Effect of Trifloxysulfuron sodium on growth of the mangrove, Avicennia marina

Plants were exposed to 6 concentrations of trifloxysulfuron for 28 days followed by 56 days of recovery after removal of the herbicide. During this time, assessments were made of appropriate parameters including shoot height, leaf number, fresh and dry weight.
This study was designed to evaluate the effects of the sulfonylurea herbicide, trifloxysulfuron,on the growth of the mangrove Avicennia marina under tidal conditions.
Data was analysed to detect significant deviations in these parameters from control values, and thus determine the NOAEC (no-observed adverse effect concentration).
