As part of the velvetleaf response MPI tested a number of imported fodder beet seed lines and detected small quantities of corn buttercup (Ranunculus arvensis).
It was not the more invasive pest buttercup, giant buttercup, but rather a smaller buttercup native to Europe.
“This is not a threat,” MPI velvetleaf response incident controller David Yard said.
A risk assessment determined the corn buttercup was already established in New Zealand.
“It presents no more of a biosecurity risk than other ranunculus species already present in NZ and no further action is being taken,” he said.
DLF Seeds general manager Tom Bruynel said the company, responsible for importing the contaminated fodder beet seed lines, identified the buttercup at trace levels only.
“We are being upfront with customers and giving them the information and letting them know what to do and most people are happy with that and still selling the seed,” Bruynel said.
