This study aimed to develop a system of biological protection methods for managing pests and diseases in order to support organic crop production under the conditions of southeastern Kazakhstan. Field experiments were conducted during the 2024 growing season across multiple crops, including wheat, barley, maize, and rapeseed. The study involved systematic pest monitoring, evaluation of microbial biopesticides, and deployment of natural enemies (Trichogramma spp., Bracon hebetor, Chrysoperla carnea). Applications were carried out using unmanned aerial vehicles (UAVs), and pest population dynamics were assessed at regular intervals to determine the efficacy of the treatments. Across all crops, 8 to 16 pest species were identified depending on the crop type. Biopesticide combinations demonstrated high effectiveness against key pests such as Plutella xylostella, Oulema melanopus, Eurygaster integriceps, Haplotrips tritici, and Schizaphis graminum, with control rates ranging from 84% to 100% after 7 days. The release of entomophages reduced populations of Helicoverpa armigera by up to 82.6% in later generations. Fungal and viral diseases were less prevalent but present on cereals and maize. The integrated use of microbial agents, beneficial insects, and UAV technology proved to be a sustainable and highly effective strategy for crop protection. These results provide a viable model for transitioning to environmentally safe pest control in organic farming systems across similar agroecological zones.
