Quantification and Identification of Active Microorganisms in Microbial Plant Protection Products


All Microbial Plant Protection Products (MPPP) that were on the Danish market in January 2004 were investigated with the aim to quantify and identify the active microorganisms in the MPPP and detect contaminating bacteria. Deviations in quantity as well as identity were found for some MPPP. In some MPPP based on Trichoderma sp. the occurrence of contaminating microorganisms was higher than specified by the producers. This may have implications for health or environmentally related risks.
