根部増強処理によるナシ白紋羽病発病樹の樹勢回復

抄録

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.
