AMVAC, Syngenta Team Up To Deliver Better Solutions For Soybean Growers


Syngenta Crop Protection, LLC (“Syngenta”) and AMVAC, an American Vanguard company (NYSE: AVD), have teamed up to promote the agronomic value of tank mixing Prefix herbicide from Syngenta with FirstRate herbicide from AMVAC for long-lasting and full-season weed control in soybeans.

The combination of Prefix and FirstRate herbicides provides unmatched flexibility and performance across all soybean trait platforms, including LibertyLink GT27, Enlist and Roundup Ready 2 Xtend soybeans. Together they provide unique flexibility and performance, resulting in better on-farm solutions for tough-to-control weeds.

Not only does Prefix plus FirstRate provide excellent crop safety with a flexible application window of preplant, preemergence and early postemergence, the combination delivers multiple modes of action to address tough-to-control weeds, such as waterhemp, Palmer amaranth, giant ragweed, common ragweed, morningglory, and marestail.

Soybean growers should talk to their trusted retailer to further discuss the weed control benefits of Prefix and FirstRate herbicides.

For more information on the agronomic value that Prefix and FirstRate can deliver in a soybean herbicide program, please talk to your local retailer.
