ENVIRONMENTAL SCIENCES, SUSTAINABILITY SCIENCE Correction for “Identifying the landscape drivers of agricultural insecticide use leveraging evidence from 100,000 fields,” by Ashley E. Larsen and Frederik Noack, which was first published May 8, 2017; 10.1073/pnas.1620674114 (Proc Natl Acad Sci USA 114:5473–5478).
The authors note that on page 5477, right column, second full paragraph, lines 6–7, “Our outcome variable was kilograms of insecticide used per cropland hectare” should instead appear as “Our outcome variable was kilograms of insecticide product (active ingredients + adjuvants) used per cropland hectare.”
