Product Information
Meridian 25WG Insecticide
Meridian 25 WG provides control over a broad-spectrum of grubs and insects in turf. Meridan effectively controls soil insects, especially white grubs for an extended period and with different soil conditions and soil types. It is an effective insecticide when applied as directed to the soil, plant foliage and turf grass. This water dispersible granule may be used on residential lawns, golf courses, interiorscapes and ornamentals. 
Meridian 25 WG will control soil pests like white grubs (larvae of Japanese Beetle, Billbugs, European Chafer, Northern Masked Chafer, Southern Mask Chafer, Green June Beetle, Asiatic garden beetles, and Oriental Beetle. It controls foliar pests such as Whiteflies, Leafhoppers, Adelgids, Mealybugs, Aphids and other insects. It suppresses mole crickets and chinch bugs.
How Meridian 25 WG Works
This neonicotinoid class of insecticide (thiamethoxam) works by both ingestion and contact. Thiamethoxam affects the nicotinic acetylcholine receptors in the insect. It also binds to the soil particles; the roots uptake the insecticide, and it moves into the stems and foliage. It works quickly with a rapid uptake. Insect pests that are feeding on the treated plant will stop feeding and die.
Meridian may also be applied as a foliar application of landscape plants. It is quickly absorbed and is rain-fast upon drying. It continues to be absorbed in the following days, forming a supply of thiamethoxam in the foliage that gives residual control of piercing-sucking and leaf chewing insects. Surface residues will be active for 1-2 days before breaking down and is safe for beneficial insects.

Application Window
Meridian acts as a preventative and curative insecticide with the flexibility of applied treatment (about 3.5 months). Meridian 25 WG is a preventative measure against white grubs within 45 days of adult flight for the targeted species. Sometimes, grubs may be present at application time. Meridian is also effective as a curative treatment of the 1st and 2nd instars.
