3E: Trends

A remarkably detailed picture can be painted of trends in corn and soybean herbicide use nationally and in key states by tracking changes over the last several decades in the herbicide use metrics described on the previous pages.

Access below hard copies of a series of trend tables covering corn and soybean herbicide use.

NOTE: Data for all years is not available for all states and thus the timeline available in each table may vary.
