Horseradish country

Madison, St. Clair and Monroe counties grow a large share of the nation's horseradish on the light, sandy, potash-rich soils of the American Bottom, and Collinsville hosts the International Horseradish Festival every June. About a dozen grower families farm from 5 to 500 acres, harvesting from September to April; one Edwardsville grower farms 200 acres at about 7,000 pounds an acre, and the country's largest horseradish distributor, based in Collinsville, markets 10–12 million pounds of roots a year.

Why horseradish changes the spray plan

SIU research in 2019 found that 2,4-D drift at rates as low as 1/1,000 of a field rate cut horseradish yield 41–100%, and at half a field rate the loss was total, while dicamba caused little injury at drift rates. The paper called the area east of St. Louis the most concentrated horseradish production in the country. Operators map every horseradish field nearby, choose products and droplets with them in mind and fly only with wind blowing away from them.

Metro East levees

The Metro East levee system runs 65 miles from Alton to Columbia and protects about 156,000 residents and 4,000 businesses; FEMA recertified it for a 100-year flood in 2022, and 2019 brought the region's second-highest flood after the record 1993 stages that broke levees across the Mississippi valley. Bottom fields behind the levees stay soft after high water, and a drone treats them without ruts. Levee slopes and ditches are mapped as no-spray zones.

Airspace near St. Louis

St. Louis Regional Airport at Bethalto has Class D airspace within 4.4 miles from the surface to 3,000 feet, carved out of the St. Louis Class B area that reaches into the western county. Fields in controlled airspace need FAA authorization before every flight, and crews plan those jobs ahead. The Bethalto tower runs from 7 a.m. to 10 p.m., and a replacement tower was approved in 2025.

Horseshoe Lake and Highland's dairy roots

Horseshoe Lake State Park in Granite City covers about 2,960 acres around Illinois's second-largest natural lake. In Highland, Swiss merchants founded the Helvetia Milk Condensing Company in 1885, the start of Pet Milk and the first shelf-stable evaporated milk. Its headquarters moved to St. Louis in 1921. Just south in St. Clair County, near Collinsville, the Cahokia Mounds UNESCO World Heritage Site covers about 2,200 acres. Lakes, parks, historic sites and town edges are mapped as no-spray zones.
