Abstract:
A plant treatment composition for application to foliage of a plant to elicit a biological response, comprising an agronomically acceptable liquid carrier, wherein are dissolved or dispersed an anionic exogenous chemical substance and one or more amine compound(s) each having a number n of protonatable amino groups, n being at least 1, and having the formula (I)Râ€”NRâ€”((CH2)pâ€”CHR4â€”NR)qâ€”Râ€ƒâ€ƒ(I) wherein q is an integer of 0 to 9, each p is independently an integer of 1 to 5, each R4 group is independently hydrogen or a C1-5 alkyl group, and R groups are independently selected from hydrogen, C1-5 hydrocarbyl groups and linear or branched, saturated or unsaturated C6-22 hydrocarbyl or acyl chains that are (a) unsubstituted or substituted at one or a plurality of carbon atoms with a functional group independently selected from hydroxyl, carboxy, carbamyl, mercapto and cyano groups and (b) uninterrupted or interrupted by one or a plurality of functional linkages independently selected from ether, thioether, sulfoxide and thioester linkages, and terminated by an uninterrupted hydrocarbyl segment having at least 6 carbon atoms; with the proviso that one to three R groups are such C6-22 hydrocarbyl or acyl chains, of which at least one is so substituted and/or interrupted; said exogenous chemical substance being present in the composition in an amount sufficient to elicit the biological response when the composition is applied to the foliage of the plant at a rate from about 10 to about 1000 liters per hectare (l/ha); and said amine compound(s) being present in the composition in an amount such that the mole ratio of protonatable amino groups in such compound(s) to the exogenous chemical substance is about 0.05:1 to about 2:1.
