Abstract

Two beneficial microorganisms Glomus  intraradices and Trichoderma  harzianum  were tested for  their ability to suppress Fusarium wilt of Pepper caused by Fusarium oxysporum f.sp. capsici. The results showed that  G.  intraradices  and T. harzianum controlled the wilt disease reducing disease incidence to (28 ,19.6% and 23 ,14,6%) compared with control (38.3 ,25% )  in the two verities of pepper plant California Wonder and Local verity respectively . This pathogen significantly reduced plant growth as measured by dry root weight and dry shoot weight . Overall, T.harzianum  and G. intraradices  caused significant increasing  in  phenol amount (91.3,118.7 and 80.3,104.4 µg g-1 FW) , chlorophyll contents  ( 28.3,31.7 and 23.7, 26.4 mg/g FW ), % Carbohydrate (1.63,1.82% and 1.39,1.53% ) compared with control (63 ,81.9 µg g-1  FW ,18.4,20.55 mg/g FW and 1.08, 1.19% )  in the two verities of pepper plant  California Wonder  and Local verity respectively .
