Weedmaster Herbicide

Weedmaster Herbicide, manufactured by Nufarm, has been the go-to choice for farmers and ranchers seeking dependable weed control in various agricultural settings. This selective, post-emergent herbicide is engineered to deliver robust, long-lasting control over a broad spectrum of annual, biennial, and perennial broadleaf weeds.

Powered by two powerful active ingredients, Weedmaster Herbicide simplifies application, ensuring better penetration into the plant root zone while providing adequate curative.

Weedmaster Herbicide's strength is its capacity for pre-emergence control with residual activity. This means it can thwart weed germination and continue suppressing their growth, maintaining a weed-free environment.

Tools Needed

This product can be applied using various methods, including ground application with handheld, mechanical, or motorized spray equipment and chemigation spraying, and can be used with compatible sprinkler irrigation systems. Additionally, overhead application is an option where it's applicable and suitable.

How to Use

• Step 1: Determine how much Weedmaster Herbicide to use by measuring the square footage of the treatment area. Measure the length and width of the treatment area in feet, then multiply them together (length X width = square footage). For annual weed application, you will use between 8 to 64 ounces per 5 to 40 gallons of water per acre. Apply 16 to 72 ounces of product per 5 to 40 gallons of water for perennial and biennial weeds. Use the higher spray volume when treating dense or tall vegetation. For small or spot applications, use 1 oz. of product per gallon of water per 1,000 sq. ft. Refer to the label for specific application rates, as this will vary.
• Step 2: In a large container, add half of the required amount of water and then the appropriate amount of Weedmaster Herbicide. Fill the container the rest of the way with the remaining half of the water. Mix well and then pour into the sprayer tank.
• Step 3: Apply Weedmaster Herbicide over the treatment area. Plant only labeled crops within 29 days following application. Refer to the label for specific crop planting intervals, which will vary.

Where to Use

Weedmaster Herbicide is for use on conservation reserve program land, fallow systems (between crop applications), general farmstead, sorghum, grass (hay or silage), pastures, rangeland, sugarcane, wheat, corn (preplant and preemergence), soybeans (preplant), and cotton (preplant). It is also for control of brush and broadleaf weeds on rights-of-way, forest brush, industrial sites, non-irrigation ditch banks, fence rows, and other non-crop areas.

When to Use

This product offers optimal results if applied when weeds are actively growing but before they canopy.

Safety Information

Weedmaster Herbicide 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.

Do not allow people or pets to enter treated areas until 48 hours have passed after application. 

Special Considerations

When using Weedmaster Herbicide, combinations should be used only in recommended areas on the same broadleaf weed species found on both labels. For application methods and other use specifications, use the most restricted limitations from both products' labels.
