In experimental treatments of vineyards against downy mildew, a Pintagram pneumatic sprayer on a Bell G helicopter using 10–15 lit./ha. was compared with pressure spraying with ground equipment (200 lit./ha.) or from a helicopter (50 lit./ha.). The efficacy of the Pintagram was slightly less than that of the ground sprayer but was comparable to the conventionally equipped helicopter and allowed the profitability of treatments to be raised by some 30%.
