Picking the Right Products
SGA promotes non-chemical methods to prevent pest and disease problems in the garden as the first line of defence, but there are times when gardeners will want to choose a chemical solution. When faced with this decision, then choose one of the safe and low environmental impact alternatives from our Garden Product Guide. Mother Nature will thank you for it! All available products have been given a rating of 1 – 6 Stars and all that are listed here have achieved a 6 Star rating. And all products are periodically re-assessed to ensure that any changes to formulations, packaging or active ingredients have been accounted for. Oh, and just so you know, SGA does not endorse any product or receive financial benefit from the sale of any of these products.
About the Garden Product Guide
In conjunction with the University of Melbourne (Burnley), SGA has developed the first rating system for garden chemicals, fertilisers and soil conditioners in Australia. The assessment of over 1000 products is based on regulatory poison schedule ratings, such as the Standard for the Uniform Scheduling of Medicines and Poisons (SUSMP) rating, and on the active ingredients derived from the material safety data sheets (MSDS). The environmental impact rating information that determines ecotoxicity, such as soil mobility, persistence, bioaccumulation, potential to pollute waterways and toxicity to non-target organisms is derived from authoritative sources such as government departments, international research organisations and current scientific research publications.
Also taken into account are factors which may pose risks to users or children: the capacity of the packaging to prevent inadvertent exposure and whether the mode of delivery e.g. as an aerosol or powder might increase the likelihood of inhalation of toxic material.
Scores for all criteria are then used to give a rating on a 6 Star basis, letting consumers know exactly how safe their chosen product is and how it may impact on the immediate and wider environment and the health of our planet, both now and in the future.
The assessment system, at this stage, does not take into account a Life Cycle Analysis (e.g how much energy was used in making the product?) apart from product packaging. New products and changes to existing garden products are identified through manufacturer or distributor websites or notification from their representatives.
You will notice that there are only a few products that have achieved a 6 Star rating. Many more have a 5 Star rating with relatively low safety and environmental impacts. Currently we are listing the 6 Star-rated products for pest and weed control, plant diseases and some miscellaneous products (click on the linked headings below) while, over the next few weeks, we complete the ratings for fertilisers, soil improvers and wetting agents.
Then a few months, we will make the full list of garden product ratings available as a web App with details of their active constituents, soil mobility and persistence and bioaccumulation along with information on their toxicity for humans, aquatic organisms and bees.
