Merit 75 WSP - Envelope

As a low cost alternative we recommend Adonis 75 WSP which has the same active ingredient as Merit 75 and treats the same insects for much half the price! 

Merit 75 water soluble packet (WSP) is a liquid insecticide concentrate which can be used at very low rates and applied as a foliar spray, soil broadcast spray, soil injection or soil drench to control grubs, weevils, and other soil and turf inhabiting pests. Soil applications are taken up by plant, ornamental, and tree roots into twigs, stems, and foliage. Merit 75 WSP includes detailed instructions for application to turfgrass, ornamentals, trees, shrubs, flowers, groundcovers, and in and around commercial or residential buildings. Most applications of Merit 75 WSP require the use of a one or two gallon pressurized sprayer. There are 4 x 1.6 oz water soluble packets in each envelope.

    5 of 5 Stars  Merit
    By Bill on September 14, 2010

    Excellent systemic saved my avocado tree from thrips, my ficus hedge from whitefly and my lawn from grub worms. Somewhat effective on the lime tree for leaf miners. Merit can be used on everything around your home, and even as a foundation soak for subterranean termites.

QHow much water do I need to dilute one packet of Merit 75 WSP in for a lawn application?
I want to purchase Merit to treat for grubs, I am having a hard time understanding mixing instructions. It says one packet per 8250 sq.ft but How are we to measure or know how much water to mix etc.. If someone could clear that up it would be great. Thanks

AThe amount of water you use is up to you. The manufacturer recommends that you use an amount of water that is easy for you to handle and calculate. Water simply acts as a carrier and it is important that even distribution of the product is achieved. Thus, more water may be used if the applicator feels runoff will not occur and proper penetration of the root zone is achieved. It is recommended that you use at least 5-10 gallons of water per 1,000 sq ft. After the application is complete you can then go back and irrigate the area to help the product penetrate the root systems.

September 28, 2011Ty from Honolulu, Hi asked:

QI have white fly infestation on my golden duranta hedges in Honolulu where it's hot and humid year round.
I was told Merit was the best systemic insecticide to use. Are there any other similar products that you would recommend?

AMerit works well because it contains the active ingredient imidacloprid which acts as a systemic insecticide, but as you probably know is also quite expensive. We do carry several other products that contain imidacloprid and will work in the same way as Merit, and they are less expensive. Adonis 75 WSP, Adonis 2F, Dominion 2L, Criterion 75 WSP, Fertilome Tree and Shrub Systemic, and Bonide Systemic Granules. Each of these products will work systemically to help treat for whitefly, but the application and usage rate will vary so you should read the product label of the product you are considering and make sure you are comfortable with the application before purchasing. Systemic products can take several weeks to translocate through a plant. During that time the whiteflies can cause a lot of damage so you should use a product such as Talstar P as a foliage spray to help control the infestation while the systemic product is working its way through the plants.

April 1, 2011Jerry asked:

QWhich Merit product is best for systemic treatment of Holly shrubs? What is the proper dosage formula?

AEither Merit WP or the Merit WSP will work for your needs as the only difference between these products is how they are packaged. Merit WP is a 2 oz jar which works well for small jobs and Merit WSP is an envelope that comes with 4 water soluble packets for larger larger jobs. You will need to know the height of each holly shrub and you will use 0.7 to 1.4 level teaspoons per foot of shrub height. The amount of water that is used will vary depending on soil conditions and volumes that are easy for applicators to use. The minimum amount of water that should be used is 1 pint per foot of shrub height but you may use 1 quart -1 gallon of water per foot of height as well. Denser soils such as clay do not accept water as readily, so the lower volume of water is suggested.  Since sandy soils can accept more water, using the higher volume of water is preferred.

February 5, 2013Lisa from Camarillo, Ca asked:

QIs Merit 75 WSP safe to use as a soil drench for Citrus?
Can I use this on Citrus for psyllid control? Should I harvest fruit first? How long will this persist in the plant?

AMerit 75 WSP cannot be used on a citrus tree. The product can persist for about 1 year after the application inside the tree. There is another product called Imidapro 4SC which is labeled for use on citrus trees and it contains the same active ingredient as Merit just in a different formulation.

