Common name: Embellisia skin blotch and bulb canker of garlic
Latin binomial: Embellisia allii
Host plants: Primarily garlic. Skin blotch is the most common symptom caused by this fungus, and usually is a cosmetic blemish on the outer skin layers of garlic that does not affect consumer appeal unless sufficiently developed. Bulb canker consists of corky masses, primarily on the top or sides of individual cloves. If the first true leaf of a garlic seedling becomes infected, the leaf may be curled.
