An analysis comparing conventional and air‐assisted sprayers indicates that even over relatively small areas air‐assisted spraying offers advantages of both economics and efficacy. An analysis of Danish meteorological data from 1989 to 1991 indicates that, without including any savings on plant protection products, air‐assisted sprayers proved most economic at total sprayed areas of over 600 ha, which with a typical Danish rotation equals a farm area of approx. 160 ha. Danish users of air‐assisted sprayers claim reduction in their use of plant protection products of 25‐30%. If more modest reductions of only 20 or 10% are considered, the break‐even occurs at total sprayed areas of only 300 or 200 ha, equalling typical farms of 77 or 52 ha, respectively.
