First visible sign may be arrested growth, and foliage of a fading green or slight yellowing colour; foliage of infected trees turns reddish brown; trees can die so quickly that brown needles cling to twigs. Yellowing or wilting and browning begin soon after colour begins to fade. Resin production falls; branch cut from diseased tree may not produce any resin; branch twigs become brittle and dry and break easily. Various wood-inhabiting beetles can vector the nematode.
