Absorption and Translocation of Terbutryn and Propazine
Weed Science, 1973The 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’).

Immunoassay for Simazine and Atrazine with Low Cross-Reactivity for Propazine
Journal of Agricultural and Food Chemistry, 1996An 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.

Analytical Chemistry, 2001
An analytical methodology for the determination of triazines in environmental samples incorporating a molecularly imprinted solid-phase extraction (MISPE) process using a propazine-imprinted polymer was developed. Two different polymers were prepared using acetonitrile or toluene as porogen, and their optimum loading, washing, and elution conditions ...

Journal of Separation Science, 2009
AbstractThis paper describes the development of a sequential injection chromatography (SIC) procedure for separation and quantification of the herbicides simazine, atrazine, and propazine exploring the low backpressure of a 2.5 cm long monolithic C18 column.

Low-Volume Application of Propazine and Atrazine to Sorghum
Weed Science, 1972Over 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.

Determination of propazine by differential pulse polarography in micellar and emulsified media
Mikrochimica Acta, 1995An 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 ...

Analytical Letters, 2002
ABSTRACT The method for the determination of propazine, simazine, bromacil, hexazinone and metoxuron by zero order and derivative spectrophotometry has been worked out. In the three-component mixtures it was possible to analyse metoxuron and bromacil in the presence of simazine or propazine and hexazinone applying the first order derivative spectra ...

Cotton (Gossypium hirsutum) Tolerance to Propazine Applied Pre- and Postemergence
Weed Technology, 2011Field studies were conducted in 2007 and 2008 near Lubbock and Lamesa, TX, to determine the effects of propazine alone and in combination with glyphosate applied PRE and POST on cotton growth, yield, and lint value (fiber quality). Propazine at 0.56, 0.84, and 1.12 kg ai ha−1and in combination with glyphosate at 0.86 kg ae ha−1was applied PRE, early ...
