Hexazinone and simazine dissipation in forestry field nurseries [PDF]

Chemosphere, 2004
Hexazinone and simazine field dissipation was studied in two different soils from Spain (Toledo and Burgos), devoted to forest nurseries for Pinus nigra. Laboratory experiments (adsorption-desorption isotherms, leaching experiment and degradation study) were carried out to determine possible mechanisms of dissipation. Higher adsorption was observed for

Weed control and weed biomass influenced first cutting forage accumulation and nutritive value of spring‐seeded alfalfa

Agronomy Journal, Volume 115, Issue 6, Page 2979-2989, November/December 2023., 2023
Abstract Weeds can influence the economics of alfalfa (Medicago sativa L.) production by reducing forage yield and nutritive value or by contaminating hay. Field studies were conducted in Idaho in 2021 and 2022 to evaluate the effect of weed control treatments on alfalfa forage accumulation, weed biomass, and nutritive value.

Prioritizing Pesticides of Potential Concern and Identifying Potential Mixture Effects in Great Lakes Tributaries Using Passive Samplers

Environmental Toxicology and Chemistry, Volume 42, Issue 2, Page 340-366, February 2023., 2023
Abstract To help meet the objectives of the Great Lakes Restoration Initiative with regard to increasing knowledge about toxic substances, 223 pesticides and pesticide transformation products were monitored in 15 Great Lakes tributaries using polar organic chemical integrative samplers.

Short‐term effects of organic matter and compaction manipulations on soil temperature, moisture, and soil respiration for 2 years in the Oregon Cascades

Soil Science Society of America Journal, Volume 87, Issue 1, Page 156-171, January/February 2023., 2023
Abstract Understanding the factors controlling nutrient dynamics can help guide forest management plans to promote their long‐term productivity. We used experimental treatments with three levels of biomass removals and two levels of compaction to monitor the impacts to soil biophysical characteristics in an intensively managed forest. Soil temperature,

Effects of straw decomposition degree on leaching and weed control efficacy of tebuthiuron and hexazinone in green sugarcane harvesting [PDF]

Planta Daninha, 2014
Green sugarcane harvesting may promote great changes in the dynamics of herbicides in the environment. Our goal was to evaluate the influence of straw decomposition degree on leaching and weed (Ipomoea grandifolia) control efficacy by (14C) tebuthiuron ...

Rapid Screening of 352 Pesticide Residues in Chrysanthemum Flower by Gas Chromatography Coupled to Quadrupole‐Orbitrap Mass Spectrometry with Sin‐QuEChERS Nanocolumn Extraction

Journal of Analytical Methods in Chemistry, Volume 2022, Issue 1, 2022., 2022
To analyze pesticide residues, GC coupled with quadrupole‐Orbitrap MS (GC‐Orbitrap‐MS) has become a powerful tool because of its unique characteristics of accurate mass full‐spectrum acquisition, high resolution, fast acquisition rates, and overcoming matrix interference. This paper presents an efficiency evaluation of GC‐Orbitrap‐MS for identification

Removal of Matrix Interferences by Nano‐MgO and Co‐Adsorbents for Accurate Multi‐Pesticide Residue Analysis in the Chinese Medicinal Herb, Paeoniae Radix Alba

Journal of Analytical Methods in Chemistry, Volume 2021, Issue 1, 2021., 2021
A simple, accurate, and high‐throughput analytical method was developed to detect 123 pesticide residues in Chinese medicinal herb Paeoniae Radix Alba (PRA) by introducing nano‐MgO as a highly efficient purification material based on quick, easy, cheap, effective, rugged, and safe (QuEChERS) design concept. Various PRA samples were extracted using 8 mL

Chronic toxicity, reproductive, and teratogenic studies of hexazinone

Fundamental and Applied Toxicology, 1984
Hexazinone [3-cyclohexyl-6-(dimethylamino)-1-methyl-1,3,5-triazine 2,4(1H,3H)-dione; CAS 51235-04-2] was tested for oral toxicity in rats (both 90-day and 2-year feeding studies), mice (8-week and 2-year feeding studies), and dogs (90-day feeding study).
