Is Fung-onil recommended for treatment of black knot on cherry trees?


Fung-onil Multi Purpose Fungicide Concentrate is not labeled for black knot.  Junction is the only fungicide we carry that is.  It appears that this disease is best controlled by mechanical methods though.  There is a great article by the University of Maine here.
