Roundup ProMAX Herbicide, manufactured by Monsanto, is a post-emergent systemic herbicide that delivers non-selective control of a wide range of annual weeds, perennial weeds, woody brush, and trees.
This product comes in a water-soluble formulation and has a built-in surfactant.
When RoundUp ProMAX Herbicide is applied to a weed, it is absorbed by the plant, preventing it from attaining photosynthesis and gathering nutrients to sustain itself. Roundup is transported throughout the weed, killing the entire plant down to the root.
Tools Needed
This product can be applied through various spray equipment, like a backpack sprayer or a spraying rig. For the average home application, a handheld pump sprayer should do.
How to Use
- Step 1: Determine how Roundup ProMax Herbicide to use by measuring the square footage of the treatment area. To find the square footage, measure the length and width of the treatment area in feet, then multiply them together (length x width = square footage). Rates for RoundUp Promax vary depending on the concentration ratio from 0.4% concentration (0.5 oz. per gallon per 1,000 sq. ft.) to a 7% concentration (9 oz. per gallon per 1,000 sq. ft.). When using RoundUp Promax, typically, it takes 2 oz. of concentrate per gallon of water for most general applications. Brush and Vines require 5 to 9 oz. of solution per gallon of water.
- Step 2: Fill the spray tank with the required amount of water and then the appropriate amount of Roundup ProMax. Fill with the remaining half of the water, close the lid, and agitate the sprayer to ensure the product is well-mixed.
- Step 3: Apply the solution to the desired area via a fan spray setting for uniform coverage. Spray generously but not to the point of runoff. Plants should die within 24 hours. If not, reapply after 7 to 10 days for particularly stubborn weeds.
Where to Use
Use RoundUp ProMax is ideal to be used in non-crop areas such as airports, apartment complexes, commercial sites, ditch banks, driveways, dry ditches, dry canals, fencerows, golf courses, greenhouses, industrial sites, landscape areas, lumber yards, manufacturing sites, municipal sites, natural areas, office complexes, ornamentals, parks, parking areas, pastures, petroleum tank farms and pumping installations, public areas, railroads, rangeland, recreation areas, residential areas, rights-of-way, roadsides, schools, shade houses, sports complexes, storage areas, substations, turfgrass areas, utility sites, warehouse areas, and wildlife management areas.
When to Use
Applications should be done when weeds are young and actively growing. If weeds are under stress, such as during a drought or cool temperatures, you may need to apply a higher dosage to get the weeds to die out.
Safety Information
Roundup ProMax is safe to use around children and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when mixing and applying this product.
Keep pets and children away from the treated area until the product has dried.
Special Considerations
Apply Roundup ProMax to foliage in a coarse spray setting. Spray to wet and make it uniform. Using a spray pattern indicator to keep track of your spraying and avoid over-spraying with this product would be wise.
