An investigation entitled “Evaluation of different oils on shelf life study of Trichoderma viride” was carried out during 2017-2018 in the department of Plant Pathology, College of Agriculture, Nagpur. Different oils viz., Paraffin oil, soybean oil, mineral oil, Potato Dextrose broth and talc was extensively used as carrier for Trichoderma viride. As compared to solid based carrier material the survival of Trichoderma viride in liquid based formulations is quite high and has the ability to limit the heat transfer high water holding capacity and maintain water around the cells for their metabolism. Shelf life studies clearly indicated significant differences at all the intervals. Population density of Trichoderma viride in the paraffin oil was 28.06 x 108 CFU/ml in the 1st month whereas the population density of Trichoderma viride in the 6th month was 18.33 x 108 CFU/ml. It was found significantly superior over all other treatment. The effect on percent growth inhibition on Fusarium oxysporum f. sp. ciceri is 79.30 per cent on Rhizoctonia bataticola is 84.85 per cent and Sclerotium rolfsii is 79.14 per cent. It was recorded maximum in formulation containing paraffin oil it was found significantly superior over all the treatments. The effect of liquid formulations on spore germination of Trichoderma viride was also recorded the maximum spore germination are found in formulation containing paraffin oil after six months of storage.
