    Q
    It's June 13 so can I still use this product on my barberry bushes?
    A
    There is no specific time to use this product on barberry bushes. If you are speaking temperature wise, if it is very hot, Atrimmec Plant Growth Regulator should be used in the early morning or late evenings. If treated plants are subject to rainfall or overhead irrigation within 6 hours after spraying, effectiveness may be reduced.

    Q
    Which surfactant should I choose when using Atrimnmec Plant Growth Regulator?
    This is a quote from the label tips for bark banding: "when bark banding or soil drenching a 100% organosilicone surfactant is necessary." Can you tell me which surfactant I should purchase that fits this specification?
    A

    When using Atrimmec Plant Growth Regulator you would want to use a surfactant like Prime Source Duo Stick. This is going to be a proprietary blend of methylated seed oil and organosilicone surfactants.

    Q
    How much Atrimmec Plant Growth Regulator would I need to treat two trees?
    I have a 15 yr. old cherry tree, and a 10 yr. old Sweet Bay Magnolia. Also, does this work on boxberry and crimson barberry? Are the directions on the label?
    A

    You will use 1-3 ounces of Atrimmec Plant Growth Regulator per gallon of water for most foliar sprays for growth control. Small trees up to 16 feet require 1-5 gallons per tree, and larger trees 20-30 feet require 10-15 gallons of solution per tree. Thorough coverage provides best results. Both cherry laurel and barberry are listed with rates on the product label. We are not sure this product would be effective on the magnolia or boxberry since those species have not been tested or shown to be affected per the product label. Be sure to read the entire label before using this product.

  • Asked by Ben from Leland, Nc
    12/29/2016
    Q
    Can Atrimmec Plant Growth Regulator be used on loropetalum (fringe flower)?
    A

    Atrimmec Plant Growth Regulator is not labeled specifically for Loropetalum, fringe flower, witchhazel (the family of this plant), or evergreens, so we are not sure whether it would be effective or tolerated on this plant. Pruning seems to be recommended and most effective for keeping this plant to desirable sizes. Different cultivars will require slightly different care, too. You can read more about Loropetalum in this article from the Clemson Extension. If you are going to try this on your loropetalum, then we would recommend treating a limited number of plants before treating all of them.

    A

    Atrimmec Plant Growth Regulator (PGR) is not labeled for use on turfgrass, only on the listed plants/ornamentals.  Podium (Generic Primo MAXX) or Pac Low would be better options for turf.

    Q
    Is your Atrazine 4% the same strength as Atrazine 4% at Lowes?
    I need broadleaf weed killer for St. Augustine and Centipede grass. Is Atrazine the best thing for these broadleaf weeds in Florida? also, is All Atrazine 4 % the same?
    A
    We can only speak to the products that we carry as we are unfamiliar with products that are sold at Lowes. The Atrazine products that we carry are a 4% concentration and work very well to control the weeds listed on the product label.

    Q
    Can you spray the sides of the shrubs, such as privets, with Atrimmec Plant Growth Regulator (PGR)?
    Will it hurt to spray the sides of the shrubs, or are you only supposed to spray the tops of the shrubs?
    A

    Atrimmec Plant Growth Regulator (PGR) is labeled to be sprayed on shrubs and ornamental plants, such as privets. Per the product label: “This product is a systemic plant growth regulator applied as a foliar spray. It is absorbed by the leaves and translocated to the shoot tips. Growth retardant effect is limited to sprayed branches. This product is absorbed through the leaves and translocated to the shoot tips. Pinching effect is limited to sprayed branches.” So any branches that you spray will be affected by the product.

    Q
    Can overspray of Atrimmec Plant Growth Regulator (PGR) kill other plants it is not labeled for?
    Wind has picked up during application and carried some onto other plants
    A

    Atrimmec Plant Growth Regulator (PGR) doesn’t actually kill anything but it could effect the growth of other products if they are inadvertantly contacted during application.  Only time will tell if they are affected though.

  • Asked by John from Fayetteville, Arkansas
    02/07/2020
    Q
    Can you apply Atrimmec Plant Growth Regulator without trimming in early spring?
    I trim my properties neatly in the fall and winter. I would like to know if you can apply early spring without trimming and before bushes start to grow vigorously. Or if it is necessary to first cut or trim and then apply within 36 hours. Early- mid summer is very busy time of year and I would like to avoid trimming then. Last year I applied after trimming in July and it lasted until fall/winter with light growth.
    A

    According to the product label for Atrimmec PGR:

    For a more formal appearance: Trim the shrub or groundcover to shape, leaving at least two pairs of extended leaves on each shoot to absorb the spray. Apply this product within three days.

    For a more natural appearance: Either trim only the long, wild shoots and immediately apply this product spray, or trim shrub or groundcover to shape, allow the new shoots to grow at least two inches, and then apply this product spray.

    Trimming after the application of Attrimec may interfere with the action of the product.
