Sen Extension Assoc (Retired)

Based at the Hudson Valley Research Laboratory, I assess the fruit industry's needs and devise research and extension solutions, focusing primarily on the Hudson Valley, Lake Champlain, and Long Island regions.

Research Focus

The objective of my Extension and research is to work closely with NY's tree and vine industries, collaborating as much as possible with others in Extension and research professionals to help the New York's fruit industries thrive and prosper. This will be done by identifying critical needs in the industry which can have a solution within the realm of research and extension.

Outreach and Extension Focus

We regularly contribute to extension educators' outreach by providing timely, research-based information. We use a variety of appropriate educational media, such as research publications, conferences, grower workshops, newsletters, videos and web sites. Topics include appropriate and profitable planting systems/rootstock combinations for commercial planting, fruit tree pruning principles and practices, grafting apples to more profitable varieties, fruit quality improvement, growth regulator use for fruit quality improvement, and more.
