Biological responses to advanced foliar fluidic nutrients applications

Abstract

The new approach on emulsified nutritive fluids formulation opens a path to graft multifunctional properties such as growth enhancing and fungi repelling to common foliar fertilizes. Selection of overbasic potassium salts of naphthenic and oleic acids as organic phase carrier in these formulations has been grounded on their proven 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 manufacture of nutritive fluids. 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.
