Tech On Demand: Root, Stem and Crown Rot Diseases with Aaron Palmateer
In this episode of Tech On Demand brought to you by GrowerTalks, host Bill Calkins is joined by Aaron Palmateer, Senior Technical Representative with Bayer Ornamentals, to talk about root, stem and crown rot diseases. Because some of the diseases discussed occur below the soil and out of sight, detection is extremely critical to avoid devastating effects to the crop. The earlier symptoms are detected the better - that’s how this episode begins. Next, Aaron moves to an overview of the major pathogens impacting root, stem and crown and exactly how they cause disease. He goes in depth on the Big Four – Pythium, Phytophthora, Rhizoctonia and Fusarium – but also discusses less-common pathogens and fungi. This episode concludes with a review of treatment options and rotation suggestions.
Be sure to listen all the way to the end of this episode to learn about a new resource available from Bayer, a user-friendly Spanish language pest identification guide that’s sure to be a critical tool for all greenhouse operations.

Tech On Demand: Foliar Diseases of Ornamental Plants
In this episode of Tech On Demand brought to you by GrowerTalks, host Bill Calkins is joined by Aaron Palmateer, Senior Technical Representative with Bayer Ornamentals, to talk about foliar disease on greenhouse crops. Leaf spot disease management must be a top priority for all greenhouse professionals and Aaron explains why, as well as comparing the importance of yield to farmers with quality for greenhouse growers. After setting the stage for this episode’s discussion, the conversation moves to the importance of diagnostics and then a deep dive into how exactly disease happens and a review of the “disease triangle” with a twist. The differences between fungal and bacterial pathogens are detailed before Aaron tackles best practices to avoid them. This episode concludes with a review of treatment options and how to avoid resistance.

Tech On Demand: At Risk Crops - Overview
This episode kicks off a miniseries on At Risk Crops. For a high-level overview of this topic, we’re joined by Dr. Will Healy, senior technical manager for Ball Horticultural Company. To start off our look at At Risk Crops, Dr. Healy digs into ways to manage the Disease Triangle – Pathogen, Host and Environment – and overall strategies to use when producing crops with inherent challenges. Continuous management of the disease triangle, throughout the entire production process, is required to ensure crop success.

Tech On Demand: Holding & Delaying Greenhouse Crops
Although this season is an anomaly, the first time North America has experienced pandemic-related quarantines and sheltering, holding crops due to market challenges like weather impact growers more often than not. Today, we catch up with three experts covering a wide range of greenhouse crops from a technical and cultural perspective to learn strategies greenhouse professionals can use when product can’t be shipped on time. What crops respond well to holding and delaying strategies from cutting back to temperature manipulation and chemicals to lighting? How can you best make those kinds of decisions? What data do we have to determine how to treat specific crops? Are there any that you absolutely should not hold in certain ways? We tackle all of this and much more for seed annuals, vegetative annuals and perennials with PanAmerican Seed's Jerry Gorchels, Gary Vollmer from Ball FloraPlant and Selecta One and Chris Fifo with Darwin Perennials and Kieft Seed. The goal is to keep annual and perennial crops alive and saleable longer.

Tech On Demand: Greenhouse Sanitation
Our Tech On Demand topic du jour is Greenhouse Sanitation. This time, we’re joined by Dr. Todd Cavins. Todd’s one of the technical services experts at Ball Seed and has been helping professional growers solve greenhouse production challenges for more than ten years in the field and before that was a professor at Oklahoma State University. You may have seen the hashtag #startcleanstayclean in hort posts recently. We all know it’s true. But does your greenhouse really have a sanitation plan? You don’t have to answer that, but you do have to listen all the way to the end of this episode because Todd covers a lot. From how growers (especially managers) traffic pests around a greenhouse to best practices for keeping greenhouses clean, Todd takes us from spring cleanup through crop production in all stages to help determine where problems lie and most importantly, how to clean them up.
