Abstract

The distribution and importance of groundnut diseases in fields in Mzuzu and Karonga Agricultural Development Divisions of Northern Malawi were determined. In Mzuzu, early leaf spot (Cercospora arachidicola [Mycosphaerella arachidis]), late leaf spot (Phaeoisariopsis personata [Mycosphaerella berkeleyi]) and rust (Puccinia arachidis) were common. Late leaf spot and rust were particularly severe. Other disease recorded included leaf scorch (Leptosphaerulina crassiasca), web blotch (Phoma arachidicola [Didymosphaeria arachidicola]), phyllosticta leaf spot (Phyllosticta arachidis-hypogaea), anthracnose (Colletotrichum sp.) and sunflower yellow blotch umbravirus. Plants showing witches' broom were also observed. Witchweed (Alectra vogelii) was also recorded in almost all the fields surveyed. The disease spectrum in Karonga was similar to that in Mzuzu.
