Fusarium wilt in vandas

[ingse]

Reading some of the other threads on this forum about Fusarium and searching w.w.w. my world just collapsed and i cant stop crying at the moment.
Some of my largest vandas has not been growing like usual and i did think it might be because we have a heatwave here and maybe i did not manage to water them enough in this heat.
Looking closer at the leaves and the roots i just realized that something was very wrong.
I have about 250 large vandas and i think all of them is infected. Some of my smaller sized vandas seem to also be infected so i think this is my last day as a vanda grower.
Here is some pictures of my disaster.
