A spray assembly includes a support element by which the spray assembly is attached to a vehicle, a first load carrying arm selectively extendable from the support element, and a first nozzle carrying arm attached to the first load carrying arm and having at least two sections connected at a first joint. At least one of the two sections is selectively extendable from the first load carrying arm. A crop sprayer including a vehicle and an attached spray assembly is also disclosed. A method of deploying a spray boom system is disclosed, wherein a support element of the spray boom system is attached to a vehicle. The method includes selectively extending a first load carrying arm from the support element and selectively extending at least one of two sections of a first nozzle carrying arm from the first load carrying arm.

1. A crop sprayer vehicle comprising a sprayer assembly attached to the vehicle, the sprayer assembly comprising: a support element by which the sprayer assembly is attached to the vehicle;first and second load carrying arms on opposing sides of the vehicle, each load carrying arm having a proximal end mounted on the support element and selectively extendable from the support element between a stowed configuration in which the load carrying arm is generally aligned adjacent the vehicle and a spraying configuration in which the load carrying arm extends outward from the vehicle such that the load carrying arm is generally perpendicular to a direction of travel; andfirst and second nozzle carrying arms attached to the first and second load carrying arms respectively, each nozzle carrying arm attached to a distal end of its load carrying arm, wherein each nozzle carrying arm has at least two sections connected at a first joint such that a first of the at least two sections extends from the first joint toward a first end of the nozzle arm and a second of the at least two sections extends from the first joint toward a second end of the nozzle arm such that nozzle carrying arm is attached to the distal end of the load carrying arm intermediate the first end and the second end of the nozzle arm, and wherein when the load carrying arm is in the spraying configuration, the first section is selectively extendable such that the first end extends further away from the vehicle than the distal end of the load carrying arm, and the second section is selectively extendable such that the second end extends closer toward the vehicle than the distal end of the load carrying arm. 2. The crop sprayer of claim 1 wherein the support element is attached to a chassis of the vehicle. 3. The crop sprayer of claim 1 wherein the first nozzle carrying arm is attached to the first load carrying arm proximate the first joint. 4. The crop sprayer of claim 1 wherein the first load carrying arm is extendable from a left side of the vehicle and wherein the second load carrying arm is extendable from a right side of the vehicle. 5. The crop sprayer of claim 1 further comprising a second joint positioned proximate a longitudinal mid-point of the first load carrying arm. 6. The crop sprayer of claim 5 further comprising a bend at the second joint. 7. The crop sprayer of claim 1 further comprising a second joint positioned proximate a longitudinal mid-point of at least one of the two sections. 8. The crop sprayer of claim 1 further comprising a hydraulic cylinder attached to the support element and attached to the first load carrying arm, wherein changing a length of the hydraulic cylinder causes the first load carrying arm to extend from the support element. 9. The crop sprayer of claim 1 wherein extension of the first load carrying arm from the support element comprises movement of the first load carrying arm in a pivoting motion, the motion being in a plane substantially parallel to a ground surface under the vehicle. 10. The crop sprayer of claim 1 wherein extension of at least one of the two sections of the nozzle arm from the load carrying arm comprises movement of the at least one of the two sections in a pivoting motion, the motion being in a plane substantially parallel to a ground surface under the vehicle. 11. The crop sprayer of claim 1 wherein the first nozzle carrying arm comprises an elongated frame, wherein a portion of the frame is movable for alignment substantially parallel to a ground surface under the vehicle. 12. The crop sprayer of claim 11 wherein a distance between the portion and the ground surface is adjustable. 13. The crop sprayer of claim 1 wherein the support element is attached proximate a front of the vehicle or wherein the support element is attached proximate a rear of the vehicle. 14. A sprayer assembly comprising: a support element configured for attachment to a vehicle;a first load carrying arm selectively extendable from the support element; anda first nozzle carrying arm attached to a distal end of the first load carrying arm and having at least two sections connected at a first joint such that a first of the at least two sections extends from the first joint toward a first end of the nozzle arm and a second of the at least two sections extends from the first joint toward a second end of the nozzle arm such that nozzle carrying arm is attached to the distal end of the load carrying arm intermediate the first end and the second end of the nozzle arm, wherein the first section is selectively extendable such that the first end extends further away from the vehicle than the distal end of the load carrying arm, and the second section is selectively extendable such that the second end extends closer toward the vehicle than the distal end of the first load carrying arm. 15. The spray assembly of claim 14 wherein the first nozzle carrying arm is attached to the first load carrying arm proximate the first joint. 16. The spray assembly of claim 14 further comprising a second joint positioned proximate a longitudinal mid-point of the first load carrying arm. 17. A method of deploying a spray boom system, wherein a support element of the spray boom system is attached to a vehicle, the method comprising: selectively extending a first load carrying arm from the support element;selectively extending at least one of two sections of a first nozzle carrying arm from the first load carrying arm; andchanging a degree of bend in the first load carrying arm to thereby change a distance between at least one of the two sections of the first nozzle carrying arm and the vehicle. 18. The method of claim 17 further comprising: selectively extending a second load carrying arm from the support element; andselectively extending at least one of two sections of a second nozzle carrying arm from the second load carrying arm;wherein the first load carrying arm is extended from a left side of the vehicle and wherein the second load carrying arm is extended from a right side of the vehicle. 19. The method of claim 17 further comprising changing a distance between the first nozzle carrying arm and a ground surface under the vehicle.
