Sir,
In response to the letter from Tim Liddon of Tilhill Forestry (The Oban Times, April 27), many pesticides that are now banned – eg, organophosphates – were once authorised and approved by government and scientific authorities.
Neonicotinoids are already banned in some European countries, and are shortly to be banned by the EU. Pesticides are designed to kill, and neonicotinoids destroy acetylcholine in nerves and the brain.
