Three neonicotinoid insecticides (imidacloprid, thiamethoxam and clothianidin) are currently restricted for use on flowering crops in the EU, in response to evidence of harm to pollinating insects. Evidence continues to accumulate that neonicotinoids pose significant risks to wildlife and the environment, including two major reviews of the evidence (EASAC, 2015 & WIA 2015).
In the UK, OSR is a major crop affected by the restrictions. The purpose of the current report is to review what alternative means of insect pest control are available drawing on research and existing practice.
This report examines the following pest management tools:
- Choice of crop variety
- Crop husbandry, in particular sowing date, establishment methods and crop nutrition
- Use of pest monitoring and thresholds
- Encouraging natural enemies of pests, both by making the crop more hospitable to these species and by providing suitable habitat outside the crop
- Companion planting
- Trap crops
The role of organic farming is also explored.
