Uptake and persistence of sodium monofluoroacetate (1080) in plants

The potential risks of 1080 poisoning to herbivorous species were examined by assessing the uptake and persistence of 1080 in two plant species, native New Zealand broadleaf and perenn...

Zusammenfassung:In New Zealand, baits containing sodium monofluoroacetate (1080) are applied widely to control possums and rabbits. The potential risks of 1080 poisoning to herbivorous species were examined by assessing the uptake and persistence of 1080 in two plant species, native New Zealand broadleaf and perennial ryegrass. A single toxic bait was placed on the soil in each of 42 randomly selected broadleaf and ryegrass replicates. Results showed that the toxin was rapidly taken up by ryegrass, with a mean maximum concentration of 0.08 ppm after 3 d. However, elimination of the toxin was just as rapid. The toxin was taken up more slowly in broadleaf and persisted longer, with a mean maximum concentration of 0.06 ppm after 10 d. Under the worst-case scenario simulated in the study, the poisoning of herbivores is not be considered serious, provided the control operations are executed carefully.
