Abstract
A composition for application to foliage of a plant to elicit a biological effect is provided. This plant treatment composition comprises, dissolved or dispersed in water, an anionic exogenous chemical substance such as the herbicide N-phosphonomethylglycine, together with (i) one or more alkylether surfactants each having the formula EQU R.sup.12 --O--(CH.sub.2 CH.sub.2 O).sub.n ((CHR).sub.2 O).sub.m --R.sup.13 wherein R.sup.12 is an aliphatic saturated or unsaturated hydrocarbyl group having about 16 to about 22 carbon atoms, n is an average number of about 5 to about 100, m is an average number of 0 to about 5, one R in each --((CHR).sub.2 O)-- group is hydrogen and the other R is methyl, and R.sup.13 is a hydrogen, C.sub.1-4 alkyl or C.sub.2-4 acyl group; and (ii) one or more amine surfactants each having a molecular structure that comprises (a) a hydrophobic moiety having one or a plurality of independently saturated or unsaturated, branched or unbranched, aliphatic, alicyclic or aromatic C.sub.3-20 hydrocarbyl or hydrocarbylene groups joined together by 0 to about 7 ether linkages and having in total about 8 to about 24 carbon atoms, and (b) a hydrophilic moiety comprising an…
