Abstract

Two field experiments were conducted in a research experimental farm in Rasheed region, Behaira Governorate during two wheat growing seasons of 2007 and 2008 winter to evaluate the performance of certain herbicides namely: bromoxynil-octanoate (Brominal® 24% EC), tribenuron-methyl (Granstar® 75% DF), diflufenican+isoproturon (Panther® 55% SC) and florasulam+flumetsulam (Derby® 17.5 % SC) at rates of 1000 ml, 8 g, 600 ml and 30 ml, respectively/feddan. The evaluated herbicides are selected against the broad leaved weeds and therefore they have been used to overcome the most harmful weeds[ wild beet (Beta vulgaris), nettleleaf goosefoot (Chenopodium murale) and toothed bur clover
(Medicago hispida)] found in the fields of wheat (Triticum aestivum var. Sakha 61). Furthermore the effect of the evaluated compounds on wheat yield was considered. The data showed that the superior effect was achieved by tribenuron-methyl (Granstar®). Meanwhile it is also recorded the highest percentage of wheat yield increase, followed by bromoxynil-octanoate (Brominal®), florasulam + flumetsulam (Derby®) and diflufenican + isoproturon (Panther®). All the applied treatments increased the weight of 1000-grains over the weedy check treatment in both seasons of 2007 and 2008.
