Many growers throughout the world have been battling large yield losses due to a disease caused by the fungus Sclerotinia sclerotiorum. With worldwide distribution and a wide host range, gaining basic understanding of Sclerotinia sclerotiorum will prove beneficial when attempting to forecast disease outbreaks caused by the pathogen. The variability in host creates large variation in infection sites, sampling timing, favorable environmental conditions, and effective management strategies. This is a review of current literature covering the variables associated with the disease and its host species utilized in scouting and preventing further epidemics. The beginning literature covers the history and importance of the disease. It is followed by literature explaining the signs, symptoms, hosts and locations, and the lifecycle of Sclerotinia sclerotiorum. To conclude, literature was compiled for the best ways to scout and assess the damage by the fungal pathogen and which management practices would be most effective. No management strategy is 100% effective, integrating multiple approaches of cultural, chemical, and biological will be the best management practices to prevent diseases caused by Sclerotinia sclerotiorum.
