What to Do When an Orchid Gets Anthracnose? Detailed Prevention and Treatment Methods

1. Tip the pathogen out, rinse it clean, tidy up the roots, cut away the rotten roots, and remove the diseased leaves. 2. Soak in an 800-fold imported thiophanate-methyl solution for 30 minutes, then place in a ventilated spot to dry. 3. Choose a sterilized new pot and a well-aerated mixed growing medium of orchid stone, crushed brick, and longan tree bark for replanting. 4. After watering thoroughly, place it in a cool, ventilated place to rest quietly. Becausecultivationmedium has good air and water permeability, depending on the state of the growing medium, water once every two to three days, and every fifteen days spray the leaf surfaces and substrate with chlorothalonil. 5. After careful care, in the early stage when the young shoots emerge, use a long-spout pot to water along the pot, avoiding rainwater directly entering the orchid heart, which causes seedling rot. When the young shoots are five to six cm tall, gradually let theorchidbathe in one to two hours of morning light, and occasionally apply a diluted low-concentration inorganic fertilizer (Hyponex No. 5 can be chosen) to make the young seedlings grow rapidly and robustly, further enhancing disease resistance. In seasons when the temperature gradually rises, to avoid the growing medium becoming overly dry, cover the pot surface with clean small-particle pond mud, and stop fertilizing. (Green Tea)
