Oregon Tilth documentary - Part 11

Here the video begins with stock footage of Nature’s produce selections. Later in the video, a speaker identified as Mary, talks about her work with a disease known as potato-early dying (PED). Large losses of potato yields are associated with the disease and eradication is difficult. According to Mary, a three year period of biological control is best when destroying this disease. Unfortunately this is not a cost effective method and many turn to fumigation to aid eradication.
