Creating Industry-Leading Innovations

  • Novel equipment & formulations
  • Applicator-centric design
  • Rigorously field tested

Plant healthcare is unlike anything else in the Green Industry and requires specialized tools to perform the work properly. Since the early days of injecting trees in the 1970’s, Rainbow has been at the forefront of innovative equipment design specific to the needs of proper plant care.

We not only design the equipment that is best for the trees and plants, we also design the equipment that is the best for the applicator. We know that it is somebody’s job to use these tools each day, so we consider everything from ergonomics to how they ride in the truck to how they are cleaned at the end of the day. We field test our innovations in real-world environments so you know you have the performance you can count on.
