Try natural alternatives to chemical products (e.g. compost is
an excellent fertiliser, and pyrethrum, made from the dried flower
heads of some chrysanthemums, is a powerful pesticide for aphids
and mosquitoes).
Avoid using chemical products during windy conditions or when
rain is forecast.
Apply them sparingly, i.e. no more than the recommended amounts.
Use herbicide with a wand applicator to avoid spray drift.
Only use chemical products near drains or natural waterways that
are approved for that use; see label conditions and near-water
application handbook for more details).
The EPA Guidelines for Responsible
Pesticide Use (870KB PDF) provide further
advice on pesticide use issues for all pesticide users.
The EPA has also developed three practical handbooks to provide
more specific pesticide use guidance:
Use a slow-release fertiliser in areas where the potential for
contamination of water is high, such as on sandy soils, steep
slopes, compacted soils and the edges of lakes, creeks and dams.
If you decide to use a professional lawn and garden care service,
select a company that is committed to minimising the use of fertilisers,
herbicides and pesticides, and to disposing of them appropriately.
Do not pour leftover products down any drain or indiscriminately
onto the garden - take them to your nearest Household
Hazardous Waste Collection Facility.
