Fig. 3. Effects of G_app7 on growth of S. graminicola in infected pearl millet leaves. (A) Observation of S. graminicola sporulation in pearl millet leaves pretreated with G_app7 or
water control by stereo microscope. (B) Assessment of G_app7 inhibitory effects on sporulation of S. graminicola in leaves. Inhibition of S. graminicola zoosporangia (sporangia and
zoospores) by G_app7 was assessed by counting the empty and intact sporangia, and the zoospore release and movement in five different microscopic fields. Apron 35 SD, Amistar
250 SC were used as positive controls, while chloroform and distilled water as negative controls. Values are means of three independent replicates. Bars represent standard errors
(P < 0.05). Means followed by the same letter are not significantly different according to Tukey's HSD.
