A REVIEW: STEMPHYLIUM BLIGHT OF ONION-THE PATHOGEN, THE DISEASE, CURRENT STATUS AND DIFFERENT METHODS OF DISEASE MANAGEMENT

Crop Improvement

If you grow onions at home, Stemphylium blight is the fungal disease most likely to wipe out your crop before harvest — and knowing it exists is the first step to stopping it.

Onions are one of the world's most widely grown vegetables, used in cooking and medicine across many cultures. A fungal disease called Stemphylium blight has become the single biggest threat to onion crops, damaging both the bulbs we eat and the seeds farmers rely on to grow next year's crop. This review pulls together everything scientists know about the disease and the best ways to fight it.

Key Findings

1

Stemphylium blight is identified as the most serious and devastating fungal disease of onion, limiting both bulb and seed quality and quantity.

2

Onion (Allium cepa, 2n=16) belongs to the family Alliaceae and is rich in bioactive compounds including quercetin, with anti-inflammatory, anti-cholesterol, and anticancer properties.

3

Onion faces threats from a broad range of pathogens including fungi, bacteria, viruses, nematodes, and abiotic stressors, with Stemphylium blight ranking as the most impactful fungal disease.
