  • Asked by Luis from Watkinsville, Georgia
    01/27/2021
    Q
    When should I apply Simazine 4L Herbicide in the Winter/Spring to bermuda?
    I applied according to the label 1 qt/acre in October. When should I reapply?
    A

    According to the label, Simazine 4L Herbicide should be applied in late winter before the weeds emerge for control of summer annual weeds listed. So you want to apply when your soil temperatures have stayed at least 55 degrees for 5 days.  

    You may contact your local cooperative extension office to determine the correct timing of the application as this will vary greatly from region to region.

  • Asked by Tim from Hollywood Md
    02/18/2021
    Q
    Why can't Simizine be used north of North Carolina?
    Simazine Precautions: (3) Do not use north of NC. Does this mean you cannot use in MD or PA? The label precautions indicates the product should not be used north of NC for turf grass application. Are we reading this correct? The precaution is buried down in the details.
    A

    That is correct, Simazine 4L Herbicide should not be used north of NC because it is only safe for warm season turf grass.

  • Asked by Karen from New Bern, Nc
    09/01/2024
    Q
    Will Simazine kill bentgrass that is growing in my centipede grass without killing the centipede?
    A

    Simazine 4L is a preemergence herbicide only for preventing weeds emerging from seed when applied before they germinate.  It does not control anything actively growing and is not labeled for bentgrass control. Tenacity Herbicide is our most popular product for eliminating bentgrass from other desirable turfgrasses, but it does typically require multiple applications. Late summer/Fall applications will be more effective than Spring applications. If you are able to spot treat with RoundUp QuikPro, that is another option. It would still be ideal to wait at least 10-14 days after applying the Roundup QuikPro before raking out the dead plants and re-seeding those areas.

    A

    Simazine 4L Herbicide is a pre emergent that works to prevent listed weeds on the product label from germinating.

  • Asked by Steve from Waupaca Wi
    08/07/2022
    Q
    Is Simazine 4L Herbicide safe for soybeans and white pine and red pine seedlings?
    A

    Simazine 4L Herbicide is not labeled to be used on soybeans, so we would not recommend it. The only mention of soybeans on the label is a precaution stating, "In western Minnesota and eastern parts of the Dakotas, Nebraska, and Kansas, do not plant soybeans following corn treated with SIMAZINE 4L if more than 2 qts. of SIMAZINE 4L per acre (or equivalent rate in a band) were applied, as injury may occur."
     
    This product is labeled to be used on Red Pine (Norway Pine) and White Pine, however, it is not labeled specifically to be used on seedlings. Pre emergents stop seeds from germinating, and pre emergents are normally recommended to be used on established plants and grasses as instructed.

    Please be sure to review the product label for more information and complete application instructions.
