Early pesticides and biocontrol
The first pesticides were relatively simple organic compounds including sulphur, copper and even nicotine. The deliberate and strategic use of biological control however dates back to the third century when Chinese farmers managed green tree ants to help in the battle against stink bugs.
The advent of synthetic pesticides (starting with DDT and its relatives) saw a decline in biocontrol practice that has lasted for decades.
Are pesticides useful?
Many would argue that they have been essential tools to modern agriculture and it is difficult to refute this. We believe that pesticides themselves are not the problem – it is the way we manage these compounds that has created massive problems on a global scale including effect on non-target organisms, resistance development and contamination of waterways and the food we eat. The inappropriate use of certain pesticides can also lead to pest flare due to adverse impact on ‘good bugs’.
While many may argue that pesticides are needed in modern agriculture their use in backyards, gardens and landscapes must surely be questioned.
What can you do to reduce dependence on pesticides?
- Create an environment that is favourable for beneficial insects and mites. Generally biodiversity is a good thing and plants that offer protection, pollen and nectar feature well here.
- Understand your pest problems and seek solutions other than a toxic poison that comes in a spray bottle.
- Choose to grow plants that are well suited to your environment and soil type. Avoid plants that suffer from a high degree of pest pressure that may require regular pesticide applications.
- If appropriate, introduce beneficial insects and mites to help your cause and to supplement your natural population of good bugs.