QSystemic protection for hickory trees from spiral borers
I have three young hickory trees that are losing branch ends to spiral borers. Is there something that I can put on the ground or put below ground at the dripline that would help protect the trees systemically from spiral borers? If not, is there a product that can be injected into or below the bark?

AWe have not been able to find a product that is labeled for the hickory spiral borers. The only information that we could find only recommended breaking off the damaged branches for control of the insect. If you would like to try a systemic insecticide to see if it helps, you could try Merit 75. You can use Merit 75 as a soil drench that would be taken up by the roots of the tree and you can spray the foliage on the tree as well. We would recommend that you contact your local cooperative extension office for further information.

QWill Merit 75 Insecticide get rid of scale and anthracnose?
We have multiple large Ash trees suffering from a severe infestation of scale, and more than likely ash borers. We also have a large Sycamore suffering from Anthracnose. I'm looking at the Merit 75 product for ground treatment around the Ash Trees, and have no idea what to do about the Sycamore?

AMerit 75 WSP would be a great choice for treating scale on the ash trees. We have detailed instructions on how to measure your trees to find out how much you will need to purchase and how to apply properly. Please contact your local Cooperative Extension Office to learn more about the Anthracnose on your Sycamore trees. These offices specialize in the local flora and the diseases and pests associated with it and can be absoluetly invaluable to homeowners.

QCan I use Merit in a Waterboy water machine as a systemic for tropical plants with mealybugs?
Is Merit the most effective product for mealybugs?

AUnfortunately we are not familiar with a Waterboy. Please contact the Waterboy manufacturer to see if wettable powder insecticides can be used in their device. Merit is indeed very effective for mealybugs.

QDoes Merit kill bees
When used as root injection

AMerit 75 WSP is highly toxic to bees even if applied as a root injection. The residue can still be there when the tree or shrub blooms.

May 17, 2010Lou asked:

QI have Tru Green coming to spray Merit on my trees. I have a koi pond. Is Merit harmful to my fish?

A

Yes, Merit like most other insecticides is dangerous for fish. According to the Merit product label:" Do not apply directly to water, to areas where surface water is present or to intertidal areas below the mean high water mark. Do not contaminate water when disposing of equipment washwaters."

May 23, 2012Kimberly from Hickory Corners, Mi asked:

QA lawn care company said my spruce trees have bark beetles, would Merit take care of these and by which method

AMerit is not recommended for most bark beetles because the beetles are under the bark but above the level where the Merit would trans-locate through the tree. Infected trees should be cut down (before the newly hatched beetles fly out of the trees in the spring/summer) and the wood burned or chipped, while other still healthy trees should be sprayed annually to protect them. Because of the natural boring behavior of the beetle they are protected from topically applied insecticides and systemic insecticides (those injected into the tree or applied as a root drench such as Merit) have proven ineffective for pine bark beetle infestations. Healthy trees can be protected before the beetles attack by topically spraying them with a synthetic pyrethroid like Talstar or Permethrin SFR. The trees should be sprayed from the ground to 15 ft up the trunk to prevent future infestations. You should contact your local cooperative extension office to find out the best time to start spraying in your region.

May 25, 2012Fran from Nebraska asked:

QCan I use Merit 75 WSP through my 60 gal pull behind sparyer or will it plug up the screen?

AIt is possible that Merit could clog your sprayer because it is a water soluble powder and the powder could settle causing a clog. We have not had any reports of Merit causing any issues when mixed well. If this is still a concern for you, please consider using a liquid formulation that contains the same active ingredient such as Adonis 2F.

April 20, 2010Gary asked:

QWhat is the best time of year to apply Merit Insecticide?

A

The best time to treat with Merit will depend on the type of insect that you are treating for and the region that you live in. We recommend contacting your local cooperative extension office to ask about insecticide timing for the pests in your region. These offices are an invaluable resource when dealing with pests and most have a master gardener and an entomologist on staff to answer pest insect questions. It is also a great idea to read through the Merit product label as the manufacturer may have provided  information on the best time to treat for a particular insect.
