Since the 1970’s Don Huber, an Emeritus Professor of Plant Pathology at Perdue University, has been studying the environmental and human effects of “glyphosate”, the primary broad-spectrum systemic herbicide used to kill weeds on more than 80% of American farms. He discusses with Iowa corn and soy farmers the short and long term harmful effects of the pesticides, herbicides and fungicides they use and they listen intensely.
He is accompanied by Iowan Bob Streit who graduated with degrees in Plant Pathology, Pest Management, and Agronomy.
