Determination of Chloro-s-Triazines including Didealkylatrazine using Solid Phase Extraction Coupled with Gas Chromatography/Mass Spectrometry

open access: yes, 2004
Chloro-s-triazines are a class of compounds comprising atrazine, simazine, propazine, cyanazine and their chlorinated metabolites. The US Environmental Protection Agency (EPA) has determined that selected chloro-s-triazines – atrazine, simazine ...

Tolerance of Kleingrass to Herbicides

open access: yes, 1979
Herbicides propazine, 2,4-D, dicamba, picloram, tebuthiuron, and hexazinone were applied at rates of 0.14 to 2.24 kg/ha pre- and postemergence to greenhouse-grown kleingrass plants. Kleingrass was tolerant to premergence sprays up to and including 1.2 kg/

Cytological and Morphological Effects of Atrazine and Propazine Application on Grain Sorghum.

open access: yesCYTOLOGIA, 1996
Effectiveness on weed control and injury on sorghum plants were compared for herbicides atrazine and propazine which were applied at four different rates, 0.56, 1.1, 2.2 and 4.5kg/ha. It was found that both herbicides at rates above 2.2kg/ha reduced plant height but propazine caused less injury than atrazine.

Rapid Screening of 300 Pesticide Residues in Commercially Available Vegetable‐, Fruit‐, and Cereal‐Based Baby Foods by Using Amino‐Functionalized Multiwalled Carbon Nanotubes with QuEChERS and Gas Chromatography‐Electrostatic Field Orbitrap High‐Resolution Mass Spectrometry

open access: yesJournal of Food Quality, Volume 2024, Issue 1, 2024.
A new method for screening 300 pesticide residues in fruit‐, vegetable‐, and cereal‐based baby foods by an improved QuEChERS purification method based on amino‐functionalized multiwalled carbon nanotubes (NH2‐MWCNTs) combined with gas chromatography‐electrostatic field orbitrap high‐resolution mass spectrometry (Orbitrap GC‐MS) was developed.

Toxicity Assessment of Atrazine and Related Triazine Compounds in the Microtox Assay, and Computational Modeling for Their Structure-Activity Relationship

open access: yes, 2000
The triazines are a group of chemically similar herbicides including atrazine, cyanazine, and propazine, primarily used to control broadleaf weeds. About 64 to 80 million lbs of atrazine alone are used each year in the United States, making it one of the

Propazine Has Little Effect on Growth of Several Containerized Woody Plant Species [PDF]

open access: yesHortTechnology, 1999
Woody plant species were treated in 1995 and 1996 with 0, 1, 2, or 4 lb/acre (0, 1.1, 2.3, or 4.5 kg·ha -1 ) propazine (a.i.). Species studied in 1995 included rose-of-sharon ( Hibiscus syriacus L. `Double Purple'), japanese boxwood (

New insights into the interactions between cork chemical components and pesticides. The contribution of π-π interactions, hydrogen bonding and hydrophobic effect

open access: yes, 2015
The role of chemical components of cork in the sorption of several pesticides has been investigated. For this purpose raw cork and three cork extracted fractions (i.e.
