AMVAC and Syngenta announce benefits of Prefix and FirstRate herbicide tankmix

Date:04-22-2020

Syngenta Crop Protection and AMVAC, an American Vanguard company, are teaming up to promote the agronomic value of tank mixing Syngenta’s Prefix herbicide with FirstRate herbicide from AMVAC for full-season weed control in soybeans.

Company officials say the combination of Prefix and FirstRate herbicides provides 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, according to company officials.

Prefix plus FirstRate provide excellent crop safety with a flexible application window of preplant, preemergence, and early postemergence, according to company officials. They add that the combination delivers multiple herbicide sites of action to address tough-to-control weeds, such as waterhemp, Palmer amaranth, giant ragweed, common ragweed, morningglory, and marestail.
