In the Netherlands demands for drift control, without loosing coverage and penetration into dense crops, are among the highest in Europe. A range of sprayer ability to fulfil these demands has been investigated in a demo/test in Oudkarspel in Noord Holland.
In this test HARDI TWIN showed superior results compared to the other techniques (conventional sprayer, sprayer with Airtec nozzles and a sprayer mounted with the Swedish släpduk principle).
The HARDI TWIN sprayer was mounted with air injection nozzles of the same type as HARDI MINIDRIFT.
During the test, water sensitive paper was used both in the horizontal and in the vertical direction in the crop.
