Influence of Biocontrol Agents, Plant Products, AM Fungi and Rhizobium on Suppression of Fusarium Wilt and Growth of D. sissoo Seedlings

A field experiment carried out to investigate the effect of biocontrol agents, plant products and biofertilizers including Trichoderma pseudokoningii, T. polysporum, Aspergillus flavus, Vitex negundo extract, Jatropha cake, Arbuscular mycorrhizal fungi and Rhizobium showed a significant increase in germination, height and collar diameter and reduction in mortality of D. sissoo seedlings due to Fusarium wilt in a number of treatment combinations. The results indicated that applications of T. pseudokoningii, AM fungi, Rhizobium and Jatropha cake in combination may be recommended for management of vascular wilt disease and production of quality seedlings of D. sissoo.
