A plant treatment composition for application of an anionic exogenous chemical substance such as glyphosate to foliage of a plant is provided. The composition comprises, in addition to the exogenous chemical substance, 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)
R—NR—((CH2)p—CHR4—NR)q—R (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, ester, thioester and amide 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. The exogenous chemical substance and amine compound(s) of formula (I) are dissolved or dispersed in an agronomically acceptable liquid carrier, preferably water. Also provided are a liquid concentrate composition which, upon dilution with water, forms a plant treatment composition, and a process for making such a liquid concentrate composition. Plant treatment compositions of the invention are useful for eliciting a biological activity, for example herbicidal activity, in a plant.
提供一种植物处理组合物,用于将阴离子外源化学物质(如草甘膦)应用于植物叶片。该组合物除了包括外源化学物质外,还包括一种或多种氨基化合物,每种化合物具有n个可质子化氨基团,其中n至少为1,具有下列式(I)R—NR—((CH2)p—CHR4—NR)q—R (I)其中q为0至9的整数,每个p独立为1至5的整数,每个R4基团独立地为氢或C1-5烷基基团,R基团独立地选自氢、C1-5烃基团和线性或支链、饱和或不饱和的C6-22烃基或酰基链,该链未经取代或在一个或多个碳原子上与一个独立选择的羟基、羧基、氨基、巯基和氰基等功能团之一取代,以及未经中断或在一个或多个独立选择的醚、硫醚、亚砜、酯、硫酯和酰胺键之一中断,以至少有6个碳原子的未中断烃基段终止;但至少有一个到三个R基团是这样的C6-22烃基或酰基链,其中至少有一个被取代和/或中断。式(I)的外源化学物质和氨基化合物溶解或分散在农学上可接受的液体载体中,最好是水。还提供了一种液体浓缩组合物,稀释后与水形成植物处理组合物,以及制备这种液体浓缩组合物的过程。该发明的植物处理组合物可用于引发植物中的生物活性,例如除草活性。
