ABSTRACT
A field experiment was conducted during kharif 2015 at College of Agriculture, University of Agricultural and Horticultural Sciences, Shivamogga. The treatments consist of herbicide saflufenacil + dimethenamid-P (Integrity 66.8 EC) @ 501, 668 and 835 g a.i. ha-1, sole application of saflufenacil 70 WG @ 51, 68 and 85 g a.i. ha-1 , sole application of dimethenamid-P 72 EC @ 450, 600 and 750 g a.i. ha-1 and Atrazine 50 WP @ 1.25 kg a.i. ha-1. In addition package of practices, weed free check and untreated control were also included for comparison. Pre - emergence application of saflufenacil was found more effective against broad leaved weeds while, dimethenamid-P against the grass and sedges. The combi- product of saflufenacil 68 g l-1 + dimethenamid-P 600 g l-1 EC (Integrity 66.8 EC) @ 668 g a. i. ha-1 acting as broad spectrum herbicide was found more efficient in controlling all types of weeds by recording highest weed control efficiency (72.63%). From the results, pre tank mixture of saflufenacil 68 g l-1 + dimethenamid-P 600 g l-1 EC (Integrity 66.8 EC) @ 668 g a. i. ha-1 can be used as pre - emergence safely in maize for better productivity (7420 kg ha-1)and effective weed management.
