Leafy Spurge <br />Pag <br />organic matter. A. cyparissiae prefers soils higher in moisture than A. nigrisc~riis, but still <br />prefers moderately coarse-textured soils such as sandy loams and open sites. A. flava <br />does well in coarse soils with high water tables in open and shaded conditions. A. <br />crlva/inae prefers moist, clay soils. <br />Regardless of the management system used, a combination of methods is essential to <br />return leafy spurge-infested ground to a productive state. The key to control leafy spurge <br />or any creeping perennial is to exhaust the root nutrient stores, causing it to collapse. <br />Persistence is imperative to gain control. <br />1CObrado State University Cooperative Extension weed science specialist and professor, bioagricukural sciences <br />and pest management. 2/00.
