50 years ago insect pests often had to be collected by hand; today we have intelligent strategies:
- Crop protection
- Deployment of beneficials
- Crossbreeding with resistance genes
Yet farmers are not allowed to deploy crop protection products indiscriminately. They must demonstrate proof of expertise, comply with documentation requirements and use the products as instructed. These requirements are designed not just to protect the environment, farmers and consumers, but also to prevent the development of resistances. Nonetheless, evolution can never be completely outwitted: unwanted weeds adapt to any regularly used method – even mechanical weed-removal methods. A wide range of methods and crop protection products are therefore needed to fight the development of resistances.
