Plant dips, the role of nutrition, advancements in biocontrols and related topics are included to help improve pest control reducing dependence on traditional chemistry.

9:45-10:30 Meg McGrath – Title: The Lowdown in Basil Downy Mildew
While there have been substantial advancements in management of downy mildew in basil, especially for greenhouse crops, since this disease was first detected in the U.S. in 2007, it continues to be one of the most important diseases in herb crops. Meg will cover new management tools plus changes detected recently in the pathogen affecting resistant varieties, and she will provide recommendations on how best to achieve effective control. Her webpage on basil downy mildew includes a section focused on management in greenhouses: https://www.vegetables.cornell.edu/pest-management/disease-factsheets/basil-downy-mildew/.

PM Program

1:15pm-1:25: Presentation from Mike Mitchell on New York State Flower Industries

1:25-2:15pm John Sanderson – Title: How to handle and release biocontrol agents for best results

How can you ensure that the beneficials you’ve purchased will work their best? Learn how to avoid making mistakes about how you release and manage beneficial organisms to maximize the cost-effectiveness of your investment. Learn best practices for receiving shipments and storing a variety of beneficials (and which ones should not be stored), and how to release them into your greenhouse for best results.

2:15-3:00pm Judson Reid – Title: Biocontrols in greenhouse vegetables and ornamentals

Growing vegetable transplants and flowers together is a spatial necessity for most growers, but is mixing the two a good idea? Are there control options that can be used in both categories? Biological controls such as predatory insects and mites can reduce pest pressure and insecticide use in flowers and vegetables. In this session we will cover real life examples of how to implement biocontrols in mixed cropping systems, cost and effective species/techniques.
