Priming and discarding the bottom six leaves of dark fire-cured tobacco, increased the incidence of leaf damage caused by Alternaria longipes and Cercospora nicotianae. The stem rot Erwinia carotovora also caused more damage in primed than in unprimed tobacco. Leaving 18 leaves upon the plant as opposed to 15, decreased the incidence of A. longipes and C. nicotianae in tobacco from the top of the plant (leaves 13-15). At the recommended spacing of 0.9 0.9 m, applying a balanced fertilizer did not cause any increase in fungal damage to the leaf, but it did cause an increase in infection when applied at a spacing of 0.9 1.2 m. Decreasing plant populations and increased levels of applied fertilizer both increased the incidence of E. carotovora infection.
