The product, by Arysta LifeScience, is applied to managed amenity turf for long-term selective control of broad-leaved weeds such as buttercup, clover, dandelion, deadnettle and dock.
Arysta LifeScience Product Development & Technical Manager for UK & Ireland, Don Pendergrast, said: "Dicophar is rather unique in that it contains four active ingredients, and this is why it is so effective in controlling such a broad range of troublesome weeds.
"We are delighted that the CRD has renewed the use of this product - a powerful tool for those looking to control weeds on golf courses, sports pitches and other large areas of turf."
Applied once a year, Dicophar contains the following active ingredients - 2-4D, MCPA, MCPP-P and Dicamba.
Pendergrast added: "Although applied only once a year, Dicophar has long-term efficacy. Trials have shown that for common weeds such as daisy, clover and dandelion, it offers control for up to three months."
