By adding FirstRate herbicide to your weed control program, you will be giving soybeans your best shot.
FirstRate can be tank-mixed with other herbicides and used in non-GMO or glyphoste tolerant soybeans to improve control of broadleaf weeds.
FirstRate offers superior control of both giant ragweed and Canada fleabane when compared to other soil-applied programs or post-emergent programs
Pre-emergence (8.5 g/ac)
Pre-emergence (17 g/ac)
|Post-emergence (8.5 g/ac)
1Note: Group 2 resistant biotypes are known to exist and these populations will not be controlled
Preplant | Pre-emergent
For control of giant ragweed (preemergence and cotyledon to 4 leaf stage), heavy infestations of lambs‑quarters, common ragweed, velvetleaf and cocklebur, apply FirstRate herbicide at a rate of 41.7 grams of product per hectare (one water soluble packet treats 0.4 hectares).
For control of giant ragweed (cotyledon to 6 leaf stage) and above labeled weeds apply FirstRate herbicide at a rate of 20.8 g/ha (one water soluble packet treats 0.8 hectares) plus 0.25% v/v Agral® 90 plus 2.5% v/v liquid fertilizer (28-0-0 or 32-0-0).
For control of giant ragweed and Canada fleabane (up to the 20 leaf stage) and other labeled weeds as well as suppression of horsenettle.
Apply FirstRate herbicide at a rate of 20.8 g/ha (one water soluble packet treats 0.8 ha) plus 0.25% v/v Agral® 90 plus 2.5% v/v liquid fertilizer (28-0-0 or 32-0-0).
FirstRate Herbicide may be applied any time prior to the flowering stage of soybeans. Application prior to full emergence of the first trifoliate leaf may cause temporary yellowing of soybeans. This effect is transient and has no effect on soybean yields. Application timing restrictions of tank-mix partners should be followed. When applied in a tank-mix combination, follow applicable use instructions, including rates, precautions and restrictions of each product used in the tank mixture.
When tank mixing with other herbicides, follow the crop rotation on the label of each product used.
Crop Rotational Interval (Months)
A field bioassay should be conducted before planting other crops not listed above. A successful field bioassay means growing to maturity test strips of the crop(s) intended for production the following year.
Water soluble packaging: 10 x 17 g water soluble packets per package
Bottle: 4 x 340 g/case
FirstRate herbicide is a water dispersible granule formulation. Thorough mixing is required. Vigorous, continuous agitation during mixing, filling and throughout application is required. Sparger pipe agitators generally provide the most effective agitation in spray tanks. To prevent foaming in the spray tank avoid stirring or splashing air into the spray mixture. To prevent foaming during filling keep end of fill pipe below the surface of the liquid in the spray tank. The addition of an anti-foaming agent such as Halt® may also reduce foaming.
The following method is recommended:
Rainfast: 2 hours
Do not harvest soybean plants for forage or hay. Do not harvest soybeans for 65 days after application.
Caution: Do not graze the treated crops or cut for hay; sufficient data are not available to support this.
