I am posting items to the WNC Vegetable and Small Fruit Blog temporarily in the absence of a vegetable agent. Some of you have fields that were recently flooded by the tremendous amount of rain that we have had over the past weekend. The information following comes from Dr. Kelly Ivors and are her most current recommendations as to how to prepare these fields for the crops you plan to plant in particular tomatoes and peppers.
"Our NCSU labs can test water for Phytophthora (that isn't the problem), but the water samples will be variable and very hard to determine what was in the exact flood waters that each field was exposed to when the flooding occurred. Samples would have needed to be taken during the flooding. Flooding also carries debris and anything else that is water soluble or water 'floatable'. You just have to assume that there is a increased potential that Pythium and possibly Phytophthora could have been introduced, or other pathogens that are water dispersable. My chapter on oomycetes in the new APS Press book "Waterborne Plant Pathogens" (IN PRESS!) goes over this variability in detail.
