METHOD FOR PRESOWING TREATMENT OF SUGAR BEET SEEDS Russian patent published in 1999 - IPC

FIELD: agriculture, in particular, seed stocking enterprises for presowing treatment of seeds of sugar beet, rape, corn, sunflower etc. SUBSTANCE: method involves forming biologically active nutrient and fungicidal medium on surface of uncoated seeds for providing complex beneficial action upon growing processes in germ, for suppressing pathogenic symptoms on seed surface; increasing uniformity of components of coating composition applied on seed surface by dispersing it through nozzles, and for protecting from inhibiting action of toxic insecticides contained in coating composition. Aqueous suspension of coating composition contains liquid microfertilizing composition in an amount of 6-8 l per 1 ton of seeds. Coating composition is prepared on the base of two solutions, which are applied on seeds having basic moisture content of 13-14.5% in two successive layers, with following drying to basic moisture content upon applying of each layer. The first applied layer is aqueous suspension containing fungicide, growth promoter such as microfertilizing composition, film forming substance and water. The second layer applied contains insecticides and film forming polymers. EFFECT: increased efficiency by forming nutritive and fungicidal medium on seed surface, improved uniformity of layers applied on seed surface and reduced inhibiting effect of insecticides contained in second layer. 4 cl, 1 dwg, 2 tbl
