Abstract


A field study was conducted to investigate the impact of different concentration of Nativo 75 WG (trifloxystrobin 50% + tebuconazole 25%) on physiochemical changes in Bunny hybrid Bt cotton. In the present study, Nativo 75 WG was sprayed twice at different concentration of @ 250, 300, 350 g/ha along with Carbendazim @ 500 g/ha. The samples were collected 40, 60, 80, 120 days after sowing (DAS). While examining one of the physiological parameter i.e. chlorophyll index, Nativo @ 300 g/ha revealed significantly higher value. Similarly in biochemical parameters, such as soluble protein, nitrate reductase activity and accumulation of phenols, Nativo @ 300 g/ha showed positive influence over the stages. The application of fungicide Nativo 75 WG improves the growth of the plant in cotton during flowering and boll formation stage which ultimately resulted in greenness of leaf. Thus, Nativo @ 300 g/ha can be successfully employed as a foliar spray under field conditions to enhance the physiochemical changes in Bunny hybrid Bt cotton.
