Oil-Based Pesticide Solutions ft. Emily from Kemin Industries
Thursday Oct 31, 2024
Thursday Oct 31, 2024
This episode is all about a cutting-edge approach to insect and disease control—the use of botanical oil-based pesticides within IPM programs. Host Bill Calkins is joined by the director of research and development with the crop technologies division at Kemin Industries, Emily Fuerst. Emily is a highly accomplished scientist with more than 15 years’ experience merging science with agricultural insights to drive innovation across product categories and her passion for insects and expertise in the science of essential oils has led to the launch of a wide range of products responding to grower needs and agriculture challenges.
In this episode, the conversation starts by getting to know Kemin, a family-owned company operating since the 1960s producing science-based ingredients found in the food we eat and supplements we use, as well as nutrition for healthy livestock, poultry, aquaculture and more. Since about 2018, Kemin has been focusing a lot on our industry, bringing innovative solutions to the greenhouse and nursery markets.
As Emily and Bill move into the topic of oil-based biopesticides, you’ll learn why essential oils have the potential to keep pests and diseases under control while minimizing the use of standard chemical pesticides in an IPM program, all supported by scientific trials and success stories. Research and application show these products not only prevent or control greenhouse pests and disease to the same or greater levels compared to conventional chemistries but can be much safer for workers with low to no REI.
Some of Kemin’s leading products such as Romivex DIP (contact miticide and insecticide ideal for cuttings dips), PathoCURB (thyme-oil based fungicide and bactericide) and TetraCURB (miticide-insecticide for TSSM and soft-bodied insects) can not only prevent and solve common greenhouse problems but also extend the effectiveness of conventional chemistries when used in IPM programs and rotations.
It's truly a fun and informative conversation, so be sure to listen all the way to the end!

Tuesday Oct 08, 2024
Syngenta Flowers’ Dr. Jamie Gibson joins host Bill Calkins to discuss just about everything you need to know when producing amazing crops of both Sunfinity Yellow Dark Center (from seeds or plugs) and Sunfinity Double (from unrooted cuttings or liners). This sunflower broke into the industry as a gamechanger not long ago and after multiple years wowing shoppers at retail and in landscape installations, the Syngenta team debuted Double Sunfinity at California Spring Trials this year. Yellow Dark Center and Double are very different crops—from their form (seed vs. vegetative) and how they need to be produced. Dr. Gibson discusses both in detail, including all of the nuances for growers to remember when adding these sunflowers to the mix.
Jamie shares research-based tips and tricks for scheduling, culture and production, positioning for optimal sales during three seasons and even gives a sneak peek into what’s coming next in the Sunfinity lineup. The team at Syngenta has conducted extensive research and trials with Sunfinity and you’ll definitely benefit from all of this work, so be sure to listen all the way to the end of this discussion to set your team up for success.

Growing Cut Flower Dahlias from URC with Dr. Alicain Carlson
Tuesday Oct 01, 2024
Tuesday Oct 01, 2024
Syngenta Flowers’ Dr. Alicain Carlson joins host Bill Calkins to discuss some key components of successful cut flower dahlia programs when starting from unrooted cuttings (URCs). Traditionally, most dahlia crops have been started from tubers, which were dug up and stored each year before replanting. Now, with beautiful dahlias available from URC, many growers are taking advantage of the benefits that come from this form of production. When buying from a reputable supplier, these inputs are virus and disease free with excellent uniformity across the crop, as well as simplified scheduling and potential cost savings. Dr. Carlson digs into the pros and cons of stating from URCs, as well as highlighting some key varieties in the Syngenta Flowers portfolio before moving into culture and production strategies.
Here's what you’ll learn throughout the discussion:
- Propagation tips for rooting into 50- or 105-cell trays
- Importance of long-day lighting in prop
- Rooting hormone trials and recommendations
- Why NOT to pinch young plants
- Winter dahlia production strategies
- Protocols for maximizing flower quality and “double-ness”
- Trial results from temperature research specific to dahlias
- How and when to perform a “hard pinch” after transplant
- Irrigation and nutrition in the field
- Pest and disease management in finished crops
- Postharvest care of dahlias

Augmentative Biological Control with Dr. Carlos Bográn
Wednesday Sep 11, 2024
Wednesday Sep 11, 2024
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
Tuesday Aug 27, 2024
Tuesday Aug 27, 2024
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
Wednesday Jul 31, 2024
Wednesday Jul 31, 2024
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.
