UK: Linuron replacement for ornamental bulb growers

The withdrawal of linuron earlier this year left a large gap in weed control options for many growers, including ornamental bulb growers.

As metobromuron has shown to be a reliable alternative to linuron, the AHDB Minor Use team has worked closely with Belchim and CRD (Chemicals Regulation Division) to successfully deliver authorisations for its use in ornamental bulbs.

New herbicides, especially for use during the dormant period in the autumn, have been a high priority for ornamental bulbs, particularly following the withdrawal of linuron.

The four new Extensions of Authorisations for Minor Use (EAMUs) are for Praxim, Inigo, Lianto and Soleto. The authorisations run until the end of November.

James Cheesman, Crop Specialist for Belchim UK, said: “The loss of linuron earlier this year has left a gap in the spectrum of weeds which can be controlled in ornamental bulbs, such as Narcissi.

"The new EAMU for Praxim (metobromuron) in the crop gives ornamental bulb growers a welcome new option. Metobromuron was first registered in 2015 as a broad spectrum grass and broad-leaved weed herbicide for use pre-emergence in potatoes, and has proven to be a reliable tool ever since”.

Praxim was tested as part of the SCEPTREplus herbicide trials in narcissus. The full report will be available soon.
