Forefront T and Halcyon are the most effective products for managing weeds such as docks, nettles, thistles, buttercups, dandelions and ragwort. These products should only be applied to established grassland where cattle or sheep are grazed. Herbicide residues in grass that is used for zero grazing, silage, hay or haylage may harm sensitive crops if the resulting manure/slurry is used as fertiliser.

Renowned herbicides such as Astrokerb^® and Kerb^® Flo contain propyzamide and are the cornerstones of many herbicide programmes. They are key to controlling grassweeds, especially blackgrass and ryegrass in oilseed rape, and with no known resistance, propyzamide can help manage and reduce the burden of these weeds across the rotation.

After a heavy rain event there is a risk of propyzamide attached to soil particles getting washed into surface water. Appropriate planning, management and adoption of stewardship practices must be followed to mitigate this risk.

Oilseed rape growers are urged to consider the actions they can take to protect watercourses. Field selection, tramline placement and buffer zones can all play an important role in effective risk mitigation.

The government review of authentic, legal products undergo extensive testing and strict evaluation. These essential regulatory processes serve to ensure that only safe and high-quality products are commercialised.

Unfortunately, there are a growing number of counterfeits and illegal products being placed on the market. Not only do these illicit products compromise sustainable agriculture, but they also pose an unacceptable risk to health - human and environmental.

At Corteva, we have a global anticounterfeiting strategy to protect our customers and our brands.
