Pseudomonas syringae pv. lachrymans (PSDMLA) is a Gram-negative bacterial pathogen that causes angular leaf spot in cucurbits, particularly cucumbers and melons. The bacterium spreads through contaminated seeds, irrigation water, and rain splash, thriving in warm (25-30°C), humid conditions. Infection results in water-soaked lesions that become angular and brown, often leading to premature leaf drop and fruit blemishes. Severe cases can reduce yields by 30-50%. Management includes using pathogen-free seeds, copper-based bactericides, and avoiding overhead irrigation. Crop rotation (2+ years) and removing infected debris are essential. Resistant cucumber
varieties provide partial protection. Early detection through PCR helps implement timely control measures.
