Martin's 2,4-D Amine Selective Weed Killer, manufactured by CSI, is a water-based herbicide designed to eliminate post-emergent weeds and brush from pastures, rangelands, and non-crop areas like lawns and ornamental turf within 21 days.

It is made with the powerful active ingredient Dimethylamine Salt of 2,4-D 47.2%, which removes weeds like dandelion and ground ivy in hard-to-control places due to its selective control measure.

Martin's 2,4-D Amine Selective Weed Killer gives professional and beginning applicators quick control over unwanted vegetation, helping to leave lawns and crops healthy and weed-free.

Tools Needed

You will need to use a handheld pump sprayer or a spray gun mounted on a boat, tractor, or truck. For land applications, you may consider using a spray rig for acreage treatments.

Do not apply this product through any 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.

Also this product may be used for aquatic weed control in ponds, lakes, reservoirs, marshes, bayous, drainage ditches, non-irrigation canals, rivers and streams that are quiescent or slow moving, including programs of the Tennessee Valley Authority.

Do not use on dichondra, herbaceous ground covers, bentgrasses, carpet, buffalo, and injury-sensitive southern grasses such as St. Augustinegrass. Legumes may be damaged or killed.

Do not use it on creeping grasses such as bent grasses except as a spot treatment.

When to Use

For best results, apply Martin's 2,4-D Amine Selective Weed Killer as a water or oil spray during warm weather (but not above 90 degrees Fahrenheit) when young succulent weeds or brush are actively growing. Application under drought conditions often will give poor results. Treat when biennial weeds are in the seedling to rosette stage before flower stalks become apparent. Treat perennial weeds in the bud-to-bloom stage.

As stated on the label, this product may be applied prior to planting to certain crops and in certain stages of crop growth.

Do not spray this product during or immediately following cold, near freezing weather.
