Abstract
Bacterial isolates of Agrobacterium radiobacter inhibit the growth of phytotoxic micromycetes in vitro and also in vivo. The inoculation of roots with A. radiobacter can eliminate the apple replant disease (ARD) as shown in both glasshouse pot experiments with apple seedlings and nurseries with apple rootstocks.
The dying-off of plants was significantly lower in treated plants than in control.
The inoculated apple seedlings and/or rootstocks grew better in the soil with ARD as compared to water-treated control. A. radiobacter used for the inoculation may affect the plants by changing the composition of rhizosphere microflora and by reducing the number of colony forming units (CFU) of phytotoxic micromycetes, which might contribute to the ARD.
