Compatibility of Trichoderma viride for Selected Fungicides and Botanicals

Ashwani Tapwal, Rajesh Kumar, Nandini Gautam and Shailesh Pandey

Abstract

Trichoderma viride can thrive in diverse environmental conditions as aggressive colonizers of soil and the roots of plants and act as natural bioagent to protect plants from infection by soil-borne fungal pathogens. Laboratory experiments were conducted to test the possibility of combining fungicides and botanicals with Trichoderma viride to work out their compatibility to devise a suitable integrated management of soil borne plant diseases. Five fungicides viz., dithane M-45, ridomil, captaf, blue copper, bavistin and five botanicals viz., Parthenium hysterophorus, Urtica dioeca, Cannabis sativa, Polystichum squarrosum and Adiantum venustum were evaluated at different concentration. Among fungicides only captaf and blue copper had recorded compatiblility to some extent with T. viride. While the water extracts of the tested botanicals were quite compatible with Trichoderma except for C. sativa, which have some inhibitory effect on the growth of pathogens. Present investigation suggests that compatible fungicides and botanicals can be used with Trichoderma in an IDM package to control soil borne plant pathogens.
