Data for: Spillover effects of organic agriculture on pesticide use on nearby fields

AbstractThe environmental impacts of organic agriculture are only partially understood and whether such practices have spillover effects on pests or pest control activity on nearby fields remains unknown. Using roughly 13,000 field observations per year from 2013-2019 in Kern County, CA , we estimate that organic crop producers benefit from surrounding organic fields, decreasing overall pesticide use and pesticides targeting insect pests. Conventional fields, in contrast, tend to increase pesticide use as the area of surrounding organic production increases.
