- Dickeya sp., an aggressive form of Black leg, has been confirmed on potato in New Jersey in 2016. Symptoms of Dickeya infection look similar to Black leg infection and can cause significant rot above ground (stems and foliage) and below ground (tubers). All potato growers should scout on a regular basis and report any suspect plants or fields.
- There have been no new reports of cucurbit downy mildew.
- With the cool, prolonged wet weather, basil downy mildew may become active in greenhouses or high tunnels that have been closed up to retain heat. Appropriate venting to keep relative humidity low and leaf wetness to a minimum is critically important to keep the pathogen from sporulating and spreading rapidly.
