A field experiment was conducted during kharif 2015 at College of Agriculture, University of Agricultural and Horticultural Sciences, Shivamogga to study the influence of herbicide integrity on growth and yield of maize. The treatments include sole application of saflufenacil 70 WG @ 51, 68 and 85 g a.i. ha-1,dimethenamid-P72 EC @ 450, 600 and 750 g a.i. ha-1 and atrazine 50 WP @ 1.25 kg a.i. ha-1 and combined application herbicides saflufenacil + dimethenamid-P (Integrity 66.8 EC) @ 501, 668 and 835 g a.i. ha-1.In addition to package of practices, weed free check and untreated control were also included for comparison. 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 lower weed index (14.0 %) and higher plant height (189 cm),maximum leaf area (7.93 dm2) and total dry matter accumulation (281.70 g plant-1) in maize. yield components viz., cob length (18.33 cm), grain yield per plant (164.45 g plant-1) and higher grain yield per hector (7420 kg ha-1) recorded with same treatment were found high. Thus, from the study, it can be inferred that 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 and effective weed management.
