Sphagnum moss pests and control methods

What to do if powdery mildew appears on Sphagnum

Because the flower of the orchid often blooms after the rainy season, whether in the south or north of China, the air humidity after the rainy season is very high, which is the most unfavorable time for the growth of the orchid.

If powdery mildew occurs, spray carbendazim or triadimefon once. Carbendazim or triadimefon can both eliminate and prevent powdery mildew. When the air humidity is high, you can spray some even if no symptoms appear.
