Weed Killers

Selective products target specific plant types (e.g., broadleaf weeds) and are appropriate for lawns and flower beds where you want to keep desirable plants; non-selective (total) herbicides kill most vegetation and are best for clearing driveways, gravel, or preparing a planting area

Common active ingredients include glyphosate (non-selective systemic), 2,4-D and dicamba (selective for broadleaf weeds), and pre-emergents like pendimethalin that prevent seed germination; choose based on target weeds, whether you need contact vs systemic action, and crop/lawn safety

Weed killers in this category range from budget options under $50 to higher-priced specialty or bulk formulations; price varies with formulation type (ready-to-use vs concentrate), container size, and brand

Always read and follow the product label for protective equipment, wind and weather limits, buffer zones near desirable plants, and re-entry or harvest intervals; store concentrates securely away from children and pets and dispose of containers per local regulations

Replanting and re-entry intervals depend on the product and formulation; many contact herbicides may allow safe access once spray residues dry, while systemic or pre-emergent products often list specific wait times on the label—follow the stated intervals for each product

Concentrates typically cost less per treated area and allow adjustable dilution for different jobs, but require correct measuring and mixing; ready-to-use sprays are more convenient for small areas or one-time use

Use systemic herbicides that are absorbed and translocated to roots, follow label directions for repeat applications if needed, and combine chemical treatment with mechanical removal for very persistent species
