Measurements were made at 4 day intervals, to assess the presence of mycorrhizae or disease in the roots as well as top dry weight, root fresh weight and root length. Fungicidal seed treatment did not affect the initial occurrence of mycorrhizae, number of spores of G. macrocarpum in the soil or root length. Fresh weights of roots and dry weights of tops were greater in the presence of the mycorrhizal fungus. The onslaught of symptoms by F. solani was significantly retarded by treatment with fungicides plus mycorrhizal fungi or fungicides plus organic solvents.pdfengSpringer Nature Switzerland AG.BenomylCaptanDichloromethaneEthanolFresh root weightTop dry weightFungicidal seed treatmentFusarium solaniGlomus macrocarpumPhaseolus vulgarisArtigo
