. Brown spots will appear throughout the plant, which in turn become covered with a gray bloom. The chrysanthemum starts to rot.
We recommend treating fungal infections with chemical preparations - fungicides. Copper oxychloride and Fundazol treat rust, septoria and gray rot well, and Bordeaux mixture is used against powdery mildew. Modern drugs, such as Fitosporin, cope with all types of fungal infections.
All these diseases are rather dangerous for garden species of chrysanthemums, as well as for those indoor ones that you planted in the open ground for the summer. The infection enters the flower from the soil or is carried by insect pests from diseased plants. When grown indoors, chrysanthemums rarely get sick with infectious diseases. However, if the basic rules for caring for a indoor flower are violated, non-infectious problems may arise.
