NOTES:
Another question about herbicide resistant weeds that frequently gets asked is "Does the use of reduced rates influence the rate of herbicide resistance development?". This question has been and will continue to be debated by most weed scientists. Some scientists agree that the use of reduced rates may hasten the development of resistant weeds while others do not. Some believe that reduced rates could possibly play more of a role in resistance when the resistance is due to many genes (multi-genic) as opposed to a single gene. At this time, it is probably more important to remember that selection pressure, not herbicide rate, is the most important factor that contributes to the development of herbicide resistant weeds. The goal of herbicide use as it relates to resistance management should be infrequent applications of the lowest rate that provides effective control.
