A pot experiment was conducted to test the bioefficacy of nanocomposite based slow release formulation of atrazine herbicide to control Striga asiatica in sugarcane during 2018-2019 in polyhouse, University of Agricultural Sciences, Dharwad. The experiment was laid out in a randomized block design and replicated thrice with seven treatments viz., nanocomposite loaded with atrazine (NCA) @ 1.25 kg a.i./ha applied at 80 DAP, 95 DAP and 110 DAP, atrazine @ 1.25 kg a.i./ha applied at 80 DAP, 95 DAP and 100 DAP and Weedy check. Observations on first days to Striga emergence, Striga density, Striga dry weight, Striga control index and Striga seed capsules per plant were recorded. NCA applied at 95 DAP delayed the emergence by 30 days than weedy check. Moreover at 165 DAP, lower Striga density (2.33 0.2 m-2), Striga dry weight (0.86 g 0.2 m-2), Striga height (1.32 cm), Striga control index (100%) and number of Striga capsules (0 plant-1) recorded with the application of NCA @ 1.25 kg a.i./ha at 95 DAP.
