Abstract

In order to investigate weed control in sesame farms, a two-year experiment with Randomized Complete Blocks Design, 10 treatments and 3 replications was carried out in Jiroft and Kahnuj during 2006-2008. Treatments included trifluralin 48% EC at 2.5 L/ha (pre plant incorporated) + haloxyfop ethoxy ethyl 12.5% EC at 2 L/ha. post emergence of grassy weeds, alachlor 48% EC at 5 lit/ha pre-emergence, oxyfluorfen 24% EC at 2 lit/ha post-emergence, pendimethalin 33% EC at 4 lit/ha pre-emergence, above treatments + one hand weeding, two hand weedings and weed free check. Results indicated that all treatments reduced weed density and dry weight. Trifluralin and alachlor reduced Dactyloctenium aegyptica dry weight by 63 and 56% respectively. Alachlor and pendimethalin reduced Digera muricata dry weight by 94 and 91% respectively. The latter treatments also increased sesame yield by 75 and 65% respectively.
