Biodegradation of nicosulfuron by a Talaromyces flavus LZM1
Bioresource Technology, 2013The fungal strain LZM1 was isolated from activated sludge and found to be capable of utilizing nicosulfuron as the sole nitrogen source for growth. Based on morphological and internal transcribed spacer evaluations, LZM1 was identified as a Talaromyces flavus strain. Under optimum conditions (pH 6.1, 29°C), T. flavus LZM1 degraded 100% of the initially

Dissipation of Nicosulfuron and Rimsulfuron in Surface Soil
Journal of Agricultural and Food Chemistry, 2002Field and soil fortification studies were conducted to evaluate the half-lives (DT(50)) of nicosulfuron and rimsulfuron in a Sequatchie silt loam surface soil. The dissipation of each herbicide was also evaluated with the two compounds applied simultaneously, which is a typical application method used in corn production.

Biodegradation of nicosulfuron by a novel Alcaligenes faecalis strain ZWS11
Journal of Environmental Sciences, 2015A bacterial strain ZWS11 was isolated from sulfonylurea herbicide-contaminated farmland soil and identified as a potential nicosulfuron-degrading bacterium. Based on morphological and physicochemical characterization of the bacterium and phylogenetic analysis of the 16S rRNA sequence, strain ZWS11 was identified as Alcaligenes faecalis.

Transport of Nicosulfuron in Soil Columns
Journal of Environmental Quality, 1999AbstractNicosulfuron (2‐[[[[(4,6‐dimethoxy‐2‐pyrimidinyl)amino]carbonyl]amino]sulfonyl]‐N,N‐dimethyl‐3‐pyridinecarboxamide) is a relatively new sulfonylurea promoted for weed control in corn (Zea mays L.). However, there are no published studies on its transport and mobility in soils.

Dynamics of Microbial Populations Activities After the Application of Nicosulfuron
2020When a pesticide gets into soil, it takes part in a number of physical, chemical and biological processes that depend not only on the compound itself, but a number of other factors such as physical, chemical, and biological characteristics of soil and climatic factors.

Effects of Atrazine and Nicosulfuron on Phytoplankton in Systems of Increasing Complexity
Archives of Environmental Contamination and Toxicology, 2001We have tested the sensitivity of phytoplankton to the herbicides atrazine and nicosulfuron in experiments conduced in increasingly complex systems, from single strain phytoplankton cultures (microplates) to mesocosms mimicking whole ecosystems.

Suppression of Annual Ryegrass in Corn with Nicosulfuron
Weed Technology, 2019AbstractField studies were conducted to determine the possible rate and timing of nicosulfuron to suppress annual ryegrass (ARG) seeded as a cover crop at the time of corn planting without affecting corn performance near Ridgetown, ON, Canada, in 2016 and 2017.

Studies on the interactions between nicosulfuron and degradation enzymes
Process Biochemistry, 2020Abstract The interactions between nicosulfuron and two degradation enzymes (vegetative catalase 1 and manganese ABC transporter) from the Bacillus subtilis YB1 strain were studied and molecular docking simulations and surface plasmon resonance (SPR) were used to research their specific interaction patterns and affinities.

Nicosulfuron: Alcoholysis, Chemical Hydrolysis, and Degradation on Various Minerals
Journal of Agricultural and Food Chemistry, 2002Alcoholysis (methanol or ethanol) and hydrolysis (pH ranging from 4 to 11) of the herbicide nicosulfuron at 30 degrees C principally involves the breakdown of the urea part of the molecule. A high yield of the corresponding carbamate was obtained along with aminopyrimidine during alcoholysis.
