While herbicides act systemically and physiologically — from within, so to speak — misleading the life body's higher organising function in its relation to the physical organisation, the mechanical methods of regulating weed growth act from without. Through weeding, harrowing with the weeder, harrowing, and hoeing, the plants are uprooted; through mowing they are severed from the root stock. These measures do not step outside the lawfulness of becoming and passing away. This applies equally to flame weeding, which catches rapidly germinating and growing weeds before the germinating seed of the cultivated plant has broken through the soil crust and turned green.
