Characterization of Nicosulfuron Availability in Aged Soils
Journal of Agricultural and Food Chemistry, 2008Sorption-desorption interactions of pesticides with soil determine their availability for transport, plant uptake, and microbial degradation. These interactions are affected by the physical-chemical properties of the pesticide and soil, and for some pesticides, their residence time in the soil.

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

Surfactants and Oil Adjuvants with Nicosulfuron
Weed Technology, 1995Nicosulfuron is used with surfactant or oil adjuvant to enhance postemergence efficacy. Yellow foxtail fresh weight reduction from nicosulfuron varied from 10 to 92% depending upon surfactant in greenhouse experiments. Oil adjuvants differed in enhancement of nicosulfuron phytotoxicity to yellow foxtail or large crabgrass with methylated canola oil ...

Salts and Surfactants Influence Nicosulfuron Activity
Weed Technology, 1995Experiments were conducted in the greenhouse to determine nicosulfuron activity on large crabgrass as influenced by surfactant, ammonium salt adjuvants, and various calcium, sodium, and magnesium salts in the spray carrier. Nicosulfuron activity varied with surfactant.

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.

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.

The action mode of sulfonylurea herbicides is the inhibition of the acetohydroxyacid synthase (AHAS) required for the biosynthesis of amino acids valine and isoleucine in plants. However, this enzyme is also present in a range of non-targeted organisms, among which soil microorganisms are known for their pivotal role in ecosystem functioning.

Sweet corn tolerance to nicosulfuron as affected by interactions between nicosulfuron applied postemergence (POST), sweet corn hybrid, and rootworm insecticide applied at planting was determined in 1992 and 1993 field experiments. Sweet corn vigor was reduced as nicosulfuron rate increased from 35 to 140 g ai/ha. Sweet corn vigor was reduced 4% more by
