Disease severity after leaves was infected by P. infestans. (A). Phenotypic changes of potato leaves infected with P. infestans LC06-44 strain. The leaves were sprayed with 0.5% KPhi five times as treatment, and the leaves were not sprayed with KPhi as control. Two leaves from each of the control and KPhi treated plants were presented. Disease symptoms were recorded at 0, 24, 48, 72 and 96 h time points after infection. (B). Leaves disease severity was calculated from 0 to 96 h after inoculation. Means not sharing a common letter within a graph were significantly different at p < 0.05 according to the Tukey’s test.
