Syngenta aims Acuron Flexi at US
Syngenta plans to introduce a new combination of its herbicide, bicyclopyrone, with two unnamed active ingredients in the US next year as Acuron Flexi. The as yet unregistered product would provide pre- and post-emergence residual control of "difficult" weeds in maize, the company points out. Acuron Flexi would combine ais with complementary modes of action to deliver a multi-targeted approach to weed control. This is especially important as weed resistance is expanding and weeds such as giant ragweed (Ambrosia trifida), waterhemp and Palmer amaranth (both Amaranthus spp) are becoming more difficult to manage, Syngenta notes. The company received US approval for Acuron (bicyclopyrone 7.1 g/litre + mesotrione 28.5 g/litre + atrazine 120 g/litre + S-metolachlor 257 g/litre) in April, with a limited introduction planned for this year.
