The sodium salt, sodium fluoroacetate, is used as a pesticide. It inhibits the aconitase step of the citric acid cycle.[1] Natural occurrenceFluoroacetate occurrence in Gastrolobium speciesGastrolobium is a genus of flowering plants in the family Fabaceae. There are over 100 species in this genus, and all but two are native to the south west region of Western Australia, where they are known as "poison peas". Gastrolobium growing in south western Australia are unique in their ability to concentrate fluoroacetate from low-fluorine soils.[8] Brush-tailed possums, bush rats, and western grey kangaroos native to this region are capable of safely eating plants containing fluoroacetate, but livestock and introduced species from elsewhere in Australia are highly susceptible to the poison,[9] as are species introduced from outside Australia, such as the red fox. The fact that many Gastrolobium species also have high secondary toxicity to non-native carnivores is thought to have limited the ability of cats to establish populations in locations where the plants form a major part of the understorey vegetation.[10]The presence of Gastrolobium species in the fields of farmers in Western Australia has often forced these farmers to 'scalp' their land, that is remove the top soil and any poison pea seed which it may contain, and replace it with a new poison pea-free top soil sourced from elsewhere in which to sow crops. Similarly, after bushfires in north-western Queensland, cattlemen have to move livestock before the poisonous Gastrolobium grandiflorum emerges from the ashes.[11] See also
