Weed infestations can begin in propagation then persist through the production cycle. Sanitation practices prevent the spread of weeds into propagation areas, while mulches and pre-emergence herbicides are used to suppress weed seed germination and growth during propagation. Explore best management practices for preventing weed infestations in greenhouse and nursery propagation systems. In this session, growers will learn about mulch products and pre-emergence herbicides that can be safely used in cutting and seedling propagation to reduce labor costs associated with hand weeding.
As experienced growers retire and operations grow more complex, horticulture businesses are asking a critical question: who is coming next?
Learn how your nursery production practices can impact boxwood blight risk and your potential for outbreaks. Whether you’re currently dealing with this disease or working to prevent it, understanding key risk factors is essential for protecting your entire boxwood inventory. Join plant disease expert Jerry Weiland as he examines real-world case studies demonstrating how boxwood blight enters nurseries and spreads via common production activities. This webinar will cover critical factors that influence disease development and spread, including plant size and spacing, cultivar selection, environmental conditions (temperature and moisture), and fungicides. You’ll leave with practical management recommendations and actionable strategies for preventing and controlling boxwood blight in your operation.
HRI recognizes outgoing trustees Leigh Geschwill and Ed Bemis for outstanding service and stewardship
Recent headlines about global insect declines and three billion fewer birds in North America are a bleak reality check about how ineffective our current landscape designs have been at sustaining the plants and animals that sustain us. Such losses are not an option if we wish to continue our current standard of living on Planet Earth. The good news is that none of this is inevitable. Choosing the right plants for our landscapes will not only address the biodiversity crisis but help fight our climate crisis as well. Tallamy will discuss simple steps that each of us can- and must- take to reverse declining biodiversity, why we must change our adversarial relationship with nature to a collaborative one, and why we, ourselves, are nature’s best hope.
The two-spotted cotton leafhopper (also known as cotton jassid) is an emerging pest of growing concern for both cotton and ornamental plant production. This webinar will bring together leading experts to share the latest research and management strategies to help growers identify, monitor, and control this insect.
