  • Application Rate

    Application flexibility adds value. Weather, equipment and scheduling can cause timely delays. SureStart II herbicide can be applied from preplant through early postmergence, providing growers with the flexibility to overcome the unexpected. Surestart II is tank mix compatible with glyphosate, atrazine, 2,4-D and other commonly-used herbicides (refer to label for complete list). SureStart II doesn't contain atrazine so it's ideal for use in atrazine-restricted areas, and can be used in one- or two-pass weed control programs.

  • Crop Rotation


    According to university research, using a two-pass weed control program with SureStart® II followed by glyphosate can provide an average of 7 percent additional yield per acre when compared with glyphosate alone. SureStart II controls early season weeds that compete for sun, water and nutrients. Up to six weeks of residual control maximizes glyphosate spray window and improves effectiveness of post spray application made on smaller, easier-to-control weeds.

    3Dry beans include: adzuki, kidney, lima (dry), navy, and pinto.
    4Pea includes: blackeyed, chick, cow, Crowder, field, pigeon, and Southern.
