  • Meridian 25WG is a broad-spectrum insecticide that is effective when applied at label rates to turf grass, plant foliage and soil. Meridian 25WG contains 4 ounces of active ingredient per pound of formulated product. The active ingredient in Meridian, Thiamethoxam, is a powerful new-generation neonicotinoid, formulated to provide higher water solubility for faster results, along with significant practical benefits in use.

    Meridian 25WG is active against many sucking and chewing insect pests by contact and ingestion. Meridian 25WG is relatively short-lived on the surface of plant foliage, readily absorbed into plant tissues, and rain fast once it has dried. The rapid translaminar absorption and distribution within leaves provides excellent residual control of foliar feeding insects. In the soil, the active ingredient in Meridian 25WG will control soil pests upon contact or ingestion and is also readily taken up by plant roots.

    Meridian has been shown to be highly effective in controlling Ants (Fire Ants), Beetle, Bugs, Thrips, Whitefly, and Grass Hoppers. The active ingredient moves upwards in the plant to the site of pest infestation. Through feeding on the plant, pests are exposed to the active ingredient in Meridian 25WG. The active ingredient moves upwards in the plant to the site of pest infestation.
