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.
Pastora Herbicide, can be used to kill witch grass but we recommend contacting your state extension or Department of Agriculture before use, to be certain Pastora is registered in your state.
Prowl H2O Herbicide is not currently labeled to prevent it from coming back once killed.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."
Unfortunately Prowl H2O Herbicide is not labeled for squash.
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.
