The following information comes from the Department of Primary Industries and Regional Development (DPIRD)

DPIRD is beginning its annual surveillance program on 25 November 2025, which will continue until late January, early February 2026.

DPIRD Biosecurity officer Zara Matthews said the department was undertaking the first round of surveillance and control for pokeweed on properties in and around Balingup and Mullalyup

“Now is an ideal time to identify the poisonous plant (scientific name Phytolacca americana) as it will be in flower,” Ms Matthews said.

“DPIRD inspectors will be accessing both private and public property to look for and control all pokeweed plants prior to them forming berries and setting seed this summer.

“We appreciate the help and cooperation of landowners to eradicate and stop the spread of this toxic declared weed.”

Pokeweed, including its leaves, roots and berries, is toxic to both humans and animals and should not be eaten or handled. It is an environmental weed and can also affect agricultural activities by contaminating produce. Pokeweed looks similar to inkweed, which is widespread in the Southwest, but grows taller – up to 2.5 metres – and has larger leaves and drooping berry stalks. It has bright green leaves up to 40cm long on a smooth purplish stem. White to magenta flowers form in elongated clusters hanging from branches.

Images to assist in the identification of pokeweed are available in the Biosecurity Alert linked below, and if you suspect you have seen pokeweed you can take photos and make a report to DPIRD by using the MyPestGuide™ Reporter app. Do not collect the seeds, berries or leaves as they are all poisonous. Alternatively, the department’s Pest and Disease Information Service can be reached at 9368 3080 or via email padis@dpird.wa.gov.au.
