Conventional active substances used for cotton and grain seed treatment belong to toxicity classes II–III, negatively affecting soil fertility and agricultural product quality. This study focuses on low-toxic (class IV) preparations. Objective. To study the pilot-scale production technology of a granulated multifunctional composition based on monomethylolurea, copper and zinc phytocompounds, mono- and dicalcium phosphate, and phosphate monoethanolamine. Methods. Experiments were conducted at the pilot plant of LLP “Scientific and Production Association Ana-Zher” using a screw granulator (L = 4.7 m, D = 0.8 m). Results. The optimal solid-to-liquid composition ratio was 0.80:0.20. At a 30-min residence time, the yield of 1–4 mm granules was 83% for MMM and FSCu • MCP (150 kg/h; moisture 0.95%), 85% for MMM and FSZn • DCP (160 kg/h; 0.93%), and 82% for MMM • FMEA (145 kg/h; 0.94%). Conclusion. The selected parameters ensure production of a high-quality granulated preparation with favorable physicochemical and commercial properties.
