Abstract To test the effect of seed treatment with fungicides on the development of mycorrhizal fungi, bean seeds were treated with fungicide dry or vehicled in the organic solvents, ethanol or dichloromethane and then planted in soil inoculated with the mycorrhizal fungus Glomus macrocarpum and/or the plant pathogenic fungus Fusarium solani. Measurements were made at 4 day intervals, to evaluate the location and extent of colonization of either Glomus macrocarpum or Fusarium solani in the root system. Most combinations of fungicide-solvent had little effect on the extent of colonization by each fungus individually. However, when both fungi were inoculated together, symptoms of F. solani were seen only in the tips of roots which indicate that the mycorrhizal fungus was able to limit the occurrence of the pathogenic fungus.
