A sheet material (2) is disclosed which can be buried in the soil to prevent the entry of roots into unwanted regions. The sheet is a water-permeable material which holds a plurality of polymer bodies (4) containing an effective ingredient of 2,6-dinitroaniline. The effective ingredient slowly diffuses from the polymer into the soil adjacent the sheet material to prevent the root growth over time.
