SCLOCE
Stromatinia cepivora is a soil-borne fungus that causes white rot in onions, garlic, and other Allium crops. It produces small black sclerotia that can survive in soil for decades and germinate only in response to Allium root compounds. It spreads through contaminated soil, bulbs, and equipment, thriving in cool, moist conditions.
