BASF announced that its herbicide portfolio maintained performance throughout the 2026 crop season in Iowa. Persistent heavy rains throughout the season created challenging field conditions that complicated standard weed control efforts.
Why it matters
Frequent rainfall during the growing season accelerated weed growth while limiting the ability of farmers to manage fields effectively. BASF indicated its products provided reliable control despite these difficult environmental obstacles.
BASF confirmed that Surtain corn herbicide and Liberty Ultra soybean herbicide maintained efficacy throughout the rainy 2026 crop season. These results were measured against a background of heavy seasonal precipitation that otherwise hindered weed management.
