【 摘 要 】

One of the main obstacles to feeding the world is the fungal leaf spot disease, which has a negativeimpact on plants' photosynthetic areas and significantly lowers crop quality and output. To managefungi that pose a serious hazard to both humans and the environment, various chemical fungicidesare utilized. The goal of the current study was to determine whether local isolates of threeTrichoderma spp. (Trichoderma viride, Trichoderma harzianum, and Trichoderma asperellum)had any antagonistic effects in vitro against the pathogenic fungi Alternaria alternata, Fusariumsolani, Fusarium oxysporum, Aspergillus flavus, Aspergillus sydowii, and Alternaria sp.Trichoderma viride showed the greatest growth inhibition against all of the tested pathogenicfungi, followed by Trichoderma harzianum and Trichoderma asperellum. It was shown that allthree Trichoderma species strongly inhibited the mycelial growth of fungal pathogens. Comparedto other isolated fungi, Trichoderma species inhibited Alternaria alternata mycelial growth more,whereas in Fusarium oxysporum least amount of mycelial growth inhibition was observed. Thesefindings imply that Trichoderma species can function as an effective biocontrol agent against thefungi responsible for tomato leaf spot disease.
