This disclosure describes biological pesticides that include biological mannosylerythritol lipids (MELs), and their application. Provided MEL-based pesticides are microbially produced by through microbial (fungal) fermentation of plant-based derivatives or plant-derived materials as a substrate. The biologically active components are obtained from multiple stage bio-processes including transformation, biochemical reaction, extraction, and other processing of raw materials. The synthesis, separation, concentration, purification, preparation of biological pesticides, and their application as a crop pathology treatment, are described. These biological pesticides may be used disease prevention and control for crops and other plants.
