Managing Glyphosate-Resistant Palmer Amaranth Research Meeting

Research Presentations

Segregation and what it means in Palmer amaranth and Colorado molecular and basic research. Glyphosate resistance in GA Palmer amaranth appears to be due to complex and not yet fully understood mechanism(s). Palmer amaranth produces an extremely high number of seed that may be moved easily from one area to another. High population numbers enhance the probability that resistant biotypes may occur and enhance the spread of resistant biotypes once they do occur. The following research may help in evaluating future cases of new glyphosate resistant weeds.
