Cercospora leaf spot and powdery mildew of fenugreek, a potential new crop in Canada

Two diseases, Cercospora leaf spot and powdery mildew, were observed on the foliage of research plots of fenugreek ( fibonella foenum-graecuml in 1983. The leaf spot, caused by the fungus Cercospora traversiana, resulted in serious defoliation and also affected the stems and pods. It appears that Cercospora leaf spot possesses the potential to be a serious constraint to the production of fenugreek in Canada. Powdery mildew was not serious. Can. Plant Dis. Surv. 64:2,33-35, 1984. Deux maladies, la rayure nervale et le blanc, ont bt6 observbes sur le feuillage du fenugrec ( 7kigonella foenum-graecum) croissant sur des parcelles de recherche en 1983. La rayure nervale, caus6e par le champignon Cercospora traversiana, provoque une defoliation importante et affecte aussi la tige et les gousses. II semble que la rayure nervale puisse gener serieusement la production du fenugrec au Canada. Le blanc, quant A lui, ne fait pas de dommage sbrieux.
