Replacing methyl bromide
The chemical is considered a "drop-in" replacement for methyl bromide, as it provides the same broad spectrum of nematode, weed, insect, and pathogen control. Since the phaseout, some growers have used a combination of fumigants to achieve the same broad spectrum of control that methyl bromide provided. The new preplant …

This is an "infant" plant disease. In typical cases, infection occurs at the soil line in the hypocotyl and results in softening and rotting at the base of the stem right on the soil surface. In other cases, the objects of the infection are the germs of the seeds, before their emergence on the surface of the soil.
