| Abstract | ||
| Knowledge about population diversity of broomrape in response to herbicides can help to better management this parasite. This experiment was carried out in a factorial with randomized complete block design with 3 replications under natural condition. First factor was broomrape populations and second factor was included active ingredient (a.i) of glyphosate (41%EC) at 21 & 41 ml ha-1 and sulfosulfuron (75%WG) at 27 & 50 g a.i ha-1, and 15, 20 and 30 ppm banzotiadiazol (BTH) sprayed 30, 40 & 50 days after transplanting or DAT. Density and dry weight reduction percentages of broomerape and yield loss of tomato were estimated. In all population except Oromieh 50 g a.i ha-1 sulfosulfuron was the best treatment (80% control). But only Behshahr broomrape population was completely controlled. Oromieh broomrape population was controlled 80%with 41 ml a.i ha-1glyphosate. All dosages of banzotiadiazol except 30 ppm a. i. ha-1, couldn’t control broomrape populations. | ||
