Pesticide Standards Reference Guide Pesticide Standards Reference Guide AccuStandard® Over 1,000 Standards from Abamectin to Ziram Pesticide Desk Reference Guide This guide includes the following information (if available) Updated ■ Chemical name ■ Structure ■ CAS number ■ Molecular formula ■ Molecular weight ■ Physical state Included for most: ■ Solvent solubility ■ Specific gravity ■ Melting or Boiling point ■ Flash point ■ Common Synonyms Purchased Standards vs In-house Standards 1. Safety - Using solutions rather than neats reduces the laboratory personnel’s exposure to chemicals. Additionally, labs do not have to store and dispose of the neat materials. 2. Certification - Many laboratories are required to use independently produced reference standards. AccuStandard is accredited to ISO Guide 34 for the preparation and certification of reference materials. 3. Cost effective - Purchasing bulk bottles of pesicides, making the solution and disposing of the waste is usually more expensive than using a pre-made solution. Some pesticides may require a ColdPAK for shipping to preserve the integrity of the product.

The next character (an N or S) specifies whether the product is Neat or in Solution. 4. “-” with letters specify a solvent other than Methanol (MeOH). 5. “-” with a number followed by an X specifies the concentration difference from the 100 µg/mL (ex: -10X is 1000 µg/mL). Check for availability. Example: P-017S is Chlordane at 100 µg/mL in Methanol P-017N is Chlordane neat (10 mg) P-017S-H-10X is Chlordane at 1000 µg/mL in Hexane Key to symbols appearing in the table: in Acetone (-A) in Hexane (-H) in Toluene (-T) in Acetonitrile (-CN) in Isooctane (-TP) in Water (-W) in Ethyl acetate (-EA) in Methyl cellosolve (-MC) in Dimethyl sulfoxide (-DMSO) Can’t find a Pesticide? Search using CAS Numbers Index in back of the catalog. Purchasing Neat Pesticides There are two ways to purchase neat standards: Nominal weight and exact weight (see box below). For your standard preparation (nominal or exact), rinse the sample out of the vial and cap with solvent and dilute to achieve the desired concentration. Unless specified, neat samples are provided with nominal weights. Typically, the vial contains approximately 10% more of the product, however it is not known when you receive your standard what the exact amount is in the vial. Below is a standard procedure for re- moving all the neat material from the vial and determining the exact weight of the material in the vial. Small amounts (5-10 mg) of powder often are spread over the surface of the vial and cap. If the chemical is a liquid, it may coat the walls as a thin layer invisible to the eye. To recover all of the contents contained in a vial of neat material, please use the procedure described below: 1. Wipe the outside of the vial (containing the standard) clean and dry (including the cap). 2. Weigh the entire unit on an analytical balance. Record the weight to the nearest 0.1 mg. 3. Carefully transfer the contents to a volumetric flask using a suitable solvent. Rinse the cap and vial several times to assure a complete transfer. 4. Dry inside and outside of the vial and cap with mild heat or inert gas. 5. Weigh the empty dry vial on the same analytical balance to the nearest 0.1 mg and calculate by difference the amount of material transferred. Ordering Exact Weight for neat pesticides Neat pesticides are typically overfilled by approximately 10%, however, an exact weight is available for an additional charge. Specify X-WT when placing the order to take advantage of this service. A printout of the exact weight will be attached to the product label. Rinse the pesticide out of the vial with the desired solvent and dilute to volume to get a weight/volume standard. Custom Formulations 25-Plus Years Custom Formulation Experience Custom Standards are a cost and time saving alternative Custom pesticide formulations can be prepared for residue screening and other applications. QC options 1. Gravimetric/Volumetric Certification: Each compound is measured gravimetrically and QC verified instrumentally (where applicable). Every component in the Standard will be within +/- 0.5% of the requested value unless otherwise stated on the Certificate of Analysis. The solutions are diluted to volume using Class A glassware. A Certificate of Analysis accompanies each Standard and documents the gravimetric values. 2. Full Quantitative Certification: This QA/QC method includes extended GC, GC/MS or LC analysis using both internal calibration standards plus statistical analysis.

