Organic plant protection product from microalgae against
To release the fungicidal active substance the microalgal biomass was disrupted by a mechanical treatment in a ball mill. In the process it was possible to disrupt more than 95 percent of the cells. The subsequent conservation of the disrupted microalgal suspension was carried out by a thermal method through air-drying at low temperatures.
