Meso (Commonly known as Tenacity™) herbicide can be used for pre and post-emergence control of more than 46 broadleaf weed and grass species. Its active ingredient, mesotrione, is based on a naturally occurring compound produced by the bottlebrush plant (Callistemon citrinus) that inhibits photosynthesis in susceptible plant species. It is absorbed by plants through the roots, shoots and leaves and distributed throughout the plant by both xylem and phloem translocation.

Meso is one of the few herbicides that controls weeds in cool season grasses during the seeding process and provides pre-emergence and some post-emergence control of many weeds.

Weeds controlled: Common Chickweed, Common Dandelion, Creeping Bentgrass, Crabgrass - Large, Smooth and Southern, Ground Ivy, Henbit, Clover, Lawn Burweed, Mouse-ear Chickweed, Oxalis, Speedwell – Persian, Purslane, Shepherd’s Purse, Sowthistle, and Wild Violet. Meso can also suppress Annual Poa.

Pre-emergent at seeding - When sowing 100% Perennial Rye lawns or 100% Tall Fescue lawn, Meso can be used as a pre-emergent at the time of seeding. This must be done before the seed begins to germinate. The product will not stop the new grass seed from germinating, but will prevent weeds from establishing. The application rate is 3.6 – 5.6ml in 3-5L of water for every 100m2. When applied as a pre-emergent follow up with 3mm of irrigation to get the product on the soil. 

This product can also be tank mixed with Etho for ultimate pre-emergent control in Rye and Tall Fescue lawns. If introducing top dressing apply Meso/Etho over the top of the new layer of material. 

Note: For post-emergent applications it's best to keep Meso and any Etho applications separate, particularly on Tall Fescue lawns.

It's not recommended to use Meso as a pre-emergent in Fine Fescue lawns, this is due to a reduction in density of Fine Fescue seedlings. If using a blend of turf species (which is not recommended due to the difficultly controlling grass weeds) as long as the blend is less than 20% Fine Fescue by weight Meso can be used as a pre-emergent.

Post-emergent application – Meso can be applied to Perennial Rye, Tall Fescue or Fine Fescue lawns at the rate of 3.6 – 5.6ml per 100m2 in 4-5L of water. Lawns need to have been mowed two to three times and be at least four weeks post-germination before Meso is used.

Application – To prevent overlapping during application, it’s a good idea use a lawn spray dye  in your spray tank. 

Keep pets and children off any treated areas until dry or ideally 24 hours.
