Dissipation Kinetics and Degradation Mechanism of Amicarbazone in Soil Revealed by a Reliable LC-MS/MS Method

Environmental Science and Pollution Research, 2015
A sensitive and reliable analytical method was developed for simultaneous determination of amicarbazone (AMZ) and its two major metabolites including desamino amicarbazone (DA) and isopropyl-2-hydroxy-DA-amicarbazone (Ipr-2-OH-DA-AMZ) in soil for the first time.

Seashore Paspalum Tolerance to Amicarbazone at Various Seasonal Application Timings

Weed Technology, 2015
Turfgrass injury from triazines has limited the use of photosystem II (PS II) inhibitors for weed control in seashore paspalum. Amicarbazone is a new PS II inhibitor with potential safety in seashore paspalum, but the effects of application timing on turf tolerance has received limited investigation.

Flazasulfuron Tank Mixtures with Amicarbazone for Annual Bluegrass Control in Seashore Paspalum

Applied Turfgrass Science, 2014
Flazasulfuron may be safely applied to actively growing seashore paspalum (Paspalum vaginatum Sw.), but applications for annual bluegrass control in late winter or spring could be injurious. A 3‐year field experiment was conducted to evaluate tank mixtures of flazasulfuron with amicarbazone at turf dormancy or partial greenup to determine if ...

Amicarbazone degradation promoted by ZVI-activated persulfate: study of relevant variables for practical application

Environmental Science and Pollution Research, 2017
Alarming amounts of organic pollutants are being detected in waterbodies due to their ineffective removal by conventional treatment techniques, which warn of the urgent need of developing new technologies for their remediation. In this context, advanced oxidation processes (AOPs), especially those based on Fenton reactions, have proved to be suitable ...

Amicarbazone and Other Group 5 Herbicide Behavior in Soil Under Field and Laboratory Conditions

Weed Technology
Abstract Amicarbazone, atrazine, and metribuzin behavior was examined in a field setting in Tennessee and in a laboratory setting using soils collected from Illinois and Tennessee. Fields planted to corn were sampled from 0 to 8 cm depth, and the samples were analyzed using methanolic extraction followed by tandem mass spectrometry analysis to ...

Amicarbazone degradation by UVA-activated persulfate in the presence of hydrogen peroxide or Fe 2+

Catalysis Today, 2017
Abstract In recent years, persulfate (PS)-driven oxidation has been extensively studied as an efficient remediation technique for in situ chemical oxidation of contaminated sites. Among other ways, PS can be activated by UV radiation but most UV sources applied in PS activation studies are in the UVC range (λex ∼ 254 nm), whilst the use of UVA has ...

Relative Lateral Movement in Surface Soil of Amicarbazone and Indaziflam Compared With Other Preemergence Herbicides for Turfgrass

Weed Technology, 2016
Amicarbazone and indaziflam are relatively new herbicides that provide effective control of important weed species in turfgrass. A concern for golf course superintendents and turfgrass managers is the lack of information about runoff risk of these two herbicides, which is a limitation to their proper and safe use.

Rooting Depth, Soil Type, and Application Rate Effects on Creeping Bentgrass Injury with Amicarbazone and Methiozolin

Crop Science, 2013
ABSTRACTAmicarbazone and methiozolin are herbicides with efficacy for annual bluegrass (Poa annua L.) control in creeping bentgrass (Agrostis stolonifera L.). Research was conducted to determine the effects of rooting depth and soil type on creeping bentgrass injury following amicarbazone and methiozolin applications. ‘Penncross’ creeping bentgrass was
