Use of Wetting Agent (Surfactant) to Enhance the Phytotoxicity of 2, 4-D for Control of Broad Leaf Weeds in Wheat

A. Tanveer, M. Ayub, R. Ahmad and A. Ali


A field study was conducted to evaluate the effect of adding a wetting agent to 2, 4-D on weed control in wheat. Triton @ 200 and 250 was used as wetting agent with recommended (1.3 kg ha-1) and reduced rate (1.00 kg ha-1) of 2, 4-D . Weedy check and sole application of 2, 4-D was also included for comparision. Different weed control treatments significantly reduced the weed population compared to weedy check. Appliction of 2, 4-D @ 1.3 kg ha-1 added with wetting agent @ 200 ml kg-1 of 2, 4-D gave 39 per cent more grain yield than weedy check.
