May 2800:45:51Tap to summarizeDr. Janna Beckerman from Envu joins host Bill Calkins for this episode of the Tech On Demand podcast, brought to you by GrowerTalks magazine. Janna is here to discuss a topic that she’s very passionate about and for good reason—resistance management could be the most critical component to greenhouse production IF we want to grow healthy crops in the future and maintain a toolbox of effective chemical and biological solutions. That’s tremendously oversimplifying things but throughout this episode, Dr. Beckerman will help make sense of it all and leave you with an excellent rotation to use against multiple, common greenhouse pests. Janna Beckerman is an ornamentals technical specialist at Envu, and part of their Green Services Team. Prior to Envu, she worked at Purdue University and the University of Minnesota as a professor of plant pathology for almost 25 years. Janna continues to focus on developing environmentally sound pest management strategies that are economically feasible for growers and pest managers of specialty crops and is now excited to also focus on insect and weed management.
