The data presented represent the mortality (assessed at d 5) and colonization (assessed at d 3) of 30 anthracnose-susceptible watermelon (cv Sugar Baby) and cucumber (cv Marketmore) seedlings exposed to various treatments. The assays were repeated a minimum of three times. The only variations between experiments occurred with challenge conditions B and C.
