Despite the widespread adoption and use of herbicides, weeds still persist in agricultural and horticultural systems. Weeds can escape chemical control for numerous reasons, including: incorrect herbicide or rate selection, improper sprayer calibration, clogged nozzles or otherwise malfunctioning equipment,...

Mechanism of metamifop inhibition of the carboxyltransferase domain of acetyl-coenzyme A carboxylase in Echinochloa crus-galli.

Scientific reports

Xia X, Tang W, He S, Kang J, Ma H, Li J.
PMID: 27666674
Sci Rep. 2016 Sep 26;6:34066. doi: 10.1038/srep34066.

Acetyl-coenzyme A carboxylase (ACCase) plays crucial roles in fatty acid metabolism and is an attractive target for herbicide discovery. Metamifop is a novel ACCase-inhibiting herbicide that can be applied to control sensitive weeds in paddy fields. In this study,...

In vitro propagation and analysis of secondary metabolites in Glossogyne tenuifolia (Hsiang-Ju) - a medicinal plant native to Taiwan.

Botanical studies

Chen CC, Chang HC, Kuo CL, Agrawal DC, Wu CR, Tsay HS.
PMID: 28510942
Bot Stud. 2014 Dec;55(1):45. doi: 10.1186/s40529-014-0045-7. Epub 2014 Jun 24.

BACKGROUND: Glossogyne tenuifolia Cassini (Hsiang-Ju in Chinese) is a perennial herb native to Penghu Islands, Taiwan. The herb is a traditional anti-pyretic and hepatoprotective used in Chinese medicine. Several studies on G. tenuifolia have demonstrated its pharmacological values of...

3,4-Dichloroaniline revisited: A study on the fate of the priority pollutant in a sediment-water system derived from a rice growing region in Italy.

The Science of the total environment

Yuan Y, Zhang P, Schäffer A, Schmidt B.
PMID: 27668853
Sci Total Environ. 2017 Jan 01;574:1012-1020. doi: 10.1016/j.scitotenv.2016.09.099. Epub 2016 Oct 14.

As ultimate sink for xenobiotics released into the environment, sediments play an important role concerning the evaluation of the fate of foreign compounds. 3,4-Dichloroaniline (3,4-DCA) is a degradation product of herbicide propanil and some urea herbicides. Propanil was extensively...

Assessment of the Environmental Fate of the Herbicides Flufenacet and Metazachlor with the SWAT Model.

Journal of environmental quality

PMID: 25602542
J Environ Qual. 2014 Jan;43(1):75-85. doi: 10.2134/jeq2011.0382.

This study aims to assess the environmental fate of the commonly used herbicides flufenacet and metazachlor in the Northern German Lowlands with the ecohydrological Soil and Water Assessment Tool (SWAT model) and to test the sensitivity of pesticide-related input...

Separation and concentration of sulfonylurea herbicides in milk by ionic-liquid-based foam flotation solid-phase extraction.

Journal of separation science

Zhang L, Cao B, Yao D, Yu R, Yu C, Zhang H, Yu A.
PMID: 25727190
J Sep Sci. 2015 May;38(10):1733-40. doi: 10.1002/jssc.201401344. Epub 2015 Apr 02.

The ultrasound-assisted ionic liquid foam flotation solid-phase extraction of sulfonylurea herbicides in milk was developed and validated. The proteins and lipids were isolated from the sample matrix by adding salt and adjusting the pH value. The target analytes eluted...

Molecular Basis for Resistance Against Phosphonate Antibiotics and Herbicides.

Research in recent years have illuminated data on the mechanisms and targets of phosphonic acid antibiotics and herbicides, including fosfomycin, glyphosate, fosmidomycin and FR900098. Here we review the current state of knowledge of the structural and biochemical characterization of...

Development of nanoformulation approaches for the control of weeds.

The Science of the total environment

Kumar S, Bhanjana G, Sharma A, Dilbaghi N, Sidhu MC, Kim KH.
PMID: 28236485
Sci Total Environ. 2017 May 15;586:1272-1278. doi: 10.1016/j.scitotenv.2017.02.138. Epub 2017 Feb 22.

The nanoformulation of pesticides has the potential to increase food productivity, while resolving the drawbacks of conventional agrochemicals, which have negative environmental impacts. In this study, herbicide (metsulfuron methyl)-loaded pectin (polysaccharide) nanoparticles were synthesized and evaluated for herbicidal activity...

iMAR: An Interactive Web-Based Application for Mapping Herbicide Resistant Weeds.

PloS one
