The Causes and Treatment Methods of T-J Disease in Clivia Miniata
Here we share the causes and treatment methods of T-J disease in Clivia Miniata, let's get to know more about it.
The Causes and Treatment Methods of T-J Disease in Clivia Miniata
T-J disease in Clivia Miniata is caused by the infection of T-J bacteria, commonly occurring in high temperature and humidity environments. Overwatering, dense placement, and excessive application of nitrogen fertilizer can easily lead to the disease. In summer, due to excessive soil moisture, excessive nitrogen fertilizer use, and lack of phosphorus and potassium fertilizers, T-J disease is easily caused. Penicillin or streptomycin can be used for treatment, and spraying oxytetracycline with 4000-5000 times water solution is most effective.
The Causes of T-J Disease in Clivia Miniata
T-J disease in Clivia Miniata is mainly caused by T-J bacteria infection, commonly occurring in high temperature and humidity environments. Overwatering, dense placement, and excessive application of nitrogen fertilizer can easily lead to the disease. This disease often occurs at the tip or edge of the leaves. In summer, due to excessive soil moisture, excessive nitrogen fertilizer use, and lack of phosphorus and potassium fertilizers, T-J disease is easily caused.
Symptoms of T-J Disease in Clivia Miniata
T-J disease in Clivia Miniata often occurs in rainy and humid seasons. Initially, the leaves show pinkish mucilage, which later turns into red-purple or dark brown circular or oval spots with a sunken center, light brown or white in the middle, which gradually expand with a ring-like pattern around them, and then become dry and crumbly, with black granular matter scattered on the spots. In severe cases, the leaves will turn black and wither.
Treatment for T-J Disease in Clivia Miniata
T-J disease in Clivia Miniata can be treated with penicillin or streptomycin, and spraying oxytetracycline with 4000-5000 times water solution is most effective. The plant will recover after the T-J disease is treated.
Prevention and Control Methods for T-J Disease in Clivia Miniata
1. When planting Clivia Miniata, choose a superior variety with strong disease resistance to avoid more diseases and pests during growth. Use disease-free nutrient soil or disinfect the soil to reduce the initial infection source and apply more phosphorus and potassium fertilizers to enhance the plant's disease resistance.
2. During the maintenance of Clivia Miniata, implement ecological control measures, maintain good ventilation, promote moisture removal, keep the humidity in the greenhouse around 60%, avoid spraying water on the leaves, and keep the soil not too moist. Make sure to take drainage measures during the rainy season.
3. At the early stage of T-J disease, spray promptly with methyl thiophanate, chlorothalonil, methyl thiophanate suspension, benomyl, carbendazim, mixed kill sulfur suspension, or T-J captan. Choose one of them, apply every 7-10 days, and continue for 2-3 times.
