EVALUATION OF TRICLOPYR TRIETHYLAMINE FOR THE CONTROL OF WETLAND WEEDS

摘要

Several experiments evaluating the susceptibility of aquatic and wetland weeds to triclopyr TEA were carried out using potted plants. Seedlings of grey willow (Salix cinered), alder (Alnus glutinosd) and purple loosestrife (Lythrum salicaria), and cuttings of crack willow (S. fragilis), primrose willow (Ludwigia peploides), water celery (Apium nodiflorum), water cress (Nasturtium officinale) and monkey musk (Mimulus guttatus) were collected in the field and grown in cultivation. At least 2 months after potting up, triclopyr TEA was applied to run off at rates between 0.25% and 5% v/v. This resulted in excellent control of all weeds at all rates, except for purple loosestrife, which was not controlled well at the lowest rate.
