    Q
    Will CoreTect control emerald ash borer?
    A
    CoreTect is labeled for flat headed borers and emerald ash borers are a species of flat headed borers. According to the product label: You will need to use 3 tablets per inch of trunk diameter. For treatment of in-ground ornamentals – For best results on established ornamentals, CoreTect Tree and Shrub Tablets Insecticide should be placed as close to the fine absorptive roots as possible. For most deciduous trees and shrubs, an adequate number of these absorptive roots are located with 6-24” of the trunk, depending on tree size. Apply CoreTect Tree and Shrub Tablets Insecticide 2-5” below the soil surface, next to the plant (ca. within 3-5” of newly planted trees or shrubs, or within 6-24” of well-established ornamentals). Ensure that the tablets are completely covered with soil after application.
    For bushy coniferous trees and shrubs, numerous absorptive roots may be located near the drip-line. To apply CoreTect Tree and Shrub Tablets Insecticide post-plant to plants with a definite drip-line, place tablets 2-5” below the soil surface, evenly spaced around the tree and along the drip-line. Ensure that the tablets are completely covered with soil after application.

    07/06/2010
    Q
    How many tablets of CoreTect do I need to use for a 7' tall ficus hedge for whitefly prevention?
    A continuous hedge runs along the entire side of my 100" property, and it is about 2-3 feet wide. My neighbor's front hedge shows a serious white fly problem, and I want to use this as a preventative measure. How many tablets should I apply and at what spacing in the ground?
    A
    You will need to take a look under the hedge and treat each root system individually instead of treating the hedge as one plant. According to the CoreTect product label, you will need 3 tables per foot of shrub height, so for a 7 ft plants you will need 21 tablets for each plant. Release of active ingredient is dependent on presence of adequate soil moisture. For best results, irrigate the plant after treatment, and ensure that the plant receives regular irrigation for at least 2-3 months after treatment

  • Asked by Marco from Altadena, Ca

    Q
    How often do I need to use CoreTect ?
    In order to prevent future infestation of Aphids in my Deodar cedar, how often should I apply CoreTect ? How do I find out if my tree has drip line feeder roots or near the main trunk feeder roots ?
    A

    While Coretect is not designed as a “preventative” treatment, if you follow the label for amount of tablets needed for the particular plant, the Coretect can stay in the plants system and treat for up to 2 years. The exact time will vary so keeping a watchful eye on the plant for any pest activity is going to help determine the longevity of the product in the plant/area. We recommend contacting a local master gardener or arborist to either come look at the plant, or to see if they know off hand the root area of the given plant.

  • Asked by Luli
    02/18/2011
    Q
    How can I apply CoreTect to my property when the usage rate seems to exceed the yearly limit?
    We were looking to purchase CoreTect for our ficus to prevent a white fly infestation, and we have some questions.
    A
    You are correct that you cannot use more than 450 tablets of CoreTect on one acre of property per year. In fact, on your smaller parcel of land you cannot use more than 90 tablets per year. You have a unique situation in that you have so many ficus on such a small piece of property. Every systemic product does have about the same usage limits that you have found on the Coretect. You could of course treat your most susceptible ficus with the systemic Coretect and use a product with a different active ingredient such as Talstar P on the less susceptible ficus as a foliar spray. It might be a good idea to check with a company that specializes in ficus/whitefly to see what they would recommend in your situation. (Most companies will offer a free estimate and will provide you with a plan of action)

    Q
    Is CoreTect Tree & Shrub Tablets the right product for Hybrid-T Roses?
    A
    Coretect is labeled for rose bushes but they do not list different species of roses. We recommend that you contact your local cooperative extension office and speak to the master gardener on staff to seek advice on Hybrid-T Roses. Most botanical gardens also offer free advice to the public and may be a great resource if you have one in your community.

    Q
    Is CoreTect effective against bagworms in mature Eastern Red Cedar trees?
    A
    CoreTect tablets is not specifically labeled for bagworms. We recommend using Talstar P for bagworm control. Timing is key when spraying for bagworms. Apply when larvae begin to hatch and spray larvae directly. Applications when larvae are young will be most effective. You can check with your local Cooperative Extension Office to see when bagworms become active in your region.

    Q
    What does "regular irrigation" mean on the CoreTect Tree & Shrub Tablets Insecticide label?
    We just planted the tablets on 2 maple trees. we have been watering daily, but does regular irrigation mean to just be sure the soil stays moist or drenched? It is fall here in Pennsylvania and cool now.
    A

    Regular irrigation would be just has you have been doing after using the CoreTect Tree & Shrub Tablets Insecticide.  The goal is to keep the soil wet for 2-3 months so the product gets pushed down the roots and is readily absorbed by the roots.

    Can CoreTect Tree & Shrub Tablets Insecticide be used indoors on a large houseplant?
    A

    CoreTect Tree & Shrub Tablets Insecticide is really designed for larger planting areas such as outside landscapes or large interiorscape plantings, so we would not recommend this product for smaller houseplants.  A great product for systemic insecticide control on smaller containerized plants is Bonide Systemic Houseplant Insect Control.
