Garden Chemicals

Sometimes gardeners turn to chemicals which can be hazardous if used, stored or disposed of incorrectly. Insecticides, herbicides and fungicides can help keep your garden looking great, but there are other techniques you can use to help your plants resist pests and disease.

‘Companion planting’ works on the theory that certain plants grow best when planted with others. You should include in your garden plants which have a naturally deterrent effect and plants that attract helpful insects. For more information about these techniques consult gardening books and magazines or your local gardening centre.

To reduce the risk from chemicals:

– purchase only the quantity you need to do the job and avoid storing quantities or mixtures of chemicals.

– store incompatible chemicals separately to avoid fires and averse chemical reactions

– keep oxidizing agents such as nitrate fertilizers and chlorine- based swimming pool chemicals separate from kerosene and from certain fungicides (EDBC) which, when wet, will generate heat

– make sure that all chemicals are properly labeled and stored in their original container, preferably with a child-proof cap. Keep well out of the reach of children and away from food

– Follow the mixing and application instructions on the label. Wear protective clothing when advised on the label and use any other necessary protective equipment, such as a respirator

– Apply the spray when the air is still to avoid the chances of spray damage to other areas of the garden or neighbouring properties

– Ask your local authority about the safest way to dispose of unused chemicals. They should not be poured into waste water or stromwater drains.
