Use of Chemicals

Many clients, especially from European markets, demand that the quality control processes used be documented by the growers; especially a report concerning treatment (spraying) against insects. Such a report includes a list of the materials permitted for use and approved by an official agent, in addition to the timetable of the spraying with details of materials used, the date, concentration, number of days before harvesting and the level of residue of pesticides; the level permitted appears in the Codex Alimentarius published by FAO. This book gives the permitted level MRL (minimum residue limit) according to types of material and species of fruit, vegetables and other foodstuffs.
