    How we choose the best weed killers

    Every year, our Labs evaluate hundreds of chemical formulas for efficacy and completeness of label directions, safety warnings based on ingredients and how easy each product is to use.

    To find the best weed killers, we looked at offerings from popular brands we know and trust, as well as products that are highly rated and reviewed. Because there are chemicals in weed killers that could be of concern to humans and the environment, we teamed up with sustainability expert, Dr. Michael Brown, Ph.D., of Brown and Wilmanns Environmental, to review the ingredients in each and eliminate products that could potentially be harmful from our list.

    Some of the harmful chemicals we looked for were possible carcinogens, endocrine disruptors, neurotoxins, respiratory toxins or chemicals that may cause skin sensitization. (Some examples of chemicals we avoided are glyphosate and 3,6-dichloro-2-methoxybenzoic acid). To assess these potential hazards, safety data sheets were evaluated for each ingredient; our experts also performed additional research for anything that might not be listed on the safety data sheets.

    What to consider when shopping for the best weed killer

    ✔️ Check what types of weeds and plants the weed killer is intended to be used on. Some weed killers will kill all types of vegetation that you may not want killed including lawns, flowers and vegetables.

    ✔️ Ready to use vs. diluted. Ready to use formulas are convenient as they are ready to go, but concentrated formulas will be able to cover a lot of ground and last a long time since you’ll only use a small amount of product.

    ✔️ Check the labels for safety warnings and wear protective gear such as goggles or gloves as recommended by the manufacturer. Although a product may be labeled “all-natural” or “organic” it does not necessarily mean it’s safe around kids and pets.

    How do weed killers work?

    Emergent weed killers destroy weeds at specific growth stages. Pre-emergent weed killers help prevent weeds from popping up by targeting the sprouting weed underground before it reaches the soil surface. Post-emergent weed killers focus on getting rid of the weed once it has emerged from the soil.

    • Selectivity refers to particular weeds the weed killer will target. Selective weed killers will destroy specific vegetation and not others, so check product labels to ensure it’s targeting the correct weeds without harming other plants. Non-selective weed killers will get rid of weeds and any other greenery around that it’s applied on, so you’ll want to take care around plants you want to keep alive.

    • Translocated weed killers absorb into the plant’s system causing it to slowly die from within. These types of herbicides take longer to produce results, from several days to weeks, but often destroy the entire plant making them a good choice for weeds with deep roots. This is different from contact weed killers, which only kill the part of the plant where it is applied and results can be seen from several minutes to a few days.

    • Persistence refers to how long the weed killer stays in the soil once it’s applied. Some weed killers deteriorate after several days where others last a few months to possibly a year. If you will be planting in the area where the product is being applied in the near future consider a weed killer that doesn’t last as long, however, if that is not an issue a longer-lasting product may be beneficial so it won’t need to be reapplied often.
