STUDIES ON TRICHODERMA VIRIDE FORMULATIONS FOR ENHANCING ITS STORABILITY

Abstract

The present investigation was carried out to evaluate the viability in different formulations of T. viride and also assessment of moisture content present in using formulations of T. viride.Seven different carrier base formulations such as chalk powder, talc powder, charcoal powder, chalk tablet, talc tablet and charcoal tablet with three concentrations 5%, 10%, 15%, one capsule formulationT.viride and culture of T. viride (ISO-1) were evaluated on different period to observe their viability. Different formulations of T. viride maximum (80 × 10 7 cfu/g) was recorded in 15% charcoal powder followed by capsules (78.67 × 107cfu/g),upto 260 days storage. However, least recorded in 5% T. viride(1 × 107cfu/g ) in talc powder. Viability were absent in chalk powder and tablets at different concentration observed till 100 DAI but decline to zero viability. In moisture content, Maximum (34.7%) moisture content was retained up to 260 days of storage in 15% charcoal powder followed by 10% T. viride charcoal powder (30.28%) while it was least recorded in 5% talc powder(2.2%).It was found that the storability maximum in T. viride 15% in charcoal powder with high moisture.
