Safely Managing Whitefly (and more) on Poinsettias with Broch Martindale

Corteva’s technical guru, flower grower and greenhouse and nursery “coach” Broch Martindale is back on the podcast to share strategies for controlling and preventing some of the more common pest and disease challenges you might face in poinsettia production—like whiteflies and powdery mildew—using chemistries like XXpire, Floxcor and Eagle.

Over the course of this episode, Broch and host Bill Calkins discuss safely using chemistries in rotation and what chemistries are appropriate for poinsettias late in production (when bracts are in color), as well as specific active ingredients that have been successfully trialed and tested to tackle common but challenging greenhouse pests. Throughout the podcast, Broch offers tips and tricks he’s turned to over the years producing crops and working with growers to manage and prevent pests when producing everyone’s favorite holiday crop.

Be sure to read Broch’s article KEEPING POINSETTIAS MERRY AND BRIGHT in the May 2025 issue of GrowerTalks magazine for even more on this topic.
