Spray to Swath Interval Calculator
The Spray to Swath Interval is the minimum number of days that must pass between product application and cutting your crop by swathing or straight-cutting. On farm chemical labels, you’ll see it referred to as the Pre-Harvest Interval or PHI. Cutting before this interval has lapsed can leave unacceptable residues on harvested seed.
When tank mixing, each tank mix partner is applied in accordance with its registered product label. In cases where information on the tank mix partner labels differs between them, the most restrictive directions must be followed.
