This episode’s guest should be quite familiar by now as he’s joined host Bill Calkins multiple times to cover a range of topics related to IPM from a pest- and disease-specific angle, as well as seasonal controls and prevention strategies and even weed management.

Broch Martindale is the National Nursery & Greenhouse Strategic Account Manager at Corteva and downloads of his episodes are always strong proving that loyal listeners and many others across the industry are well aware of his ability to share detailed research-based cultural information blended with real-world greenhouse and nursery production experience. Check out the show notes for links to all of Broch’s 2025 episodes covering a range of topics.

This time, Bill and Broch look back on 2025—spring, summer and fall production—to highlight pests and disease that were particularly troublesome over the past 12 months, as well as products and approaches growers used to effectively go to battle before and after symptoms emerged. They talk spring pests like aphids and thrips that were prevalent coast to coast, mum diseases and issues due to warmer-than-average weather and poinsettia growers facing pathogens and insect/mite pests.

Broch also went into detail about how investments in research and development by companies like Corteva drive product effectiveness, even when active ingredients might look alike on labels. Did you know that particle size can dictate the amount of active ingredient actually getting to where it needs to be for full mortality—which, in turn, reduces the risk of resistance?
