A reactive antibacterial compound and a preparation method thereof are provided herein. The reactive antibacterial compound is represented by the general formula (I) or (II):

##STR00001##

wherein R.sub.1 represents OCN-L-NHCOOR, OCN-L-NHCONHR, OCN-L-NHCOSR, OCN-L-COOR, or OCN-L-COONHR. G1 represents OCN-M-NHCOOG, OCN-M-NHCONHG, OCN-M-NHCOSG, OCN-M-COOG, or OCN-M-COONHG. L, M, R and G independently for each occurrence represent divalent alkyl and cycloalkyl having from 1 to 18 carbon atoms, optionally substituted by up to 18 heteroatoms. R.sub.4 and G.sub.4 independently for each occurrence represent a divalent alkyl and cycloalkyl having from 1 to 18 carbon atoms, optionally substituted by at most 18 heteroatoms. G.sub.2 and G.sub.3 independently for each occurrence represent H, F, Cl, Br, I, OCH3, OCH2CH3, OPr, CN, SCN, NO, NO2, a monovalent unsubstituted or substituted alkyl, cycloalkyl, or aryl having from 1 to 7 carbon atoms. Z and X independently for each occurrence represent COO, SO3, or OPO2OR.sub.5. R.sub.5 represents a monovalent unsubstituted or substituted alkyl, cycloalkyl, or aryl having from 1 to 6 carbon atoms.

A first aspect of the invention is an agricultural composition comprising nanoparticles, an agrochemical active ingredient in the nanoparticles, and optionally (but in some embodiments preferably) a carrier for the nanoparticles. In some embodiments, the nanoparticles are viral particles or capsids, particularly plant viral particles or capsids. In some embodiments, the carrier comprises an inert or biodegradable carrier (e.g., a solid carrier) to which the nanoparticles are bound or in which the nanoparticles are suspended. In some embodiments, the carrier comprises inert or biodegradable polymer fibers.
