(b) 100 hives of bees were lost probably caused by drift of carbaryl from a nearby orchard.

His hives were placed along Long Forest Road near Bacchus Marsh to work the yellow box in the adjacent mallee forest. An orchardist on the south side of the Western Highway, several kilometres away down the valley was observed to be spraying the previous day.

Carbaryl is commonly used by orchardists to promote fruit drop, but the owner denied having used it, saying her intended to use in a few days time.

Carbaryl is extremely toxic to bees. Dead bees were analysed by the DAV laboratory as having 0.8 – 0.7 ppm carbaryl residue but no organochlorine and no organophosphate residues.
