Abstract:	In February 2001, rust caused by Phakopsora pachyrhizi was detected for the first time on soyabean (Glycine max) near Vryheid in northern KwaZulu-Natal, South Africa. As the season progressed, the disease was also observed in other parts of the province, and epidemic levels were reached in the Karkloof, Cedara, Howick and Greytown production regions. In affected areas, infection foci gradually increased in size and caused premature yellowing and defoliation of soyabean crops, usually after the flowering stage. Typical rust symptoms were produced predominantly on the lower surface of soyabean leaves. Soyabean rust subsequently spread to Amsterdam and Ermelo in the High veld region of South Africa.
