Mycosphaerella

About Mycosphaerella

Leaf spot caused by Mycosphaerella fungi appears as small, round to irregular brown or tan spots on iris leaves, often with a yellow halo. This disease thrives in warm, wet conditions common in Middle Tennessee, including areas like Franklin and Brentwood, leading to premature leaf dieback and reduced plant vigor. Proper spacing and removing infected foliage can help manage its spread in home gardens.
