Effects of casings and canopy dividers installed in a spraying unit on rapeseed losses during desiccation

The objective of the present study was to determine rapeseed losses recorded during desiccation with Avans Premium 360 SL, and caused by natural shattering. Shattering seeds were trapped with elastic sticky tapes. Rapeseed losses were determined for a traditional spraying unit and one equipped with canopy dividers, a screen and tractor undercarriage casings. It was found that the additional equipment installed in a spraying unit allowed to reduce rapeseed losses.
