Abstract


Investigation on development of suitable integrated pest management module for major insect pest of cabbage (Brassicae oleracea var. capitata) was carried out in experimental field of Navsari Agricultural University, Navsari, Gujarat. In case of larval population of C. binotalis, S. litura, P. xylostella and H. armigera was found in sole synthetic insecticide module M3 (0.23, 0.35, 1.61 and 1.78/ plants, respectively) followed by eco-friendly pest management module M1 (0.23, 0.98, 1.50 and 1.51/ plants, respectively) and botanicals bio-pesticides module M2 (0.30, 0.99, 1.62 and 1.65/ plants, respectively). As far as yield and economics is concerned, module M3 recorded highest yield of cabbage heads (28322.0 kg/ha) and consequently higher net gain over control (122050 Rs./ha) and higher net BCR (1:41.01). However, its effect in destructing natural fauna, polluting environment and causing residual problem should not be overlooked. Eco-friendly pest management module and botanicals and bio-pesticides module was next effective module in recording yield and net profit besides any adverse effect on natural fauna and did not leave any toxic residue.
