The first thing growers keen to grow Roundup Ready must do is complete a Monsanto accreditation course. [...] Next, farmers must sign a technical users’ agreement (TUA) which will capture specific planting details, including acreage, locations and planned sowing dates. They must also fill in a paddock resistance risk calculator, called the Paddock Risk Assessment Management Option Guide (PRAMOG), which will assess the risk of glyphosate resistance, especially in terms of ryegrass.
