Copper naphthenate, or copper sulfate, in a suitable carrier appears useful to eliminate growth of roots on the surface of the root ball of nursery plants in containers. Neither chemical presented a problem with soil ball integrity when transplanting, nor did they inhibit root growth following transplanting. While uptake was not determined, phytotoxicity due to excess copper uptake was not observed.
