Integrated Pest Management & Resistance Management ft. Corteva’s Broch Martindale

Just in time for warmer, spring temps and the insect pests that seem to come along, Tech On Demand host Bill Calkins caught up with Broch Martindale, the national nursery and strategic account manager at Corteva. The discussion centers on pest management in greenhouses and nurseries but because Broch is a phenomenal educator and “coach” there are plenty of best management practices and training strategies mixed in.

Broch and Bill start with a conversation about XXpire, an insecticide with two active ingredients that provides control for 39 pests—while minimizing phytotoxicity risk and risk to beneficials and pollinators.  Then the topic shifts to IPM and the steps greenhouse teams can take to create a holistic plan that leads to results. Broch then dives into the importance of resistance management, a topic that is becoming more critical each year and one that he has plenty of expertise in and experience to share. You’ll want to listen all the way to the end of this episode and share it with your entire production staff.
