The most common
The most common tulip diseases are:
- Penicillous rot. The disease develops if the culture is stored in humid places. As a result of the lesion, brown spots are formed. To prevent the development of rot, try to carefully dig up the bulbs so as not to damage them. Thereafter, immediately placed in a shady and dry place. Before planting, they are treated with special agents that help protect the culture from putrefactive processes.
- Gray rot. Symptoms of the disease are small gray spots that appear in large numbers on the crop. The infection quickly infects neighboring plants, so affected tulips should be removed immediately. Most often, the disease develops in cold and damp weather.
To fight these diseases, Bordeaux mixture, Euporen and other means are used: Miedzian 50 WP, Bravo 500 SC or Kaptan 50 WP and Topsin M 500 SC.
For prevention, they try not to plant flower bulbs too densely, and they also choose only healthy specimens for planting and treat them with special preparations. When watering, avoid wetting the leaves. Damaged plant parts must be removed.
Most dangerous
The most dangerous tulip diseases:
- Viral mosaic. The disease is caused by a group of viruses that discolor the flower petals and leaves of tulips. Harms the plant and stops its development. The disease can be prevented by planting healthy bulbs and killing aphids that grow on plants. Diseased bulbs should also be removed to prevent transmission of viruses to healthy crops.
- Necrotic spotting. As a result of infection, spots appear on the shoots of leaves and flowers, the plant stops growing, the leaves are deformed and wither. Most often, necrosis develops before or after flowering. To prevent the development of the disease, gardeners try to plant only healthy bulbs and immediately remove the infected ones.
- Fusarium. The infection affects tulip bulbs. As a result of the disease, the culture first turns yellow, then withers, after which the bulb rots. When you press on it, you can see the release of yellow mucus. The development of the disease is exacerbated by multi-day showers and high temperatures. The disease also develops if the culture is stored in a room with high humidity.
Plant only healthy bulbs and take care not to damage them during transport or digging. Before planting, the culture is treated with chemicals. Bulbs are also observed during storage and diseased are removed. To avoid the development of fusarium, the culture should be stored at a temperature of about 10 ° C. Before planting, tulips are treated with preparations such as Topsin M 70 WP and Topsin M 500 SC.
Another common disease is variegation. A sign of damage is a change in the color of the tulip petals: multi-colored stripes begin to appear on them. This phenomenon is especially noticeable in red or pink colors. Color changes are hardly visible in varieties with white or yellow petals. The infection also affects the leaves (the stripes are parallel to the main nerves).
As a result of the defeat, the growth of tulips stops, and the root system also suffers. Variegation can develop if the crop is stored indoors where the temperature is too high. To prevent the development of the disease, gardeners try to dig up, throw away or burn the bulbs of diseased plants.
