Abstract
Inorganic bromide in the sandy loam soils in glasshouses used for carnation culture at Dingley, Victoria declined from 34.1 μg Brg −1 following fumigation with bromomethane in 1985 to 4.2μg Brg −1 after flooding with 15cm of water. Soil pH increased with time after fumigation and flooding. In 1987 fumigation with bromomethane reduced numbers of Fusarium spp from 3.96 × 10 4cfug −1 to 8cfug −1. Populations of Fusarium varied significantly with sample site within the same glasshouse. When leaching of inorganic bromide in soil was prevented carnation plants accumulated toxic amounts of bromide.
