SHARFUN-NAHAR AND MUHAMMAD MUSHTAQ
Abstract
Pathogenic effects of 6 Fusarium spp., viz., F. equiseti, F. longipes, F. scirpi (Section Gibbosum), F. oxysporum (Section Elegans), F. pallidoroseum (Section Arthrosporiella) and F. solani (Section Martiella) were studied on sunflower plants. Symptoms produced by Fusarium spp., were root-, collar-, stem- and seedling rots, damping-off, stunting, wilting, tip burning and reduction in growth. Wilting and seedling rot were found to be the most prominent symptoms produced by all Fusarium spp. Highest wilting was observed in plants inoculated by F. equiseti, F. scirpi and F. solani, whereas, highest seedling rot was observed by F. solani.
