Spray immediately after planting. Use lower rate on light soils. Shallow cultivation usually will improve weed control. Do not plant any crop except those specified on the label the following year. Do not apply more than 2.0 pounds of atrazine or simazine in any one year. Use a 1:2 ratio of atrazine to simazine on more severe annual grass problem areas. |
| Same as above. | Preemergence | Atrazine 1.0-1.5 lb
+ simazine 1.0-1.5 lb |
Atrazine 4L 1.0-1.5 qt
or 90W 1.1-1.6 lb + Princep 4L 1.0-1.5 qt or 90W 1.1-1.6 lb |

| Barnyardgrass, carpetweed, crabgrass, foxtail (giant, green, yellow), goosegrass, nutsedge (yellow), panicum (fall), pigweed, pusley (Florida), signalgrass, and witchgrass | Preplant incorporated | s-metolachlor 0.95-1.6 lb | Dual II Magnum/Cinch 7.64EC
