. Diseases and decays of Connecticut tobacco. Tobacco. 110 Connecticut Experiment Station Bulletin 432 is confined to the lower leaves. The dead spots vary in size from an eighth to a half-inch or more in diameter, but sometimes these run together to kill larger areas. They are commonly larger on Broadleaf than on Havana Seed. The spot differs in appearance from the wildfire spot because it is usually angular instead of round in outline, and lacks the broad, definitely margined. Figure 10. Angular leafspot on mature Broadleaf. Note the irregular angular outline of spots and difference in color

When there is any yellow around the spots, it runs off irregularly into the green and has no smoothly defined, outer margin. Another characteris- tic of blackfire is that the spots usually show several shades of brown, from tan to black, in the same spot. The accompanying photograph (Figure 10) shows a leaf of Broadleaf. On heavier leaves lue spots may be more circular.
