Director of Research, Minnesota Soybean Research and Promotion Council
Terrestrial invasive species have impacted, and will continue to impact, soybean yield, quality and profitability. Soybean aphid, a Chinese terrestrial invasive species, is the primary insect impacting soybean yield in Minnesota. It’s primary overwintering host, buckthorn, is also a rather invasive terrestrial tree/shrub species, found in Minnesota woodlots and forests.
Our concerns regarding movement of Palmer amaranth and the Marmorated Stink Bug into Minnesota reflect our potential future involvement in the management of other terrestrial invasive species. As the old saying goes, an ounce of prevention is worth a pound of cure. Preventing these species from establishing populations in Minnesota will be far more successful than developing solutions for them once they arrive.
