Most common on elm, maple, birch, oak, poplar, sycamore, and willow.
Sap seeps out of the infected area and flows down the trunk. This foul smelling substance often discolors or kills the bark. Insects may
be attracted by the odor. Wounds provide entry for the fermenting organisms.
There is no cure or prevention for this condition. Water infected trees deeply once
a week during dry spells. Drilling holes eight to 12 inches below the fluxing area
relieves sap pressure but this is not a recommended treatment. Please contact your
local county extension office for current information.
