Amin 6200146The effect of Trichoderma species in control of root- rot fungus, Fusarium solani, root-knot nematode, Meloidogyne javanica or reniform nematode, Rotylenchulus reniformis disease complex and on growth of sunflower plant was studied under greenhouse conditions. Treating two weeks old sunflower seedlings cv. Giza 1 with Trichoderma harzianum, T. viride, T. koningii, T. reesei or T. hamatum gave highly significant effect in control of fusarium-rot disease incidence and nematodes infection on sunflower roots. Infection of F. solani was highly increased in M. javanica infested soil than R. reniformis. Treatments of Trichoderma species led to decreasing Fusarium cfu counts in soil, infested with either M. javanica or R. reniformis and also significantly improved the plant growth parameters. T. hamatum, T. harzianum and T. koningii gave the greatest reduction in disease incidence caused by Fusarium, M. javanica or R. reniformis infestation. Generally, there was highly significant reduction in the number of fusarium-wilt disease and nematode population and increases in plant growth parameter of sunflower when treated with Trichoderma species.]]>Amin, A.W.,1999Meloidogyne javanica and Helicotylenchus dihystera.]]>3125137Amin, A.W. and M.M.A. Youssef,1997Meloidogyne javanica and Rotylenchulus reniformis infecting sunflower in Egypt.]]>7198200Ara, J., S.
