| Abstract | ||||
| Two field experiments were conducted at Sakha Experimental Station during 2004/2005 and 2005/2006 seasons to determine the effect of different sowing methods {dry method (afir) and dry method after false irrigation (hyrathy)} and weed control treatments (hand combing, imazethapyr, imazamox and butralin) on controlling dodder weed Cuscuta epilinum and on some growth characters of flax plants Linum usitatissimum, L. Results showed that the different sowing methods and hand combing were only suitable to avoid the competition of dodder weed due to their low weed population density. Also, the results showed that herbicides prevented the infestation with dodder up to 49 days in flax after treatments. All tested herbicides increased the plant height, number of capsules/plant, fiber yield and seed yield of flax crop in both seasons with different rations as compared to infested control treatment. Also, the results indicated that imazethapyr herbicide was least effective on chlorophyll content hence it caused 36.65% inhibition at 0.07 l/fed (twice) after 49 days from treatment, followed by imazamox at 0.4 l/fed (twice) 30.11% inhibition and butralin at 2.0 l/fed when used surface application at the same time. These results indicate that under heavy invested soil with dodder, it is possible to sowing after false irrigation ( hyrathy ) method with the application of herbicides i.e. butralin at 2.0 l/fed or imazamox at 0.4 l/fed (twice). These practices gave the highest reduction in dodder injury and increased flax yield and its components. | ||||
