Effects of Monosulfuron on Mixotrophic Growth and Photosynthetic Pigments of Auabaena flos-aquae Breb. Exposed to Different Light Intensities

Exposed to three light intensities, the six concentrations of monosulfuron tested can significantly inhibit the growth of Auabaena flos-aquae in a dose-dependent manner. The herbicide monosulfuron appeared to have different effects on the synthesis of photosynthetic pigments. A. flos-aquae had different degrees of sensitivity to monosulfuron with the most sensitive light intensity being 4000-lux followed by 3000-lux and 2000-lux.
