Interaction effect of Root Lesion Nematodes and Fusarium culmorum Sacc. on disease complex in some wheat cultivars

The study was conducted to assess a possible interaction between fungal pathogen of Fusarium culmorum Sacc. and Root lesion nematodes at sequentially simultaneously inoculation. spore suspension effect evaluated on plant disease severity nematode density moderate resistant wheat line F. (2-49) susceptible variety (?kizce) under controlled condition. higher ?kizce cv. than 2-49. This indicates that there is considerable important resistance. Simultaneous sequential inoculation Pratylenchus thornei reduced the final reproduction rate more with only P. penetrans F.culmorum (N+F) affected positively N+ F treatment neglectus cv., whereas negative found in pre or post treatments. No synergistic interactions were detected 2-49 when plants co-infected by root fungus. It determined had positive it entered before cv.. decreased applied four weeks after In differences species nematodes.
