  1. Water primrose: Chemical control using herbicides

    A controlled, replicated laboratory study conducted in 2007 in the USA (Champion et al. 2008) found that the herbicide triclopyr TEA (triethylamine) stopped the growth of young cultivated creeping water primrose Ludwigia peploides in comparison to untreated plants. Plants stopped growing and were damaged at concentrations of 0.25% by volume and above. Within two months, 0.25 % triclopyr TEA killed 100 % of treated creeping water primrose. Creeping water primrose seedlings were collected from the wild and cultivated in glasshouses. The plants were grown in water-filled 40 litre tubs containing a bed of sand for at least two months. Herbicide was applied to run off at between 0.25% and 5.00% concentration by volume. Ten plants were tested at each concentration and monitored regularly for signs of herbicide damage. Ten plants were left untreated as controls.
