Abstract: A spray shield assembly adapted to be moved over row crops to temporarily enclose the crops when liquids are sprayed onto them or the ground around them, which assembly includes a liquid distribution system for distributing liquid to outlet nozzles, and a polymeric shield defining a channel opening through one side and front and rear ends of the shield for receiving the crops. The shield has a converging leading portion for directing portions of plants into the channel, and a semi cylindrical portion in which the nozzles are mounted, with two of the nozzles in one of an array of openings in opposite sides of the shield, which arrays of openings allow adjusting the location of the nozzles to accommodate the portion of the plants desired to be sprayed.
