Monsanto launches online weed resistance program

Monsanto is launching an online Weed Resistance Risk Assessment Program for growers who use Roundup Ready weed control technology.

Located on the Web at, the one-of-a-kind risk assessment program was created to help farmers gauge the risk of developing glyphosate-resistant weeds in their fields.

In addition, it offers best farming practices to manage those risks without limiting yield potential.

Monsanto developed the program in cooperation with seven universities: Purdue University, University of Nebraska, Southern Illinois University-Carbondale, the University of Missouri, Michigan State University, North Carolina State University and Iowa State University.

“We are proud to support our farmer customers and provide them with this informative Web-based risk assessment program to help them obtain practical weed management options when utilizing glyphosate technology,” said Rick Cole, Monsanto corn technology development manager.

“We believe this tool will provide them a valuable resource to measure the weed resistance risk in each field and give them advice for the management of the risk from academic experts in the agriculture industry.”

With the help and advice of university weed science experts, 10 brief questions were developed as the basis for the farmer field-by-field assessment.

After participants answer the field-related questions, they are assigned a risk rating score.

Then, their three highest scoring questions are addressed with corresponding best farming practices designed to help lower their weed resistance risk.

In addition to the situation-specific recommendations, users have access to weed management guides for tough-to-control weeds, academic weed resistance tip boxes and other university weed specialist articles.

“With Roundup Ready technology established as the foundation for weed control in soybeans, cotton, canola and corn, we want to ensure growers are confident they can enjoy the benefits of the technology year after year and minimize the risk of developing weed resistance to glyphosate,” said Cole.

The Web-based tool is the first interactive risk assessment component of Monsanto's overall glyphosate stewardship plan. Monsanto continually evaluates its recommendations for effective weed control and provides alternate weed control recommendations to control tough or resistant weeds.

Monsanto also sponsors research, often through partnerships with university cooperators, on weed resistance and the company develops best management practices for different cropping systems.
