Parrot’s feather: Use of herbicides - other herbicides Control of Freshwater Invasive Species

A small, replicated, randomized, controlled laboratory study conducted in the USA (Richardson et al. 2016), found that a new herbicide tested under the code SX1552 (chemical name: 4-amino-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)-5-fluoro-pyridine-2-benzyl ester; common name florpyrauxifen-benzyl) reduced parrot’s feather Myriophyllum aquaticum growth. Four weeks after exposure, the dry weight of parrot’s feather plants treated with SX1552 was reduced to less than 80% of the dry weight of untreated plants (data not reported). Experiments were based on laboratory stock plants grown in 15 l plastic containers. Herbicide concentration ranged between 3 and 81 µg/l. Each SX1552 concentration was tested in four plants. Plants were grown for about one week prior to treatment.
