Abstract: The composition contains a fundamental active ingredient consisting of the association of thymol, eugenol and cinnamaldehyde, a secondary active ingredient consisting of the association of cuminaldehyde, geraniol, vanillin, borneol, menthol, anethole, terpineol, limonene and different glycosides contained in the essences of mustard and jasmine, a surface-active selected among the different families accepted as emulsifying food additives and an oligosaccharide selected among the mono-oligosaccharides, fructo-oligosaccharides, phyco-oligosaccharides proceeding from algae extracts or vegetable tissue. The composition that has just been described is applied to fruit and vegetables in a diluted bath or in solid form incorporated into the waxes that are usually used in post-harvest treatments.

Abstract: It consists of using a precursor compound of cyclic AMP, or an inhibitor compound of the enzymes of the Phosphodiesterases family, or a stimulating compound of the enzymes of the Adenyl-Cyclase family, or an agonist compound of the &bgr;-adrenergic receptors to which arachidonic acid or a prostaglandin is added. The composition object of the invention can be presented mixed with mineral fertilizers (such as amonic nitrate, monopotassium phosphate, etc.), with phytoregulators (such as cytoquinines, auxines, giberelines, polyamines, n-ethanolamines, sugars . . . ) or with any type of phytosanitary product (such as fungicides, herbicides etc.). The composition object of the invention can be formulated with tensoactive agents (such as Tween 80), moistening agents etc. The composition object of the invention can be applied to any species of plant and at any point in its life cycle.
