Yes, 2,4-D Amine Herbicide and Prowl H20 can be tank mixed and applied together. Follow the most restrictive instructions on the product labels and we also recommend doing a compatibility test before mixing larger quantities. A compatibility test will check for changes in color, odor, and consistency. If any of these chemical changes are observed then a tank mixture would not be recommended.

As long as you keep horses out of the area while you treat and until the Prowl H2O Herbicide application has had time to completely dry (typically 4-6 hours after you water in the application) it is safe to return and resume normal activity
The rates for Prowl H2O Herbicide will depend on what crops you’re treating in. Please see the product label beginning on page 13 for a breakdown of specific crops and their rates.
How long to plant after application of Prowl H2O Herbicide depends on the type of application you are doing and the type of crops you are planting. Complete instructions on page 7 of the product label list other timing depending on the application method. Page 13 will give timing for replanting based on the crops planted.
Prowl H2O Herbicide and Prodiamine 65 WDG will have a shelf life of 3-5 years if stored properly in a temperature stable environment (between 45 and 75 degrees) and out of direct sunlight.
Prowl H2O Herbicide lists on the SDS the water solubility as dispersible.
Once Prowl H2O Herbicide is applied and watered in the barrier to prevent is there and starts to work to prevent weeds that have not germinated from emerging, timing is always key for best results. The general rule for spring is to apply your pre-emergent herbicide treatment after the ground has thawed from the winter but before the temperature of your soil reaches 55 degrees, as that is when crabgrass begins to germinate. Other weeds will germinate when the soil temperature is between 55 and 65 degrees. You can use a soil thermometer to determine the temperature of your lawn/area. You will want to measure the temperature of the soil a few inches below ground.
The rates for Prowl H2O Herbicide will depend on what crops you’re treating in. Please see the product label beginning on page 13 for a breakdown of specific crops and their rates.
Yes, Prowl H2O Herbicide is labeled to be used on buffalograss & is labeled to control sandburs
Yes, Prowl H2O Herbicide can be applied to pasture land.
Pre-emergents such as Prowl are generally applied twice a year in spring and fall depending on the grass type. 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.
Per products 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.The rates for Prowl H2O Herbicidewill depend on what crops you’re treating in. Please see the product label beginning on page 13 for a breakdown of specific crops and their rates. However, it is not labeled for mare's tail.
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.

Prowl H2O Herbicide is applied at 2.1 to 6.3 quarts per acre per application depending on the grower's weed control program, level of weed infestation, and desired use strategy, but not more than a total of 6.3 quarts/A per year in citrus and nut trees, and nonbearing date palm and nonbearing fig trees.
Please view the full product label for more information.
Prowl H2O Herbicide is labeled to use on alfalfa, artichoke, asparagus, brassica head and stem vegetables, carrot, citrus fruit trees, bearing and nonbearing, corn (field, field seed, fresh sweet, popcorn, popcorn seed), cotton, date palm trees, nonbearing, edible beans, fallow, fig trees, nonbearing, fruiting vegetables, garlic, grain sorghum, grape, bearing and nonbearing vineyards, hops, leek, lentil and peas, melons, mint, nut trees, bearing and nonbearing, olive trees, bearing and nonbearing, onions and shallots (dry bulb, green), peanut, perennial grasses grown for seed, pome fruit trees, bearing and nonbearing, pomegranate, potato, rice, safflower, soybean, stone fruit trees, bearing and nonbearing, strawberry, sugarcane, sunflower, tobacco, triticale and wheat.
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.
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."
