Briers has broadened its sales coverage with the appointment of two new agents at the start of March.
Jim Turner is responsible for south Cambridgeshire, Bedfordshire, Essex, Hertfordshire, north London and south Buckinghamshire.
Cheryl Wilkins is covering Norfolk, Suffolk, Northamptonshire, Lincolnshire, Leicestershire, Derbyshire and Nottinghamshire, as well as north Buckinghamshire.
Mr Turner and Ms Wilkins both work for Bayer and will also be the company's agents for the above areas.
Mr Turner said: "We'll be calling on our existing customer base that we've built up with Bayer. The Briers brand will be offering some real competition to its competitors."
Ms Wilkins said: "We'll be getting the Briers name back out there and building up even more confidence in the brand."
