You’ve probably heard about them — the ubiquitous insecticide that lurks within the plant and isn’t sprayed on like traditional pesticides. Neonicotinoids, as the name suggests, are similar in composition to nicotine and cause certain neurological receptors to be over-stimulated in insects. As a result, bugs that feast on plant tissue that has absorbed the chemical soon incur neurological damage, which can cause paralysis and death. This systemic type of pesticide, which includes imidacloprid, thiamethoxam, and clothianidin, is applied to seeds and absorbed into the plant as it grows, creating an life-long resistance to mostly corn- and soybean-hungry insects. Throughout the European Union, they’re also applied to sunflowers, oil seed rape (canola) and sugar beets.
