🌱 Meso 4 SC Select – Professional-Grade Weed Control for Lawns & Turf

Meso 4 SC Select is a powerful pre- and post-emergent herbicide formulated with 40% mesotrione to deliver professional-level weed control in residential and commercial turf. It provides both contact and residual control, helping prevent new weeds while eliminating existing ones.

This product is trusted by turf professionals for renovations, overseeding, and maintenance programs and is safe for use on many cool-season and warm-season grasses when applied according to label directions.

Meso 4 SC Select works by stopping chlorophyll production in weeds, causing them to turn white and die within 2–3 weeks after application.

⚠️ Temporary whitening of turf may occur. This is normal and will fade as grass recovers.
