So my Southern Red Oak tested positive for Xf that causes BLS and a strong chance that a Black Oak next to it has it as well. The Black Oak sample:

"The sample repeated again as elevated. Elevated samples are those that test below our positive threshold, but possess an elevated optical density value."

So the chances are high that the Black Oak has BLS. The Black Oak has declined more rapidly then the Southern Red Oak which shows very little decline, so should I assume that the Black is infected as well? Although there is no cure for BLS what are some choices I can do to help the trees live longer? Treat with anti-bacteria, prune limbs affected as well as mulch (although we have had 47" of rain this year and the average amount of yearly rain is 47").
