Abstract: Experiments were conducted to produce bio-agent colonized seedlings using effective formulations of bio-agents viz., Trichoderma viride Pers., 1794 (CFU 2x106 /g), Pseudomonas fluorescence Migula., 1895 (CFU 2 x 108/g) and Purpureocillium lilacinum Luangsa., 2011 (Paecilomycis lilacinus) (CFU 2 x 106/g). Observations were made on evaluation of the compatibility of these bio-agents and their bio-efficacy against root-knot nematode (Meloidogyne incognita Chitw.) and Fusarium wilt (Fusarium oxysporum f. sp. conglutinans) on seedlings of cauliflower (Brsassica oleraceae var. botrytis). Significant increase in plant growth and reduction in disease incidence (Fusarium wilt) were observed. Formulations of bio-pesticides were used in combinations for production of organic seedlings of cauliflower. Treatments with combination of formulation of 3 bio-pesticides proved to be effective promoting plant growth with reduction in disease incidence of Fusarium wilt in seedlings satge. Seedlings were transplanted to pots under controlled conditions showed vigorous growth and were able to manage the disease complex caused by Meloidogyne incognita and Fusarium oxysporum. Results proved that these bio-agents were effective in sustainable management of disease complex in cauliflower.
