Powdery mildew causes a white, powdery coating on the leaves, while gray mold causes grayish-brown spots on the leaves and stems. Root rot causes the plant to wilt, turn yellow, and eventually die. To manage these diseases, ensure that you avoid over-watering and provide proper drainage to the plants. You can also use fungicides such as copper-based products or sulfur dust to control powdery mildew and gray mold.
Conclusion
Managing pests and diseases for Bothriocline auriculata (M.Taylor) C.Jeffrey is essential as it can impact the plant's growth and development. By regularly inspecting your plants for signs of pests and diseases and taking appropriate action, you can keep your plants healthy and thriving.
