Comparisons of Phytophthora infestans strains HZ02 and DL04: (a) culture morphology after 8 days of incubation, (b) mycelial growth over 4, 6, and 8 days, (c) mycelial weight, and (d) sporangia count per unit of mycelial weight. Error bars represent standard deviations. Asterisks (**) indicate a significant difference between the strains (P < 0.01)
