Demonstration of an Effective IPM Program for Fungal Leaf Blight Diseases of Carrots

Abstract

Fungal leaf blights (spots) caused primarily by Alternaria dauci and also Cercospora carotae are among the major disease impacting carrot production in New York. Although considerable information is available on the epidemiology and even the forecasting of these diseases, their control continue to depend largely on the frequent application of fungicidal sprays.
