An apparatus and method of applying liquid product to a crop growing in a field. A plurality of drop assemblies are laterally spaced along the boom structure, each of the plurality of drop assemblies include a boom mounting bracket which supports a vertical support member and a spray assembly disposed at a lower end of the vertical support member, the boom mounting bracket having a first pivot axis oriented substantially perpendicular to the boom structure. The drop assemblies are movable from a working position to a transport position. In the transport position the vertical support member is pivoted about the first axis such that the vertical support member is oriented toward the boom structure. In the working position the vertical support is oriented substantially perpendicular to the boom structure.
