Assistant Lecturer Ghufran Abbas Mohammed, a faculty member in the Department of Life Sciences at the College of Education for Pure Sciences, University of Samarra, has published a scientific paper in the Thi-Qar Journal of Agricultural Sciences.

The research, entitled “Biological Control of Soil-Borne Fungi Affecting Tomatoes Using Aspergillus niger and Trichoderma harzianum,” aimed to evaluate the antagonistic potential of Aspergillus niger and Trichoderma harzianum against several major soil-borne pathogenic fungi under laboratory conditions, including Fusarium oxysporum, Alternaria solani, Pythium aphanidermatum, and Sclerotinia sclerotiorum.

The researcher used fungal inocula of the two fungi, prepared on millet seeds, to inoculate sterilized soil formulated with a gypsum-based substrate and sterilized using polyethylene and formalin. To assess the effects of the different treatments on plant growth, tomato seedlings of the “Super Queen” cultivar with similar heights were planted in sterilized pots, with three replicates for each treatment.

The study results showed that Trichoderma harzianum achieved the highest efficiency in promoting tomato plant growth. It was also identified as the most effective biological control agent among those tested due to its strong ability to suppress pathogenic fungi and improve tomato development. Furthermore, T. harzianum exhibited strong antagonistic activity against the pathogen Fusarium oxysporum and significantly reduced its harmful effects on tomato plants.
