  2. Why should farmers and Ag Applicators/Agronomists know about Invasive Species • Invasive species cause economic, environmental or human harm • Invasive species (IS) are found in rural MN • As advisors to farmers you need to be aware of the IS that may affect farmers income • As an applicator you need to be aware of pesticides that are used to control IS

  3. Invasive Species in MN(Farmers should be aware of Invasive Species) • Buckthorn • Oriental Bittersweet • Emerald Ash Borer • Brown Marmorated Stink Bug

  4. Buckthorn • Native to Europe • Settlers planted Buckthorn in US in 1850’s • Spread by birds eating seeds • Takes over woodlands • Pull or treat with labeled brush herbicides • Plant native or approved shrubs and trees

  5. Buckthorn:(Winter Host of Soybean Aphid) Eggs Soybean Aphids and eggs on bud Rhamnus cathartica, An exotic invasive tree

  6. Oriental Bittersweet • Native Bittersweet: OK (orange berries) • Oriental Bittersweet: Invasive (yellow berries) • Woody vine can grow over 66 feet in length • Reproduces by seed, rhizome, and stolons • Male and female plants (Female plants have seeds) • Takes over sites, kills all plants with canopy • Pull or brush herbicide – repeat treatments

  9. EAB - Watch • MDA is monitoring for EAB • Over 4,500 purple traps • Over 34,000 parasitic wasps released • Plant trees other than Ash • Diversify rural tree plantings • If woodpeckers on live Ash trees or EAB leaf feeding in upper canopy, call MDA

  10. Brown Marmorated Stink Bug • Native to Asia • In Minnesota (Twin cities, Winona) • Not yet found in MN Soybeans • Native stink bugs – OK • Dark antennae with light bands • Light/dark banding on edges of shell • Fall home invader, many host plants Rutgers
