Abstract

Abstract The Ergosterol‐biosynthesis inhibiting (EBI) fungicides had a prolonged inhibitory effect on the growth and sporulation of the fungus, Venturia inaequalis thereby preventing development of typical apple scab symptoms. Atypical lesions in the form of chlorotic or reddish brown flecks had reduced viable sporulation with deleterious effect on subcuticular hyphae when fungicide was applied beyond 144 h but before 170h after inoculation. Myclobutanil (45μg a.i./ml) had the maximum inhibitory effect on sporulation and colony growth while bitertanol (187.50 μg a.i./ml) showed only a temporary inhibition of fungal growth and sporulation. Ultra‐structural studies also exhibited different levels of fungitoxicity by different fungicides when applied 144 h after inoculation.
