The disease thrives in warm, dry climates with high humidity and appears as a distinctive white powdery coating on plant surfaces.
Root Rot

It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.

Gray mold, caused by the fungus Botrytis cinerea, is a widespread necrotrophic pathogen affecting over 1,400 plant species. It thrives in cool, humid conditions and attacks weakened or aging plant tissues, causing soft rot and characteristic gray fuzzy growth.
Bacterial Leaf Spot
Bacterial leaf spot is a plant disease caused by bacteria in the Xanthomonas and Pseudomonas genera that affects various ornamental and edible plants. The bacteria infect leaves through wounds or natural openings, causing characteristic lesions that can lead to premature leaf drop and plant weakening.
