Evaluation of the Effectiveness of Commercial Biofungicide (Tricho Hstar) in Controlling fusarium Wilt Disease in Cuminum cyminum L

This study aims to assess efficacy of Ami Tricho Hstar, which includes Trichoderma harzianum, as a biocontrol agent for reducing Fusarium wilt in Cuminum cyminum L. Utilizing dual culture and agar well diffusion methods, Trichoderma harzianum was evaluated in vitro against Fusarium oxysporum.Such methods were used for their efficacy in evaluating fungal inhibition, providing accurate quantification of inhibitory effects and direct interactions between the biocontrol agent and the pathogen.Under field circumstances, parameters including the percentage of germination, the percentage of survival, the number of dried plants, and the crop yield were evaluated.The results demonstrated that in the dual culture and agar well diffusion experiments, Trichoderma harzianum showed zones of inhibition against Fusarium oxysporum that measured 41.1 mm 2 mm and 43.1 mm 3 mm, respectively.When compared to untreated plants, the application of Ami Tricho Hstar greatly improved metrics like the percentage of germination, the percentage of survival, the number of dried plants, and crop production.The present research introduced the application of Ami Tricho Hstar in a powder formulation at a rate of 40g per 15 litres of water resulted in considerable reduction in the prevalence of Fusarium wilt and notable improvements in seed germination and other plant development indicators.This study emphasizes its potential as a reliable biocontrol agent in agriculture.
