Optimizing herbicide use in wheat (Triticum aestivum) under rain-fed conditions

Widespread prevalence of weeds poses a severe threat to rain-fed wheat production in Pakistan and other places. Weed control efficacy of different herbicides and their dose rates in wheat crop was investigated under rain-fed conditions during the period of 2005 to 2006 and 2006 to 2007.
