Diedhiou and Hafsa Houmairi and Nalla Mbaye and Yaya Diallo and Bouchaib Bencharki", abstract = "The antagonistic action of Trichoderma koningii Audemas (M35) and Trichoderma longibrachiatum Rifai (M37) was studied in vitro against 13 strains of Fusarium sp. isolated from symptoms of mango malformation disease in southern Senegal. The antagonists and pathogens were cultured on Petri dishes containing PDA medium in direct and remote confrontation for 6 days at 28°C. The 2 Trichoderma species showed inhibitory activity on mycelial growth of the 13 Fusarium strains tested at varying rates according to the strain and confrontation method as well. Inhibition percentages in the presence of Trichoderma koningii Audemas (M35) ranged from 13.13 to 57.67 in the direct confrontation and from 3.33 to 33.33 in the remote confrontation tests. In the presence of Trichoderma longibrachiatum Rifai (M37), the inhibition percentages went from 09.80 to 37.03% in the direct confrontation. An antagonistic capacity against Fusarium strains was also observed in remote confrontations where the inhibition percentages ranged from 13.33 to 33.33%. Competition and mycoparasitism were the main modes of action shown to inhibit mycelial growth in the 13 strains tested. These results show the potential for using Trichoderma species as a means of controlling mango malformation disease.", issn = "23191473", journal = "IJAIR", keywords = "Antagonist;Fusarium;Mango Malformation Disease;Senegal;Trichoderma", month = "September", number = "2", pages = "89-96", title = "{I}n vitro {A}ntagonistic {E}ffect of {T}richoderma koningii {A}udemas and {T}richoderma longibrachiatum {R}ifai on {M}ango {M}alformation {D}isease in {S}outhern {S}enegal", volume = "10", year = "2021", }
