A METHOD FOR IMPROVING THE HEALTH OF A PLANT USING AT LEAST ONE (THIO)PHOSPHORIC ACID TRIAMIDE SUCH AS N-(N-BUTYL)THIOPHOSPHORIC ACID TRIAMIDE (NBPT) AND/OR N-(N-PROPYL)THIOPHOSPHORIC ACID TRIAMIDE (NPPT) ESSENTIALLY IN ABSENCE OF A UREA-CONTAINING FERTILIZER

摘要

A method for improving the health of a plant, comprising treating a plant growing on soil or soil substituents and/or treating the locus where the plant is growing or is intended to grow with at least one (thio)phosphoric acid triamide according to the general formula (I) wherein X is oxygen or sulfur; R1 and R2 are - independent from each other - H, substituted or unsubstituted 2-nitrophenyl, C1 to C20 alkyl, C3 to C20 cycloalkyl, C6 to C20 heterocycloaryl, C6 to C20 aryl, or dialkylaminocarbonyl group wherein R1 and R2 together with the nitrogen atom linking them define a 5- or 6-membered saturated or unsaturated heterocyclic radical, which optionally comprises 1 or 2 further heteroatoms selected from the group consisting of nitrogen, oxygen, and sulfur, wherein improved plant health is determined by - increased crop biomass or crop yield, - improved plant vigor, - improved plant quality, and/or - improved tolerance or resistance of the plant to abiotic stress factors.
