<p>Oomycetes pathogens causes devastating crop diseases worldwide. In this study, we compared mycelium growth of 7 Oomycetes species using the calculated area (CA) method obtained by perpendicular diameter of colony and measured area (MA) method. Results revealed a significant difference between Oomycetes species inhibition ratio using CA and MA, at lower mefenoxam concentrations. The interval of variation between MA/CA methods was variable according to Oomycetes specie. The largest interval (0.01-1000 μg/ml) was detected with <em>Pythium aphanidermatum</em> and <em>Phytopythium mercuriale</em>. The second interval (0.01-100 μg/ml) was determined by <em>Phytophthora cryptogea</em>, <em>P. aphanidermatum</em>, <em>P. ultimum</em> and <em>P. mercuriale</em>. An interval ranged from 0.01μg/ml to 31.6μg/ml was recorded with <em>P. cryptogea</em> and <em>Phytopythium</em> <em>vexans</em>. An interval from 0.01 μg/ml to 10μg/ml was determined with <em>Pythium dissotocum</em> and <em>P. vexans</em>; while the shortest interval (0.01-1μg/ml) was noted with <em>P. nicotianae</em>. In addition, present findings recorded a difference in Pearson’s correlation index between growth factors (medium, evaluation dates, mefenoxam concentration) and Oomycetes mycelium growth using MA and CA methods. A statistical significance difference (P&lt;0.05), weas noted more in case MA method and was more expressed in case of CA method.</p>
