In recent years, herbicide resistance has become a serious threat for soybean growers. Though the process cannot be stopped, certain management practices can slow its rate. In addition to glyphosate, the indigenous weeds horseweed, Palmer amaranth and common ragweed developed resistance against multiple herbicides. This project uses multiple spectrums of herbicides to effectively manage herbicide-resistant horseweed on the eastern shore of Maryland. A series of greenhouse, laboratory, and field studies focus on understanding the mechanism resistance in horseweed and its effective management.
