Sinapis arvensis 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 S.arvensis on wheat and present economic thresholds. The trials were conducted in two different wheat fields between 1998-2001. The effect of different densities of S. arvensis 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-1. The economic thresholds of S.arvensis were between 1.02-5.38 plants m-2. According to results reveal that Florasulam+ Flometsulam and Tribenuron-methyl+Thifensulfuron- methyl to be convenient herbicides in the point of ecological view. |
