Maltsters have provided a Q&A sheet on the use of Glyphosate to help alleviate concerns for malting barley.
During the growing season, various agrochemical sprays may be used to ensure a high quality, food safe crop. After harvest, malting barley may be stored for more than a year before use. Spoilage by insect or mite infestation or by mould growth are hazards which need to be controlled to minimise risk. As well as being unhygienic, insects can damage the embryo of the grain and can facilitate mould growth which is itself undesirable. A limited number of protection products are authorised for use on stored grain, to be used as part of the management strategy to protect the grain quality and safety.
Member companies of the Maltsters’ Association of Great Britain regularly monitor their barleys for residual protection products resulting from good agricultural and storage practices. These exercises have consistently demonstrated that all residues are well below any legal limits, with the majority of samples containing no detectable residues.
The following charts show results for residues of pre harvest insecticides & field fungicides in UK malting barleys from 2019 crop tested at intake and again at Pre Steep.
