Insect pests problems of Acacia nilotica ssp. indica, Albizia lebbeck, Casuarina, Teak, Tamarind, Neem, Phylanthus emblica, Pongamia pinnata, Sizigium cumini Ailanthus excelsa, Aegle marmalose were studied and Integrated methods of management of the key pests worked out. A Pest Calendar reflecting the period and level of occurrence of the key pests of the said tree species has been developed.
Nursery and Plantation Insect pests of fast growing native tree species such as Ailanthus excelsa, Melia dubia, Gmelina arborea, Dalbergia sissoo, Thespesia populnea and Bombax spp. were studied and key pests identified.
New invasive gall insect pest, Leptocybe invasa Fisher & La Salle on eucalyptus was reported
Management of Cauarina and Teak live wood stem borers through biological control using entomopathogenic fungi developed.
Seed pest problems of A. nilotica, A. lebbeck, Casuarina, and Tamarind were studied and sound seed storage practices against the major insect pests developed.
Important disease problems confronted nurseries and plantations of Eucalyptus, Casuarina, Tamarindus, Artocarpus, Terminalia, Acacia, Bamboos and Teak were investigated and suitable management strategies worked out.
Species diversity of Ecto and Endo mycorrhizae fungi in Nilgri Biosphere was studied and reported about 20 different ecto-mycorrhizae fungi associated with different tree species viz., Acacia mearnsii, A. melanoxylon, Eucalyptus globulus, E. grandis, Cupressus macrocarpum, Pinus patula., Tectona grandis, Shorea robusta and Bamboos.
Effect of ecto-mycorrhizae fungus for quality seedling production of Eucalyptus, Casuarina and Acacias were tested and effective dosage and methods of application developed.
Technology for reclamation of Bauxite minespoils using beneficial microbes and suitable tree species was worked out and standardized.
