About WiseGardening

About WiseGardening – Choices to Protect You and the Planet

About WiseGardening provides background information for WiseGardening – why it has been created, why you will find it useful and the principles underpinning its ratings of garden chemical products for their risks and safety to you and the planet.  Wisegardening also includes other choices for controlling garden pests and disease.

Its Purpose

WiseGardening is designed to enable you to make informed decisions about how you address garden problems i.e. disease, pests and weeds.  WiseGardening assesses then rates garden chemical products commercially available in Australia that have been manufactured to deal with these problems and presents alternative non-chemical approaches to address them. Similar guides are available for specific areas overseas, such as Europe or the USA (www.growsmartgrowsafe.org) but these are not tailored for products and formulations used in Australia.

WiseGardening has been developed to help all of us achieve more international sustainable development goals through reducing some of the impacts that our society has had on the planet. SGA promotes natural, non-chemical methods to prevent and treat pest, disease and weed problems as the first line of defence.  However, there are times when a chemical product is a necessary choice.

As you might expect, since these products are termed pesticides and weedicides where the suffix “icide” means “kill”, many chemical products, as well as killing their targets, carry risks to users and other species on our amazing planet – even when they are used very carefully.

Manufacturers alert users to these risks on their product labels, instructions for use and Safety Data Sheets.  However, when consumers buy products they may not consult these sources in-store to compare products and may not even read or understand the advice provided before using the products.

WiseGardening aims to provide, in one place, easily accessible, evidence-based information about potential risks of associated products and their ingredients or alternatives to solve particular garden problems.

By using WiseGardening to help make your gardening decisions you are contributing to increasing social and environmental sustainability.

WiseGardening does not:

  • Provide comment on product effectiveness in achieving its purpose, or
  • Endorse, or condemn any product, manufacturer, brand or supplier.

Why Use WiseGardening?

The broad community which uses chemical garden products has a right to know risks associated with their use.  These products can affect:

  • Users if they come into contact with the product or breathe in vapours – some products are quite toxic.
  • Species that visit or live in our gardens – birds, bees, fish, worms, frogs and a range of mammals, such as pets, especially if the chemicals persist in the soil.
  • Aquatic species as well as fish – if the chemicals can be washed through the soil winding up in streams and other waterways they may harm not only fish, but also other aquatic organisms.

So knowing which product to select, when faced with a plethora of ‘plantastic products’ in the local garden centre, or knowing if we should still use old products with stained labels stored in our garden sheds, can be very daunting. In order to minimise these risks we all need to know what they are.

Principles Underpinning WiseGardening

  1. Transparency – We aim to augment the availability of information that manufacturers provide about their garden products. To this end, WiseGardening uses publicly available information from many sources. (See Our Ratings and Assessment Process link)
  2. Accuracy – This means that assessments are systematic and based on robust scientific research from reputable sources. However, sometimes this information is unavailable due to commercial considerations and sometimes due to out of date or incomplete information. Where little or no information about a product or ingredient is available this is indicated in WiseGardening.
  3. Independence and objectivity – No preference to any products or for any manufacturer is given.
  4. Comprehensiveness and inclusiveness – We aim to include all chemical garden products available in Australia for non-agricultural use. Products available in other countries are not included since, elsewhere, they mostly differ in names and ingredients. We have also not restricted assessments to commercially manufactured products and have included alternative mostly non-chemical approaches. If a product is missing it is not intentional; we aim to include all relevant products.  We have not considered home-made mixes of household chemicals since it is not possible to obtain any accurate information about ingredients used in these preparations.
  5. Currency – The assessment is routinely updated and products are frequently assessed to determine if their ingredients, or details in the product description, have changed. Information sources for ingredients are also frequently checked to ensure the latest publicly available scientific assessments are used. As products are often discontinued by manufacturers, we retain these products in our database so that assessments can be made of new products against discontinued products across product types. Sometimes, new products have the same name as a discontinued product but have a different composition.  We aim to ensure that assessments of current products are no older than 1 year.
  6. Ease of Use – The rating system should provide users with data that is accessible, able to allow comparison and easy to use. Data entry for WiseGardening has been structured so that assessment is performed automatically, drawing on ingredient information within the database.
  7. Compatible with UN Sustainable Development Goals –
    • Goal 3: Ensure healthy lives and promote well-being for all at all ages
    • Goal 12: Ensure sustainable consumption and production patterns
    • Goal 13: Take urgent action to combat climate change and its impacts
    • Goal 15: Sustainably manage forests, combat desertification, halt and reverse land degradation, halt biodiversity loss
  8. Fostering productive change – encouraging the community and industry, through education, to engage with the change required to achieve a safer and more sustainable world.

Who are We?

Sustainable Gardening Australia (SGA) is a not-for-profit, non-government organization with a strong interest (passion) for enabling gardeners to grow their own food, protect their health and that of the planet and all that is naturally on it.  It has charitable status under the federal government’s Register of Environmental Organisations and is registered with the Australian Charities and Not-for-Profit Commission (ACNC).

WiseGardening was initiated over 20 years ago as a collaboration between SGA, Paul Gibson-Roy from Burnley Horticultural College (now part of the University of Melbourne), the garden centre Bulleen Art and Garden and local government.

Since 2016, our SGA team has further developed and refined WiseGardening to make it available as part of our web presence.

The Team

Dr. Sharron Pfueller (biochemistry, cell biology, environment, sustainability),  Dr. Colin Allison (chemistry, environment, climate change, database development), Angelo Eliades (horticulture, permaculture, toxicology), Bridey Oliver (horticulture), Jane Rollinson (horticulture, information mapping), Michelle Dyason (natural methods of pest control).

Since 2019 the WiseGardening development has been supported by funding from the Telematics Trust as a project to provide community education.

Go to WiseGardening ratings


WiseGardening rates garden chemical products for effects on health of humans and planet based on scientifically determined and publicly available data.  Data on products and ingredients used to create WiseGardening are the scientifically estimated and publicly reported risks to the health of humans and a range of other living organisms.  Also shown are other important chemical properties.  For details of how ratings are derived see Our Assessment and Rating Process

Remember: these risks are very important if products are used unwisely.  Always use products strictly according to manufacturers’ instructions on labels and associated documentation.

Notes on Using WiseGardening

WiseGardening is sortable using the Search and Filter boxes.  The Search function can show information not visible on this page e.g. particular susceptible pests.  For some searches a full word such as “fungus” may not find many choices, but the beginning “fung” will show more because many entries might be for “fungicide”. Therefore, for some searches fewer letters may be more effective.

Note that the ingredient risks are based on pure ingredients so the risks are independent of the amount of ingredient in the product.

Some products with high star ratings still show some ingredient risks or other undesirable product characteristics. These products have received a high star rating because aspects of product packaging or being pre-mixed (i.e. not requiring dilution before use, or having robust packaging) reduce the likelihood of spills which could be harmful.
