What are the common diseases of Clivia? How to prevent it?

The disease of Clivia is more common, and some of the bacteria are infected very quickly, which is very harmful to Clivia. Common white rickets, anthracnose, soft rot and so on.

1 White rickets: This disease, also known as sclerotium root rot, occurs on many flowers and has similar symptoms. At the base of the stems and leaves, water-stained brown irregular spots appeared, and white filamentous mycelium grew soon, spreading in the rhizosphere soil. And the small sclerotium is born, initially white, gradually yellowish, brown, like rapeseed, expanding to the entire base decay and necrosis. It is most likely to occur during the hot and humid seasons.

Prevention method: First, disinfection before sterilization. Second, for susceptible plants, remove the hyphae and sclerotia from the soil surface and the base of the leaf, apply 0.1% liters of mercury to the affected area, and apply 50% polyclonal 400 times solution to the diseased part and soil once a week. , 3 to 4 times in a row.

2 Bacterial soft rot: This kind of pathogen often invades from the wound. At the beginning of the disease, there are pale yellow water-stained spots on the leaves, which are then expanded into irregular lesions, which make the leaves brown and soft rot, and there are bacteria in the lesions. Overflowing, some are not soft and rot, and appear brown and dry, and the infection is very fast.

Control methods: First, disinfect the soil before planting. Second, separate the plants after the disease, cut off the diseased leaves, scrape the decayed part in the rhizome, apply sulfur powder, put it in a dry and ventilated place. Third, use penicillin or 4. Streptomycin 4000 ~ 5000 times liquid spray plant and disease department, has a certain effect.

3 Anthracnose: It occurs on many flowers, mostly on the leaves. The lesions are blue-yellow or yellow-brown in the later stage. When the leaves are severe, the whole leaves are atrophied and dry. The spray is too wet, the nitrogen is rich, and the rainy and hot season is easy to occur.

Control methods: First, maintain good ventilation conditions, avoid the impact of storms and rains, do not slam on the water when watering. Second, in the early stage of the disease, use 50% of polyclonal bacteria or 50% methyl thiophanate 500 times and 1% Bordeaux liquid spray, once every 10 days, for 3 to 4 times in a row, has a certain inhibition and prevention effect.
