| Popis: | Abstract In order to study chemical control of purple nutsedge in potato, a field experiment was conducted in 2007 at the Research Field of Ferdowsi University of Mashhad. Experimental design was randomized complete block with 7 treatments and 3 replications. Treatment included Glyphosate (pre plant ‘PP’ at 1.5 L ai ha-1), Glyphosate (PP at 1 ai ha-1), Glyphosate (post emergence ‘POST’ reduced at 100 ml ai ha-1), Sencore (pre emergence ‘PRE’ at 1.3 kg ai ha-1), hand weeding (two times) weed free and weed infested check. Results showed that effect of different treatments on potato yield was significant. The highest yield was obtained in Sencore (32.31 t ha-1) which had no significant difference with weed free check. The lowest yield (6.27 t ha-1) was obtained when Glyphosate was applied on potato at reduced rate. Sencore controlled purple nutsedge effectively at recommended dose, but applying glyphosate PP and POST was not effective for purple nutsedge control in potato.
