Abstract

A common soil-borne plant pathogen called Fusarium sp. causes ailments including root rot. A secure method to avoid the issues associated with fungal diseases that reduce agricultural production is biological control of plant disease. Eight Trichoderma isolates were isolated from soil surrounding healthy tomato roots in various parts of Dakahlia Governorate, The most successful isolate of Trichoderma was Trichoderma atrovirde, which had a 91.89% percentage inhibition against Fusarium equiseti after being tested using a dual culture method. T. atrovirde treatments enhanced tomato plant growth parameters compared with control plants or plants that were simply infected, as well as an increase in photosynthetic pigments and relative water content was observed in response to T. atrovirde treatment. Additionally, decreased in proline content, saturation water deficit and disease incidence percentage (40.55%) were also detected, compared to plants that were solely infected (74.21%).Based on the obtained results, Trichoderma atrovirde could be used as a biological control against root rot disease of tomato plants.
