A process for preparing dibromonitro-alcohols, and mixtures thereof with bromonitro-alcohols, is disclosed in which dibromonitromethane, and optionally bromonitroethane, is reacted with a C.sub.1 -C.sub.3 aldehyde in aqueous solution at an acid pH, preferably between about 4.0 and about 7.0. An aqueous solution of the aldehyde is prepared and the pH adjusted to the desired acid range by addition of sodium bicarbonate, and the dibromonitromethane, which may include bromonitromethane, is added thereto. The dibromonitro-alcohol product is isolated as a separate phase from the reaction mixture.

2-(2-bromo-2-nitroethenyl)-furan can be used as an antimicrobial in broad spectrum of uses. A novel process for preparing 2-(2-bromo-2-nitroethenyl)-furan has been found in which furfural is reacted with bromonitromethane using a primary amine or primary amine salt as a catalytic agent to produce an intermediate product which is dehydrated in the presence of acid to the desired product. An antimicrobial composition comprising 2-(2-bromo-2-nitroethenyl)-furan and a carrier is also disclosed.

A method for the treatment of nematodes includes the impregnation of soil with a nematicidal amount of bromonitromethane. The application is made at rates of 1 to 40 quarts of bromonitromethane per acre of soil. The bromonitromethane has excellent nematicidal effect at surprisingly low concentrations, is cost effective, and is not phytotoxic. The bromonitromethane may be suspended in a variety of liquid or solid carrier systems, and is applied to the soil by methods including mixing, fumigation and injection.
