Introduction of Släpduk in the Netherlands

In collaboration between the farmers union, extension service and agricultural research the Swedish Släpduk spray system was identified as a potential drift reducing measure. It was however doubted whether all crop protection applications could be done in arable crops as the plates that maintain nozzle height are in touch with the crop. Experiments were started over two years to evaluate the Släpduk used in Dutch arable crops potatoes, sugar beet and cereals. All crop protection applications were done with a Släpduk system next to a conventional sprayer. No differences were found in biological efficacy in either one of the crops and crop damage was limited. Also drift measurements were performed to minimize obligatory crop-free buffer zones when the Släpduk sprayer is going to be used in the different crops. Up to 99% drift reduction could be obtained with the Släpduk system compared to a standard field sprayer equipped with XR11004 nozzles. Farmers groups noted the perspective of the system and an introduction programme is started. Aspects as virus distribution through the fields by plate contact and touch of sensitive vegetable crops were identified as subject of attention and further research.
