Weed control efficacy and short term weed dynamic impact of three non-selective herbicides in immature oil palm plantation
Efficacy of three herbicides (paraquat, glufosinate ammonium & glyphosate) in immature oil palm plantation was evaluated. The experiment was quadruplicated in randomized complete block design with 13 treatments viz. paraquat at 200, 400, 600, 800 g a.i. per ha, glufosinate ammonium at 200, 400,...

Summary: | Efficacy of three herbicides (paraquat, glufosinate ammonium & glyphosate) in immature oil palm plantation was evaluated. The experiment was quadruplicated in randomized complete block design with 13 treatments viz. paraquat at 200, 400, 600, 800 g a.i. per ha, glufosinate ammonium at 200, 400, 600, 800 g a.i. per ha and glyphosate at 400, 800, 1200, 1600 g a.i. per ha and an untreated check as control. Glufosinate ammonium and glyphosate were much better than paraquat as supported by data on weed mortality, weed dry weight, weed density and sum dominance ratio (SDR). Glufosinate ammonium and glyphosate also affected short-term weed dynamic and were found to be more suitable to control mixed weed in immature oil palm plantation. |
