New photo gallery: Anthracnose in cucurbit crops

Anthracnose occurs occasionally in cucurbit crops in the Northeast.  Following pictures of cucumber leaves taken on 7 and 15 August in 2014 show how symptoms can change in appearance in just one week.  The circular leaf spots are initially water-soaked, then become yellow to tan.  Round, black, sunken spots can develop on fruit.  On fruit spots the pathogen produces diagnostic salmon-colored spores under moist conditions.
