Systematic Monitoring of Residues
In order to assure sufficient high-quality harvests, use of some pesticides is required in agriculture. Quantities and times of application are subject to strict legal stipulations, with the objective of having as little residues as possible on harvested goods and on food prepared with same. Maximum quantities are set out clearly. Hops have been monitored especially carefully for residues of plant protectants for a long time. Hopsteiner has developed a systematic residue analysis for testing hop plants. The results of the last campaign are presented below.
