Landscape drivers of insecticide use

Based on more than 100,000 field-level observations in Kern County, California, a study evaluating the effect of agricultural intensification on insecticide use finds that insecticide use decreased with increases in crop diversity but increased with field size, while the relationship between insecticide use and the proportion of the surrounding region in cropland depended on spatial scale, suggesting differences in insecticide inputs between homogenized, low-diversity farmland and complex, species-rich farmland. - Read at PNAS
