Field Studies for Pesticide Registration: Efficacy and Residue in GLP (Lecture in AgroChemEx), 17° Siconbiol (BioControl Symposium) and IV Workshop of Adjuvants. 24/07 - 04/08.

Plant biostimulants are regulated differently worldwide. The USDA defines biostimulants as substances that enhance natural plant processes independently of nutrient content, improving nutrient use efficiency, stress tolerance, and crop quality. Technology developers must register their plant biostimulant products based on composition and intended use. They can register as a fertilizer, soil amendment, beneficial substance, or inoculum at the state level. Alternatively, they can register as a plant regulator (i.e., pesticide) with the United States Environmental Protection Agency (EPA). State fertilizer regulations require minimal data, while EPA registration demands safety and composition information under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Although efficacy data submission is not always required, the EPA reserves the right to request it on a case-by-case basis. Register now for ACI's US Biostimulants Summit 2024, taking place on 10th & 11th July 2024 in St Louis, Missouri, USA to hear from Grower's Research and Innovation Network (GRIN). GRIN will be represented by: Vishal Shinde. Dr Shinde will be joining Session 1 on Day 1: Verifying the legitimacy and credibility of biostimulants products and will present: Assessing the development of efficiency data to prove biostimulants products are doing what they claim.

Source: Analytical methods : advancing methods and applications A new method combining QuEChERS and UPLC-MS/MS was developed to simultaneously detect 78 pesticides and 16 mycotoxins in tsampa. The method showed good correlation, low detection limits, and high recoveries. It was applied to real samples and proved to be efficient and applicable for monitoring pesticide and mycotoxin levels in tsampa.

📢 Excited to announce the publication of our recent article on "Flexible Filter Paper Substrates for Rapid Pesticide Detection via Surface-enhanced Raman Scattering (SERS)"! 📚✨ The residue of methyl parathion (MP) pesticide on agricultural products poses health risks, making its detection crucial. Our study showcases the use of surface-enhanced Raman spectroscopy (SERS) as a fast, reliable, and accurate technique for trace pesticide detection. We employed filter paper substrates (FPS) coated with gold nanoparticles (AuNPs) as SERS-active sensors for MP identification. By fabricating AuNPs through a simple chemical reduction method and dropwise coating them on FPS, we developed flexible SERS-active substrates (Flex-SERS-Subs) capable of detecting MP's molecular vibrations. Our method achieved an impressive limit of detection (LOD) of 10^-12 M, with a calculated relative standard deviation (RSD) of 3.39% for ten repeated measurements. This research presents a cost-effective and efficient approach for detecting trace pesticides, with promising outcomes for future investigations. The developed Flex-SERS-Subs offer a simpler, faster, and more affordable solution compared to existing techniques. Furthermore, we envision the potential development of similar sensors for the detection of various biological substances. Congratulations to the team involved in this study! 🎉🔬 Atefe Mohsennezhad Amin Hadi Vahid Eskandari Saeideh Mehmandoust #researchpublication #SERS #pesticides #nanotechnology #ramanspectroscopy #healthissues #infertility

"End co-formulant secrecy" •Pesticide formulations contain both active ingredients and co-formulants. Both can cause toxicity to non-target organisms. •Under European Union and United States law, the details of the co-formulant composition are not publicly disclosed. •This limits the capacity for researchers to understand and test their impacts on non-target organisms. •The rationale for secrecy is to protect innovation, but this is ineffective and patent law already protects innovation. •Consumers and pesticide end users deserve to have transparency as to what is included in pesticide products. #Agriculture #Pesticide #Herbicide #Glyphosate #Food https://lnkd.in/evxrp-Fz

🔥 Out-of-the box solutions for fast, more confident pesticide residues analysis🔥 There are many analytical challenges with pesticide residue analysis, as it involves an ever-growing list of chemically diverse compounds. Given the wide variety of solutions available, choosing the best workflow to fit your laboratory’s unique needs can present yet another challenge. Follows the concept by Ternes et al., 2006. Domains of GC-MS and LC-MS techniques in the two dimensions of hydrophobicity and volatility. The domains are increasingly overlapped with the advance of atmospheric pressure techniques for both LC and GC-MS (As attached chart). LC-MS/MS and GC-MS/MS are becoming common analytical techniques in Pesticide Analysis. Using the recommended configuration, pre-defined workflows enable robust analysis of pesticide residues in food with LC-MS/MS and/or GC-MS/MS systems, controlled by a single software platform. Enabling dual sequence processing, data can be merged to provide orthogonal cross-confirmation of identity, supporting compliance with SANTE analytical quality control criteria. Reduce time spent on data review with customizable view settings, report templates, and flexible filter and flagging options, enabling you to focus review on relevant injections and lowering your training and maintenance efforts. Attend the Webinar https://lnkd.in/gmSfXY4d to learn a brand-new approach by Pesticide Smart Kit, designed to ease those challenges and drive efficiency with one of seven (7) high-performance workflows.

Sharing our latest research on pesticide residue quantification in food using mass spectrometry.   Over 4 years, we collected GC and LC-MS/MS data from the Phytopharmacy Laboratory in Lebanon. Using pairwise correlation, we identified four compounds for the LC dataset and seven for the GC dataset, that could be used to quantify up to 66 and 96 pesticides on LC and GC, respectively. We developed a linear regression model to estimate the calibration slope of each of the target pesticides.   Inspired by the necessity to minimize resource requirements, our approach significantly reduces resource demands while ensuring precise quantification with minimal reference materials. This eliminates the need to purchase hundreds of analytical standards for pesticide residue quantification in food.   I am very pleased with this collaboration with my friends Yota (Panagiota) Katsikouli and Amal Kobeissy.   For more details, check our paper.   #Pesticides #FoodSafety #Statistics #MassSpectrometry #Sustainability
