Pest Management in Minnesota Agriculture

Insect pests have harmed harvests in Minnesota country since European immigrants first arrived in the area. Most local farmers, however, did not actively manage pests. Instead, they planned for the risk of losing some of their crop. It took both huge losses from the late 1800s grasshopper plagues and the industrialization of agriculture for Minnesota’s government to invest in pest management methods.

Weyerhaeuser, Frederick (1834–1914)

Frederick Weyerhaeuser was a prominent, self-made lumber capitalist and millionaire in the Midwest during the Gilded Age. Nicknamed "the Lumber King" and "the Timber King" during a time when lumber ranked alongside iron and the railroads as a source of industry, Weyerhaeuser created a syndicate that controlled millions of acres of timberland. The syndicate also controlled sawmills, paper mills, and processing plants.
