A 10-fold-diluted suspension of a fertilizer paste (product name: TP, Taki Chemical, Hyogo) was tested for suppression of violet root rot of apple caused by Helicobasidium mompa in infested kuroboku soil (soil texture: L), gray lowland soil (SL, LiC) and brown forest soil (HC, SL). In pot experiments with infested soils, disease severity on apple rootstocks (Malus prunifolia var. ringo) in all soils treated with TP was lower than on those treated with tap water. These results suggested that a fertilizer paste applied to the soil surface around the trunk bases of apple trees will suppress disease in most apple orchards.
