    Q
    How soon after planting fescue grass seed can you put down Prowl H2O Herbicide?
    A

    Prowl does state on the label to only apply to established (grass with 6 or more tillers per plant) perennial cool season forage grass like fescue.  You will need to wait until it is fully established before applying.  Per product label when you can reseed areas depends on what area you are in and if applied in the spring or fall, as well as the amount of rain/irrigation the area received in the year.
    Per page 13 of products label for annual or perennial grass crops or mixtures you would have to wait anywhere from 10-20 months.

    Q
    How much prowl H2O per acre of watermelons?
    A
    Prowl H2O Herbicide may be applied sequentially in melon production. Initially apply up to 2.1 pints per acre of Prowl H2O as a shielded application between rows with 6 inches on either side of row middles (before melon transplanting or before a seeded crop has emerged) or between rows covered with plastic mulch (before holes are punched in plastic for melon planting). Make a second shielded application at up to 2.1 pints per acre of Prowl H2O between rows with a minimum of 6 inches on either side of stem or vines or between plastic mulch before melon vine running. The interval between the sequential Prowl H2O applications must be at least 21 days. Avoid spray contact with melon foliage or running vines because crop injury will occur.

    Q
    Can Prowl H2O Herbicide be applied to kill weeds over established clover crop/pasture without injuring the clover?
    A

    Prowl H2O Herbicide is not labeled for use on clovers or other legumes except for alfalfa. Broadleaf weeds would have to be handpulled or directly spot treated with a non selective like Roundup QuickPro. Grassy weeds can be controlled with Grass Out Max without injuring clover. 

    Please view the Grass Out Max product label for more information.

    Q
    Using Prowl H2O on hay fields for horses.
    Our hay field, (orchard grass, timothy a little clover & alfalfa) is over-run with meadow and green or yellow foxtail. and a lot of milkweed. We also have black locust tree starts & some poison ivy. How will Prowl H2O do on these unwanted invaders?
    A

    Prowl H2O Herbicide will provide pre-emergent control for green and yellow foxtail but will not work on milkweed or poison ivy. Unfortunately, there are no other pre-emergents for use in hay fields labeled for these weeds. Check out Weedmaster for use as a post-emergent, it can be used in some hay fields except in alfalfa or clover. We also recommend contacting your local extension office or department of agriculture for other recommendations we may not be aware of.

    Q
    I have some Prowl 3-4D and can spray this on grape vines in a pasture and if so what would the mixture rate?
    Is this simulare to 2-4D?
    A

    We do not carry a product called Prowl 3-4D, and we are not familiar with a product by this name. However, we do carry Prowl H2O. The active ingredient is Pendimethalin. This is not similar to 2, 4D as this product is a pre emergent. 2, 4D is an active ingredient in post emergent herbicides. The product label states that Prowl H2O Herbicide can be applied to grapes, bearing and nonbearing vineyards.
     
    "Use Method, Rate, and Timing 
    Prowl H2O may be applied in a single application or sequentially with an interval of 30 days or more. Uniformly apply Prowl H2O in grape vineyards at 2.1 to 6.3 quarts per acre depending on the grower’s weed control program, level of weed infestation, and desired use strategy. 
    Prowl H2O may be applied anytime after fall harvest, during winter dormancy, in spring, and in season before harvest. 
    Ground Application (Bearing) Prowl H2O may be applied surface incorporated or (surface) preemergence. Apply Prowl H2O broadcast or banded using ground equipment before weed germination. Apply spray directly to the ground beneath grape vines and/or in areas between rows. DO NOT apply over the top of grape vines with leaves, buds, or fruit. Contact with leaves, shoots, or buds by the spray mixture may cause injury or result in illegal pesticide residues on fruit. 
    Ground Application (Nonbearing) Prowl H2O may be applied for preplant incorporated, preplant surface, surface incorporated, or preemergence weed control in nonbearing vineyards. Prowl H2O may be used before or after transplanting. 
    Preplant Surface. Before transplanting, uniformly apply with ground equipment. Avoid root contact with treated soil when placing transplants into the hole or injury may occur. 
    Preplant Incorporated. Uniformly apply Prowl H2O before transplanting but before weeds germinate. Incorporate Prowl H2O to a depth of 1 to 2 inches. Application and incorporation must be made before transplanting to avoid mechanical injury to the crop. Avoid root contact with treated soil when placing transplants into the hole or injury may occur. 
     
    Preemergence. Application may be in a band or broadcast. 
    Nonbearing Grape Newly Transplanted and One-year-old Grapevines: - DO NOT allow spray to contact buds or leaves or leaf distortion may occur. - DO NOT apply to newly transplanted vines until ground has settled and no cracks are present.
    Chemigation Application Prowl H2O may be applied through sprinkler irrigation and drip irrigation systems. Follow all directions, special instructions, and restrictions about chemigation in the Application Instructions section of this label. DO NOT apply Prowl H2O-treated irrigation water over the top of grape vines with leaves, buds, or fruit. Contact with leaves, shoots, or buds by spray mixture may cause injury or result in illegal pesticide residues on fruit. 
    Flood, Flooded Basin, and Gravity Flow Irrigation Systems Prowl H2O may be applied in flood, flooded basin, and gravity flow irrigation systems. Follow all directions, special instructions, and restrictions about flood, flooded basin, and gravity flow irrigation systems in the Application Instructions section of this label. 
    Crop-specific Restrictions - DO NOT apply over the top of grape vines with leaves, buds, or fruit. - DO NOT apply by air. - DO NOT apply more than 6.3 quarts per acre per year. - Preharvest Interval (PHI) - 21 days - Prowl H2O-treated vineyards (post-harvest) may be grazed by livestock."

  • Asked by Tom from Prospect, Ky
    05/07/2023
    Q
    I applied Prowl H20 about 48 days prior to planting a food plot mixture of sunflowers & cow peas, and spring oats, after 3 weeks I have little to ant plant growth. could the application od prowl have prevented my seeds from growing. I used a no till drill to plant.
    A

    It is possible that an application of too much Prowl H2O Herbicide could prevent the germination of seeds that are usually tolerant of the herbicide. While there are uses for sunflower and cowpea on the full product label, wild oats are listed as a target weed. So it is possible for the Prowl to prevent germination of the oats. For the cowpeas and other edible beans, there is a table with incorporation rates according to your soil type on page 22 of the product label.
