Abstract
A cutting line for a rotating-line trimmer that simultaneously applies herbicide as vegetation is cut. The herbicidal cutting line comprises a flexible cutting-line core (13) herbicidal coating (15) that covers all or part of the line core and a thin protective shield (17) covering all or part of the herbicidal coating. As vegetation is cut, protective shield (17) ruptures exposing herbicidal coating (15) to vegetation. The cutting line is used with existing line trimmers in applications in which vegetation regrowth is objectionable.
Claims28
A cutting line, comprising an elongate filament suitable for use in rotating line trimmers, said filament being coated or impregnated with herbicide which is releasable by the trimming action.
A system for applying a chemical to vegetation, comprising:
- a supply of a filament, which includes a biologically-active chemical;
- and a trimmer mechanism coupled to the supply of filament, the trimmer mechanism rotating a working end of the filament at a rate sufficient to trim vegetation on contact therewith, wherein such trimming action applies the chemical to the trimmed vegetation.
A system for applying a herbicide to vegetation, comprising:
- a supply of a polymeric filament, which includes an integrated herbicide;
- and a trimmer mechanism coupled to the filament, the trimmer mechanism rotating a working end of the filament at a rate sufficient to trim vegetation on contact therewith, wherein such trimming action applies the herbicide to the trimmed vegetation.
A method for applying a chemical to vegetation, comprising:
- Supplying a filament, which includes a biologically-active chemical;
- coupling a trimmer mechanism to the supplied filament, and operating the trimmer mechanism to rotate a working end of the filament at a rate sufficient to trim vegetation on contact therewith, wherein such trimming action applies the chemical to the trimmed vegetation.
A method for applying a herbicide to vegetation, comprising:
- supplying a polymeric filament, which includes an integrated herbicide;
- coupling a trimmer mechanism to the filament;
- and operating the trimmer mechanism to rotate a working end of the filament at a rate sufficient to trim vegetation on contact threrwith, wherein such trimming action applies the herbicide to the trimmed vegetation.
