The Commercial Horticulture program offers training opportunities for landscapers, garden center retailers and growers. We are a member of Hudson Valley Horticulture, a seven-county regional team serving the needs of green industry professionals in the lower Hudson valley. Pesticide certification, arborist training, greenhouse management and more are some of the programs offered by the group.


Pesticide Certification
If you apply pesticides, including weed killers, weed-and-feed products, insecticides, fungicides or tick control products for hire, you or someone in your company must be a Certified Pesticide Applicator. The certification program is run by the New York State Department of Environmental Conservation (NYS DEC). Cornell Cooperative Extension of Putnam County provides Pesticide Licensing Pre-exam Training and hosts the Pesticide Licensing Exam twice a year at Hilltop Hanover Farm in Yorktown, NY.Directions to Hilltop Hanover Farm

Alert: Emerald Ash Borer found in New York State.

The Emerald Ash Borer, which is responsible for the death of more than 50 million ash trees since its discovery in Michigan in 2002, has been found in western New York, in Cattaraugus County. The emerald ash borer (Agrilus planipennis), an Asian beetle, infests and kills North American ash species (Fraxinus sp.) including green, white, black and blue ash. All native ash trees are susceptible.

Signs of infection include tree canopy dieback, yellowing and browning of leaves, and profuse suckering from base of tree. Most trees die within 2 to 4 years of becoming infested.

Adults are roughly 3/8 to 5/8 inch long with metallic green wing covers and a coppery red or purple abdomen. Adults leave distinctive D-shaped exit holes in the outer bark of the branches and the trunk. They may be present from late May through early September but are most common in June and July.

What can be done? Link to the websites shown below for details about the insect, its life cycle and its impact on trees. Most importantly, because most long-distance movement of EAB has been directly traced to ash firewood or ash nursery stock, Do not move firewood! When travelling, purchase or cut firewood from the same general location where you plan to use it. When camping or at a cabin, do not take any leftover firewood home with you.
