The differences between pre-emergent and post-emergent herbicides for weed control

Even the most beautiful lawn can become a haven for weeds. Fortunately, there is a large selection of herbicides available to homeowners. Perseverance, suitable timing, and, most importantly, appropriate treatments when and where needed are all required for weed control. Herbicides are not all created equal, and each has special features that make it effective at different stages of the weed’s growth and development. We’re here to assist you in distinguishing between pre and post-emergent herbicides and in streamlining your weed management efforts.

Pre-Emergent Herbicides

Herbicides that are applied prior to the emergence of weeds are known as pre-emergent herbicides. Pre-emergents, rather than interfering with the growth process, aid in the prevention of germination, which is the process by which weeds develop and sprout from the soil.

Pre-emergents should be applied to the entire turf area to ensure no weeds arise in previously untreated areas. It’s also vital to water pre-emergent herbicides to boost efficiency and ensure that herbicides reach the soil. In the right conditions, with adequate watering, pre-emergents can remain active in the ground for up to 8 weeks. It is recommended that pre-emergents be used with caution on newly seeded turf or turf that is in need of rehabilitation.

Post-Emergent Herbicides

The use of post-emergent weed management treatments can effectively eliminate many different types of weeds, including perennial, annual broadleaf, and even grassy weeds. Post-emergent weed killers, in contrast to pre-emergent weed killers, can be used to spot-treat weeds rather than having to treat the entire turf area.

The timing of post-emergent herbicide applications is essential since these chemicals are most effective when applied to weeds that are just emerging. Weeds that have reached maturity are ugly and may necessitate repeated spraying. Inspection of the turf should be done regularly to ensure that any new weed growth can be treated immediately.
