Apparatus for spraying of liquids for herbicidal and insecticidal application and the like has a supporting frame for being carried by a vehicle. An upright support is carried by the frame including an upright post and includes a hydraulic cylinder for providing selective vertical telescoping movement of the post. A hydraulic cylinder provides rotation of the post, for rotating a boom carried by the post. A hydraulic cylinder also provides selective pivoting of the supporting boom section relative to the post for vertical movement. The boom has a supporting boom section, a mid-boom section and a reconfigurable boom end element which may be either an articulating tip boom section or a strip spray attachment of “wishbone”configuration. A hydraulic motor provides selective telescoping movement of the mid-boom section relative to the supporting boom sections. The supporting boom section, mid-boom section and boom end element all include spray nozzles.
