The complementary reaction through heterokaryon formation between nitratenonutilizing (nit) mutants of Fusarium moniliforme was studied to understand the development mechanism to benomyl resistance. A benomyl resistant isolate with MIC value of 1600ppm showed the complementary reaction with less resistant ones (50≤MIC≤800) obtained from the same location in Tochigi, The complementary reactions between isolates obtained from different locations were rare. This result suggests that F. moniliforme may acquire benomyl resistance through heterokaryon formation and isolates from different origin do not belong to same vegetative compatibility group.
