The “Pesticide Chip”: Chemical Legacies and Agrarian Futures in Costa Rica

open access: yesAntipode, Volume 58, Issue 2, March 2026.
Abstract For decades, agro‐industrial capital has adopted cascading chemical and biotechnical interventions, or fixes, to secure accumulation through the cultivation of monocrops. We develop a framework that centres on how monocrop‐induced susceptibility to pests and pathogens—and the patchwork of fixes to address these—produces uneven chemical ...
