Larry Arrington, Dean Herbicides will often have rotational restrictions stating the amount of time that should be waited before planting a new crop after a herbicide is applied. This "recrop interval" has been determined by research to be enough time from the herbicide application to planting, in order to prevent injury from occurring to the new crop. If a crop is planted in a shorter time than the suggested recrop interval time, injury or crop death can occur. If herbicides are applied in mixture or in a sequential program, use the recrop interval that is most restrictive. Soil type, pH, temperatures, and rainfall may affect the recrop interval. The following tables are minimum intervals between herbicide application (at recommended rates) and recropping. Unless otherwise stated, recrop interval is listed in months. Always read the label prior to any herbicide use to determine if any other restrictions may alter the given recrop intervals.
