Abstract

Blue pine (Pinus wallichiana A.B. Jackson) which occurs naturally in the temperate zone of Central and Western Himalayas, is attacked by dwarf mistletoe. It is a disease of low rainfall area and known only from Western Himalayas in Pakistan, Jammu & Kashmir in India and Nepal. A survey was conducted in 2005-2006 in different forest divisions of Kashmir Valley and Jammu. Symptoms and disease intensity were recorded in different girth classes of Blue pine. In young plants, spindle shaped swellings in the infected branches was the most prominent symptom. Mature tree showed deformity of branches and poor crown. There was a linear relationship between increasing girth and disease intensity, for example, only 48 per cent infection was recorded in < 30 cm girth class, while 100 per cent trees were infected in 111-200 cm girth class and above.

Abstract

Studies were carried out om fungal infestation and mycotoxin contamination in fresh and stored seed samples of Shorea robusta. In fresh samples 5 fungi namely Aspergillus flavus, Alternaria alternata, Cladosporium cladosporioides, Fusarium sp. and Rhizopus sp. Were recorded, whereas in stored samples 9 fungi namely A. flavus, A. alternata, A. niger, C. cladosporioides, Cylindrocladium sp. Phoma sp., Fusarium sp., Penicillium citrinum. and Rhizopus sp. were found associated. The pattern of mycoflora incidence was significantly different in samples from all three sources. Interaction of source and season was significant for all fungi observed in S. robusta. The mycotoxin producing fungi were screened for their toxin producing abilities. The amount of aflatoxin produced by toxigenic isolates was quite high. Aflatoxins were detected in almost all samples analysed for mycotoxin contamination.

Abstract

Seed samples from different sources of Pinus wallichiana from Himachal Pradesh and Uttaranchal were evaluated for the occurrence of seed mycoflora. A total of 13 fungi with 22 fungal species were isolated of which species of Aspergillus and Penicillium were dominant. Seed source Kufri (H.P.) reported maximum number of mycoflora i.e. 9 fungi, while in Sawat and Kharapathar (H.P.) only one fungus was recorded namely Aspergillus niger.

Abstract

A new set rot disease of ischolar_mained cuttings of Dalbergia sissoo caused by Fusarium equiset has been described. The disease was found to be encouraged by excessive soil moisture as provided through channels around the raised beds. Soil drenching with 0.05% bavistin or benlate can control the disease when it is observed in beds. A preventive approach can be treating the ischolar_main suckers for about 10 minutes in 0.1% solution of bavistin or benlate before putting them in ischolar_maining medium.

Abstract

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.

Abstract

The reports of surveys conducted to assess the mortality of Dalbergia sissoo Roxb. in India are outlined. The possible reasons are discussed with particular reference to Fusarium solani (Mart.) Appel.& Wr. which is a secondary parasite on the dead ischolar_mains and collaborative organism for the wilting of trees.

Abstract

Effect of systemic fungicides1ike Bavistin, Bayleton and Topsin-M and Baycorwas studied on the development of stem blisters caused by Cronartium himalayense Bagchee on Pinus roxburghii Sargent for two successive years.

Abstract

The paper deals with the current status of stem rust of chir caused by Cronartium himalayense. On the basis of recent surveys conducted in the afforested sites in Tehri and Pauri Garhwal districts, it is concluded that the rust is again gaining epidemic proportions. Strategies to control the rust have been discussed with particular reference to a Cladosporium sp. hyperparasitic on telial columns of C. himalayense formed on its primary host Swertia spp.
