Abstract:

Potatoes are grown in Israel in two growing seasons, autumn and spring. Two foliar diseases, early blight (Alternaria solani) and late blight (Phytophthora infestans) threaten the crop and if not managed properly, may induce substantial yield losses. Concepts for the integration of genotype resistance, age-related resistance and fungicide type for the suppression of both pathogens were developed based on the epidemiology of the pathogens and in relation to their interactions with the host. The concepts were evaluated in 7 field experiments from 1994 to 1998. Analysis of disease progress curves revealed that in plots managed according to the integrated management concepts, early blight was suppressed as good as in plots treated with a specific fungicide against A. solani, and late blight was suppressed as good as in plots treated with specific fungicides against P. infestans. Less sprays and lower quantities of fungicidal active ingredients were applied in plots treated according to the integrated management strategy. Yield in the integrated management treatment did not differ, or was significantly higher, than yield in the other treatments.

Potatoes are grown in Israel in two growing seasons, autumn and spring. Two foliar diseases, early blight (Alternaria solani) and late blight (Phytophthora infestans) threaten the crop and if not managed properly, may induce substantial yield losses. Concepts for the integration of genotype resistance, age-related resistance and fungicide type for the suppression of both pathogens were developed based on the epidemiology of the pathogens and in relation to their interactions with the host. The concepts were evaluated in 7 field experiments from 1994 to 1998. Analysis of disease progress curves revealed that in plots managed according to the integrated management concepts, early blight was suppressed as good as in plots treated with a specific fungicide against A. solani, and late blight was suppressed as good as in plots treated with specific fungicides against P. infestans. Less sprays and lower quantities of fungicidal active ingredients were applied in plots treated according to the integrated management strategy. Yield in the integrated management treatment did not differ, or was significantly higher, than yield in the other treatments.
