Recovery of the Japanese pear trees with decline from white root rot (Rosellinia necatrix) after root reinforcement treatment.

Abstract

Recovery of Japanese pear trees from a decline associated with white root rot caused by Rosellinia necatrix was examined after root reinforcement treatment with healthy stocks. Fluazinam alone, which is highly effective against white root rot, could not reverse the decline. However, the declined trees were recovered successfully from the syndrome after application of Fluazinam in combination with the root reinforcement treatment with some healthy stocks.
