Poast Herbicide

Poast Herbicide, manufactured by BASF, is a broad-spectrum post-emergent herbicide that eliminates annual and perennial grass weeds in specific crops, nonagricultural land, and other terrains.

This emulsifiable concentrate quickly enters weeds like crabgrass and foxtail through the leaves and moves throughout the unwanted plant. With its active ingredient, sethoxydim 18.0%, this product will stop the plant's ability to divide cells, leading to a stunt in weed growth and eventual death.

Poast Herbicide provides fast and dependable control of grassy weeds within 3 weeks of treatment and allows a flexible harvest rate for listed crops. After one hour of application, this product becomes rainfast.

Tools Needed

You will need a knapsack sprayer or spray rig. This product may be mixed with crop oil concentrate (COC) or methylated/modified seed oil (MSO).

How to Use

• Step 1: Determine how much Poast Herbicide 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, divide the square footage by one acre (square footage / 43,560 sq. ft. = acres). For spot treatments, use 1.9 fl. oz. of Poast Herbicide with 1.3 fl. oz. COC or MSO in 1 gallon of water. To treat weeds in clover, apply 2.5 pints of product in 20 gallons of water per acre. For conservation reserve lands, use 2.5 pints of product in 20 gallons of water per acre. For specific application rates, refer to the product label.
• Step 2: Fill your sprayer with half the water, add a measured amount of Poast Herbicide, and pour in the remaining half of the water. Close the sprayer and agitate until well-mixed. For spray rigs, spray to mix the product solution.
• Step 3: Spray the mixed Poast Herbicide solution at least 4 feet above the ground or crop canopy until wet, but not to the point of runoff. A minimum of 14 days is required between sequential applications of this product.

When to Use

Apply when weeds are young and actively growing, but spray when rainfall is not expected an hour after application. Treat crops as stated on the product label.

Do not apply this product to grass weeds or crops under stress because of lack of moisture, hail damage, flooding, herbicide injury, mechanical injury, or widely fluctuating temperatures.
