Summary

The new approach on emulsified nutritive fluids formulation open a way to graft multifunctional properties as growth enhancing and fungi repelling to common foliar fertilizes. Selection of the overbasic potassium salts of naphthenic and oleic acids as organic phase carrier in these formulations has been grounded on their proofed antifungal attributes. In this paper the diffusion method of antimicrobial susceptibility test was adapted to quantify antifungal properties of the potassium overbasic naphthenates and oleates as intermediary products in the nutritive fluids manufacture. The results have validated the proficient fungicide effects of potassium overbasic naphthenate with overbasicity 4/1 and the mild behavior of potassium overbasic oleate as contact fungicide.
