TECHNOLOGY FOR OBTAINING BIOLOGICALLY ACTIVE POLYMER PREPOROTIVE FORMS OF COPPIERCHIT FOR SEED PRODUCTION

Abstract

A technological scheme for producing a biologically active polymer – chitosan, obtained from pupae, silkworms, and copper (II) has been developed. Optimal parameters of obtaining of 9–12% of coppercontained polymer metal complexes under the technological conditions at 22°C, pH=6, and the molar ratio Chit–NH2: Cu2+1:1 were identified. On the basis of this technology, a 20 l polymeric form of Copprierchit preparation has been developed. The fungicidal and stimulating properties of the ecologically safe preparation of Copprierchit were studied in laboratory conditions. The structure and composition of the obtained biopolymers were confirmed by UV spectroscopy and elemental analysis. The results show that the polymer composition has high biological activity with 1% polymer metal complex and 0.5% polyacrylamide.
