[OGD] Fusarium in Vandas

I have had a severe fusarium problem for some time, which got its initial start 
from the use of damaged neem oil.  I have rescued many, many plants with 
thiophanate methyl (Cleary 3336, OHP 6672, Bonomyl(sp?), Fertilome Halt, etc.). 
 I spray daily for a while, then every few days for a while, then occasionally. 
 This worked well on most orchids, with the new growth coming in normal as the 
gold standard of cure.  However, this is a less than adequate treatment for 
Vandas, as it is hard to get the chemical into the area around the new leaves 
emerging, and I lost most, but not all of my infected Vandas, and Vandas seem 
to be particularly susceptible to the Fusarium.  I even lost the first 
replacement seedling for one clone after I knew to spray all the Vandas for 
protection, so being particularly careful to spray regularly all your Vandas is 
a good idea.
