Zenith 75 WSP Insecticide

Zenith 75 WSP Insecticide delivers superior broad spectrum control of many ornamental and turf insects. Zenith 75 WSP contains the active ingredient, Imidacloprid, which is the same in Merit insecticide. This product will provide season long control with just one easy application. This is also a great preventative because it stops the egg laying action of your targeted pests. Examples of sites to be used on: Turf- golf courses, parks, cemeteries, playgrounds, home lawns, athletic fields, shopping complexies, and sod farms. Can be used on ornamentals on residential, commercial landscapes and interior plantscapes. Zenith 75 WSP comes in an easy to use water soluble packet and can be tank mixed with most liquid fertilizers, fungicides, miticides, and other common insecticides. Has a low use rate which means less hazard to you and non target organisms.


For optimum control of pests, irrigation or rainfall should occur within 24 hours to move the active ingredient through the thatch. Do not apply to turf areas that are waterlogged or if the soil is saturated, because water is needed to penetrate vertically in to the soil.

    5 of 5 stars  Works Great
    By Casey in Riverside Ca on 07/31/2013
    Verified Purchase

    I had a bad root aphid infestation. Couldn't kill them by spraying. I used several products, bifen, malathion, neem oil. I used this as a soil drench and cut the population from 1000's to just a few in one application. A little goes a long way. Only 1 1/2 tsp per 50 gal.

    5 of 5 stars  Zenith 75 for Orchids
    By Ben in La Mesa, CA on 11/19/2013
    Verified Purchase

    This procuct is just emerging as the orchid solution for a systemic insecticide to control scale and mites without spending a forturne. Another orchid enthusiast led me to the product line. With just one applicatiion I believe I can see a vigourous response in my orchid collection. It was by chance I found DoMyOwnPestControl online. What wonderful service! I ordered Zenith 75 on Saturday night and it arrived in the Wednesday mail!

QHow many 1.6 oz packets do I need to soil drench all of my trees?
I have 19 tall trees on my 1/2 acre lot. Each has an average diameter of 35 inches. They are all 6 feet apart.

AYou will need to measure each of the trees diameters to determine how much product you need for a soil drench. Each 1.6 oz (1 packet) ZENITH 75 WSP will treat 24 to 48 inches of cumulative trunk diameter. Please refer to the product label to determine how much you will need for the target pest you are treating. If you have not purchased this product yet please note that you must mix up large batches at a time and will require at least a 25 gallon tank. If have not purchased the Zenith and you do not have a way to make large tank mixes you may want to purchase the Dominion 2L which will allow you to mix very small or large quantities depending on your needs and abilities. You will need .1 to .2 fl oz of Dominion per inch of tree diameter depending on the target pest. Please read the product label for full instructions.
