Then the effect of&nbsp;</span><em>G. etunicatum</em><span style="background-color:rgb(255, 255, 255); font-family:arial,verdana,sans-serif">&nbsp;inoculation on&nbsp;</span><em>Fusarium</em><span style="background-color:rgb(255, 255, 255); font-family:arial,verdana,sans-serif">&nbsp;wilt was investigated by pot and greenhouse trials. AMF increased both root and shoot lengths of the plants and also retarded the wilt disease development and reduced disease rates.</span></p>
