Weed identification procedures

  • Try and identify the plant yourself using available resources (see suggested resources below)
  • Ask an expert:
  • Use the MyPestGuide app to quickly identify pests and report your observations instantly to the Department of Primary Industries and Regional Development (DPIRD)
  • If you still can’t identify the plant, go to the WA Herbarium webpage for information on collecting and providing specimens to the Herbarium
  • If you think the weed you have found is a declared plant, contact the Pest and Disease Information Service or report it using the MyPestGuide Reporter app
