ABSTRACT
The results that follow the use of a herbicide depend largely on how well or how poorly it is applied, and this, in turn, depends on the operator and his equipment. Equipment is designed to apply herbicides: wet, in sprays or mists, dry, in dusts or granules, and in readily vaporized form for fumigation. Hand sprayers are suitable for treating small patches of inaccessible areas and fence rows, spot spraying, and for situations where the spray is to be applied close to susceptible plants. Boomless sprayers — nozzle-cluster type — are well adapted for spraying roadsides and ditchbanks, under utility lines, and along fence rows. Boom sprayers are adapted for either large areas where complete coverage is necessary or turf areas adjacent to a road where the entire application can be made from a tractor or truck-mounted boom. Mist blowers are power-driven machines that disperse highly concentrated sprays in finely atomized form at low volumes per acre.
