| Weed Problem | Chemical rate per acre | Product per acre | Remarks |
|---|---|---|---|
| Contact kill of most annual weeds and weeds listed in previous tables for specific residual herbicides | Paraquat 0.5-1.0 lb
+ surfactant + clomazone, s-metolachlor, alachlor, dimethenamid-p, or pendimethalin (residual grass control) + linuron, flumetsulan, imazaquin or metribuzin |
Gramoxone Inteon 2.0-4.0 pt
+ surfactant as specified by label + Command ME, Dual II Magnum/Cinch, MicroTech, or other alachlor formulations, Outlook, or Prowl + Linex/Lorox, Python, Scepter, or Sencor |
Use 2.0-2,5 pints/acre for weeds 1-3 inches tall, 2.5-3.0 pints/acre for weeds 3-6 inches tall, and 3.0-4.0 pints per acre for weeds over 6 inches tall. Weeds over 6 inches tall may not be controlled. Apply to small-grain stubble after planting and before emergence of soybeans. Use 20 to 60 gallons of diluted spray per acre. As the density of the stubble or crop residue increases, the spray gallonage should increase to ensure complete coverage and kill. Do not graze or feed treated forage to livestock. Observe all precautions, rates of application, and weeds controlled on respective labels. |
| Kill of most annuals and some perennials and weeds listed in previous tables for specific residual herbicides | Glyphosate 0.5-5.0 lb
Approved cokmbinations: Tank-mix with Dual II Magnum/Cinch, MicroTech, or Outlook with either Linex/Lorox, Python, Scepter, or Sencor |
Roundup Weather Max 0.5-3.1 qt
or Touchdown Total 0.375-3.6 qt or other labeled glyphosate formulation |
Refer to previous table. At the normal time of planting soybeans, johnsongrass and bermudagrass will not be at the proper stage of growth for effective control. Do not feed or forage glyphosate-treated crops within 8 weeks after application. See label for specific weeds controlled. Use 1.0 pound per acre for control of annual broadleaf weeds and grasses up to 6 inches high and 1.5 pounds per acre for annual broadleaf weeds and grasses more than 6 inches high. Applications with fan-type nozzles generally have been more effective than with flood-type nozzles. Use 3.0 to 10 gallons of water per acre and low-rate technology instructions for most economical glyphosate use rates or 10 to 40 gallons of water using high-volume instructions and corresponding glyphosate rates. Observe all precautions, rates of application, and weeds controlled on respective labels. Touchdown Total is available as a non-surfactant containing formulation called Touchdown HiTech. Sequence is a glyphosate + Dual II Magnum package-mix. Use rate is 2.5-3.5 pints/acre |
