ABSTRACT:
Apparatus for treating a field crop with liquid chemical for use with a water irrigation system of the type including a plurality of longitudinally spaced towers, and a mechanism for intermittently moving each of the towers to move the system through the field. The apparatus comprises a first assembly for applying liquid chemical to the field crop canopy and/or ground in a first pattern arranged to extend from one of the towers a majority of the distance toward an adjacent tower in amounts which diminish in a direction away from the one tower, a solenoid valve for communicating liquid chemical under pressure with the first pattern applying assembly only when the one tower is in motion. A second assembly for applying liquid chemical to the field crop canopy and/or ground in a second pattern arranged to extend from the adjacent tower for a majority of the distance toward the one tower in amounts which diminish in a direction away from the adjacent tower, and a solenoid valve for communicating liquid chemical under pressure with the second pattern applying means only when the adjacent tower is in motion.
