Electrochemical reduction of propazine: NMR evidence for dechlorination and reduction of the triazine ring

Journal of Electroanalytical Chemistry, 2010
Abstract Propazine (2-chloro-4,6-diisopropylamino-1,3,5-triazine) is a triazine herbicide used to control broadleaf weeds and annual grasses during the production of milo grain sorghum. This compound provides post-emergent protection by interfering with photosynthetic electron transport of target weeds.

Determination of propazine by differential pulse polarography in micellar and emulsified media

Mikrochimica Acta, 1995
An electroanalytical study of the herbicide propazine's reduction process in micellar solutions and oil-in-water emulsions is reported. The anionic surfactant sodium pentanesulphonate was chosen as the most suitable. The differential pulse polarograms of micellar solutions had two reduction peaks below pH 2.0, whereas only one peak was obtained above ...

Mechanism of action of propazine, a compound of the symmetrical triazine group, in vivo

Bulletin of Experimental Biology and Medicine, 1972
Der iva t ives of the s y m m e t r i c a l t r i az ines can act as folic acid antagonis ts [19]. The abili ty of such antagonis ts to induce " thymine s tarvat ion" has been descr ibed [12]. A typical f ea tu re of folic acid def ic iency in the body is a d is turbance of nucleic acid me tabo l i sm [18].

Characterisation and quality assessment of binding sites on a propazine-imprinted polymer prepared by precipitation polymerisation

Journal of Chromatography B: Analytical Technologies in the Biomedical and Life Sciences, 2004
In this paper, the Langmuir-Freundlich isotherm (LF) is used to characterise a propazine-imprinted polymer obtained by precipitation polymerisation (MIP-P). Different rebinding studies were carried out allowing to explain the different interactions taking place between the molecularly imprinted polymer and six triazinic herbicides (desisopropylatrazine,

Absorption and Translocation of Terbutryn and Propazine

Weed Science, 1973
The absorption and translocation patterns of terbutryn [2-(tert-butylamino)-4-(ethylamino)-6-(methylthio)-s-triazine] and propazine [2-chloro-4,6-bis(isopropylamino)-s-triazine] were determined in wheat (Triticum vulgareVill. ‘Kaw’) and sorghum (Sorghum bicolorL. ‘RS 612’).

Low-Volume Application of Propazine and Atrazine to Sorghum

Weed Science, 1972
Over a 3-year period, pigweed (Amaranthus sp.) was successfully controlled in grain sorghum (Sorghum bicolor (L.) Moench) with preemergence aerial application of 2-chloro-4, 6-bis(isopropylamino)-s-triazine (propazine) and postemergence application of 2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine (atrazine) in 4.7 to 47 L/ha of various carriers.

Immunoassay for Simazine and Atrazine with Low Cross-Reactivity for Propazine

Journal of Agricultural and Food Chemistry, 1996
An antibody for simazine and atrazine has been developed that exhibits low cross-reactivity to propazine relative to most atrazine antibodies heretofore evaluated. The cross-reactivities obtained in an enzyme-linked immunosorbent assay were 100 ( 4% for simazine, 76 ( 9% for atrazine, and 12.6 ( 1.3% for propazine.

Montmorillonite as an adsorbent for extraction and concentration of atrazine, propazine, deethylatrazine, deisopropylatrazine and hydroxyatrazine

Analytica Chimica Acta, 2006
Adsorption properties of the clay mineral montmorillonite in the potassium homoionic form (KMT) was investigated to achieve the extraction and concentration of the herbicides atrazine (AT) and propazine (PROP), as well as the main degradation products of atrazine, namely deethylatrazine (DEA), deisopropylatrazine (DIA) and hydroxyatrazine (ATOH).
