With an emphasis on integrated pest management (IPM) methods and best management practices, the University of Maryland Extension Commercial Ornamental Horticulture Team supports a strong nursery and landscape industry. We publish a weekly IPM alert from late March through October to inform nursery growers and commercial horticulture professionals of potential problems to help them monitor their crops and landscapes more closely to prevent problems from occurring. We conduct applied research trials to provide growers with effective pest control options and methods for implementing biological control programs in their operations. We organize various educational programs, ranging from hands-on IPM Scout training to biological control options, throughout the year.
