Efficacy and Nontarget Effects of Glyphosate and Two Organic Herbicides for Invasive Woody Vine Control

Natural areas journal, 2020
Mat-forming vines constitute half of invasive plant cover in eastern United States forests. Although glyphosate provides effective control, it has been garnering waning public acceptance due to its potential for harming human health and nontarget ...

Reproductive toxicity due to herbicide exposure in freshwater organisms

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2021
Excessively used pesticides in agricultural areas are spilled into aquatic environments, wherein they are suspended or sedimented. Owing to climate change, herbicides are the fastest growing sector of the pesticide industry and are detected in surface water, groundwater, and sediments near agricultural areas. In freshwater, organisms, including mussels,

Herbicide toxicity to fish-food organisms

Environmental Pollution Series A, Ecological and Biological, 1982
Abstract The toxic effects of 2,4-D, Dalapon and Tafazine at varying levels on Brachionus calyciflorus, Daphnia lumholtzi, Mesocyclops leuckarti and Heliodiaptomus viduus were investigated. Complete mortality was observed within 31 h among B. calyciflorus exposed to 5·0 ppm 2,4-D. Higher concentrations of 2,4-D were lethal to D. lumholtzi, the entire

Herbicide Roundup shows toxic effects in nontarget organism Drosophila

Archives of Insect Biochemistry and Physiology, 2022
AbstractGlyphosate‐based herbicide Roundup, as the most employed herbicide used for multiple purposes in agriculture, adversely affects nontarget organisms. We tested the effects of Roundup applied at larval and adult stages. Roundup caused developmental delay and increased larvae mortality.

Surface Ionization Organic Mass Spectrometry ofs-Triazine Herbicides

Journal of Mass Spectrometry, 1997
Surface ionization organic mass spectrometry (SIOMS) was applied to some s-triazine herbicides (simazine, atrazine, simetryne, ametryne and prometryne) by using quadrupole mass spectrometry in which the thermal ion source has a rhenium oxide emitter.

Improved herbicide efficacy for organically grown vegetables

Organic Agriculture, 2015
Natural weed control alternatives that are currently approved for organic crop production are mostly nonselective essential oils used as postemergence, burn-down products. Their low efficacy requires multiple applications of high volumes to achieve good weed control.

Novel Formulations of an Organic Acid Herbicide

Journal of ASTM International, 2011
Abstract Herbicides sold commercially to producers of organic crops have low specific activity. The potential exists to increase the herbicidal activity of the more active candidate herbicides with appropriate and acceptable adjuvants and emulsifiers.

Control of Nutsedge with Organic Arsenical Herbicides

Weed Science, 1971
Nonradioactive and14C-labeled arsenical herbicides were applied to foliage of purple nutsedge (Cyperus rotundusL.) and yellow nutsedge (Cyperus esculentusL.) grown under greenhouse and growth chamber conditions. Disodium methanearsonate (DSMA) controlled purple nutsedge better at 20 and 29 C than at 13 C.

Photodegradation of new herbicide HW-02 in organic solvents

Journal of Environmental Sciences, 2010
HW-02 is a new organophosphates herbicide which is discovered and developed in China. The kinetics and mechanism of HW-02 photodegradation in the organic solvents were studied at 25 degrees C under the irradiation of ultraviolet light. The results showed that photochemical reaction of HW-02 in organic solvents such as n-hexane, methanol, dimethyl ...
