Sumitomo Chemical, Monsanto Company Strengthen Weed Management Collaboration in U.S.

Nov. 11, 2014

Sumitomo Chemical has reached an agreement with Monsanto Company to strengthen its strategic partnership with the leading U.S. seed and biotechnology company for the companies’ weed management collaboration in the United States, which was originally agreed upon in October 2010.

Monsanto develops diverse weed management recommendations for farmers to have effective, economical and sustainable weed control through the Roundup Ready PLUS® Crop Management Solutions platform. The Roundup Ready PLUS® platform includes Monsanto’s Roundup brand agricultural herbicides and offers farmers choices among residual herbicides for sound weed management.

Flumioxazin-based herbicide brands and other herbicides developed and marketed by Sumitomo Chemical, are effective in controlling glyphosate (active ingredient of Roundup® herbicide) resistant and tough-to-control weeds. These herbicides have produced significant results in managing resistant weeds in the United States since the herbicides of Valent U.S.A. Corp., a wholly owned subsidiary of Sumitomo Chemical, were included in the Roundup Ready PLUS® System from 2010. Under the agreement, a wider lineup of Valent products will be available in the Roundup Ready PLUS® platform. As a result, herbicides containing Flumioxazin recommended under Monsanto’s crop management platform will be available to a broader range of farmers.

Sumitomo Chemical, with this strengthened strategic partnership with Monsanto, contributes to help farmers solve various challenges in weed management and aims to further expand its crop protection chemical business in the United States.

  • A press release was issued in joint names of the three companies in St. Louis, Missouri, where Monsanto’s headquarters is located, at 9 a.m. local time on November 10 (at midnight Japan time on November 10).
