General
- Thiram is a
non-systemic dimethyl dithiocarbamate fungicide.
- Thiram is white or
yellow crystalline solid with a characteristic odor at room temperature.
- Thiram is a peptizing
agent in sulfur-modified polychloroprenes.
- Thiram is available
in dust, flowable, wettable powder, water dispersible granules, and
water suspension formulations.
- Thiram is not
persistent in soils and also is nearly immobile in clay or highly
organic soils.
Process
- The intracellular
oxidation of dimethyldithiocarbamate anions to thiram, which in turn
oxidizes intracellular glutathione(GSH).
- The metabolic
interconversion of thiram and dimethyldithiocarbamic acid and the
biochemical pathway may control the metabolic fate of compounds in S.
cerevisiae.
-
Thiram-tetramethylthiuram disulphide – a chelator of heavy metals,
inhibited DNA synthesis and induced apoptosis in cultured bovine
capillary endothelial cells.
- The isolation and
primary characterization of microbial species obtained from enrichment
soil cultures capable of utilizing tetramethylthiuram disulfide(TMTD).
Application
- Thiram [bis(dimethylthiocarbamoyl)
disulfide] was one of the first dithiocarbamate fungicides used for the
control of plant diseases.
- Thiram, tetramethyl
thiuram disulphide an organic sulphur compound is a fungicide commonly
used for treating corn and other grains intended for seed purposes and
also for storing food grains.
- Soil samples treated
with thiram, eptam or vernam yielded secondary amines, but no
nitrosamines.
- A fungicide with
Tirama agent was applied to the two different economically important
culture species of corn (Zea mays L.) in different concentrations and
morphological and physiological effects of this fungicide on seedlings
grown from seeds were analyzed.
Technology
-
TMTD[tetramethylthiuram disulfide]-degrading microorganisms were
isolated by the enrichment and adaptation techniques.
- HPLC is the most
preferred analytical technique used in pesticide analysis. The analysis
of thiram formulations and technical products has been carried out by
HPLC using methanol.
- A number of
techniques such as Spectrophotometric1, chromatography2, voltammetric3,
polarographic4, capillary electrophoretic5, etc., has been used for the
detection and analysis of thiram.
- Thiram found on
silver surface can be determined by surface enhanced Raman
scattering(SERS) technique.
