It is the most widely used herbicide in the world, and the third most commonly used in North America.[1] 2,4-D is also an important synthetic auxin, often used in laboratories for plant research and as a supplement in plant cell culture media such as MS medium. History 2,4-D was developed during World War II by a British team at Rothamsted Experimental Station, under the leadership of Judah Hirsch Quastel, aiming to increase crop yields for a nation at war.[citation needed] When it was commercially released in 1946, it became the first successful selective herbicide and allowed for greatly enhanced weed control in wheat, maize (corn), rice, and similar cereal grass crop, because it only kills dicots, leaving behind monocots. Mechanism of herbicide action 2,4-D is a synthetic auxin, which is a class of plant growth regulators. -

Abstract: Dichlorvos (O,O-dimethyl O-(2,2-dichlorovinyl)phosphate, DDVP) is a widely acknowl- edged broad-spectrum organophosphorus insecticide and acaracide. This pesticide has been used for more than four decades and is still in strong demand in many developing countries. Extensive application of DDVP in agriculture has caused severe hazardous impacts on living systems. The International Agency for Research on Cancer of the World Health Organization considered DDVP among the list of 2B carcinogens, which means a certain extent of cancer risk. Hence, removing DDVP from the environment has attracted worldwide attention. Many studies have tested the removal of DDVP using different kinds of physicochemical methods including gas phase surface discharge plasma, physical adsorption, hydrodynamic cavitation, and nanoparticles. -
12.18 Carbofuran Carbofuran (CAS No
12. CHEMICAL FACT SHEETS WHO (2003) Cadmium in drinking-water. Background document for preparation of WHO Guidelines for drinking-water quality. Geneva, World Health Organization (WHO/SDE/WSH/03.04/80). 12.18 Carbofuran Carbofuran (CAS No. 1563-66-2) is used worldwide as a pesticide for many crops. Residues in treated crops are generally very low or not detectable. The physical and chemical properties of carbofuran and the few data on occurrence indicate that drink- ing-water from both groundwater and surface water sources is potentially the major route of exposure. Guideline value 0.007 mg/litre Occurrence Has been detected in surface water, groundwater and drinking-water, generally at levels of a few micrograms per litre or lower; highest concentration (30 mg/litre) measured in groundwater ADI 0.002 mg/kg of body weight based on a NOAEL of 0.22 mg/kg of body weight per day for acute (reversible) effects in dogs in a short-term (4- week) study conducted as an adjunct to a 13-week study in which inhibition of erythrocyte acetylcholinesterase activity was observed, and using an uncertainty factor of 100 Limit of detection 0.1 mg/litre by GC with a nitrogen–phosphorus detector; 0.9 mg/litre by reverse-phase HPLC with a fluorescence detector Treatment achievability 1 mg/litre should be achievable using GAC Guideline derivation • allocation to water 10% of ADI • weight 60-kg adult • consumption 2 litres/day Additional comments Use of a 4-week study was considered appropriate because the NOAEL is based on a reversible acute effect; the NOAEL will also be protective for chronic effects. -

