Beneficial Nematodes: Where Are We?

Date: Thursday, December 13, 2018
Time: 1:00 PM Eastern/12:00 PM Central

Beneficial nematodes are gaining in popularity as a way to naturally control many pests of greenhouse crops, including western flower thrips, fungus gnats and shore fly. But all nematodes are not created equal! Production methods vary, and the quality of the nematode you put out in your crop can impact the pest control results you see.

In this free GrowerTalks webinar, our guest experts, biocontrol expert Suzanne “Buglady” Wainwright, and Julie Graesch, a scientist with BASF, will discuss, in-depth and objectively, the various ways nematodes are produced, giving the pros and cons of each based on their research and experience. In addition, you’ll learn:

- The commercially available nematode species
- Their biology and target pests
- Available formulations
- How to get the most out of your nematode applications
- What’s new in research

It promises to be a fabulous hour-long webinar!

Healthy water: Removing pesticides and supplying oxygen to plant roots

Date: Tuesday, November 13, 2018

Are your crops suffering from chronic exposure to chemical residues in your water? Are your plants’ roots being starved of oxygen? This free GrowerTalks webinar will explore both aspects of water quality. Our expert, professor Paul Fisher of the University of Florida, works closely with industry and university colleagues in two projects called the Floriculture Research Alliance (floriculturealliance.org) and CleanWater3 (cleanwater3.org). He often partners with growers to deal with water quality issues.

In this webinar, Dr. Fisher share the latest research on:

- Pesticides and plant growth regulators, which can accumulate in recirculated irrigation water and affect subsequent crops. Paul will discuss granular activated carbon filters and other technologies to remove agrichemicals

- Understand the role of dissolved oxygen in irrigation water and the root zone. Paul will discuss how oxygen levels change in water, various technologies to increase dissolved oxygen, and the importance of irrigation and container substrate on oxygen supply to roots

New Research, New Innovation in Botrytis Management

Date: Tuesday, October 16, 2018

Botrytis is widely considered to be one of the costliest diseases in greenhouse ornamental production—and deservedly so, since it’s also known as a high-risk pathogen for its potential to develop fungicide resistance. It’s a challenge many growers encounter when their trusted fungicides stop performing like they used to.

In this free webinar, featuring guest experts Dr. Janna Beckerman and Dr. Aaron Palmateer, you will garner actionable insights on:

- The latest research in Botrytis management
- Topline results from research trials on fungicide efficacy for Botrytis control
- Details on the new fungicide Broadform, by Bayer, a new resistance management tool and specialized solution for control of Botrytis and other key bedding plant pathogens, including Alternaria, Anthracnose Myrothecium, powdery mildew and Septoria.

As a bonus, all webinar participants are registered for a chance to win one of four free bottles of Broadform! Click here for the official rules.

Don’t Balk at Plant Diseases—Strike Them Out!

Date: Wednesday, April 11, 2018

Baseball isn’t just a metaphor for life, but for disease management, too. In baseball, three strikes and you’re out. With diseases, if you take care of three key areas—culture, identification and solutions—you’ll strike out diseases.

On Wednesday, April 11, we’re kicking off the GrowerTalks webinar series “season opener” with a primer on four big-league diseases—pythium, botrytis, leaf spots and anthracnose—you need to be on the lookout for in your greenhouse and nursery. Our “coach,” Dr. Janna Beckerman of Purdue University, will give you the “three strikes” playbook—culture, ID and control methods—for each of these diseases.
