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.
Bacterial Leaf Spot

The bacteria infect leaves through wounds or natural openings, causing characteristic lesions that can lead to premature leaf drop and plant weakening.
Bacterial Blight
Bacterial blight is a serious plant disease caused by pathogenic bacteria that enters plants through wounds or natural openings. It spreads rapidly in warm, wet conditions and can cause significant damage to leaves, stems, and flowers. The bacteria are transmitted by water splash, contaminated tools, and insects.
Leaf Spot
