WHAT DOES “COMPATIBILITY” MEAN?
FROM THE FEBRUARY 2024 ISSUE OF GROWERTALKS MAGAZINE
WRITTEN BY DR. RAYMOND A. CLOYD
NARRATED BY BILL CALKINS
EXCERPT: … integrating BCAs and pesticides is complex due to the various direct and/or indirect effects that pesticides may have on BCAs. For instance, any delay in the population growth of BCAs by pesticides (and even fungicides) can substantially affect the ability of BCAs to manage pest populations below economically plant-damaging levels. Another factor to consider is that combining BCAs with pesticides not only has to effectively manage pest populations, but also has to be cost-effective. Finally, we need to stop using the term “compatibility.”

Tip Atrophy: Triggers & Solutions
Thursday Feb 01, 2024
Thursday Feb 01, 2024
Something some of you might struggle with early in production is tip atrophy, often called tip abortion. This is when you see symptoms during propagation, often on calibrachoa or petunia, where it looks like the cuttings were accidentally pinched—but you know they weren’t. Poor rooting, stunted growth and strappy foliage can also cause you to wonder what the heck is going on? To answer that question, we turn to Dr. Will Healy.
As Will explains, this issue can be triggered by a handful of different occurrences in propagation and doesn’t always affect the entire crop. He starts by explaining that tip atrophy occurs in a range of different greenhouse crops in every season but is most often experienced with petunia and calibrachoa in the spring and pansy in the fall. It can be pervasive across entire crops or random, making it especially frustrating. Usually considered a symptom of nutrient deficiency, Will explains that tip abortion or atrophy is nutritional but there are certain processes to understand.
Will runs through the need for micronutrients, especially boron, calcium and copper in a tip atrophy prevention strategy and exactly what levels to aim for when supplementing. The final piece to this puzzle is being aware of potential trigger events. High relative humidity, low light, poor root growth, wet growing points, high soil pH, low transpiration, nutrient leaching and more can lead to tip atrophy.
By the end of this presentation, you and your team will be in a much better position to avoid tip atrophy and tip abortion in your greenhouse production.

AVOIDING TAX AUDITS
FROM THE JUNE 2023 ISSUE OF GROWERTALKS MAGAZINE
WRITTEN BY MARK E. BATTERSBY
NARRATED BY BILL CALKINS
EXCERPT: Today, the IRS enforces the tax law in a number of ways, including the increasingly more common correspondence (examination by mail) audits and the dreaded field (face-to-face audit) examinations. The result is that many businesses are being scrutinized far more often than the numbers indicate.

Achieving Uniformity in Canna Production
Wednesday Jan 24, 2024
Wednesday Jan 24, 2024
As we’ve discussed in other Tech On Demand videos and podcasts, the key to successfully producing high quality crops often starts at the very beginning. How you and your team approach the earliest stages of germination and propagation sets the stage for uniformity down the line. We’re pleased to welcome back frequent guest Dr. Will Healy who continues to think about ways to share his knowledge and decades of experience working with growers of all shapes and sizes. This time, he's here to focus on canna, which can be a tricky one.
YOU WANT TO WATCH THIS VIDEO ALL THE WAY TO THE END, BECAUSE THERE ARE SOME CRITIAL TOPICS COVERED RELATED TO PGRs AND NUTRITION SPECIFIC TO CANNA!
Will begins by explaining the germination process, defining terms and talking about the unique laser drilling technology that allows moisture to penetrate really hard canna seeds. After establishing the importance of proper moisture management and temperature control for tropical crops like canna, he digs deeper into flat filling and seeding best practices. With canna, the trick is BURYING THE SEEDS so they don’t rise to the surface after irrigation. Will offers three options for achieving this on the seeding line.
Before wrapping up, Will spends time on growth regulator selection specific to canna, because as a monocot there are some chemicals to avoid. Nutrition is also covered, because canna respond best to certain formulations.

