Scientists trying to help Florida growers find a replacement for methyl bromide are studying an alternative soil treatment that uses molasses as one of its ingredients. Farmers have been using methyl bromide since the 1930s to control a broad spectrum of nematodes, pests and pathogens. But because methyl bromide depletes Earth's stratospheric ozone layer, growers worldwide are being required to find a replacement. That's a tall order in Florida, where the sandy soils limit organic alternatives and the mild winters serve as a safe harbor for many nematodes, weeds and pathogens.
