Abstract: An applicator is illustrated for introducing a flow of chemical adjacent the roots of a plant without supplying chemical to adjacent plant material utilizing a tubular guide (A) which acts as a cover for a needle (D) which is carried by an inner tubular support (B) which carries a dispensing tube for connection to a source of pressurized chemical (F). The dispensing tube is connected through the handle (E) and a compression spring (G) is provided to urge the tubular guide (A) downwardly for acting as a guard for the needle.