How you and your team approach the earliest stages of germination and propagation sets the stage for uniformity down the line. We’re pleased to welcome back frequent guest Dr. Will Healy, who continues to think about ways to share his knowledge and decades of experience working with growers of all shapes and sizes. This time, he's here to focus on seed-raised begonias
Will begins by explaining the germination process, defining terms and talking about the importance of melting the coating on pelleted seeds. After establishing the importance of proper moisture management to melt pellets effectively, he digs deeper into flat filling and seeding best practices including properly centering the seed in each cell and not burying them.
Then the discussion turns to why you should treat begonias like unrooted cuttings in the after germination—they’re a monocot, with root clusters instead of a taproot. As a tropical plant, Will reminds us that cold water in germination is not ideal and tempered water should be used. Lighting is also recommended—immediately after trays leave the water tunnel. You’ll also hear protocols for irrigation management and nutrition to help get begonias off to a strong start. The discussion wraps up with quick looks at other begonia species often started from seed, like tuberous, interspecific and boliviensis types.

TWO TOBAMOVIRUSES TO KEEP AN EYE OUT FOR
FROM THE FEBRUARY 2023 ISSUE OF GROWERTALKS MAGAZINE
WRITTEN BY DR. ANN CHASE & DR. MARGERY DAUGHTREY
NARRATED BY BILL CALKINS
EXCERPT: Virus symptoms are notoriously hard to identify just by looking. They can be mimicked by genetic variegation, or by certain other diseases or disorders, even spray injury—especially from overspray or drift from herbicides. One virus disease can easily be mistaken for another.
Tobacco mosaic virus (TMV) and tomato mosaic virus (ToMV) are two very closely related viruses that you may encounter on many different greenhouse crops. Identifying ToMV or TMV may start by looking for mottling or mosaic in leaves, yellowing or browning of veins, leaf strapping, stunting or dieback of plants.

THE RISE OF VERTICAL FARMING
FROM THE FEBRUARY 2023 ISSUE OF INSIDE GROWER MAGAZINE
WRITTEN BY DANIEL PILSWORTH
NARRATED BY BILL CALKINS
EXCERPT: The sky is the limit: In 1999, Columbia professor Dickson Despommier used the term “vertical farming” to describe a system of agriculture in which crops are grown indoors on vertically stacked platforms. His students imagined skyscrapers with lush greens, bursting from the sides of city buildings and providing hyper-local produce to dense urban centers.
In the two decades since then, vertical farming has grown up in unexpected—yet promising—ways. In fact, according to the most recent P&S Intelligence report, the total vertical farming market size in 2021 was $3.98 billion and this number is expected to grow 25.2% annually to reach $30.2 billion by 2030.

REHYDRATING UNROOTED CUTTINGS
FROM THE JANUARY 2024 ISSUE OF GROWERTALKS MAGAZINE
WRITTEN AND NARRATED BY BILL CALKINS
EXCERPT:
Fact: Dehydrated cuttings root non-uniformly. This means in the earliest stages, unless rehydration strategies are in place, you run the risk of getting off to a weak start. Poor moisture management at the beginning of the process will cause problems throughout production.
In a recent Tech On Demand video, Ball technical managers Dr. Will Healy (now retired) and Dr. Nathan Jahnke shared tips and tricks for choosing the best rehydration methods, based on trials and research. This article summarizes their key points in an effort to help you make the best decisions when cuttings land on your loading dock.

Will begins by explaining the germination process, defining terms and talking about the importance of melting the coating on pelleted seeds (like petunias). After establishing the importance of proper moisture management melt pellets effectively, he digs deeper into flat filling and seeding best practices including properly centering the seed in each cell and NOT BURYING PETUNIA SEED, which can be more challenging than it sounds. Then the discussion turns to building a strong root system and avoiding “root running” or failure to root. As cotyledons begin to emerge, attention must be paid to the goal of achieving uniform petunia stands and again, it comes back to irrigation to prevent drying. By day 8 in the germination process, your petunias should be off to a strong start, setting the crop up for success.
