Abstract

Weed management in non-cropped areas with pre-mix of indaziflam and glyphosate in Punjab.

Abstract

Non-cropped areas are infested with diverse weed flora including annual and perennial grasses, sedges and broad-leaf weeds. The field efficacy of pre-mix of indaziflam plus glyphosate was evaluated for effective weed management in these areas. The field experiment was conducted over two years in Ludhiana (India). Seven treatments including pre-mix formulation of indaziflam-20 + glyphosate 400-420 SC (60 + 1200, 70 + 1400 and 80 + 1600 g/ha), glyphosate (1230 and 1600 g/ha) and indaziflam (80 g/ha) along with untreated control were evaluated. Major weed species at the experimental site were Cannabis sativa, Parthenium hysterophorus, Verbesina encelioides and Xanthium strumarium. All herbicidal treatments recorded complete mortality of C. sativa and P. hysterophorus till 30 days after application (DAA) while in case of V. encelioides and X. strumarium, complete mortality was recorded till 120 DAA. Pre-mix of indaziflam plus glyphosate at 80 + 1600 g/ha had >80% control of all weed species during both years till 60 DAA, and it was at par to its lower dose of 70 + 1400 g/ha; results with sole application of indaziflam and glyphosate were inconsistent.
