Abstract The concentration and amounts of three chlorinated insecticides were lower in runoff from a rotation system of potato ( Solanum tuberosum L.), oats ( Avena sativa L.), and sod, than under continuous potato cropping. Runoff samples from natural runoff plots were collected following each storm, and the amounts of DDT, endrin, and endosulfan were analyzed with a gas chromatograph. The amounts of pesticides in runoff were small compared to the amount applied. The concentrations of the insecticides in the runoff (soil‐water suspension) were generally greater than those found in the settled soil (sludge).
