- •
Sown wildflower strips strongly reduced cereal leaf beetle numbers in nearby crops.
- •
This resulted in a 40% reduction of pest-induced crop damage near wildflower strips.
- •
Moreover, crop yield was increased by 10% in fields next to wildflower strips.
- •
Broadleaved cover, flower density and diversity were positive predictors of yield.
