Julia Helfert, colleagues Juergen Niederstrasser, Ute Appeltauer-Brandl, and Iryna Smetanska of the University of Applies Sciences Weihenstephan-Triesdorf in Germany, and Headwall Director EMEA Christian Felsheim presented a poster paper, Weed Detection in Dried Parsley using Hyperspectral Imaging, at the 2nd Online International Conference on Agriculture and Horticulture, November 30, 2021.
Changing climate conditions in Western Europe bring about contamination of slow-growing commodities such as parsley (Petroselinum crispum) with fast-growing invasive plants.
Creeping thistle (Cirsium arvense) also contaminates parsley due to its sharp thorns. Groundsel (Senecio vulgaris) is one invasive weed in the cultivation of parsley, containing pyrrolizidine alkaloids (PA). New legal requirements demand strong maximum permissible values for PA.
Hyperspectral Imaging Techniques (HSI) have become powerful tools in determining food quality. HSI should offer the technical opportunity to differentiate between the product and its undesired weeds.
