Reflections on Heterodera rostochiensis1

Abstract

AbstractIn 1955, the EPPO Heterodera rostochiensis Conference held in Wageningen (Anon., 1955) came to conclusions and recommendations which are analyzed together with other papers issued by EPPO between 1951–1959.In the course of the 18 years which elapsed since the Conference, major advances have been made in the following fields:– Origin, spread and distribution of the nematode, numerical dynamics and distribution of the nematode.– Numerical dynamics and genetic density and flexibility of nematode populations.– Breeding resistant potato varieties.– Development of new nematicides and integrated control.– Ecological limitations.Progress achieved along these lines is reviewed.
