Summary

Experiments were done during 1990/91 and 1991/92 at Bangalore to estimate the reduction in yield caused by powdery mildew (Erysiphe polygoni DC) on coriander (Coriandrum sativum L.) cultivars differing widely in time to maturity. Powdery mildew resulted in smaller reductions in yield in the early maturing than the late maturing cultivars. Although the results of this study suggest that even expensive control measures can be recommended for managing powdery mildew in late maturing cultivars, because a small increase in the severity of powdery mildew infection may cause a considerable economic loss, they also indicate that such measures may not be economically viable for early maturing cultivars.
