GROWTH RETARDANT FOR VEGETATIVE ORGANS OF CUCUMBERS AND PREPARATION METHOD THEREOF Russian patent published in 2016 - IPC A01N59/20 A01N43/647 A01P21/00 

FIELD: agriculture.

SUBSTANCE: composition is intended for germination and growth of cucumbers. Retardant growth has molecular formula C₉H₁₈Cu₂N₁₄O₁₀ and consists of active substance, 4H-1,2,4-triazol-4-yl([4H-1,2,4-triazol-4-yl [(4H-1,2,4-triazol-4-yl-amino)methyl]amino]methyl] amino)methanol coordinated with ions of copper(II). To obtain retardants reacting copper(II) nitrate with 4H-1,2,4-triazol-4-yl([4H-1,2,4-triazol-4-yl[(4H-1,2,4-triazol-4-yl-amino)methyl]amino]methyl] amino)methanol (L):

2Cu(NO₃)₂+3H₂O+L→(CuOH)₂L(NO₃)₂·H₂O↓+2HNO₃, obtained by reaction of condensation of 4-amino-1,2,4-triazole with formaldehyde in aqueous medium at temperature 60 °C for 45 minutes

.

EFFECT: higher efficiency of growth of cucumbers.
