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 M 3 (0.23, 0.35, 1.61 and 1.78/ plants, respectively) followed by eco-friendly pest management module M 1 (0.23, 0.98, 1.50 and 1.51/ plants, respectively) and botanicals bio-pesticides module M 2 (0.30, 0.99, 1.62 and 1.65/ plants, respectively). As far as yield and economics is concerned, module M 3 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.
during Rabi season of the year 2013-2014. The treatment imidacloprid 0.005 per cent (0.19 aphid index/plant) was found to be most effective followed by thiamethoxam 0.01 per cent (0.33 aphid index/plant). Verticillium lecanii 0.40 per cent (0.58 aphid index/plant), azadirachtin 0.002 per cent (0.62 aphid index/plant) and dimethoate 0.03 per cent (0.77 aphid index/plant) were the next in order. The highest marketable pod yield (30.37 q/ha) and maximum per cent increase in pod yield of cowpea over control (84.28 %) was recorded from the plots treated with thiamethoxam 25 WG @ 0.01 per cent.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
