Studies conducted to determine life history and starch allocation of common reed (Phragmites australis), and evaluate haplotype susceptibility to aquatic labeled herbicides. Twelve 0.1 m2 samples were taken from four sites in the Mobile River delta from January 2006 to December 2007. Samples separated into above and belowground biomass dried and weighed. Starch determination used the amylase/amyloglucosidase method. Biomass decreased with decreasing temperature. Aboveground biomass was 2200 and 1302 g m2 in October 2006 and December 2007. Belowground biomass was 1602 and 1610 g m-2 in November 2006 and December 2007. Aboveground starch was highest in December of 2006 and November of 2007. Belowground starch peaked in August of 2006 and September of 2007. RFLP methodologies were used to identify populations of I and M used for herbicide sensitivity screening. No difference detected in the susceptibility of haplotypes. Glyphosate, imazapyr, and triclopyr are effective herbicides for common reed control.
