Augmentative Biological Control with Dr. Carlos Bográn

This episode supplements information shared in the past two editions of the GrowerTalks Biosolutions Guide that was released in June 2023 and 2024—a popular grower tool intended to help professional growers stay up to date on the latest research into biosolutions, as well as trialed and tested products and strategies.

 

Many greenhouse owners, growers and IPM managers are moving down the path of softer, more sustainable pest and disease control tactics but continue to use traditional or synthetic chemicals, as well as bio-based products and beneficials or biological control agents. It is this conjunctive approach and the compatibility knowledge required that provides the basis for host Bill Calkins to talk to this episode’s special guest.

 

Dr. Carlos Bográn wrote two well received articles for our first Biosolutions Guide—Using Bioinsecticides in your Greenhouse and Using Bioinsecticides in Conjunction with Biocontrol Agents—and now he joins the podcast to dig much deeper into these topics. Carlos and Bill also discuss high-tech new research findings, different ways to approach pest population management, how the economics of biosolutions has evolved, the current state of the market and new, cutting-edge products becoming available.

Perennial Problem Children

Host Bill Calkins is joined on this Tech On Demand Rewind episode by Darwin Perennials’ General Manager Karl Batschke to take you through some new ways to better produce some of the latest and greatest perennial genetics.  

But he didn’t talk about the easy ones. Instead, Karl addressed some of the more challenging crops and also newer crops that require different cultural and technical regimes. Let’s call  them “Perennial Problem Children”. And like a good guidance counselor, Karl treated each one as an individual and created a custom plan to maximize their potential so you can achieve the results you want—your best crops ever. 

But since Bill had Karl on the hook for 40 minutes, he asked him plenty of questions about the market for perennials, what he was seeing and hearing in his travels pre-2020 and thoughts and predictions for the future, which since this conversation is almost 6 years old … could be what we’re experiencing today!

TESTING NURSERY MEDIA

FROM THE AUGUST 2024 ISSUE OF GROWERTALKS MAGAZINE

WRITTEN BY LYNN GRIFFITH

NARRATED BY BILL CALKINS

 

EXCERPT: Don’t just grab a containerized plant and call that a sample. We like to think of our potting media and fertilizers being perfectly uniform. The truth is they are not. Take about eight to 10 subsamples for each media sample you wish to collect, whether testing in house or at an outside lab. Insert the soil probe from top to bottom of the soil profile. Give the soil probe a twist with your wrist in order to bite into the soil a little bit, sort of a figure 8. This gives you a nice full profile of soil in the probe. If you just stick the soil into the media and pull it out, you won’t get a full tube of soil, especially if the media is dry. Tap each subsample into the bucket.

Critical Chemistries (Recorded Live at Cultivate ’24) with JC Chong

Joining host Bill Calkins live on the show floor at American Hort’s Cultivate ’24 event, Dr. JC Chong dives deep into a few new products from SePRO, recent research findings and why some chemistries offer more benefits than meets the eye.

 

JC is the Technical Development Manager at SePRO following an extensive academic career that includes a BS in Ecology and Evolutionary Biology from the University of Arizona, graduate training at the University of Georgia, post-doctoral training at the University of Florida and a professorship at Clemson University. With almost 20 years in the turf and ornamental industry, he’s now leading SePRO’s ornamental R&D program, delivering innovative solutions to complex problems. He’s also the editor of the popular PestTalks e-newsletter and a frequent contributor to GrowerTalks!

 

In this fun and informational episode, JC and Bill chat about the 2024 season, Thrips parvispinus and what pests and diseases are impacting fall annuals, perennials and holiday crops now before moving into some new products SePRO has introduced in the past year. Bill learns a new word, “symbiont”, and the science behind why a PGR like Topflor is showing visible plant quality benefits in production.

 

JC shares some reasons all growers should consider adding the fungicide Obtego to the toolbox and then shares exactly why SePRO’s new StriCore herbicide is a true breakthrough. It’s not often that we see new active ingredients enter the pre-emergent herbicide market, so it makes sense turf and nursery growers are excited about this one.

 

Be sure to listen all the way to the end because when a podcast is recorded face-to-face, you never know what to expect.

Biosolutions in 2024 (Part Two) ft. Koppert’s Jeremy Webber

In this conversational Tech On Demand podcast two-part episode, host Bill Calkins and his guest Jeremy Webber cover an extremely popular topic these days, biosolutions, in a way that showcases Jeremy’s experience as a grower and as a trusted biocontrols advisor who’s worked with greenhouses of all sizes (growing a wide range of crops from edibles to ornamentals to cannabis and more) to develop and implement biological crop protection programs. As crop team manager at Koppert US, Jeremy works with experienced teams in the field and in the lab and has a tremendous amount of knowledge and experience in modern integrated pest management (IPM) strategies that he shares over the course of two podcast episodes. Be sure to listen to Part One before hitting play on the second part because they go together.

