Bacterial Soft Rot
Bacterial soft rot is a destructive plant disease caused primarily by bacteria from the genera Pectobacterium (formerly Erwinia) and Dickeya. These bacteria produce enzymes that break down plant cell walls, causing rapid and foul-smelling tissue decomposition. It mainly affects succulent tissues such as tubers, fruits, stems, and bulbs, being especially problematic in warm and humid conditions.

They thrive in hot, dry conditions and can cause significant damage to ornamental and vegetable plants. During severe infestations, crop losses can reach 14% or higher as these pests disrupt vital plant processes including photosynthesis, carbon dioxide absorption, and transpiration.
