Abstract

 Present investigation carried out to study different weed control methods in spring SAFFLOWER (Carthamus tinctorius) under rain fed condition. The experiment was conducted in Sararood Research Station located in west of Iran in 2006. The experimental design was a factorial based on RCBD with four replications. Factor A was included 4 different herbicides Trifluralin at 960 gr a.i./ha, Pendimethalin at 660 gr a.i./ha, Ethalfluralin at 1172.5 gr a.i./ha, Imazametabenz at 625 gr a.i./ha. and Factor B was 4 different method including without MECHANICAL CONTROL, hand weeding at the 6 leaves stage, cultivator at 6 leaves stage, hand weeding at the 12 leaves stage + cultivator at 6 leaves stage along with two checks namely without weed, and without any weed control. The result showed that MECHANICAL CONTROL after the herbicides application increased weed control compared with the herbicides applied alone. A cultivator at 6 leaves stage with a hand weeding at 12 leaves stage with Imazamethabenz herbicide application increased weed control compared with all other stage. Decreasing of weed dry weight was observed in integrated treatments and sole herbicides treatment had less effect on reducing of weight dry weed.
