Thiencarbazone-methyl registered in first market

Annual sales potential of more than EUR 100 million for new corn herbicide

Bayer CropScience has reached a further milestone in the expansion of its successful product portfolio with the grant of the first regulatory approval for its new corn herbicide thiencarbazone-methyl in Romania. Thiencarbazone-methyl and the newly developed safener cyprosulfamide will be marketed in Romania in combination with the established active ingredient isoxaflutole as a ready-to-use-formulation under the brand name Adengo®. The market launch is scheduled for 2009. Further registrations for products based on thiencarbazone-methyl are expected in major European corn-growing countries, in the United States and in Argentina in the course of 2009.

“We are confident of achieving a global peak sales potential of more than EUR 100 million annually with this active ingredient”, said Dr. Rüdiger Scheitza, Member of the Board of Management of Bayer CropScience AG and responsible for Global Portfolio Management. After tembotrione and pyrasulfotole, this is the third new herbicidal active ingredient from the company’s successful research and development pipeline to reach market readiness since 2007.

Thiencarbazone-methyl controls monocotyledonous and dicotyledonous weeds in corn and displays a good balance between leaf action and soil action. The safener cyprosulfamide accelerates the decomposition of the herbicide in the corn plant, thus increasing its tolerability for the crop.

The spectrum of activity of thiencarbazone-methyl, a new sulfonyl-amino-carbonyl-triazolinine, covers a wide range of weeds. Several years of trials carried out worldwide with Adengo® have shown that it reliably controls even difficult weeds such as velvetleaf (Abutilon) and various species of pink weed. The product can be applied from pre-emergence to early post-emergence. Bayer CropScience recommends corn growers to use Adengo® as the new product combines good long-term action with outstanding biological performance. Once again, Bayer CropScience is setting new standards in modern, integrated weed management.
