Vegetable Disease Briefs – 5/25/16

  • No new reports of Late blight in the region this past week.
  • Cucurbit downy mildew has been reported on cucumber as far north as south-central Georgia.
  • Septoria leaf spot has been reported in Parsley.
  • Anthracnose fruit rot is being reported in strawberry.
  • Botrytis is being reported in greenhouse tomatoes and in strawberries fields. The weather the past few weeks has been ideal for its development in a multitude of crops. Growers need to scout on a regular basis and incorporate Botrytis specific fungicides into their weekly maintenance sprays as long as the current weather pattern remains the same.
  • Transplant health – transplants that have yet to be put in the field and that are showing signs of stress via the lack of fertility and water to keep them to size can become predisposed to a multiple of opportunistic fungal and bacterial pathogens. Growers need to pay close attention to and adjust fertility and watering programs on a daily basis and consider preventative fungicide applications.
