If weather delays your burndown, turn to Spitfire. It is the only dicamba product (20 oz. rate) with an optional 7-day preplant interval between application and planting. For all other dicamba products the wait is 14 days or more. Countdown to planting begins after a Spitfire-treated field receives a minimum of one-half inch rain (or irrigation equivalent). All other dicamba products require one inch of rain. See label for full, detailed instructions.
