The Chemicals Regulation Division (CRD) has announced the final sales date for desmedipham-containing products following the EU Commission’s decision in 2018 to withdraw approval for the active substance. This means sugar beet growers intending to use Bayer’s range of Betanal herbicides in 2020 have until the end of 2019 to order product as sales will no longer be permitted after this date. Growers then have until 1st July 2020 to use up or dispose of any remaining stocks.
Desmedipham has been relied on to provide lasting residual control of a range of weeds in all beet crops since it was first introduced in combination with phenmedipham in Betanal E in 1968. Over time other actives, such as ethofumesate and lenacil, have been included to expand and improve weed control, but desmedipham and phenmedipham have served as the basis for efforts to deliver effective weed control.
The European Commission’s decision means 2020 will be the last season for, among others, Betanal maxxPro (desmedipham + phenmedipham + ethofumesate + lenacil), Betanal Elite (desmedipham + ethofumesate + phenmedipham) and Betanal Turbo (desmedipham + phenmedipham).
“Betanal maxxPro and the family of Betanal products have been widely used across Europe for many years. They have provided robust weed control, flexibility of use and excellent crop safety,” says Edward Hagues, Bayer campaign manager for root crops.
“As market-leading products we know their withdrawal will be a blow to many growers who have relied on Betanal-based products for their weed control in sugar beet. That's why we have brought forward production schedules to help growers make the transition to non-desmedipham containing products a little bit easier,” he adds.
“Those wanting to maintain an effective and flexible approach to weed control in 2020 should ensure they have sufficient Betanal maxxPro in stock to meet their needs before the New Year as desmedipham-containing products cannot be sold after this time,” he says.
The European Commission decision not to renew the approval for desmedipham came into force on 1st July 2019. Under the rules of the World Trade Organization (WTO), all member states are required to give 12-months’ notice of their intention, hence the use-up date of 1st July 2020.
