Ray I think this question is for you..

I was looking at rotating some different fungicides bec i don't want to make any resistant strains..hmmmm
SubdueMaxx looks like good stuff at about 1000 bucks a gallon.
They always seem to leave out orchids. They list everything else under the flipping sun but orchids..Orchids are the rodney dangerfields of the plant world.
