  • Asked by Kara from Dacula
    08/21/2017
    Q
    Why are there temperature restrictions on the Hi-Yield 2, 4-D Selective Weed Killer label advising not to apply when it is over 85-90 degrees?
    A

    Hi-Yield 2, 4-D Selective Weed Killer, like most herbicides, generally is most effective when applied to vigorously growing plants at 65 to 85 degrees.  When temperatures are higher than this, weeds can actually start to produce a thicker waxy coating to protect themselves from these hot, dry conditions.  Herbicide movement within the plant will then be reduced because of a slower rate of absorption and metabolism within the weed, causing poor weed control.  Application herbicides early in the morning after the plants have recovered from the heat of the previous day will provide better weed control than afternoon or evening applications.

  • Asked by Marilyn from Milam, Tx
    07/16/2017
    Q
    How do you apply Hi-Yield 2, 4-D Selective Weed Killer to weeds in and around ponds, and how much?
    A

    Per the product label for Hi-Yield 2, 4-D Selective Weed Killer: AQUATIC WEED CONTROL (Surface Application to Floating and Emergent Weeds) Boat Application: Use 1 gallon of this product in 25 gallons of water per acre.

    Uniform coverage is essential. Avoid submerging plants after treatment. Application should be made when leaves are fully developed above water line and plants are actively growing.

    Treatment of aquatic weeds can result in oxygen loss from decomposition of dead weeds. This loss can cause fish suffocation. Therefore, to minimize this hazard, treat 1/3 to 1/2 of the water area in a single operation and wait at least 21 days between treatments. Begin treat- ments along the shore and proceed outwards in bands to allow fish to move into untreated areas.

    The maximum rate per broadcast application is 4.7 gallons per surface acre, limited to applications is 2 per year. Do not make a broadcast application within 21 days of previous broadcast application. Spot treatments are permitted.

    Apply to emergent aquatic weeds in ponds, lakes, reservoirs, marshes, bayous, drainage ditches, non-irrigation canals, rivers, and streams that are quiescent or slow moving

    SPOT TREATMENT IN NON-CROP AREAS: To control broadleaf weeds in small areas with a hand sprayer, use 1 pint (4 fluid ounces) of this product in 3 gallons (3/4 gallon) of water and spray to thoroughly wet all foliage.

    Q
    Can I spray weeds with 2,4-D right after it has rained before the grass is dry?
    A

    You can apply Hi-Yield 2, 4-D Selective Weed Killer to the grass directly after it has rained, however the product may not stick to the grass as well. If you add a surfactant you may get better results.  This product will still work, however it may not work as fast, or you may need to treat again.  For optimum results it is best to apply it once the grass has dried.

    Q
    Will Hi-Yield 2, 4-D Selective Weed Killer kill the centipede grass?
    If not, do you know of a product that will kill centipede grass and not kill the rest of my red fescue lawn?
    A

    Hi-Yield 2, 4-D Selective Weed Killer is a selective, post-emergent herbicide concentrate which controls dozens of broadleaf weeds and other noxious plants susceptible to its active ingredient. It will not kill grasses such as centipede. It is hard to find a product that will kill Centipede in Red Fescue. You could spot treat with Roundup. Another option, would be to contact you Cooperative Extension Office and speak with the Master Gardener.
