The Temperate Tree Fruit and Vegetable Research Unit conducts research in three areas: Biology and management of pests and pathogens of tree fruits, biology and management of pests and pathogens of potatoes, and potato germplasm improvement. We also contribute to national IR-4 efforts to provide data needed for regulatory approval of pesticides in specialty and minor use crops.
We conduct research on biology and management of tree fruit pests, including fruit flies, codling moth, pear psylla, northern giant hornet, and leafhopper vectors of the X-disease pathogen. Research areas include plant-insect interactions, ecology, biological control, chemical ecology, physiology, and genetics.
We conduct research on biology and management of insects that vector pathogens of potato and other vegetable crops. Top left photo shows a parasitoid emerging from a beet leafhopper. The bottom right photo shows zebra chip symptoms in potato tubers.
We strive to develop new potato cultivars with superior pest and disease resistance, enhanced amounts of phytonutrients, and better quality that enhance food security, sustainability and protect profitability and jobs.
The mission of the IR-4 Project is to facilitate regulatory approval of sustainable pest management technology for specialty crops and specialty uses to promote public well-being.

The mission of the Temperate Tree Fruit and Vegetable Research Unit is to improve basic and applied information needed for the development of safe and environmentally sustainable methods for management of arthropod pests and plant pathogens of temperate tree fruits and vegetables, and to develop new potato varieties with improved pest and disease resistance, quality, and enhanced phytonutrient content.
