Mortality in Plantations of Dalbergia sissoo Raised from Seedlings and Clonal Material

The pathological symptoms developing in the trees of Dalbergia sissoo (Shisham) in plantations raised from the seedlings and clonal material in a high mortality area were compared. The seedling plantation raised on an ideal site along river Gaula at Haldwani showed stem cankers , bands and oozing of dark pitch. But there was no yellowing of leaves , wilting and dying of trees. On the other hand , plantation raised from the clonal material showed yellowing of leaves and outright killing of trees up to 32%. But no stem infection of any kind was observed. The area was leased for agroforestry. This practice damaged the stem and ischolar_mains causing infection and subsequent mortality.
