Summary
Foliar application of sulfur (S)-containing agrochemicals offers a novel agricultural approach. Understanding the fate and combinations of these S compounds is crucial for efficient plant nutrition and crop yield.
Area of Science:
- Agricultural Science
- Plant Physiology
- Soil Science
Background:
- Plants absorb sulfate from soil via roots, converting it to cysteine.
- Foliar application allows direct uptake of sulfur (S) compounds by leaves.
- Various S-containing metabolites and non-metabolites are used in foliar sprays.
Purpose of the Study:
- To review the fate of foliar-applied S-containing compounds in plants.
- To discuss the rationale and efficiency of S-compound foliar applications.
- To highlight the importance of combining S-containing compounds for agricultural use.
Main Methods:
- Literature review on sulfur uptake and metabolism in plants.
- Analysis of S-compound fate after foliar application.
- Evaluation of the effectiveness of combined S-foliar treatments.
Main Results:
- Foliar application bypasses root uptake, delivering S compounds directly to leaves.
- Both S metabolites and non-metabolites (agrochemicals) are utilized by plants.
- Optimal combinations of S-containing compounds are essential for agricultural success.
Conclusions:
- Foliar application of S-compounds is a promising agricultural strategy.
- Understanding the transformation and interaction of these compounds is key.
- Strategic combinations of S-containing agrochemicals enhance agricultural utility.

01:22The Sulfur Cycle
44.5K
Sulfur, an important element in the chemical makeup of proteins, is recycled through the atmosphere and aquatic and terrestrial environments. Found in the atmosphere as sulfur dioxide (SO2), sulfur is released by decaying organisms, weathered rocks, geothermal vents, volcanos, and burning fossil fuels. It is deposited into the ecosystem, cycled through the biotic community, and either released back into the atmosphere as gas or deposited in marine sediment for long-term storage and eventual...

02:26Preparation and Reactions of Sulfides
4.8K
Sulfides are the sulfur analog of ethers, just as thiols are the sulfur analog of alcohol. Like ethers, sulfides also consist of two hydrocarbon groups bonded to the central sulfur atom. Depending upon the type of groups present, sulfides can be symmetrical or asymmetrical. Symmetrical sulfides can be prepared via an SN2 reaction between 2 equivalents of an alkyl halide and one equivalent of sodium sulfide.

01:22Electrophilic Aromatic Substitution: Sulfonation of Benzene
6.1K
Sulfonation of benzene is a reaction wherein benzene is treated with fuming sulfuric acid at room temperature to produce benzenesulfonic acid. Fuming sulfuric acid is a mixture of sulfur trioxide and concentrated sulfuric acid.

02:33Preparation and Reactions of Thiols
6.2K
Thiols are prepared using the hydrosulfide anion as a nucleophile in a nucleophilic substitution reaction with alkyl halides. For instance, bromobutane reacts with sodium hydrosulfide to give butanethiol.

02:17Structure and Nomenclature of Thiols and Sulfides
4.8K
Thiols and sulfides are sulfur analogs of alcohols and ethers, respectively, where the sulfur atom takes the place of the oxygen atom. Thus, thiols are generally represented as RSH, where R is an alkyl substituent and —SH is the functional group. On the other hand, in sulfides, the central sulfur atom is bonded to two hydrocarbon groups on either side. Depending upon the type of group, sulfides can be either symmetrical or asymmetrical. Both thiols and sulfides display a bent geometry,...

01:19Phase II Reactions: Sulfation and Conjugation with α-Amino Acids
246
Sulfation and α-amino acid conjugation are two critical biotransformation reactions in drug metabolism. Sulfation, a phase II biotransformation reaction, involves adding a polar sulfate group to a drug, enhancing its water solubility and promoting excretion. This process can either co-occur with or occur independently of glucuronidation. Nonmicrosomal sulfotransferase enzymes catalyze the process. The reaction involves 3'-phosphoadenosine-5'-phosphosulfate or PAPS coenzyme...
