The future use of the herbicide dicamba, a key weed control tool for no-till soybean and corn growers, is in jeopardy as it faces a series of regulatory challenges at the Supreme Court, EPA, and state legislatures. Concerns over dicamba's health and environmental impacts have led to proposed bans and new restrictions that could significantly impact how farmers manage weeds in their no-till operations.

Why it matters

Dicamba has become a critical component of weed control programs for the majority of U.S. no-till soybean and corn growers, who rely on it to manage herbicide-resistant weeds. Any disruption to dicamba's availability could force farmers to find alternative, potentially less effective weed control strategies, threatening the sustainability of no-till practices.

The details

A recent federal court ruling vacated the EPA's 2020 approvals of dicamba-based herbicides sold by major manufacturers like Bayer, BASF, and Syngenta. This decision has sparked a flurry of regulatory activity, with the Supreme Court, EPA, and state legislatures all poised to make decisions in 2026 that could further restrict or ban the use of dicamba. Proposed changes include removing over-the-top applications in soybeans, limiting application timing, and imposing additional safety measures.

  • In 2020, a federal court vacated the EPA's approvals of several dicamba herbicides.
  • Decisions from the Supreme Court, EPA, and state legislatures on the future of dicamba are expected in 2026.

What they’re saying

“The USDA's announced $700 million commitment to regenerative ag is a big deal for the no-till and soil health movement.”

— Monte Bottens, No-till farmer and Ag Solutions Network co-founder

What’s next

The Supreme Court, EPA, and state legislatures are expected to make decisions in 2026 that could further restrict or ban the use of dicamba herbicides, forcing farmers to find alternative weed control strategies.

The takeaway

The future of dicamba, a critical tool for no-till weed management, is uncertain as regulators weigh concerns over its health and environmental impacts. Farmers may need to prepare for potential disruptions to their weed control programs, which could threaten the sustainability of no-till practices if alternative options prove less effective.
