Study of Waterhyacinths Showing Possible Resistance to 2,4-D Chemical Control Programs
Abstract
The fact that heterostyly exists in waterhyacinths has been known for years, but a recent observation that long-style plants might be somewhat resistant to 2,4-D control resulted in the need for this study. To further evaluate the situation, the work involved field observations of midstyle and long-style populations, self- and cross-pollination studies, and herbicide treatments. Although long-style waterhyacinth plants do appear to be somewhat more resistant to 2-4-D than midstyle ones, this probably will not be a serious consideration in the Corps' aquatic plant control operations. However, the situation is very curious from a botanical standpoint and should be studied further.
