Successful Farming's Editorial Guidelines Published on February 9, 2024 Close The EPA has registered Surtain, a new field corn herbicide from BASF. The solid encapsulated premix formula may offer control or suppression of 79 broadleaf and grass weeds. With a focus on residual control, Surtain applications can be made from pre-plant to V3. “Every year, growers spend millions of dollars to control weeds in corn fields due to increased herbicide resistance,” said Scott Kay, vice president of U.S. agricultural solutions at BASF, in a news release. “Surtain herbicide’s unique chemistry targets weeds at their most vulnerable state, providing excellent control of even the most troublesome weeds facing corn growers today.” BASF developed Surtain with difficult weeds such as Palmer amaranth, waterhemp, and giant ragweed in mind. The active ingredients in Surtain are Group 14 saflufenacil and Group 15 pyroxasulfone, reducing farmer reliance on HPPD inhibitors. The product can be tank mixed with herbicides, liquid fertilizers, adjuvants, and additives to provide flexibility. Surtain is approved for use, subject to state approvals. To learn more, click here.
