@Steve818 @ACTBioSecurity
Are you aware of this re-emergence at original ACT site?

Hi @MichaelMulvaney , yes, I understand from the Rangers that it has a surprisingly persistent seedbank. They keep doing follow up. I think some residual flupropanate herbicide with a soil binder to stop it washing away, might help. Mal Copelin from City Services knows the technique. I will ask the Cotter Rangers to talk to him. @rangerstacey can you please email Mal Copelin for the details of the binder product and how it is mixed with flupropanate.

@steve818 thanks for the info, I'll do that. Just two plants found today in our regular checks. I have encouraged my team to use CNM to help with their plant ID, hence the upload today.
