Soil inoculation relative success

I have been trying to inoculate rhododendron roots with Phytophthora spp for a while and Kim and I have tried several methods that are reported in the literature. I set my latest trial up in the mist chamber to maximise the water availability and finally I seem to have symptoms all be it in only one rep out of three and on only one species out of 7 but never the less I have symptoms yay. See the wilting plant on the right compared with happy plant on the left.
