FIELD: agrochemistry.
SUBSTANCE: disclosed is a method of producing an adduct [N,N'-bis(dimethylaminomethyl)thiourea acetic acid]copper sulphate pentahydrate and its use as an agent with growth-stimulating and fungicidal activity for increasing crop capacity of spring wheat. As a result of the reaction of thiourea, an aqueous solution of dimethylamine and paraformaldehyde, taken in ratio of 1:3:2, for 3 hours while heating 40 °C in the medium ethyl alcohol : water=1:10 obtained in situ N,N'-bis(dimethylaminomethyl)thiourea. Further, acetic acid and copper sulphate are added, taken in ratio N,N'-bis(dimethylaminomethyl)thiourea : CH3COOH : CuSO4⋅5H2O = 1:1:1, with constant stirring and temperature of 20 °C for 0.5 hours. Target product is obtained with output of 95%.
EFFECT: inventions make it possible to increase yield of spring wheat by 12.3% in comparison with control.
