Description:
On dark tobacco, narrowleaf madole shown, the spots have a little bit different look on dark tobacco because you do not usually see the yellow halo you will see on burley varieties, although a grouping of spots can cause an area of the leaf to turn yellow. Also interior portions of the spots look darker than those on burley.
