Merit Systemic Insecticide Granules

White Grubs    Merit Insecticides    Lawn Pests    Japanese Beetle

How to Order Merit Granules, Grub Control

Active Ingredient...0.50% Imidacloprid

Merit Granules General Information, Ordering

Merit 0.5 G is a granular product that contains more Imidacloprid than standard store brand granules.  Merit systemic granules give long term control of lawn pests such as white grubs.  The secret to control of white grubs (the immature larvae of Japanese Beetles, May/ June Beetles, Chafers) is to use a systemic product at a specific time of the year.  This timing of insecticide application is crucial for effective killing grubs that feed on grass.  If granules are spread on lawn at the incorrect time, your product will probably be wasted and the targeted pest will continue to feed on your turf grass.

Application to Turfgrass    Application to Ornamentals    Grub Control 

Merit Systemic Granules contain .5% of the active ingredient Imidacloprid.
Most store brands of grub control that use Imidacloprid contain only 0.2% active ingredients.
Use professional strength Merit for more economical, professional results.

There are many pests controlled by Merit although the most popular use is in white grub control.  The systemic action gives the long term control needed for a good grub kill but timing of insecticide application is just as important as using the best product for the job.

Application for White Grubs    Pests Controlled by Merit Granules

Application for White Grubs

White Grub is a generic term for the larval stage of a group of beetles that include Japanese Beetles and May/ June Beetles Timing of insecticide applications for grubs in lawns is the most important part of the job.  Just as in controlling molecrickets, grub elimination must be timed to target the youngest stage of the grubs that are close to the surface.  While at or near the surface of your lawn, the grubs are easier to kill.  Grubs that are in their early or most immature stages are more vulnerable to your pesticide application than the older grub stages.
Merit Systemic Granule applications made to lawns in July and early August will have the best control.  Contact your local county extension office if you need to know the exact time to apply white grub control products in your area.

Merit Granules help take some of the guess work out of when to apply your pesticide.  This product has a longer residual, which translates into a much larger window of opportunity for you and overall better control of the grubs in your lawn.  For more information on white grubs, their biology and tips for elimination, go to the White Grub Control article.
You will need one bag of Merit Granules per half acre of lawn turf grass to be treated for white grub control.  After broadcasting the granular insecticide, irrigate the area thoroughly.  You will need a deep watering to push the insecticide down to the roots of your plants so that the plant can take up the insecticide.

Application to Turfgrass

Merit 0.5 G Insecticide can be used for the control of soil inhabiting pests of turfgrass, such as Northern & Southern masked chafers, Cyclocephala borealis, C. immaculata, and/ or C. lurida; Asiatic garden beetle, Maladera castanea; European chafer, Rhizotroqus majalis; Green June beetle, Cotinis nitida; May or June beetles, Phyllophaga spp.;  Japanese beetle, Popillia japonica; Oriental beetle, Anomala orientalis; Billbugs, Spherophorus spp.; Annual bluegrass weevil, Hyperodes spp.; Black turfgrass ataenius, Ataenius spretulus; Aphodius spp; and mole crickets, Scapteriscus spp.
Merit 0.5 G Insecticide can also be used for the suppression of cutworms and chinch bugs in turfgrass areas.  Merit 0.5 G Insecticide can be used as directed on turfgrass in sites such as home lawns, business and office complexes, golf courses, airports, cemeteries, parks, playgrounds and athletic fields.  Merit insecticide cannot be used on commercial sod farms.

The active ingredient in Merit 0.5 G Insecticide has sufficient residual activity so that applications can be made preceding the egg laying activity of the target pests.  High levels of control can be achieved when applications are made preceding or during the egg laying period.  The need for an application can be based on historical monitoring of the site, previous records or experiences, current season adult trapping or other methods.  Optimum control will be achieved when applications are made prior to egg hatch of the target pest, followed sufficient irrigation or rainfall to move the active ingredient through the thatch.  Applications should not be made when turfgrass areas area water logged or the soil is saturated with water.  Adequate distribution of the active ingredient cannot be achieved when these conditions exist.  The treated turf must be in such a condition that the rainfall or irrigation will penetrate vertically in the soil profile.  Applications cannot exceed a total of 80 lb. (0.4 lb. of active ingredient) per acre per year.

Application to Ornamentals

Merit 0.5 G Insecticide can be used as a broadcast application on ornamentals in commercial and residential landscapes.  Merit 0.5 G is a systemic product and will be translocated upward within the plant system.  Optimum control will be achieved when applications are followed by sufficient mechanical incorporation, irrigation or rainfall to move the active ingredient into the soil.  Applications should be made prior to anticipated pest infestation to achieve optimum levels of control.
Applications of Merit 0.5 G Insecticide cannot exceed 80 pounds per acre per year.

Systemic Action

A systemic insecticide works from the inside out instead of only on the exterior surfaces of treated plants.  Systemic Merit granules give you advantages over conventional granules or sprays.  Once the lawn (for instance) is treated with Merit, the insecticide is not as exposed to sunlight and rainfall as regular bug sprays.  Systemic insecticides give a longer residual than other insecticides used to treat lawns, which is very important when timing an application to control white grubs in lawns.  For a more thorough look at the topic, go to Systemic Insecticides Information page.
