It appears we may have identified a new disease of cucurbits in Alabama. On June 8th we collected samples from plants expressing symptoms of “Cucurbit yellow vine decline” (CYVD) from a small commercial watermelon field in east-central Alabama (Fig. 4). This would be the first report of the disease in the state. We are trying to confirm our diagnosis with the help of USDA scientists in Oklahoma. The disease is caused by the bacterium Serratia marcescens, and is spread by squash bugs. The disease has also been observed on squash and pumpkins, as well as melons in the U.S.
