Determination of physiological races of Fussrium Oxysporium f.sp. Dianthi in carnation in the savanna of Bogotá ; Determinación de las razas fisiológicas de Fusarium Oxysporum f.sp. Dianthi en clavel en la Sabana de Bogotá

Vascular wilt caused by the fungus Fusarium oxysporum f. sp. dianthi is the most important disease on carnation in Colombia. Although the use of resistant varieties is an economical and promlsmg method for the management of the disease, some varietiss do not behave in a similar wayin different farms, and there are evidences of the variability ofthe pathogen. The objective of this research was to determine the presence of physiological races, of the pathogen in the Bogota Plateau. One hundred isolatesof the pathogen were obtained in 49 farms from different varieties of standar and miniature car... Mehr ...
