Insecticide Usage on Oilseed Rape Continued to Increase After Introduction of Neonicotinoid Seed Treatments
Since the early 1990s, pesticide usage on oil seed rape (OSR) has increased significantly in terms of the number of times treated, weight per hectare applied and number of active substances. Although Budge et al (2015) established that neonicotinoid seed coatings enabled farmers to reduce the number of insecticide sprays on OSR, this is not evident from the survey data after 2000 when neonicotinoid seed treatments were introduced.
