Abstract
Disclosed is a method for controlling and preventing the growth of plant roots using a water-permeable, non-woven fabric made of synthetic fibers coated or otherwise impregnated with a water-insoluble polymeric binder in which is dispersed a water-insoluble inorganic copper compound in an amount effective to stop root growth. The polymeric binder is bound to the fabric and retains and confines the copper compound to the fabric. The coated fabric is used to stop or prevent the growth of undesirable rootlets or radicles which come in contact thereto.
