COMPOSITION AND METHOD FOR TREATING PLANTS WITH EXOGENOUS CHEMICALS

摘要

Methods and compositions are disclosed wherein exogenous chemicals are applied to plants to generate a desired biological response. One embodiment of the present invention is a plant treatment compositon that comprises (a) an exogenous chemical; (b) a first excipient substance which is a compound or mixture of compouds having the formula R14-CO-A-R15, wherein R14 is a hydrocarbyl group having about 5 to about 21 carbon atoms, R15 is a hydrocarbyl group having 1 to about 14 carbon atoms, the total number of carbon atoms in R14 and R15 is about 11 to about 27, and A is O or NH; and (c) a second excipient substance which is an amphiphilic substance having a critical packing parameter greater than 1/3.
