Summary of the book-Health of shisham in North Eastern UP,INDIA Sissoo(Dalbergia sissoo Roxb.) is a medium to large-sized deciduous tree suffering from wilting .A large number of synthetic fungicides are used to control fungal growth but they are pollutive in nature.In nature plants are available which have volatile activity that can destroy fungal pathogens.So far essential oils were extracted from higher plants and tested against Fusarium solani and Fusarium oxysporum.The oil of Putranjiva roxburghii showed complete inhibition of mycelia growth of both test fungi at 500ppm.The oil was thermostable at its minimum inhibitory concentraion of 500ppm and exhibited wide range of activity at 1000ppm.Moreover,the fungitoxicity was not destroyed by autoclaving and storage upto 120 days.The root and bark extract of Putranjiva was also found to be effective against both species of Fusarium.In this way this plant have overall anti action against Fusarium.So a little mixed field trial at nursery bed level was conducted with Putranjiva which showed no wilting symptoms compared with separately grown control sets of sissoo.So Putranjiva may be used against Fusarium to protect sissoo.
