Metaldehyde Conference

It is estimated that losses of £45m – £100m per annum could occur in agriculture if molluscicides were not used.

Date/Time: Thursday 13th September 2018

Venue: FERA Science Ltd, York YO41 1LZ

Current pellets can cause pollution, and improvements to their design are urgently required.

The molluscicide metaldehyde is frequently detected in surface water at concentrations greater than predicted during the regulatory approval process, and it presents a challenge for water treatment.

The meeting’s aim is to better understand these multi-facetted challenges to industry, farmers, regulators and the water industry, and to discuss the science required to give better and safer slug control.

Keynote Speakers: Ian Boyd (Defra) and John Haley (UKWIR)
