METHOD FOR DETERMING SYNERGETIC EFFECT OF SURFACE-ACTIVE SUBSTANCES IN HERBICIDE DISPERSION SYSTEMS Russian patent published in 2010 - IPC A01N25/04 A01N25/30 A01P13/00 

FIELD: agriculture.

SUBSTANCE: blending reactant, first surface-active substance (FSAS) with organic solvent, separately blending reactant, second surface-active substance (SSAS) with organic solvent, separately blending reactant, mixture of first and second surface-active substances with organic solvent, separately emulsification of received concentrates in water, received emulsions definition in hours, by quantity of fallen coagulate in a half-life period, presentation of these indicators in percentage (% actual RE) and Synergism's calculation under the formula: % actual RE - % calculation RE, where % calculation RE = % actual RE FSAS I + % actual RE SSAS - (% actual RE FSAS × % actual RE SSAS): 100.

EFFECT: invention makes it possible to realise the specified appointment, to optimise the maintenance of SAS, to raise herbicidal activity of preparations.
