Tools Needed

To apply Martin's 2,4-D Amine Selective Weed Killer, you will need to use a handheld pump sprayer or a spray gun mounted on boat, tractor or truck. For land applications, you may want to consider using a spray rig for acreage treatments.

Do not apply this product through any type of irrigation system.

How to Use

• Step 1: Determine how much Martin's 2,4-D Amine Selective Weed Killer to use by measuring the square footage of the treatment area. To do this, measure the length and width of the treatment area in feet then multiply them together (length X width = square footage). For acreage, take the square footage and divide it by one acre (square footage / 43,560 sq. ft. = acres). To treat weeds in the pre-plant stage of corn, use 1 to 2 pints of Martin's 2,4-D Amine Selective Weed Killer in 15 to 30 gallons of water per acre. For pre-emergent weed control in corn (before it emerges), apply 2 pints of product in 15 to 30 gallons of water per acre. For pre-emergent weed control in corn that has just broken ground, use 2 pints of product in 15 to 30 gallons of water per acre. To kill emerged weeds in corn, apply 1/2 to 1 pint of product in 8 to 15 gallons of water per acre. For grass in established pastures and rangelands, use 1 to 4 pints of this product in 1 to 30 gallons of water per acre. For Pasture and Rangeland: Do not apply more than 8 pints of product per acre per year. To control weeds in ornamental turf areas use a rate between 0.75 to 1.16 fl. oz. of product in 1 to 3 gallons of water per 1,000 sq. ft. per application for control of annual broadleaf weeds. Use 1.16 fl. oz. of product in 1 to 3 gallons of water per 1,000 sq. ft per application for control of biennial and perennial broadleaf weeds. For spot treatments in ornamental turf areas, use 1/4 pint of this product in 3 gallons of water. Maximum of 1.16 fl. oz. of product per 1,000 sq. ft. per application for ornamental turf areas. Refer to the label for specific application rates and restrictions.
• Step 2: Mix Martin's 2,4-D Amine Selective Weed Killer only with water. Add about half the water to the mixing tank, then add the measured amount of Martin's 2,4-D Amine Selective Weed Killer with agitation, and finally the rest of the water with continuing agitation.
• Step 3: Spray the Martin's 2,4-D Amine Selective Weed Killer mixture over the top of weeds, but not over the emerged crop. Wet all parts of the unwanted plants thoroughly, including stem and foliage, to the point of runoff. Delay irrigation for 3 days after treatment.

Where to Use

Apply Martin's 2,4-D Amine Selective Weed Killer on labeled broadleaf weeds and brush in corn (field, pop and sweet), sorghum (Milo), soybeans (preplant), small grains (barley, millet, oats, rye, wheat), rice, sugarcane, fallow land, grasses, stone fruits and nut orchards, brush control, pastures, rangelands, forest management and in non-crop areas such as lawns and ornamental turf, drainage ditchbanks, fence rows and rights-of-way.

When to Use
