The Use of Garden Chemicals
When used for their correct purpose in a responsible manner, pesticides have a useful role in tackling some pests, diseases and weed problems. The Royal Horticultural Society, through its advisory service at Wisley Garden, its website and at RHS Shows, offers advice on the identification of pests, diseases and weeds, and the appropriate measures that can be taken to control them. It will also advise when treatment is not required, thus saving the unnecessary use of chemicals.

A summary of RHS policy
1) When used correctly in a discriminating way the RHS recognises that insecticides, fungicides and herbicides are useful and effective tools in a garden.
2) The RHS believes that garden chemicals should not be considered in isolation when tackling pests, diseases and weeds. Other approaches, involving cultivation practices, cultivar selection and encouraging or introducing natural enemies, should be considered as alternatives wherever possible before the use of chemical pesticides.
3) The RHS recommends that when a pesticide is required, gardeners should:
i) use an appropriate pesticide for the task.
ii) read and follow all the manufacturer’s instructions.
iii) store pesticides under secure and safe conditions.
iv) dispose of unwanted or out-dated pesticides by consulting the local authority’s waste disposal department.
4) The RHS, through its advisory service, offers advice on the identification of pests, diseases and weeds, and their control. It will also advise when treatment is not required, thus saving the unnecessary use of chemicals.
