The present invention is related to a plant biostimulant adjuvant and a method of treating a crop with a plant biostimulant adjuvant. The plant biostimulant adjuvant comprises a plant biostimulant comprising at least one of an amino acid or a peptide derived from a plant source. The plant biostimulant adjuvant also comprises an alkyl amine alkoxylate defined by the formula:

##STR00001##

wherein:
R.sup.1 is an alkyl of 6 to 22 carbons;
each R.sup.2 and R.sup.3 are each independently H or CH.sub.3.
n and m are each at least one and taken together n+m is 5 to 25;
and water.

Aqueous antimicrobial coating compositions are disclosed comprising at least one organosilane homopolymer, present as a distribution of polymer chain lengths, and optionally at least one amine. A method of preparing an antimicrobial coating comprises coating a surface with the aqueous antimicrobial coating composition and allowing the composition to dry into a film that exhibits residual antimicrobial efficacy against microorganisms even after mechanical abrasion of the coating. The organosilane homopolymer may comprise only 3-aminopropylsilanetriol homopolymer, mixtures of 3-aminopropylsilanetriol homopolymer, 3-chloropropylsilanetriol homopolymer and 3-(trihydroxysilyl)propyl dimethyloctadecyl ammonium chloride homopolymer, or any one of various unique organosilane homopolymers having multiple amine functionality.
