New York poinsettia growers face unique challenges during the growing season. This year, resistant pests tested their skills. Thankfully, Cornell University stepped in, offering research-backed solutions that saved crops just in time for Poinsettia cultivation for the holiday season.
Poinsettia Cultivation: How Cornell Helped Control Resistant Mites
Poinsettias are iconic holiday flowers, but they’re also picky about their environment. This year, growers in New York battled stubborn Lewis mites that resisted standard miticides. Mark Van Bourgondien, co-owner of CJ Van Bourgondien Wholesale Greenhouses, noticed unusual white flecks on his plants. His usual pest control methods failed, putting the season’s crop at risk.
Cornell’s Long Island Horticultural Research and Extension Center (LIHREC) quickly stepped in. Entomology specialist Dan Gilrein collected samples from affected greenhouses. After confirming the mites’ resistance, he recommended a new treatment plan. Growers followed his advice, successfully controlling the infestation and saving their crops.
Poinsettia Cultivation’s Economic Impact in New York
Growing poinsettias isn’t just about spreading holiday cheer—it keeps businesses afloat. New York’s greenhouse industry depends on this seasonal crop. Companies like Emma’s Garden Growers rely on poinsettia sales to maintain year-round employment for staff.
Co-owner Eric Keil highlighted the critical role of Cornell’s research and support. “Without LIHREC, we’d struggle to survive,” he shared. The research centre continuously collaborates with growers, testing new pest-control methods and offering expert advice.
Beyond battling pests, the growers take pride in their work. The sight of perfectly lined-up poinsettias in full bloom is rewarding, even after a tough season. For these dedicated growers, a successful harvest means not only beautiful holiday displays but also thriving businesses.
