** See re-cropping restrictions for Dicamba with fall applications.
*** 2,4-D tank-mixes in cereals are registered for winter wheat, wheat, barley, and rye; Bromoxynil tank-mixes in cereals
are registered on wheat, oats and barley; bromoxynil/MCPA and MCPA tank-mixes registered on cereals include wheat,
barley oat and rye; Banvel II tank-mixes in wheat, barley, rye oats.

Under drought conditions, deep seeding and/or brief rain showers after seeding may cause injury to emerging seedlings
in sprayer overlaps. NOT for use with Cheminova Glyphosate, Credit 45, Glyphos, Lajj Plus, MPower Glyphosate,
SharpShooter, SharpShooter Plus, Smoke, or Wise Up.

Roundup WeatherMax, R/T 540, Roundup Ultra 2, Roundup Transorb, Startup, only.

Credit 45, Credit Xtreme, Guardsman Glyphosate only.
Rates based on 500 g/L formulations. All formulation concentrations are registered unless indicated otherwise.
Use only amine formulations of MCPA prior to corn, lentil, chickpea and field peas.
Forage grasses include brome grass, crested wheatgrass, intermediate wheat grass, slender wheatgrass, tall
wheatgrass, Russian wildrye, timothy, orchard grass, creeping red fescue, meadow fescue, meadow foxtail, tall fescue,
meadow bromegrass, streambank wheatgrass and reed canarygrass.
Tank mixes in glyphosate tolerant crops:
• Tank mixes or rates listed may not occur on all product labels. Refer to individual product labels for registered tankmixes.
º Canola:
º Lontrel 360 (112 mL per acre)
º Soybean:
º Assure II (101 to 154 mL per acre)
º Pursuit (65 to 85 mL per acre)
º Corn:
º AAtrex (0.63 to 0.84 L per acre)
º 2,4-D single application (108 to 212 g ae per acre)*
º 2,4-D split application (108 g ae per acre followed by 80 to 108 g ae per acre)*
* 2,4-D applications to corn may result in serious injury to some corn hybrids. Consult corn seed provider for
varietal tolerance to 2,4-D applications. Apply prior to 4 leaf stage of corn.
Note: The above mixes are those listed on the glyphosate labels only.
Monsanto also supports the following mixes that are not on the Roundup brand labels to manage glyphosate resistant
kochia and other labelled weeds at the pressed burnoff timing prior to planting soybean. Apply mixes according to the
most restrictive use limitations for either product:
• Herbicides: Heat (also glyphosate tolerant canola volunteers), Valtera, Authority, Authority Charge.
Adding ingredients in the correct order is critical for optimum performance. Check labels of products to be mixed for
directions. See the general guidelines for mixing pesticides for more information.
Application Information:
• Water Volume:
º Ground: Use 20 to 40 L per acre in most situations; use of the lower volume may improve control when hard water
(Ca or Mg) or iron (Fe) ions are present (See Effects of Growing Conditions below). For certain crop situations,
perennial weeds and tank mixes may require up to 120 L per acre of clean low ion water.
º Aerial: Use 8.1 to 20 L per acre for registered preharvest uses only (see Aerial Application below). Minimum 20 L per
acre for preseed, fallow, glyphosate tolerant crops and post-harvest treatments with Roundup WeatherMax only.
Refer to specific weed control situations or labels for more information on water volumes and adjuvants.
• Nozzles and Pressure: Use 30 to 40 psi (200 to 275 kPa) when using conventional flat fan nozzles. Low drift nozzles
may require higher pressures for proper performance. Use nozzles and pressure designed to deliver thorough, even
coverage with ASABE medium droplets for ground applications and ASABE coarse droplets for aerial applications.
