Article history: Received on: 21/11/2015 Revised on: 07/12/2015 Accepted on: 26/12/2015 Available online: 09/01/2016 The toxicological effects of herbicide Pretilachlor on photosynthesis, respiration and nitrogen assimilation of the unicellular cyanobacterium Synechocystis sp. PUPCCC 64 has been studied. Treatment of the test organism with Pretilachlor (10, 15 and 20 mg L -1 ) negatively affect...

The influence of individual or combined treatments of the chloroacetanilide herbicide preti­ lachlor and the safener fenclorim on glutathione content and the activity of glutathione reduc­ tase (GR, EC 1.6.4.2) and glutathione-S-transferase (GST, EC 2.5.1.18) of rice (O ryza sativa L., var. Lamont) was investigated in a time-course study including 0, 12, 24, 48, and 72 h peri­ ods after treatme...

Background: The presence of pesticides is very prevalent in surface waters of Iran. These toxic substances may accumulate in the food chain and cause serious ecological and health problems. The aim of this study was to determine the acute toxicity of glyphosate, deltamethrin and pretilachlor as potential dangerous organic pesticides to assess lethal effects of these chemicals agents to the Gupp...

No validated models in Europe are capable of simulating the environmental fate of pesticides under the specific conditions of rice fields. Rice water quality--vadose zone flow and transport (RICEWQ-VADOFT) is a model developed from the coupling of a surface runoff model (RICEWQ) and a vadose zone flow and transport model (VADOFT) for determining predicted environmental concentrations in paddy w...

Experiments were carried out in the field and laboratory during 2001-02 to study the persistence of three herbicides, namely butachlor, pretilachlor (Rifit) and 2,4-D in a rice – rice system and the effect of their residues on soil micro flora. Irrespective of the seasons and treatments, all the three herbicides dissipated quickly from soil and no residues were detected at the time of harvest. ...

Background: The presence of pesticide due to the huge demand for agricultural purposes is very prevalent in surface waters of Iran. These pesticides could finally accumulate in aquatic ecosystems and have been proved to have toxic effects on aquatic animals. The aim of this study was to assess the acute toxicity of Diazinon, Deltamethrin, Butachlor and Pretilachlor on Zebra Cichlid (Cryptoheros...

A comparative test was undertaken in order to identify the potential of existing mathematical models, including the rice water quality (RICEWQ) 1.6.4v model, the pesticide concentration in paddy field (PCPF-1) model and the surface water and groundwater (SWAGW) model, for calculating pesticide dissipation and exposure in rice paddies in Europe. Previous versions of RICEWQ and PCPF-1 models had ...
