Our service

Grow Help Australia provides:

  • tests for the presence of pests and pathogens of plants
  • limited tests of seeds—fungal pathogens only
  • tests of growing media, soil and water for limited pathogen groups (e.g. Phytophthora)
  • plant pathogen testing to support accreditation schemes and export requirements.

Our process

This information explains the process of how to submit a sample for testing to Grow Help Australia.

We often take 2–3 weeks to complete your sample (although we make every effort to complete them quickly), but whenever possible we will provide you with preliminary results. We will keep all information confidential.

At the end of the testing process, you will receive:

  • a final written report that includes test results
  • interpretations and diagnosis
  • practical advice (wherever possible) on how to remedy any issues identified through the testing results.

Also, we provide online resources that may assist you to determine if your crop is being affected by a pest or disease, and whether it's worthwhile submitting a sample to confirm what is, or is not, affecting the crop.

Testing plants for chemicals

Grow Help Australia does not test plants for the presence of chemicals. For example, we don't test for:

  • herbicides
  • insecticides
  • other products
  • nutrient analysis.

  • identify weed seeds present in a seed batch
  • determine the variety of the plant
  • identify what species of roots is present.

Private laboratories can provide these services. Search online for their details using the term 'laboratory Australia' and also include the following or similar search terms:
