Managing Impatiens Downy Mildew with Variety Selection and Production Practices
Welcome to the American Floral Endowment's Grow Pro Webinar Series! Throughout this series, our nationally recognized researchers, hosts, and speakers will offer ‘how-to’ advice based on AFE-funded and other research projects to help the industry navigate through these ever-changing growing challenges. The webinar topics are current and offer long-term opportunities for growers to focus on increased profit, greater sustainability, and improved labor efficiency. Each session includes a presentation and interactive Q&A. To see the full series calendar visit endowment.org/GrowPro.

The September 14th session of our series focuses on downy mildew.

The September session is sponsored by PanAmerican Seed Company and Syngenta.

Impatiens was once one of the most popular bedding plants until Impatiens Downy Mildew (IDM) devastated landscape plantings around the world. Plants often looked good in production but died once planted in the landscape. After a decade of breeding and technology, impatiens are back with two new series offering a high degree of resistance to IDM. Margery Daughtrey, plant pathologist at Cornell University, will discuss the attributes of Beacon (PanAmerican Seed) and Imara XDR (Syngenta Flowers) series and share practical tips to optimize performance of these plants from propagation to planting in the landscape. You will learn that using protectant fungicides during production is a good idea, even when impatiens are highly resistant to downy mildew.
