The interaction of three populations of Pratylenchus thornei (SK11, SK24 and YLVC24) and Fusarium culmorum B4 isolate on Ikizce wheat variety were investigated under controlled conditions with simultaneous and sequential inoculations. In the study, 1000 larva+adult inoculum density was used for nematode populations, while 50% diluted culture filtrate concentration was used in the fungal inoculum and 5 mL was applied to each pot. After about seven weeks, the wheat plants were removed and evaluated in terms of disease severity, final nematode density in soil and root, and nematode reproduction rate. It has been determined that the pathogenicity of the nematode populations is important in nematode and fungi interactions in the study. No interaction could be detected between the fungi and YLVC24, which has the lowest reproduction rate (6.6 +/- 0.1) among the populations, on wheat. In the SK24 population with the highest reproduction rate (10.4 +/- 0.4), the final nematode density was found to increase in simultaneous nematode and fungi application (12240.0 +/- 446.8), and fungi inoculation two peeks after nematode application (11672.0 +/- 389.3) compared to only nematode application (10436.0 +/- 446.8). When fungi was inoculated two weeks before nematode application on wheat, the population densities of SK11 and SK24 decreased. No difference was found between nematode populations in disease severity caused by fungi on wheat simultaneous and sequential inoculations. It was determined that fungi application time was effective on total nematode density and reproduction rate of SK11 and SK24 populations. In the study, synergistic interaction was found only between the P. thornei SK24 population and F. culmorum in wheat.
