摘要

Two field experiments were conducted at the Agricultural Experimental Station of the National Research Centre at Shalakan, Kalubia Governorate, during the two seasons 1994/1995 and 1995/1996 for studying the effect of some herbicides on two wheat (Treticum aestivum L.) cultivars and associated weeds. The herbicides, Bromoxynil/Clodinafop-propargyl at a concentration 135, 225 and 315 g a.i./fed., as well as, Metosulam at 8 g a.i./fed., Diflufenican/Bromoxynil at 220 g a.i./fed. Hand pulling gave the best control of total annual weeds. The higher values of chlorophyll a, b, carotenoids and total pigment were obtained from hand pulling treatment, Bromoxynil/ Clodinafop-propargyl at 135 g a.i./fed., Metosulam at 6, 8 g a.i./fed. and Diflufenican/ Bromoxynil at 165 g a.i./fed. The lower values of chlorophyll a, b, carotenoids and total pigment, were obtained from the unweeded treatment and the highest rate (315 g a.i./fed.) of Bromoxynil/Clodinafop-propargyl, as well as, Metosulam at the lowest dose (4 g a.i./fed.). Giza 164 gave higher grain yield than Sakha 69. Also, results showed that the highest values of these characters was obtained with hand pulling, Bromoxynil/Clodinafop-propargyl at 135 g a.i./fed., Metosulam at 8 g a.i./fed. and Diflufenican/Bromoxynil at 165 g a.i./fed. The higher grain yield of the two cultivars were observed, when combined with hand pulling, Bromoxynil/Clodinafop-propargyl at lower dose (135g a.i./fed.), Metosulam at highest dose (8 g a.i./fed.) and Diflufenican/ Bromoxynil at medium dose (225 g a.i./fed.) in the two seasons. Giza 164 was the best when the manual weed control method (hand pulling) was used, whereas, when chemical weed control was used it prefers Sakha 69.
