Table 2.4-15. Soybean herbicide rotational restrictions.

• The information listed in this table is our interpretation of label statements or a “best-guess” estimate. Rotational intervals are as follows, but they may be influenced by many factors, such as the addition of other residual herbicides, soil type, and soil pH. Do not use these herbicides unless all rotational restrictions are understood. Consult the label for a different time interval if two or more of these materials are applied during the same season. Herbicide labels are constantly changing; therefore, this list is not a substitute for the most recent herbicide label.

Key: NR = No Restriction; NY = Next Year; SY= Second Year following application; AH = After Harvest Read the label for additional restrictions due to rate, rainfall, soil, pH, and application rate. Transplanted. Corn hybrids that are classified as IMI-corn or as tolerant (IT) or resistant (IR) to Scepter and/or other imidazolinone herbicides such as Pursuit may be planted in the spring of the year following Scepter or Pursuit application regardless of rainfall or time interval from chemical treatment to corn planting. Plus successful field bioassay. Treated seed. Plant below herbicide zone. 10 months if ≤ 0.3 oz/A
