SOIL TEMPERATURE:

• If temperatures are too high, fumigant will volatilize and degrade too quickly.
• If temperatures are too low, fumigant will volatilize but not move through pore space as rapidly or as far.

As indicated previously in the charts for methyl bromide and Telone II, there are optimum ranges of soil temperature for fumigation and the range is somewhat wide for coarser than for finer textured soils. In some instances, labels indicate fumigation is possible at lower temperatures than indicated on the chart. In general, labels refer to the lowest temperature at which the product will kill nematodes and the charts refer to optimum movement of the product through soil.
