1. A method for treating a plant in a field as a farming machine traverses the field, the farming machine comprising a plurality of treatment mechanisms configured for treating plants in the field, the method comprising:
responsive to treating a previously identified plant in the field, measuring an initial pressure of a fluidic system controlling treatment mechanisms of the farming machine;
identifying the plant in an accessed image of the field based on pixels in the accessed image representing a feature of the plant;
selecting one or more treatment mechanisms to treat the plant, the one or more treatment mechanisms configured to operate at a treatment pressure;
actuating one or more pressure regulation systems of the fluidic system to modify the initial pressure of the fluidic system to the treatment pressure, wherein:
the pressure regulator comprises a front pressure regulator and a back pressure regulator that control flow of treatment fluid to the one or more treatment mechanisms, and
the front pressure regulator and the back pressure regulator are both actuated to modify the initial pressure to the treatment pressure; and
treating the plant using the plant with a treatment at the treatment pressure using the one or more treatment mechanisms.
