- Downy Mildew: A fungus that thrives in humid conditions, leading to yellowing leaves and stunted growth.
- Fusarium Wilt: A soil-borne fungus that can cause wilting and yellowing of leaves, ultimately leading to plant death.
- Botrytis Blight: Often seen in damp conditions, this fungus can cause gray mold on leaves and fruits.

Recognizing the symptoms of fungal infections is crucial for early intervention. Here are some signs to watch for:
