The homeowner program https://ncipmhort.cfans.umn.edu/consumer-lawns-infested-grubs

Outreach programs were designed to educate professionals, consumers, and park visitors on ways to reduce pesticide use. Our outreach programs included a table at the Monarch Festival for 2 years, an online educational program with site visits, and an online Advisory Committee meeting for stakeholders, state agencies, Master Gardeners, Golf Courses and Nursery Industry that met 3 times. Outreach included websites, 36 talks, 3 peer-reviewed papers, 8 articles for the nursery, golf course, and Master Gardener newsletters. Research supported 3 UMN UROP fellowships and a Post Doc that received a UAlabama professorship

 

An online educational site on pollinator conservation and Japanese beetle management was created at https://ncipmhort.cfans.umn.edu/ipm-case-studies/ipm-case-study-japanese-beetle

 

An article was published in the MN Golf Course Superintendents magazine. JB MN Golf Corse Superintendent's Hole Notes 57(5) June 2022

 

A poster on the research was presented at the UMN Research Symposium on March 14 2024
