Effects of Imazapyr on Spartina alterniflora and Soil Bacterial Communities in a Mangrove Wetland

Water (Switzerland), 2021
The invasion of Spartina alterniflora (S. alterniflora) has caused serious damage to coastal wetland ecosystems in China, especially the mangrove wetlands in South China. This study aimed to validate the effect of imazapyr on S.

Modelling the leaching of imazapyr in a railway embankment

Pest Management Science, 2006
Abstract The use of herbicides on railway tracks is known to present a risk to groundwater, but little is known of the mechanisms influencing leaching through the coarse material used to construct railway embankments. Therefore, in the present study, four different models based on the convection–dispersion equation (CDE) were compared

The Photocatalytic Degradation of Imazapyr

Monatshefte für Chemie - Chemical Monthly, 2007
The degradation of imazapyr, an imidazolinone herbicide, in aqueous solution has been investigated with TiO2 slurry as photocatalyst at 30°C under UV radiation. The depletion of imazapyr concentration in an aqueous suspension followed 1st order kinetic behavior.

Electrochemical oxidation of imazapyr with BDD electrode in titanium substrate

Chemosphere, 2014
In this work we have studied the treatment of imazapyr by electrochemical oxidation with boron-doped diamond anode. Electrochemical degradation experiments were performed in a one-compartment cell containing 0.45 L of commercial formulations of herbicide in the pH range 3.0-10.0 by applying a density current between 10 and 150 mA cm(-2) and in the ...

Response Surface Analysis of Control of Red Alder and Vine Maple with Glyphosate-Imazapyr and Triclopyr-Imazapyr

Western Journal of Applied Forestry, 1995
Abstract Quadratic response functions were demonstrated for predicting crown reduction of red alder (Alnus rubra) and vine maple (Acer circinatum) after application of the herbicides glyphosate and triclopyr in combinations with imazapyr.

Dissipation of imazapyr, flumetsulam and thifensulfuron in soil

Weed Research, 1997
SummaryThe degradation of imazapyr, flumetsulam and thifensulfuron applied at 500.40 and 30 g active ingredient (a.i.) ha‐1, respectively, to silt loam soil was studied under laboratory and field conditions. Herbicide residues were analysed by a lentil (Lens culinarits L.) bioassay.

Persistence and sorption of imazapyr in three Argentinean soils

Environmental Toxicology and Chemistry, 2013
Abstract   Imazapyr is a herbicide widely used for weed control in imidazolinone-tolerant sunflower. Imazapyr has a high potential for leaching into groundwater because it is highly water-soluble, persistent in soil, and only weakly sorbed by soils.

Enantioselective effects of herbicide imazapyr onArabidopsis thaliana

Journal of Environmental Science and Health, Part B, 2014
The enantioselective toxicity of chiral herbicides in the environment is of increasing concern. To investigate the enantioselective effects of the chiral herbicide imazapyr on target organisms, we exposed Arabidopsis thaliana to imazapyr enantiomers and racemate. The results show that imazapyr was enantioselectively toxic to A. thaliana.

The fate of imazapyr herbicide in the soil amended with carbon sorbents

Biomass Conversion and Biorefinery, 2021
Excessive application of agro-chemicals is a major factor in undesired environmental problems. Imidazolinone herbicides having high activity, leaching potential, and persistence are probable risks to ecosystems. Herbicides’ stabilization using biochar is an efficient and cheap strategy to protect the environment against their contaminations.

Comparability of imazapyr-resistant Arabidopsis created by transgenesis and mutagenesis

Transgenic Research, 2012
The Arabidopsis CSR1 gene codes for the enzyme acetohydroxyacid synthase (AHAS, EC 2.2.1.6), also known as acetolactate synthase, which catalyzes the first step in branched-chain amino acid biosynthesis. It is inhibited by several classes of herbicides, including the imidazolinone herbicides, such as imazapyr; however, a substitution mutation in csr1-2
