Entity of the month
Slugs cause significant damage to plants and crops, particularly cereals, potatoes, and oil seed rape and are regarded as arable farming's number one pest [1]. Metaldehyde (CHEBI:81931) is a cyclic tetramer of acetaldehyde whose crystal structure was first determined in 1936 [2]. It initially found use as a solid fuel firelighter, sold as 'Meta-Fuel' but nowadays, it is used as a molluscicide for the control of slugs and snails in agricultural fields and domestic gardens. It kills slugs and snails by disrupting their ability to produce mucus thereby reducing their digestion and mobility thus making them susceptible to dehydration [3].
