Orchid Stem Rot Prevention and Introduction
Sharing content about orchids, a member of the Orchidaceae family. This includes the prevention and introduction of orchid stem rot. Next, the editor will provide an introduction.
The prevention of orchid stem rot primarily involves prevention, followed by treatment, with prevention being the key. Treatment can only be considered a rescue measure. In the summer and autumn seasons, with frequent rain and high humidity, orchids are particularly susceptible to stem rot, which is a critical stage for preventing this disease. Good ventilation and regular disinfection of the growing area are necessary. Starting in May, it is recommended to spray antibacterial agents (such as carbendazim, metalaxyl-M, mycotoxin cleaner, and Shigao) once a week for disinfection, including foliar spraying and comprehensive spraying in the growing area. The foliage should be slightly diluted, and the area slightly more concentrated. Based on years of practice, this method can effectively prevent the occurrence of stem rot.
【Treatment Methods】
First, remove the entire pot of orchids, clean them, and cut away the diseased and infected plants. Use a blade to thoroughly repair the腐烂 pseudobulbs, then soak the healthy parts of the orchids that should be retained in a slightly more concentrated disinfectant (Shigao) for no less than one hour. After drying, apply metalaxyl-M in a paste to seal the pseudobulb area, then dry it again. Wrap the pseudobulb area with disinfected aquatic plants, then repot using new soil and a new pot. After planting, do not water or expose to sunlight. Keep it separate from other orchids and place it in a well-ventilated area. Three days later, soak it thoroughly in clean water with streptomycin, then place it in a well-ventilated area for regular management. Every month, soak the pot in a disinfectant (slightly diluted) to gradually restore the health of the orchid plant. Orchid enthusiasts might want to try this method.
