Vehicular apparatus for spraying herbicides and insecticides has a supporting frame for being carried by a truck or trailer. Upright supports are carried by the frame and trailing boom supports extend rearwardly from the upright supports, which carry structure for selective pivoting of the trailing boom supports relative to the upright supports to permit vertical adjustability of the spray. Lateral booms are supported by the trailing boom supports and connected to them such that the lateral booms can pivot relative to the trailing boom supports and ground. The lateral booms include a supporting base section, a mid-section, and a boom tip section. At least the tip section of the lateral boom includes spray nozzles for selective liquid spraying. A pivotal connector connects and provides forward and backward horizontal pivotal movement of the boom mid-sections relative to the boom base sections. Another pivotal connector connects and provides vertical pivotal movement of the boom tip sections relative to the boom mid-sections. The pivotal connectors provide selective horizontal and vertical lateral boom section positioning as well as approximation by the boom sections of terrain contour to be sprayed.
