In vitro ASSESSMENT OF Trichoderma asperellum ISOLATED FROM PLANT RHIZOSPHERE AND EVALUATION OF THEIR POTENTIAL ACTIVITY AGAINST SOME PATHOGENIC FUNGI

Abstract

ungal pathogens can cause dangerous and invasive diseases in economic plants in the world. The pathogenic fungi, in particular, soil borne pathogens act a significant agent in the important losses of agricultural resources in the developing world. Accurate and definitive fungal identification are essential for correct disease diagnosis and treatment of associated with fungal infections. Biological control of plant pathogens using Trichoderma species becomes a natural friendly ecological approach to overcome hazards associated with chemical fungicides which cause of many environmental pollutions and development of resistant strains (Widyastuti et al., 2003). Antagonistic strains of Trichoderma have indirect and direct mechanisms for inhibition growth of plant pathogenic fungi and improve the overall health of plants, indirectly by competing for nutrients and space. The indirect and direct mechanisms may act coordinately, and their importance in the biocontrol process depends on the Trichoderma spp., the crop plant and the environmental conditions (Benitez et al., 2004). The antagonistic and mycoparasitic potential of the T. asperellum strains were evaluated in vitro and in vivo, and they

Molecular characterization of selected fungal and bacterial endophytes in acid lime

“…Pseudomonas aeruginosa was identified as the endophytic phosphate-solubilizing bacteria EPR13 that was isolated from the aerial tissues of Achyranthes aspera L. (Misra et al, 2012). Similarly, Hassan et al (2016). Amaresan et al (2014) isolated and characterized the beneficial bacteria associated with chilli at molecular level by 16 s rDNA sequencing.…”
