Efficacy of Trichoderma harzianum as a Natural Biocontrol and Growth-Promoting Agent Against Selected Tomato Fungal Pathogens
Tomato production faces serious pressure from fungal pathogens, which reduce yield and quality. Biological control could be an approach to minimise the impact of some pathogens by using antagonistic fungi such as Trichoderma species. Trichoderma harzianum has been used widely as a biocontrol agent due to its antagonistic properties against different plant pathogens and its ability to promote plant growth. The present study deals with the efficacy of T. harzianum, isolated from the tomato rhizosphere, in controlling selected fungal pathogens of tomatoes, including Fusarium solani, F. acuminatum, Rhizoctonia solani and Phoma destructiva based on in vitro and in vivo assays. The results showed that T. harzianum inhibited the growth of the above-mentioned pathogens by 88.0% to 100% in dual culture assays after 5–7 days. Tomato plants treated with T. harzianum demonstrated better root and shoot growth compared to untreated controls. In greenhouse tests, maximum disease reductions were recorded in tomato plants treated with T. harzianum and challenged with F. acuminatum (92.4%), P. destructiva (86.6%), R. solani (74.38%) and F. solani (72.76%) in comparison to non-treated. T. harzianum also showed a higher percent disease reduction compared to chemical fungicides. These findings suggest that T. harzianum could be used effectively in integrated pest management practices in fresh tomato cultivation.
期刊介绍：
Journal of Phytopathology publishes original and review articles on all scientific aspects of applied phytopathology in agricultural and horticultural crops. Preference is given to contributions improving our understanding of the biotic and abiotic determinants of plant diseases, including epidemics and damage potential, as a basis for innovative disease management, modelling and forecasting. This includes practical aspects and the development of methods for disease diagnosis as well as infection bioassays.
Studies at the population, organism, physiological, biochemical and molecular genetic level are welcome. The journal scope comprises the pathology and epidemiology of plant diseases caused by microbial pathogens, viruses and nematodes.
Accepted papers should advance our conceptual knowledge of plant diseases, rather than presenting descriptive or screening data unrelated to phytopathological mechanisms or functions. Results from unrepeated experimental conditions or data with no or inappropriate statistical processing will not be considered. Authors are encouraged to look at past issues to ensure adherence to the standards of the journal.
