Canola fields were infested with the broomrape in Iran. The possibility of broomrape chemical control was investigated in the greenhouse of Iranian research institute of plant protection and infested fields of Golestan, Ilam, Kermanshah, Fars, Chaharmahal and Bakhtiari provinces during 2018-2020. A greenhouse experiment was conducted as a factorial arrangement with a completely randomized design and 4 replications. First level was broomrape species (Phelipanche aegyptiaca Pers. and P. mutelii F.W. Schultz) and second level was herbicides application included: 1&2-Metazachlor+Quinmerac (Butisan star, SC41.6% and Butisan top, SC50%) 2.5 L. ha-1 (pre emergence) 3-Trifloralin (Treflan, EC48%) 2 L. ha-1(pre planting), 4-Glyphosate (Roundup, SL41%) 40 mL. ha-1, 5-Twice application of Roundup 40 mL. ha-1, 6- Roundup 80 mL. ha-1,7-Twice application of Roundup 80 mL. ha-1, 8-Clopyralid (Lontrel, SL30%) 600 mL. ha-1, 9- Twice application of Lontrel 600 mL. ha-1,10- Untreated Control with broomrape 11-Control without broomrape. Field treatments were similar to greenhouse herbicide treatments 5, 9, and 10. The stem number and dry weight of broomrape and yield of canola were measured. The results showed that the most effective treatment was the twice application of roundup 40 ml. ha-1 +AMS in all locations except Ilam and fars provinces. Egyptian broomrape controlled 91, 95 and 74% in greenhouse, Chaharmahal and Kermanshah. P. mutelii controlled 91 and 80% in greenhouse and Golestan. Rapeseed yield increased by 34 and 65% compared to the control in Chaharmahal and Golestan.
