William Hutchison and his team are working on developing integrated pest management systems to assist with the control of japanese beetles in the specialty crop industry. 

Matt Clark and his team conducting research on an emerging global problem called Grapevine Trunk Disease with the aim of identifying the pathogens, determining their impact, biology and ecology and developing necessary management recommendations for vineyards.

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.

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.

Abdennour Abbas and his team have been working on a faster, more accurate and less expensive tool to detect oak wilt fungus in the field. Their new tool combines three technologies: one to extract the fungus from wood chips, one to extract DNA and one to analyze the DNA.

Minnesota has seen rapid growth in its wine industry, particularly in the past decade. To continue this growth, vineyard owners are in constant need of new and better products and varieties to boost their industry and keep wine lovers interested.

An analysis of the economic impact of the northern grape industry uncovers continued growth and opportunities.

Insect pollinators provide essential services to growers of US fruits, vegetables, nuts and seeds and honeybees are their star performer accounting for over two-thirds of the agricultural output attributed to insect pollination. Research projects and extension programs are uncovering new information to help Minnesotans protect this essential insect.

Christopher Philips and his team are working to gather data on the invasive brown marmorated stink bug (BMSB) and how it is affecting Minnesota apple orchards. As there is currently no data available in this area, they are focusing on providing provide knowledge that will aid in optimizing monitoring and control strategies for this invasive pest.
