In-vitro antifungal activity of the TA-1 strain at different concentrations against C. arachidicola. Ck (chemical fungicide) (A). An illustration of the negative control effects, CA (Ck), only inoculated with C. arachidicola), CA + TA-1 inoculated with C. arachidicola and treatment with TA-1 (B). SEM images of hyphal morphology of C. arachidicola after the treatment of TA-1 (up side, I, II, III), the arrows showing the deformations in the ultra-structure of mycelium of C. arachidicola and in Ck (control group), no treatment (down side, IV, V, VI) (C). An illustration of disease control efficiency on peanut early leaf spot, CA (Ck); only inoculated with C. arachidicola, CA + TA-1; inoculated with C. arachidicola + treated with TA-1, and CA + CF (Ck); inoculated with C. arachidicola + treated with chemical fungicide (D)
