Ecologically acceptable measures and means for plant protection are explained. The implemented agrotechnical measures and protection measures in the ecological cultivation of plums at The family farm Sabo were presented. The goal of the final paper is to monitor the appearance of harmful organisms during the ecological cultivation of plums at The family farm Sabo in 2023, based on regular inspections, and to describe the implemented methods of their suppression.
