Ecotoxicity Thresholds for Ametryn, Diuron, Hexazinone and Simazine in Fresh and Marine Waters [PDF]

, 2018
Triazine and urea herbicides are two groups of photosystem II inhibiting herbicides frequently detected in surface, ground and marine waters. Yet, there are few water quality guidelines for herbicides. Ecotoxicity thresholds (ETs) for ametryn, hexazinone

Weed control with preemergence Ametryn in Arracacia xanthorrhiza

The Journal of Agriculture of the University of Puerto Rico, 2021
Two experiments were performed from 1985 to 1987 at Barranquitas in a Humatas soil to evaluate Ametryn (Evik 80 W) for preemergence control of weeds in Peruvian carrot or arradacha (Arracacia xanthorrhiza Banc). Five treatments were evaluated: Ametryn at 4.98, 8.97 and 17.94 kg ai/ha; a hand-weeded check (hoeing); and non-weeded check.

Susceptibility Among Populations of Crabgrass to Herbicides Inhibiting Photosystem II [PDF]

Planta Daninha, 2018
: Weed interference reduces the productive potential of crops. Among the control methods used, chemical ones occupy a major position. The repeated application of the same mechanism of action selects tolerant plants.

Oxidative Damage, Energy Imbalance, and Behavioral Disruptions in Girardia tigrina Exposed to Treated Sewage Effluents

Environmental Toxicology, EarlyView.
ABSTRACT This study assessed the ecotoxicological effects of treated sewage on the freshwater planarian Girardia tigrina, integrating biochemical, energetic, and behavioral biomarkers. Planarians were exposed for 48 h to different concentrations of treated sewage (12.5%, 25%, 50%, and 100%) and compared to controls using commercial water and water from

Dependent Articulation in the Global Pesticide Complex: Argentina's Agrochemical Industry After the Generics Market Revolution

Journal of Agrarian Change, EarlyView.
ABSTRACT Since the late 1990s, the pesticide industry has undergone a ‘generics revolution’ as the centre of production, and trade has shifted to the global South. China and India have become major producers, capturing Latin American markets from Northern multinationals. As a major pesticide user and a key node in global supply chains, Argentina offers