 

Bill and Jeremy start episode one discussing the history of Koppert and its 50+-year history of innovation, as well as the company’s vision for 100% sustainable agriculture, before moving on to why biosolutions are on just about every greenhouse professional’s mind and why more are considering bios every year. Then Bill jumps into some rapid-fire questions based on discussions with growers and some most asked questions—like when to use bios versus conventional pesticides and how costs line up between the two. Throughout the first part, Jeremy considers why he (as a former grower) feels biological approaches are critical for our industry’s future, the importance of trust when partnering with a biosolutions supplier, some examples of success moving the industry forward and why bios are a sustainable strategy for any greenhouse operation.

 

In the second part, Jeremy and Bill dive into some more tactical topics like “gateway” pests to start approaching with biological controls, some favorite predators, unexpected lessons learned from the cannabis side of the industry and why “trials” is possibly not the best word to use when implementing biosolutions on a small scale. Since Jeremy has plenty of greenhouse production experience, Bill asks him for some absolute no-brainer ways that biocontrol strategies can be implemented into any greenhouse immediately—with just-about-guaranteed results.

 

Before closing, Jeremy and Bill chat a bit about what biosolutions in horticulture will look like in the future and why the market is in the right place at the right time. Jeremy also shares a couple quick tips for application and release best practices for biocontrols from his article in the 2024 GrowerTalks Biosolutions Guide (find a link to the digital version below.)

BEST MANAGEMENT PRACTICES FOR UNROOTED CUTTINGS

FROM THE NOVEMBER 2022 ISSUE OF GROWERTALKS MAGAZINE

WRITTEN BY JULIE MARTENS FORNEY

NARRATED BY BILL CALKINS

 

EXCERPT: When delays are excessive, cuttings experience moisture loss, low carbohydrates and possible pathogen development. In some species, ethylene sensitivity increases as carbohydrate levels drop. If cuttings are stressed due to shipping delays, you might see dropping leaves, leaf yellowing or death, dead growing tips or disease.

Success with Poinsettias (Part 2)

You may or may not know that before this podcast, Bill Calkins hosted another one called STEM: Insider Tips for Greenhouse Pros and although the technology was different,  the topics were important and the guests were top-notch. Every now and then, he’ll jump back in time and re-release a STEM episode. In this Tech On Demand Podcast Rewind, we’re wrapping up a 2-part Rewind miniseries on poinsettias. You’ll recognize the guests—now-retired Ball Seed Technical Manager Dr. Will Healy tackled the early stages of poinsettia production in part one and now we’ll hear from Dr. Todd Cavins (former Ball Seed tech guru, now taking his talents to PanAmerican Seed) to take everyone’s favorite seasonal crop to the finish line.

Dr. Todd Cavins is back to finish up our two-part episode on poinsettias. Part 1 kicked off the topic last episode focusing on nutrition, explaining that when it comes to poinsettias, if you have the nutrition right, most of your problems will be greatly reduced. If you haven’t listened to that episode yet, we suggest stopping this one and going back in the archives to Success with Poinsettias (Part 1). If you have listened, great! Todd is going to pick up where Will left off and wrap the topic up by covering tools for height measurement and management, as well as pest monitoring and control strategies. Somewhere around weeks 39 or 40 are critical junctures for this important crop and as Todd tells us, it’s transition and adjustment time and he’s going to share knowledge, tips and tricks to help you make the most of your poinsettia crop, how to use a new graphical tracking tool available from Ball Seed, determining your optimal PGR regime and even some postharvest tricks to maximize sell through at retail. We have a lot to cover this time and Todd certainly lives up to the challenge.

Success with Poinsettias (Part 1)

You may or may not know that before this podcast, Bill Calkins hosted another one called STEM: Insider Tips for Greenhouse Pros and although the technology was different (old school mic, Skype, all sorts of file converting …) the topics were important and the guests were top-notch. Once every couple weeks, we’ll jump back in time and re-release a STEM episode. In this Tech On Demand Podcast Rewind, we’re kicking off a 2-part Rewind miniseries on poinsettias. You’ll recognize the guests—now-retired Ball Seed Technical Manager Dr. Will Healy tackles the early stages of poinsettia production in this episode and hands it off to Dr. Todd Cavins to finish the crop in part two.

 

In this first part, Dr. Healy takes a deep dive into Nutrition. As he explains, when it comes to poinsettias, if you have the nutrition right, most of your problems will be greatly reduced. We start with an overview of the importance of monitoring EC and pH and quickly get into the nitty gritty details of how to approach feeding your crop, the benefits of front-loading fertilizer and even why withholding feed is a bad strategy. Will does a great job explaining how your feeding decisions impact the EC of the crop, as well as how feed leads to excellent or poor crop presentation at retail. If you are wondering what to do if EC starts to creep up, be sure to listen all the way to the end. 

 

We also spend time on pH and what can be gained by staying in the optimal 5.8 to 6.2 range. One of the most applicable parts of this episode is Dr. Healy’s explanation of how to determine crop needs based on the size of leaves on the plant and how you can effectively measure them using your two hands! As we wrap the episode up, Will talks about watering and shares some poinsettia specific watering strategies. As mentioned before, you are going to want to listen this one all the way to the end. And also, share it with your entire poinsettia team because when you’re all on the same page, good things will happen.
