Abstract


A field experiment was conducted to determine the effects of post-emergence herbicides applied at the recommended and reduced doses on weeds in durum wheat. A randomized complete block design was employed with 4 replications per treatment. Weed density differed significantly among the herbicide treatments. Our results show that the herbicides could effectively control A. sterilis, A. myosuroides and G. aparine when their doses were reduced by 15%. The herbicides pyroxsulam and mesosulfuron-methyl+iodosulfuron-methyl-sodium showed some difficulties in controlling S. arvensis even at the labeled recommended dose.
