    Rotating from Resistance to Results ft. Envu’s Dr. Janna Beckerman

    Dr. 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.   Resources Envu Ornamentals Envu Ornamentals Team Altus insecticide Aria insecticide Kontos insecticide Podcast: The ABCs of Foliar Disease in Greenhouse & Nursery Crops Podcast: Preemergence Weed Control for Greenhouses & Nurseries

    Nick's Newsletter Tip (Week 21): Garden Mum Prep & Production Basics

    Hey everyone—Nick Flax with the Ball Seed Tech Team here! Every mum season, I tend to get the same core questions from growers—especially as material starts arriving and hitting the transplant line and moving into production—so today I want to try to head some of those questions off before they turn into headaches. This week, I’ll walk through a few topics that I get questions on most often: propagation, premature budding, and disease pressure. I’ll also point you toward some additional resources if you want to go a little further down the rabbit-hole on any of these topics.
