Botrytis leaf blight

Botrytis squamosa

Symptoms: B. squamosa mainly attacks onion leaves. The first symptoms appear as a small white lesion on the leaf surrounded by a greenish halo. This early symptom can easily be confused with insect or mechanical damage, or herbicide injury. In later stages, the lesions expand and also many new lesions appear that cause premature die-back of leaves. Severely affected onion fields develop a blighted appearance that result in small size onion bulbs.
