The purpose of the presented investigations was to determine uniform laboratory methods of evaluating horizontal resistance of tomatoes to late blight. It was found that the best tests were infecting whole plants at the 5-leaf stage and infecting leaves removed from the middle part of the shoot. The best method of testing the resistance of fruit to infection was instilling a suspension of spores on the calyx with the sepals left in place
