The mix was fumigated with Dazomet
(Bazamid[R] 98%, BASF Corp.
In contrast, federal nurseries have turned almost exclusively to dazomet (Basamid), because of federal pressure to use the least toxic materials and also because these nurseries are in the more-arid regions of the western United States, where spring fumigation can be carried out more easily.
As of April 2013, the Environmental Protection Agency (EPA 2013) listed five fumigant alternatives (and no nonfumigant alternatives) for the industry: dazomet, metam sodium (Vapam, Busan), chloropicrin (Pic), dimethyl disulfide (DMDS), and 1,3-dichloropropene (1,3-D), and two combinations of these: 1,3-D and chloropicrin (Telone, Pic-Clor 60) and metam sodium and chloropicrin.
Sulfoxidation of the soil fumigants metam, methyl isothiocyanate, and dazomet.
Metabolism in rats and mice of the soil fumigants metham, methyl isothiocyanate, and dazomet.
Copper naphthenate was slightly less effective as a dazomet accelerant, but slightly better than dazomet alone.
In an effort to identify other, more easily handled systems, dazomet (tetrahydro-3,5-dimethyl-2H-1,3,5-thiodiazine-2-thione) was examined for its potential as a fumigant.
Fumigants include methyl isothiocyanate (MITC), MITC generators, me-tasodium, dazomet
and halogenated hydrocarbons (e.
AMVAC will also be developing the product for use in other crops such as lettuce & spinach and will be responsible for the re-registration of dazomet
in the United States.
, the active ingredient of Basamid, has no impact on the ozone making it an ideal alternative to methyl bromide which is currently being phased out worldwide due to its effect on the ozone layer.
The Malawian Agricultural Research and Extension Trust is working to raise awareness among the country's farmers about the hazards of using the chemical and about alternatives to using it, which include soil-less culture of tobacco plants and use of more benign chemicals such as dazomet
