Effect of Fusarium Culmorum Spore Suspension on Mortality of Root Lesion Nematodes in Vitro Conditions

Abstract

Three different Fusarium culmorum isolates (B4, ISP, Fc5) were used in the study and the effects of these spore suspension of isolates were investigated on the root lesion nematodes Pratylenchus thornei, P. neglectus and P. penetrans in vitro. As a result of evaluating the percent mortality rate, ISP isolate had the highest mortality effect on root nematodes and more effective on P. thornei. The lowest mortality effect of isolate was Fc5. However, Fc5 effect on P. neglectus was higher than ISP and B4 isolates. Percentage of mortality rate of B4 isolate were found 16.2 on P. penetrans, 13.1 on P. thornei and 5.5 on P. neglectus and showed the lowest effect on P. neglectus. It was found that F.culmorum spore suspension could suppress root lesion nematodes at low levels in vitro and changed depending on the isolates.
