The primary and secondary effects of methabenzthiazuron on plankton were studied in outdoor microcosms (6 m3) for five months. Macrophytes, phytoplankton, zooplankton and the emergence of insects were examined. The herbicide was added to nine of the twelve mesocosms in concentrations ranging from 10 to 3371 μg a.i. l−1 in a single application. The other three ponds were used as untreated controls. Phytoplankton population dynamics fluctuated depending on light intensity, temperature, nutrients… CONTINUE READING
