Concerning a second product or more: the other product(s) are generally "injected" via a Raven Injection system. In these secenarios extra smaller tank(s) are mounted on the sprayer to contain the injected product(s) such as RoundUp.

The Injection system injects the proper amount of chemical into the flow stream where it is mixed via a mixer prior to being distributed to the spray boom. Since the injection system is aware of ground speed, boom width and desired rate it can run at the proper speed to dispense the correct amount of product.

It is very common in this area to see sprayers with injection systems. There are various combinations using one or more pumps and a variety of tanks.
