A study was conducted to identify and assess the cause of mortality in Blue pine (Pinus wallichiana) forest of Gangotri Range in Uttarkashi Forest Division (Uttarakhand). A phanerogamic parasite; dwarf mistletoe, Arceuthobium minutissiumum was identified as the causal organism of mortality in Blue pine in Pantangana block of Gangotri range. The incidence of parasite was recorded 70.37 per cent with 14.81 per cent mortality of trees.

A new ischolar_main-rot disease of Dalbergia sissoo caused by Amauroderma niger has been studied in detail. The pathogen has been described as a new record for India along with cultural characters. The pathogenicity has been established through artificial inoculation. The disease spreads from tree to tree through ischolar_main contact.- A Report on Mortality of Oak in Dangangaon, Mori Block, Uttarkasid (Uttaranchal)

Three plantation sites with G.48 clone of Populus deltoides exhibited the occurrence of a new stem canker and sapwood stain disease in and around Doon valley. Ceratocystis sp. was identified as causal organism. Excessive water availability at the sites, insect vector and insolation injuries might have served as the infection courts for the disease.- Pestalotiopsis Stem Canker of Jatropha curcas

Kikar (Acacia nilotica) is an important agro-forestry species found in plains of Northern India. From last few decades the decline of the species has been recorded and drying and dying of the trees is still going on. For the purpose of study, Punjab and Haryana, where wood of kikar (Acacia nilotica) is very useful were selected. Apart from the soil factors, average rainfall and global warming, impact of development activities and urbanization, like Road widening, expansion of cable network, blazing, lopping and injuries caused to the trees during operation are found deep major causes. Role of decay and ischolar_main rotting fungi, which harbor the exposed and injured portion of the tree has also been recorded.Keywords

Treatmont of potting mixture with fungicides (ditbane M-45, blue copper, brassicol and captaf) was observed to delay mycorrhizal development in pine seedlings in experiment conducted in a New Forest Nursery though such treatment did not affect the viability of mycorrhizl inoculum. Treatment of polythene soil with fungicides and mycorrhizal inoculation of the same can therefore be done simultaneously for control of damping off fungi as well as development of mycorrhiza in ischolar_mains of pine seedlings Mycorrhizal development was earlier in pine seedlings pricked in April than in those pricked in November-December.- Bark Canker and Die-back of Dalbergia Sissoo in Haryana and Punjab Caused by Lasiodiplodia Theobromae

Lasiodiplodia theobromae, a fungal pathogen causing stem cankers on Dalbergia sissoo is reported in Haryana and Punjab for the first time. It might have reached to D. sissoo from fruit trees like pear and peaches grown in the area where this fungus was reported earlier. The disease exhibited symptoms like dark spots on the bark with splitting, cankers and oozing of sap. The affected trees showed die back to varying degree. Bavistin was found as the most effective fungicide inhibiting complete growth of the fungus at 100 ppm among other fungicides. Among biological control agents Trichoderma harzianum exhibited distinct antagonism, T. koningii exhibited mycoparasitism, T. viride showed inhibition at the line of contact whereas Aspergillus niger showed overlapping. Spraying with Bavistin or Trucop on stem, branches and twigs of affected trees is recommended for checking the further spread of the disease. Chaubatia paste can also be applied while pruning the trees to check entry of the pathogen.Keywords
