Are you curious about the causes and treatment methods of Chrysanthemum (T-J) Disease in relation to green plants? The site editor will introduce the information to netizens next.
Cause and Treatment of Chrysanthemum (T-J) Disease
Chrysanthemum is prone to (T-J) disease under high temperature and humidity or excessive application of nitrogenous fertilizers. You can spray carbendazim wettable powder, (T-J) fuming wettable powder, mixed sulfur suspension, Yingde suspension, Duoke mycin wettable powder, and Shibaike wettable powder, once every 10 days, for 3-4 consecutive times. Strengthen management, ensure ventilation and lighting, and take drainage measures during the rainy season.
Causes of Chrysanthemum (T-J) Disease
Conidiospores are produced under favorable conditions and are spread by air currents or irrigation. High temperature and humidity or excessive application of nitrogenous fertilizers can easily cause Chrysanthemum (T-J) disease.
Symptoms of Chrysanthemum (T-J) Disease
Round spots will appear on the leaves of chrysanthemums, while elliptical spots appear on the stems, with a dark brown color, a lighter center, and dense black dots, which are the conidial plates of the pathogen. When the disease is severe, the spots merge together, and the stems and leaves quickly wither.
Treatment of Chrysanthemum (T-J) Disease
Chrysanthemum (T-J) disease can be controlled with carbendazim, (T-J) fuming, mixed sulfur suspension, Yingde suspension, Duoke mycin, and Shibaike.
Chrysanthemum (T-J) disease can be treated with tebuconazole, Saishi, and propiconazole as therapeutic agents, or with mancozeb, chlorothalonil, and pyraclostrobin as protective agents.
Prevention and Treatment of Chrysanthemum (T-J) Disease
Firstly, choose chrysanthemum varieties with strong resistance to diseases, practice crop rotation, disinfect the soil, strengthen management, ensure ventilation and lighting, take drainage measures during the rainy season to prevent moisture retention or overly wet potting soil, and use formula fertilization techniques to enhance disease resistance.
Medicines can be sprayed at the early onset of (T-J) disease, such as carbendazim wettable powder, (T-J) fuming wettable powder, mixed sulfur suspension, Yingde suspension, Duoke mycin wettable powder, and Shibaike wettable powder, once every 10 days, for 3-4 consecutive times.
The above information is about the causes and treatment methods of Chrysanthemum (T-J) disease, hoping it helps you!
