Abstract

An experiment was conducted to control broad-leaved weeds in irrigated wheat fields at Islamabad irrigated Research Station. Treatments were arranged in a randomized complete block design with four replications and 13 treatments. Treatments included application of Bromoxynil + 2,4-D at 420, 560, 700, 840, 980 and 1120 g a.i. ha-1, 2,4-D + MCPA at 1012.5 g a.i. ha-1, Diflufenican + Mesosulfuron methyl + Iodosulfuron methyl sodium + Mefenpyr-diethyl at 1012.5 g a.i. ha-1, Tribenuron-methyl at 15 g a.i. ha-1, Diflufenican + Mesosulfuron methyl + Iodosulfuron methyl sodium + Mefenpyr-diethyl at 132 g a.i. ha-1, Dichlorprop-P + MCPA + Mecoprop-P at 1500 g a.i. ha-1, Bromoxynil + MCPA at 600 g a.i. ha-1, Dicamba + 2,4-D at 371.2 g a.i. ha-1, Triasulfuron + Dicamba at 126 g a.i. ha-1. Weed dry weight reduction were evaluated 30 days after spraying. Grain yield, biological yield and spike per square meter were measured at harvest. Results showed that, Bromoxynil + 2,4-D (Buctril Universal 56 EC) at rate 840 g a.i. ha-1 can control most broad-leaved weeds in wheat fields and increased grain yield and biological yield at 127.65% and 228.2% respectively.
