The sprayer includes a tool bar to which a plurality of adjustable primary spray hood assemblies are pivotally mounted so as to be vertically movable as well as adjustable in pitch angle from front to rear so that the assemblies will follow the terrain of a field being sprayed. The primary spray hood assemblies include detachable nozzles for supplying chemicals to weeds confined within the hoods of the assemblies. Auxiliary spray nozzles are mounted exteriorly of the hoods for spraying chemicals toward the base of adjacent crop rows. In some embodiments secondary hood assemblies for covering plant rows are provided intermediate the primary spray hood assemblies and are used for spraying chemicals to the foliage of the plants in the crop rows.
