Innovative solutions for pre and postemergence weed control in corn

Date:12-20-2007

Bayer CropScience presented a new crop protection solution for effective weed control in corn at the 62nd North Central Weed Science Society (NCWSS). This scientific meeting was held in St. Louis, Missouri, USA, on December 10 through 13, 2007. The company is now preparing to launch a new herbicidal mixture for preemergence weed control in corn: a combination of the active ingredients thiencarbazone-methyl and isoxaflutole.

Thiencarbazone-methyl is a new sulfonyl-amino-carbonyl-triazolinone (SACT) from Bayer CropScience for preemergence weed control in corn. The two active ingredients thiencarbazone-methyl and isoxaflutole complement each other and will be combined with the new proprietary herbicidal safener cyprosulfamide to provide additional crop safety. This new premixture can be applied from prior to planting through the second leaf-collar stage of corn. “Field studies have proven the excellent performance of thiencarbazone in combination with isoxaflutole against key monocot and dicot weed species in corn”, explained Dr. Brent D. Philbrook, researcher at Bayer CropScience LP, located in Research Triangle Park, North Carolina. Market introduction is expected in the USA in 2009 pending regulatory approval.

“Bayer CropScience is well positioned in herbicides. Our aim is to further expand our leading position by launching products with the new safener technology, in particular in corn, one of the major crops worldwide”, said Christophe Dumont, Head of the Strategic Business Entity Herbicides at Bayer CropScience. “We have four new herbicidal substances in late-stage development, and they are scheduled for market introduction between 2008 and 2012”, he added. Two further recent herbicidal active ingredients, tembotrione and pyrasulfotole, are scheduled for launch in the United States in the very near future.
