Innovative solutions for pre and postemergence weed control in corn

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.
