The Bichel Committee. 1999. Report from the main committee. Danish Environmental Protection Agency. Conclusions and recommendations of the Committee: 8.7.1 Total phase-out.Diarsipkan 2014-01-19 di Wayback Machine. "A total abolition of pesticide use would result in an average drop in farming yields of between 10% and 25%, at the farm level; the smallest losses would occur in cattle farming. On farms that have a large proportion of special crops, such as potatoes, sugar beet and seed grass, the production losses in terms of quantity would be closer to 50%. These crops would probably be ousted by other crops."
