  Background and Objective: Atrazine is one of the most important herbicides in the world and Iran, which has high stability and is likely to contaminate runoff and groundwater resources. The aim of this experiment was to determine the most sensitive of the eight plant species to atrazine and to measure the leaching front of this herbicide.Material and Methodology: The first experiment did in order to sensitivity assessment of eight plant species (Canola, Soybean, Ryegrass, Wild Oat, Wheat, Canarygrass, Redroot Pigweed, and Corn) to simulated atrazine residues by GR50 index (the required dose of herbicide to reduce plant growth by 50% ) at 2019. The second experiment was conducted to determine leaching front of atrazine. Levels of atrazine treatments were: control, usual dose (1.25 kg.h-1) and high dose (2.5 kg.h-1). The treatments were injected into soil columns in 32 cm height PVC pipes and after three days, all 2 cm pieces of soil columns were exposed to bioassay and chemical analysis, simultaneously.In the first experiment probit regression analysis was used to identify the most atrazine-sensitive species and in second experiment with completely randomized basic design the data were investigated by regression analysis.Findings: First experiment showed that canola was more susceptible to atrazine compared to other species. Evaluation of canola seedling weight profile and atrazine concentration simultaneously at different depths of soil showed that atrazine penetrated to 10 cm depth.Discussion and Conclusion: It seems that atrazine accumulation to 10 cm depth is related to higher organic matter and clay content. Due to the fact that the maximum weed seed bank was located in the surface layers of the soil, application of atrazine herbicide in this field can increase the efficiency of weed control.

  A rapid, precise and sensitive method derivate from homogeneous liquid-liquid microextraction method namely in situ solvent formation microextraction using ionic liquids as green solvent and extractant phase to the analysis of trace amount of Atrazine in real water samples has been used. Here, the extractant phase, is a solvent from ionic liquids family namely 1-ethyl-3-methylimidazolium chloride [Emim][Cl] that is miscible in water and after interaction with analyte and adding of counter ion of Hexafluorophosphate [PF6-], convert to the immiscible ionic liquid of 1-ethyl-3-methylimidazolium hexafluorophosphate [Emim][PF6]. Initially and during extraction of analyte from aqueous phase, because to absence any common boundary between aqueous and organic phase, the extraction efficiency will be maximum. After extraction process, to separation of two phases apart and determination amount of extracted analyte, due to formation of immiscible ionic liquid in water, separation of phases it become possible. Effect of different analytical parameters on extraction efficiency such as sample solution pH containing analyte, ionic liquid amount, extraction time and counter ion amount were evaluated and optimum amount were determined. Characteristics of the method such as limit of detection (LOD), limit of quantification (LOQ), relative standard deviation (RSD) and linear dynamic range (LDR) were 1.78 µgL-1, 6.1 µgL-1, 12.3 ppt and 5-1500 µgL-1, respectively. The method was used successfully to extraction and determination of Atrazine in several real water samples. Determination of Atrazine amount was carried out by sensitive high performance liquid chromatography. Manuscript profile

  To evaluate some herbicides efficiency for broomcorn’s weeds chemical management under farm conditions, an experiment was carried out in randomized completely block design with four replications in Achachi village of Miyaneh region. The herbicides were Atrazine as pre-plant incorporated with soil + alachlor as pre-emergence, atrazine as pre-emergence + eradicane as pre-plant incorporated with soil, 2,4-D+MCPA as post-emergence + hand weeding, foramsulfuron as post-emergence, nicosulfuron as post-emergence, alachlor as pre-emergence, nicosulfuron as post-emergence, alachlor as pre-emergence + 2,4-D MCPA as pre-emergence + hand weeding, alachlor as pre-emergence, atrazine as pre-plant, and hand weeding was considered as control. Atrazin and 2,4-D+MCPA + hand weeding of narrow-leaf weeds were not differet significantly with control. Results revealed that application of atrazin and 2,4-D MPCA + narrow-leaf hand weeding had no significant difference with hand weeding in weed control and side-effect on the crop. Despite positive effect on weed controlling, atrazine + alachlor, atrazine + eradican, alachlor, eradican and 2,4-D were phytotoxic on broomcorn. The pre-plant application method was better than pre- and post-emergence methods. Based on the results, individual application of herbicides tested was more effective than their mixing.

  To study the effects of anti-transpiration spraying and irrigation cutting off in different growth stages on yield and yield components of sunflower hybrid of Farrokhas second crop at Miyaneh region, an experiment was conducted at the Research Station of Faculty of Agriculture Islamic Azad University (Miyaneh Branch) during 2013 cropping season. The experiment was in randomized complete block design with three replications. The experiment factors were anti-transpiration spraying with paraffin, atrazine, and phenyl mercuric acetate (PMA), along with irrigation cutting off in inflorescence full blooming and seed filling stages. The traits of seed yield, , biological yield, harvest index, number of seeds per head, seed weight, oil percent, leaf dry weight, head diameter was measured at the end of experiment. There were significant difference of interaction between irrigation cutting off and anti- transpiration application on seed weight, head diameter at 1% and oil percentage at 5% probability level. PMA application caused the highest seed yield and head dry weight. Irrigation cutting off in inflorescence emergence stage along with atrazine implementation led to the highest oil percentage, head diameter and seed number per head. Regarding the results, anti-transpiration application and longer water storage could be one of the suitable methods for high production of sunflower in arid and semi-arid areas. Manuscript profile
