Perhaps there is such a thing as too much of a good thing. Many farmers in central Pennsylvania would aptly agree to this notion after experiencing above average amounts of rainfall this summer. In fact, rainfall during June and July in central Pennsylvania was more than four inches above average. The high summer temperatures coupled with these increased wet conditions quickly produced ideal habitats for many plant borne diseases. One disease in particular that inflicted dramatic damage upon many local farmers this past summer was late blight. One may recall that this was the plant disease responsible for the Irish Potato Famine back in the mid-nineteenth century. In memory of this historical event, late blight is nothing to take lightly.
