Use period is April 30 to June 30, 1999. Spartan may be tank-mixed with Prowl. FMC intends for Spartan to be used by growers who agree that FMC will not be help responsible for failure of performance or crop damage from use of the product in a single preplant incorporation or preemergence application. In addition to kochia, Spartan may also control other small-seeded broadleaf weeds, such as, annual smartweeds, Russian thistle, wild buckwheat, nightshade species, biennial wormwood, marshelder, pigweed species, and common lambsquarters. Spartan may also suppress foxtail.
Spartan has NO perennial weed control.
Consistent control of sensitive broadleaf weeds, grass suppression, and marginally controlled weeds greatly depends on rainfall shortly after application and before weeds emerge. At least one inch of rain is required after application for optimum weed control. If no rain occurs after application, a light harrowing or rotary hoe operation may destroy emerging weed seedlings and help active the herbicide. Spartan will not control weeds once emerged. Follow the following crop rotation guidelines when rotating crops the year following Spartan application.
