Advances in developing a new test method to assess spray drift potential from air blast sprayers
Spanish Journal of Agricultural Research, 2017 Drift is one of the most important issues to consider for realising sustainable pesticide sprays. This study proposes and tests an alternative methodology for quantifying the drift potential (DP) of air blast sprayers, trying to avoid the difficulties ...
