Research and extension efforts on pome fruit, small fruit, grape and  onion has been to study the efficacy of newly developed pest management tools on newly emerging invasive insects and native insect pest complex. Employing them in a cost-effective, environmentally sound approach provides fruit growers with the knowledge to improve insect pest management strategies. Pest management at  Jentsch Lab Blog Site

As Plant Pathologist at Cornell University’s Hudson Valley Laboratory in Highland, NY, Dr. Rosenberger’s research program focused on finding immediate solutions to disease problems on tree fruits. Field tests were conducted each year to evaluate new fungicides and management strategies for apple diseases. Fungicides were evaluated for effectiveness against apple scab, powdery mildew, rust diseases, sooty blotch, flyspeck, black rot, and bitter rot. Research reports and outreach can be found on Rosenberger Blog Site.
