FIELD: agriculture.

SUBSTANCE: polyester capable of biological decomposition is used to treat seed grain. It represents a partially aromatic polyester, comprising: A) single acid component, containing a1) from 30 to 95 mole % of at least one aliphatic or at least one cycloaliphatic dicarbonic acid or their derivatives forming polyesters or mixtures from them, a2) from 5 to 70 mole % of at least one aromatic dicarbonic acid or its derivative forming polyesters or mixture of them and B) single diol component from at least one C₂- to C₁₂-alkanediol or one C₅- to C₁₀-cycloalkanediol or mixture of them. Molar percents of components from a1) to a2) make 100%. Liquid treatment composition includes (1) one partially aromatic polyester capable of biological decomposition, (2) at least one agrochemical active substance suitable to treat seed grain, (3) one dissolvent. Active substance is in the form of solid particles, having size from 0.1 mcm to 10 mcm. Suspension of agrochemical active substance suitable to treat seed grain, in which active substance is in the form of solid particles with size from 0.1 mcm to 10 mcm, is mixed with dispersion of partially aromatic polyester capable of biological decomposition. Seed grain is treated with polyester or composition.

EFFECT: invention makes it possible to reduce dust formation in treated seed grain.
