Methods and compositions are disclosed in which exogenous chemicals are applied to plants, to generate a desirable biological response. An embodiment thereof is a plant treatment composition comprising (a) an exogenous chemical; (b) a first excipient substance which forms liposomes in aqueous dispersion and which consists of one or more compounds, each having (and) a hydrophilic portion comprising a cationic group and (ii) formulating a hydrophilic portion comprising two chains of hydrocarbyl or acyl, where about 40 to 100% of said chains in the composition are saturated linear alkyl or acyl groups having about 12 to about 18 carbon atoms. |
