Weed Killers That Contain Triclopyr

Weeds are one of the most common problems faced by gardeners and homeowners. They appear in unwanted places–woods, parks, agricultural areas and private lawns–growing quickly and interfering with the growth and propagation of desirable plants. Not all herbicides are created equal. Some herbicides kill indiscriminately, while others target certain plants.

Triclopyr, registered for use in 1979, targets broadleaf weeds and woody brush without killing grasses and conifers. Herbicides containing triclopyr are particularly useful over large areas such as golf courses and roadsides, where targeting individual weeds would be inefficient.

Effectiveness
Triclopyr weed killers eliminate unwanted weeds and plants. Their efficiency is unaffected by rain or watering. Ortho weed killers eliminate thistle, English daisies, spurges, chickenweed, plantain, clovers, dandelions, henbits, wild onions and numerous other weeds.

Application
Triclopyr weed killers are sold in concentrated form (they require additional dilution) and in ready-to-spray bottles. They are most effective when applied in temperatures between 45 degrees Fahrenheit and 90 degrees Fahrenheit. Appropriate safety precautions are required during application. It is recommended you wear gloves, goggles and a face protection.
