ABSTRACT

Mycotoxigenic fungal species are a major cause of various infections in plants and their post-harvest produce that pose a serious threat to humans and animals. In the current study, the objective was to examine the in vitro efficacy of different concentrations of methanolic leaf extract of Sorghum halepense (L.) Pers. against target pathogenic mycotoxin producing fungal species (Trichoderma viride Pers., Trichoderma harzianum Rifai. and Cladosporium cladosporioides (Fresen.) G.A. de Vries. For this purpose, different concentrations viz. 2%, 4%, 6%, 8%, and 10% of methanolic leaf extract were prepared and tested for their antifungal potential in a completely randomized design. All the applied concentrations of S. halepense leaf extract inhibited the growth of all the tested fungal strains. Maximum growth inhibition (84%) was observed in 2% of the concentration of the extract against Cladosporium cladosporoides. On the other hand, the minimum reduction was observed in 4% of concentration of methanolic extract of S. halepense against T. viride as compared to control. The phytochemical analysis was also conducted to check which chemical entities are present in the extract that accounted for the antifungal potency of methanolic extract of S. halepense. Results of the phytochemical analysis revealed the occurrence of saponins, alkaloids, coumarins, flavonoids, and tannins while the plant was devoid of terpenoids, phlobatannins, and glycosides. Hence it can be concluded that the methanolic leaf extract of the tested plant effectively inhibited the growth of test mycotoxigenic fungi.
