Signaling compositions, methods, and systems for effecting plant burndown and herbicide enhancement

A composition to be applied to plants and plant seeds comprising:

• an aqueous solution comprising an ester of the form
• wherein:
• R1 is a lower alkyl group containing between one and six carbon atoms, and a benzyl substituent;
• R2 is a lower alkyl group containing between one and six carbon atoms, and a benzyl substituent;
• R3 is one of a lower alkyl group, cyclopropyl, phenyl and alkyl substituted phenyl;
• the ester comprises at least one of 2-(N-Methylbenzylaminoethyl)-2-methylpropanoate (BMBE), 2-(N-Methylbenzylaminoethyl)-3-methylbutanoate (BMVE), 2-(N-Methylbenzylaminoethyl)-2,2-dimethylpropanoate (BMPE), 2-(N-Methylbenzylaminoethyl)-3,3-dimethylbutanoate (BMTE), 2-(N-Methylbenzylaminoethyl)phenylacetate (BMBA), 2-(N-Methylbenzylaminoethyl)phenoxyacetate (BMPA), and 2-(N-Methylbenzylaminoethyl) cylcopropanoate(BMCPA);
• n is an integer value from zero to four;
• and
• the composition produces a phytotoxic effect on a class of plants.
