A fluid delivery assembly is operably coupled with a reciprocating saw having a saw blade to deliver a treatment fluid to a cut portion of vegetation as the vegetation is cut. A syringe contains the treatment fluid and a fluid delivery tube has a reservoir end in fluid communication with the syringe and a delivery end adjacent the cut portion of the vegetation. A carrier is contains a portion of the fluid delivery assembly and a harness attached to the carrier has at least one strap for an operator to carry the carrier during operation of the reciprocating saw. A stepper motor is operably coupled to a PCB for storing operating parameters and for executing the operating parameters to induce advancing movement of a plunger relative to the syringe. The operating parameters are provided to the PCB by an external computing device and the PCB and stepper motor receive electrical power through an electrical power and logic cable from a power supply of the reciprocating saw. The fluid delivery tube is provided with a check valve at the reservoir end and the delivery end to retain the treatment fluid within the fluid delivery tube.
