Evaluation of biology aspects and chemical management of Triticum boeticum Boiss. in wheat fields

In order to recognized and evaluated of biological properties and possibility control ofwild einkorn (Triticum boeticum Boiss.) growing weed in wheat fields of the West, and was carried out with laboratory, greenhouse and field in Agronomy Faculty, University of Tehran, Karaj, during 2010. Experimental treatments included, temperatures 5, 10, 15, 20, 25 and 30, potential 0, -4, -8, -12 bar that was a randomized complete block design with four replications. Greenhouse and field treatments herbicides were included: diclofop methyl, fenoxaprop-p-ethyl, clodinafop-propargyl, sulfosulfuron, mezosulfuron + iodosulfuron and pinoxaden. Recommended dosage of herbicides was used in 3-5 leaves and middle tillering growth stages of wheat and wild einkorn. Greenhouse and field treatments included were factorial experiment in randomized complete block design with four and three replication, respectively. According to the results observed with increasing osmotic potential significant decrease components germination at different temperatures. In between treatments, causing the loss of seeds and prevent germination of T. boeticum was 35 c°. Greenhouse study showed that weed biomass was affected by herbicide treatment in both stages. Among the herbicide treatments, mezosulfuron + iodosulfuron and diclofop methyl the highest increased weed biomass 37. 3 and 44. 8درصد, respectively, While the sulfosulfuron and clodinafop-propargyl the lowest decreased its 75. 4 and 77. 5درصد to the control. Based on field results and the presence of weeds in fields planted with T. boeticum Shiraz varieties, use of herbicides pinoxaden and sulfosulfuron, according to the appropriate control T. boeticum and less damage to the crop is recommended.
