Abstract
The experiment was conducted under pot conditions during kharif, 2007 in the net house of Assam Agricultural University, Jorhat, Assam, India to manage the disease complex caused by M. incognita and R. solani on okra (Var. Parvani Kranti) using Trichoderma harzianum and Pseudomonas fluorescens. Earthen pots of 3 Kg capacity were used for the experiment. Each pot was inoculated with M. incognita (2J2/g of soil) and R. solani @ 0.2%(w/w). The efficacy of the bio agents were tested both as seed treatment as well as soil application singly and in combinations and compared with a known nematicide (Carbosulfan 25 ST) and a fungicide (Carbendazim 50% WP). Both the bioagents were found to be significantly effective in reducing.the damage and increasing the growth parameters of okra as compared to the treatment inoculated with M. incognita and R. solani. However, seed treatments with either of the bioagents or both were found to be more effective as compared to soil application in reducing the pre and post emergence damping off, galls, egg masses as also nematode population and increasing the growth parameters which was comparable to the treatment with both the chemicals as seed treatment and uninoculated control. This indicate that the effectiveness of the bio agents depend on their proper method of delivery.
