Impact of adhesive adjuvants addition into seed treatments on the flowability of cereal crop seeds

Flow behavior of bulk material is influenced by surface material. The application of different seed treatment slurries indicate a change of boundary friction between the grains as a result of contact. A comparison between adjuvant added and single treated cereal seed was conducted in the present study to evaluate the impact on flowability. Related to the chemical components of the used adjuvants different impacts were detected. The use of plant oil based adjuvants Kantor® and Inteco® reduced the value of released energy compared to single use of seed treatments EfA® and Rubin®TT in crop seeds wheat, barley, rye, oat and triticale at 80% of treatments. Contrary to this, the addition of a polysiloxane based adjuvant MaximalFlow® increased the value of released energy representing flowability in 70% of treatments compared to single use of preparation
