Herbi-Alarm driveway and terrace spray is a total, non-selective weedkiller for killing weeds, grasses and mosses on paved, non-cultivatable land (paths, driveways, terraces). It can also be used on loose, uncultivated land permanently between rows (all crops) without touching the crop with a protective cap on the sprayer and before sowing or planting ornamental plants and vegetables (all crops).
