A sprayer assembly includes a frame that supports a tank for storing a liquid chemical. A pump moves the liquid chemical from the tank to one or more spray nozzles through a flexible hose supported by a boom arm that is attached to and extends from the frame. To allow for adjustment of the positioning of the spray nozzles, the boom arm has a curved end portion that defines a slot. A fastener can be passed through the slot and into a corresponding opening defined in the frame to attach the boom arm to the frame. As such, the boom arm can be fixed at any orientation between 90�� (vertical position) and 0�� (horizontal position) depending on the application.

What is claimed is: 1. A sprayer assembly, comprising: a frame; a tank supported on said frame and storing a liquid chemical; one or more spray nozzles; and at least one hose for delivering the liquid chemical from the tank to said one or more spray nozzles, each said hose being mounted on and supported by a boom arm attached to and extending from said frame, said boom arm adapted to be fixed at a selected orientation relative to the frame, and said boom arm including: a curved end portion, a slot defined by said curved end portion, and a fastener passing through said slot and into a corresponding opening defined in the frame to attach said boom arm to the frame. 2. The sprayer assembly as recited in claim 1, wherein said boom arm is adapted to be fixed at a selected orientation between a substantially horizontal position relative to the frame and a substantially vertical position relative to the frame. 3. The sprayer assembly as recited in claim 1, wherein an adjustment knob is mounted to an end of said fastener to facilitate the rotation and tightening or loosening of said fastener. 4. The sprayer assembly as recited in claim 1, wherein a first spray nozzle is positioned near one end of the boom arm, and a second spray nozzle is positioned near an opposite end of the boom arm. 5. The sprayer assembly as recited in claim 1, wherein said sprayer assembly includes two boom arms and two hoses, each such hose mounted on and supported by a respective boom arm. 6. The sprayer assembly as recited in claim 5, wherein two spray nozzles are associated with each boom arm. 7. The sprayer assembly as recited in claim 6, wherein a first spray nozzle is positioned near one end of each boom arm, and a second spray nozzle is positioned near an opposite end of each boom arm. 8. The sprayer assembly as recited in claim 1, wherein the liquid chemical is delivered from the tank to said one or more spray nozzles by a pump. 9. A sprayer assembly, comprising: a frame; a tank supported on said frame and storing a liquid chemical; one or more spray nozzles; and at least one hose for delivering the liquid chemical from the tank to said one or more spray nozzles, each said hose being mounted on and supported by a boom arm having a curved end portion defining a slot, said boom arm being attached to the frame at said curved end portion by a fastener passing through said slot and into a corresponding opening defined in the frame, such that said boom arm can be fixed at a selected orientation relative to the frame. 10. The sprayer assembly as recited in claim 9, wherein said boom arm is adapted to be fixed at a selected orientation between a substantially horizontal position relative to the frame and a substantially vertical position relative to the frame. 11. The sprayer assembly as recited in claim 9, wherein an adjustment knob is mounted to an end of said fastener to facilitate the rotation and tightening or loosening of said fastener. 12. The sprayer assembly as recited in claim 9, wherein a first spray nozzle is positioned near one end of the boom arm, and a second spray nozzle is positioned near an opposite end of the boom arm. 13. The sprayer assembly as recited in claim 9, wherein the liquid chemical is delivered from the tank to said one or more spray nozzles by a pump. 14. A sprayer assembly, comprising: a frame; a tank supported on said frame and storing a liquid chemical; at least two boom arms, each said boom arm attached to and extending from said frame, each said boom arm adapted to be fixed at a selected orientation relative to the frame, and said boom arm including: a curved end portion, a slot defined by said curved end portion, and a fastener passing through said slot and into a corresponding opening defined in the frame to attach said boom arm to the frame; one or more spray nozzles associated with each boom arm; and at least two hoses for delivering the liquid chemical from the tank to the spray nozzles associated with each said boom arm, each such hose being mounted on and supported by one of said boom arms. 15. The sprayer assembly as recited in claim 14, wherein each said boom arm is adapted to be fixed at a selected orientation between a substantially horizontal position relative to the frame and a substantially vertical position relative to the frame. 16. The sprayer assembly as recited in claim 14, wherein an adjustment knob is mounted to an end of said fastener to facilitate the rotation and tightening or loosening of said fastener. 17. The sprayer assembly as recited in claim 14, wherein two spray nozzles are associated with each said boom arm. 18. The sprayer assembly as recited in claim 17, wherein a first spray nozzle is positioned near one end of each said boom arm, and a second spray nozzle is positioned near an opposite end of each said boom arm.
