Vegetables and Berries

Studies on how high tunnel systems can help manage disease, pests, and cold weather while extending the Minnesota growing season are underway at research sites throughout Minnesota.

Landscape Plants

U of M researchers are providing new proven varieties of plants for Minnesota nurseries to grow. These new varieties are often pest resistant, well adapted, and tested to survive Minnesota's Zone 3 and 4 conditions.

Grapes and Apples

From Honeycrisp to SweeTango® University researchers have been instrumental in growing Minnesota's apple industry. New cold-hardy grape varieties developed at the University have initiated the rapid growth of Minnesota's wine industry.

Since its arrival in 2012, the spotted wing drosophila (SWD) has been one of the most damaging invasive species in Minnesota agriculture. Bill Hutchison and his team are exploring several management practices to help Minnesota small fruit growers deal with this devastating threat.

Honey bees play a keystone role in the productivity of agriculture and the beauty of our world by pollinating fruits, vegetables, nuts and flowers. Recently, Marla Spivak and her team have been exploring how honey bees keep themselves healthy through social immunity - including propolis envelopes.

Dutch elm disease (DED) remains the most devastating invasive tree disease to affect Minnesota. Despite extensive research on DED, it remains unclear what mechanisms allow certain elms to be resistant while others are susceptible.
