Abstract
The spore concentration of 40,000 spores/ml is essential to produce disease consistently on all the leaves of five week-old plants excepting the top leaf. With increase in age of the plants, susceptibility toA. triticina increased. The intensity of disease decreased from base to top of the plants. In a resistant variety, only small specks appeared on the leaves. The pathogen entered the leaf generally by direct penetration and rarely through stomata. Germ tubes were restricted to the epidermal and occasionally to the subepidermal layer of the resistant variety.
