Minimal inhibitory concentration (MIC) values of oxathiapiprolin in preventive and curative application against late blight induced by Israeli isolates of <i>Phytophthora infestans</i>, in detached tomato leaves.

A- Detached leaflets were treated with oxathiapiprolin of 0.00001–10 ppm active ingredient (ai) on lower leaf surface and thereafter spray-inoculated with each of 106 isolates of P. infestans. B- Detached leaflets were first inoculated with each of 90 isolates of P. infestans on lower leaf surface and at 1 day after inoculation were treated with oxathiapiprolin of 0.00001–10 ppm ai. Percent of leaf area showing sporulation of the pathogen was recorded at 7 days post-inoculation (dpi).
