I have tested for virus. Probably will again in the future. But, the results have to be viewed with caution.
I have one Cattleya that tested negative with the agdia strips. It grows on ok but not great and has been consistently blooming with some amount of color break every time. I am convinced it has a virus just, not one the agdia strips test for.
On the other hand, one of my dendrobiums tested positive for CMV. It grows very slowly but blooms reliably and without color break every year.
The reason I would go ahead and test is, to see if a plant that is not doing well is worth fighting for. The two plants above are growing along without any extra fuss. It would be good to know if a plant I keep treating for apparent pest or disease really just has, an untreatable, virus. No point in continuing that battle.
Just my two cents.
