Figure showing herbicide use intensity from 1990 through 2023. Blue lines show the trend in herbicide use from 1990 thorugh 2015, when a previous analysis was published. The blue lines show a steady increase in all crops (maize, soybean, coton, rice, spring wheat, and winter wheat. Red lines show the average trend for a more recent time period, from 2006 through 2023; for maize and soybean, the herbicide use intensity increased much more rapidly over the last 20 years compared to earlier periods. For cotton and winter wheat, the trend was abou the same. For rice and spring wheat, the increase has slowed.
