Actual losses comprise the crop losses sustained despite the cropprotection practices employed. In 2001-03, more than 50 % of actual maize production was only available due to manual, mechanical and chemical cropprotection. This flexibility is especially useful in farming systems that do not rely on cropprotection chemicals and high fertilizer inputs. These examples are from corpora and from sources on the web.
