Corteva Agriscience™ has just gained approval from the UK's regulatory authority for pesticides, Chemicals Regulation Division (CRD), for two new selective herbicides for use on grassland.

Founded on the rich heritages of Dow, DuPont and Pioneer, Corteva Agriscience is one of the largest crop protection companies in the world with an annual research and development budget of more than $1.3 billion.

Robin Bentley, Category Marketing Manager at Corteva Agriscience, says: "It costs around $300 million to develop a new active and navigate it through the development process to secure approvals around the world.

"It's been nearly 20 years since aminopyralid (Forefront^® T) was introduced - the last new active for use on grassland. It is truly exciting to be presenting these two new active ingredients: Rinskor™ and Arylex™. Each are presented as new product formulations and reflect new potential use areas."

Rinskor is the basis of ProClova® XL, a highly effective broad-spectrum clover-safe weed control solution which enables farmers to successfully establish and preserve clover populations in grassland and realise the benefits of its inclusion which range from nitrogen fixation, improvement of soil structure and biodiversity improvement.

ProGrass™ contains Arylex and brings long-lasting control of tough-to-control key broad-leaved weeds in established grassland.

Robin says: "Both products will be available this spring and represent innovation which will help maximise the productivity of grassland and grass plus clover. Corteva will share more details on where and how to use the products this spring."