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.

    Türk. entomol. derg., 2020, 44 (4): 449-460 ISSN 1010-6960 DOI: http://dx.doi.org/10.16970/entoted.767482 E-ISSN 2536-491X Original article (Orijinal araştırma) Insecticide residue analyses in cucumbers sampled from Çanakkale open markets1 Çanakkale açık pazarlarından örneklenen hıyarlarda insektisit kalıntı analizleri Hayriye ÇATAK2 Osman TİRYAKİ3* Abstract The aim of this study was to investigate four insecticide residues in cucumbers with the aid of QuEChERS 2007.1 method. For method verification assessment, pesticide-free cucumber matrix was spiked with 0.1, 1 and 10 times of MRL for each pesticide. The QuEChERS-LC-MS/MS analytical method revealed that the detection limits of the insecticides were below the MRLs and the overall recovery of method was 97.7%. These figures were within the SANTE recovery limits (60-140%) and the values specified for the repeatability (≤20%). Cucumbers were collected from six different stands (A-F) at Çanakkale open markets for 6 weeks between 23 November and 28 December 2018. Residues of each sampling time and each stand were assessed. Acetamiprid residue of 257g and 236 µg/kg were detected in week 5 from stand B and in week 2 from stand E, respectively. These values are close to MRL (300 µg/kg). Formetanate hydrochloride residue of the week 3 from stand F (36.3 µg/kg) was more than MRL of 10 µg/kg. Pirimiphos methyl and chlorpyrifos residues were not detected in cucumbers. Theoretical maximum daily intake assessment showed that there was no chronic exposure risk for these four pesticides through cucumber consumption.

  • Greenhouse and Field Evaluation of Isoxaflutole for Weed Control In
    www.nature.com/scientificreports OPEN Greenhouse and field evaluation of isoxaflutole for weed control in maize in China Received: 27 June 2017 Ning Zhao, Lan Zuo, Wei Li, Wenlei Guo, Weitang Liu & Jinxin Wang Accepted: 18 September 2017 Greenhouse and field studies were conducted to provide a reference for pre-emergence (PRE) Published: xx xx xxxx application of isoxaflutole on maize in China. In greenhouse study, the isoxaflutole PRE application at 30 g active ingredient (a.i.) ha−1 could effectively control large numbers of weeds, especially some large-seeded broadleaves, tested in this study. The tolerance results indicated 21 maize hybrids showed different responses to isoxaflutole under greenhouse conditions. In 2015 and 2016, field experiments were conducted to determine and compare the weed control efficacy and safety to Zhengdan 958 maize with 6 herbicide treatments. In both years, isoxaflutole PRE at 100 to 250 g a.i. ha−1 was sufficient to provide satisfactory full-season control of the dominant common broadleaf and grass weeds in the field. Temporary injury to maize was observed with isoxaflutole treatments of 125, 150, and 250 g a.i. ha−1 in both years, but plants recovered within 4 to 6 wk. To maximize maize yield and provide satisfactory weed control, a range of 100 to 150 g a.i. ha−1 of isoxaflutole is recommended, depending on the soil characteristics, weather, and weed species present at the experimental site. Based on the results, isoxaflutole PRE has good potential for weed control in maize in China. Maize was planted on more hectares than any other crops in China from 2010 to 2014, with an average of 35 million ha planted per year and yield averaging 5,779 kg per ha per year1.

Complex for- (Freundlich model) and sorption paralleled organic C (OC) content. mation and subsequent sorption may partially account All tillage by depth combinations of soil exhibited a time-dependent for increased acifluorfen sorption with decreasing soil approach to sorption equilibrium that was well described by a two- pH or increasing cation exchange capacity (Pusino et site equilibrium±kinetic model.
