<I>Sinapis arvensis</I> is one of the most prevalent weed species in wheat in the Middle Black Sea Region of Turkey. In recent years integrated weed control management practices have been increased as a result of disadvantages of herbicides usage in agriculture. The study was carried out to estimate competitive effects of <I>S.arvensis</I> on wheat and present economic thresholds. The trials were conducted in two different wheat fields between 1998-2001. The effect of different densities of <I>S. arvensis</I> was calculated as yield losses compared with control plots in percentage. The percentage yield losses were correlated to the weed density by using a non-linear regression model for both weed species. The yield losses of 36.87% were observed at densities of 32 plants<SUP>-1</SUP>. The economic thresholds of <I>S.arvensis</I> were between 1.02-5.38 plants m<SUP>-2</SUP>. According to results reveal that Florasulam+ Flometsulam and Tribenuron-methyl+Thifensulfuron- methyl to be convenient herbicides in the point of ecological view. |
