Abstract  

A survey carried out in Saptari and Rupandehi districts in April to May 2004 has indicated that sissoo die-back is still prevalent. Dead trees per hectare are found less in community and private plantations in Saptari as compared to the survey results of 2000. In Rupandehi district, the dead trees per hectare in all types of plantations is slightly increased from 44 to 47 whereas dying trees per hectare has considerably decreased from 83 to 34 during 4-year period. The trend is just the opposite in Saptari district where percentage of dead trees is less now but the percentage of dying trees is higher in 2004. The trend of dead trees in private plantation in Rupandehi district is almost the same during 4-year period but there is a slight decrease in percentage of dead trees in community and institutional plantations during that period. 5% and 4.4% trees are dead, while 5.5% and 3.9% are dying in Saptari and Rupandehi districts respectively. In private land, the trees of all age classes (6- 20years) covered in the survey had been affected by the die-back. Death of sissoo trees in private land has led the farmers to select fruit trees as an alternative to sissoo. There is no definite trend in effect of die-back disease based on increasing age of plantation. Around 5% dead and dying trees signify that the level of die-back effect in both the districts is low.