Additive Interactions of Some Reduced-Risk Biocides and Two
www.nature.com/scientificreports OPEN Additive interactions of some reduced‑risk biocides and two entomopathogenic nematodes suggest implications for integrated control of Spodoptera litura (Lepidoptera: Noctuidae) Rashad Rasool Khan 1,2*, Muhammad Arshad 1*, Asad Aslam 3 & Muhammad Arshad 4 Higher volumes of conventional and novel chemical insecticides are applied by farmers to control resistant strains of armyworm (Spodoperta litura) in Pakistan without knowing their risks to the environment and to public health. Ten reduced‑risk insecticides were tested for their compatibility with two entomopathogenic nematodes (EPNs); Heterorhabditis indica and Steinernema carpocapsae rd against S. litura. The insecticide emamectin benzoate was highly toxic (LC50 = 2.97 mg/l) against 3 instar S. litura larvae when applied alone whereas, novaluron and methoxyfenozide were the least toxic (LC50 = 29.56 mg/l and 21.06 mg/l), respectively. All the insecticides proved harmless against the two EPNs even 96 h after treatment. Indoxacarb, fubendiamide and spinetoram produced the greatest mortalities (72–76%) of S. litura larvae after 72 h when applied in mixtures with H. indica. Lowest mortalities (44.00 ± 3.74% and 48.00 ± 2.89) were observed for mixtures of H. indica with methoxyfenozide and chlorfenapyr, respectively. The positive control treatments with both EPNs (S. carpocapsae and H. indica) produced > 50% mortality 96 h after treatment. For insecticide mixtures with S. carpocapsae, only indoxacarb produced 90% mortality of larvae, whereas, indoxacarb, fubendiamide, emamectin benzoate, and spinetoram produced 90–92% mortality of larvae when applied in mixtures with H. indica. Additive interactions (Chi‑square < 3.84) of EPN mixtures with reduced volumes of reduced‑risk insecticides suggest opportunities to develop more environmentally favorable pest management programs for S. -

Method 8141B
METHOD 8141B ORGANOPHOSPHORUS COMPOUNDS BY GAS CHROMATOGRAPHY 1.0 SCOPE AND APPLICATION 1.1 This method provides procedures for the gas chromatographic (GC) determination of organophosphorus (OP) compounds. The compounds listed in the table below can be determined by GC using capillary columns with a flame photometric detector (FPD) or a nitrogen-phosphorus detector (NPD). Triazine herbicides can also be determined with this method when the NPD is used. Although performance data are presented for each of the listed chemicals, it is unlikely that all of them could be determined in a single analysis. This limitation results because the chemical and chromatographic behavior of many of these chemicals can result in co-elution. The analyst must select columns, detectors, and calibration procedures for the specific analytes of interest. Any listed chemical is a potential method interference when it is not a target analyte.

Delayed Fluorescence Imaging of Photosynthesis Inhibitor and Heavy Metal Induced Stress in Potato
Cent. Eur. J. Biol. • 7(3) • 2012 • 531-541 DOI: 10.2478/s11535-012-0038-z Central European Journal of Biology Delayed fluorescence imaging of photosynthesis inhibitor and heavy metal induced stress in potato Research Article Jaka Razinger1,*, Luka Drinovec2, Maja Berden-Zrimec3 1Agricultural Institute of Slovenia, 1000 Ljubljana, Slovenia 2Aerosol d.o.o., 1000 Ljubljana, Slovenia 3Institute of Physical Biology, 1000 Ljubljana, Slovenia Received 09 November 2011; Accepted 13 March 2012 Abstract: Early chemical-induced stress in Solanum tuberosum leaves was visualized using delayed fluorescence (DF) imaging. The ability to detect spatially heterogeneous responses of plant leaves exposed to several toxicants using delayed fluorescence was compared to prompt fluorescence (PF) imaging and the standard maximum fluorescence yield of PSII measurements (Fv/Fm). The toxicants used in the study were two photosynthesis inhibitors (herbicides), 100 μM methyl viologen (MV) and 140 μM diuron (DCMU), and two heavy metals, 100 μM cadmium and 100 μM copper. The exposure times were 5 and 72 h. Significant photosynthesis-inhibitor effects were already visualized after 5 h. In addition, a significant reduction in the DF/PF index was measured in DCMU- and MV-treated leaves after 5 h. In contrast, only DCMU-treated leaves exhibited a significant decrease in Fv/Fm after 5 h. All treatments resulted in a significant decrease in the DF/PF parameter after 72 h of exposure, when only MV and Cd treatment resulted in visible symptoms. Our study highlights the power of delayed fluorescence imaging. Abundant quantifiable spatial information was obtained with the instrumental setup. Delayed fluorescence imaging has been confirmed as a very responsive and useful technique for detecting stress induced by photosynthesis inhibitors or heavy metals. -
