Meridian 0.33 G Insecticide

Broad-spectrum Insecticide

Meridian provides preventive and curative control of grubs, billbugs, and other foliar insect pests. Meridian will quickly control or prevent most pests that damage turf, trees, and shrubs and it fits the operational requirements of a lawn care operator because of a wide application window and relaxed water requirements. Meridian is quickly becoming a cornerstone in helping to keep customers’ lawns and landscapes healthy, green, and pest free.

Unique mode of action - Low rates - Excellent control

Meridian controls a wide variety of sucking and chewing pests at very low rates, both through contact and ingestion activity. Key chemical attributes make Meridian very effective in both foliar and soil applications. In foliar uses, Meridian dries quickly and is taken into the leaf, providing fast insect control. When applied to the soil, Meridian is absorbed and transported to the upper portions of the plant, while still remaining available for sub-surface control. This is due, in part, to its relative solubility, which allows the product to move through organic matter for very effective control of soil insects.

Wider application window with relaxed water requirements

Meridian offers the lawn care operator flexibility by widening the window of application, by providing season-long preventive control on their schedule. Immediate watering by your customers or Mother Nature is not required, as Meridian is effective even if there is no rain or irrigation for up to a week after application.

Broaden your spectrum and your efficacy

Meridian provides comprehensive control of both key foliar pests and soil pests like grubs and fire ants. In fact, you can achieve very effective fire ant control in just four to five days with a mound drench, compared to 60 days with the leading product. Meridian mixes well with other insecticides like Scimitar® CS to target a wider spectrum of foliar pests, including caterpillars, cutworms, and adult beetles.

Curative properties solve customer issues quickly

Meridian is labeled for curative control, and is effective through late second instar white grubs. Meridian insecticide’s outstanding water characteristics allow the product to quickly move into the soil profile. Outstanding uptake properties allow Meridian to travel within the plant more easily and over greater distance than other insecticides, giving you the versatility to also use the product to protect trees and shrubs from insect damage.

Powerful and versatile—yet gentle

While Meridian is highly effective on insects, it’s easy on plants. Studies have shown safety in trials where applications were up to four times the prescribed use rates. There is also versatility in the formulations, with both a 0.33G inert granular product and a 25WG (wettable granule) for spray applications.

For specific information about developmental stages of the target pest and optimal timing of applications, consult with your State Cooperative Extension Service.

Note: For turf with heavy thatch (more than 0.75”), use the higher rates within the specified rate range. Do not exceed 80 pounds of Meridian 0.33G per acre per year. Meridian 0.33G (is not phytotoxic) can be used on all major turfgrass species.

Note: Meridian 0.33G provides suppression of mole crickets on turfgrass. Suppression can mean either erratic control, ranging from good to poor, or a consistent level of control below that generally acceptable for commercial purposes. Refer to additional comments under Use Information section relating to turfgrass applications.

Spreader settings for Meridian 0.33G Insecticide: Spreader settings are influenced by factors such as speed, equipment wear, and condition of spreader. Use the following chart as a guide in establishing accurate calibration of your spreader to properly apply Meridian 0.33G at labeled rates. Carefully calibrate application equipment prior to commercial use of this product.

APPLICATIONS TO ORNAMENTAL PLANTS

Soil-Inhabiting Pests

Application timing for Grubs:

• Apply up to 45 days before the historical peak of adult flight to 2nd instar grub of the species being targeted.
• For optimum control, treat from peak flight to peak egg hatch.
• To control grubs, make the application from egg hatch to second instar (grubs less than half their full size).
• Note: If leaching, wait a minimum of 7 days after application to allow for maximum uptake of Meridian 0.33G by the plant’s root system.
• Apply to the soil before pests are evident in situations where tolerance of insects or damage is low. Allow a minimum of one week for smaller plants and at least 2 weeks for large plants to translocate Meridian 0.33G to feeding sites of the target pest.
• Do not exceed 80 pounds per acre per year when making applications to the soil for ornamentals.

For specific information about developmental stages of the target pest associated damage and action thresholds to properly time applications consult with your State Cooperative Extension Service. Refer to additional comments under Use Information section relating to turfgrass applications.

Above-Ground Pests

Application Timing for Above-Ground Pests:

Preventive: Apply 1 to 4 weeks before pest has historically been observed.

Curative: Allow 1 to 4 weeks for reduction in pest density to occur.

Note: Larger plants require the longer interval.

• Note: If leaching, wait a minimum of 7 days after application to allow for maximum uptake of Meridian 0.33G by the plant’s root system.
• Apply to the soil before pests are evident in situations where tolerance of insects or damage is low. Allow a minimum of one week for smaller plants and at least 2 weeks for large plants to translocate Meridian 0.33G to feeding sites of the target pest.
• Apply to landscape ornamental plants to reduce populations of aphids, whiteflies, and mealybugs, which produce honeydew which serves as a food source for some ant species.
• Do not exceed 80 pounds per acre per year when making applications to the soil for ornamentals.
• Apply the proper rate as a broadcast treatment to the root zone of plants.
• Irrigate after application for optimum control.
