Recently I observed lesions of leaf mold of tomato in our high tunnel at the Southwest Purdue Ag Center. I thought I would share these photos since the lesions can be variable.

Figure 1. Leaf mold of tomato often causes rather bright yellow lesions on the upper surface of the leaf.

Figure 2. When the tomato leaf with leaf mold is turned over, the underside exhibits the gray-green mold that give the disease it’s name.
More information about this disease can be found at here.
