The invention provides compounds for use in inhibiting a microbial alternative oxidase (AOX) and/or cytochrome bc.sub.1 complex. The invention extends to the use of such inhibitors in agrochemicals and in pharmaceuticals, for treating microbial infections, including fungal infections.

The present invention relates to compounds of Formula (I), or an agronomically acceptable salt of said compounds wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are as defined herein. The invention further relates to herbicidal compositions which comprise a compound of Formula (I) and to the use of compounds of Formula (I) for controlling weeds, in particular in crops of useful plants.

A biocide blend can be used in an oil or gas operation. The biocide blend can include a first biocide of a formaldehyde-releasing biocide and a second biocide of a quaternary ammonium compound. The formaldehyde-releasing biocide can release formaldehyde after introduction into a wellbore. The first and second biocide can possess at least one property that is the same. The first biocide and/or the second biocide can maintain biocidal activity for extended periods of time in high salinity wellbore fluids, be thermally stable, and less expensive than other biocides.
