Metaldehyde, a long-established specific molluscicide for land slug and snail control, is not satisfactory under moist weather conditions. The search for a more effective molluscicide has resulted in a laboratory screening technique, simulating natural conditions, by which experimental baits are presented to various species of land molluses. The brown garden snail, Helix aspersaMuller and the European black slug Arion ater (L.), are laboratory reared for the tests, while other species are field collected in season. five experimental carbamate materials have shown outstanding activity against land molluses to date: Bay 37344 (4- (methylthio) -3,5-xylyl methylcarbamate), UC 20047A (Tranid® (exo- (5-chloro-6-oxoendo 2-norbornanecarbonitrile 0- (methylcarbamoyl) oxide), EP-332 (m [[ (dimethyl amino) methylene]amino] phenyl methylcarbamate hydrochloride) , EP-316 (m-cym-5-yl methyicarbamate), and IN -1179 (methyl N-[ (methyicarbamoyl) oxy] thioacetimidate). All established chlorinated hydrocarbon and organophosphate pesticides tested have shown little or no toxicity to slugs and snails.
