Abstract: An applicator for the topical application of liquid treatment fluids to plants provides for remote actuation of opposed grasping or pressure plates, thereby allowing even and symmetrical pressure to be applied to the plant as the treatment liquid is administered. The result precludes uneven pressure to the plant and possible subsequent bending of the plant and contact with another adjacent plant, thereby precluding secondary application of any treatment liquid to the adjacent plant and possible injury to that adjacent plant. The application operation is easily conducted remotely, by actuating a trigger to clamp the plant in the opposed members. One of the members includes a porous sponge or pad, which pad communicates with a treatment liquid container via a tube or conduit in order to provide a positive coating of plant treatment liquid to the plant interposed between the two plates adjacent the pad. The treatment pad is shielded from inadvertent contact with adjacent plants by the two plates.
