Exploring the dual role of fungi in plant ecosystems, this content delves into their contribution to both disease and health. It covers the identification and management of fungal diseases like rusts, powdery mildews, and botrytis, as well as strategies for controlling powdery mildew and eliminating fungus gnats in indoor plants. The use of fungicidal sprays and proactive measures to prevent fungal infections are also discussed, providing a comprehensive guide to maintaining plant health.
