Chemical Control of Phytophthora sojae: Sensitivity of Isolates and Effects on Soybean Seed Germination and Seed Rot

Journal of Phytopathology, Volume 174, Issue 5, September/October 2026.
ABSTRACT Phytophthora sojae is an oomycete responsible for causing seedling damping‐off and root and stem rot in soybean. Seed treatment with chemical products is one of the management strategies that can be used to control the disease. Thus, the objective of this study was to evaluate the in vitro sensitivity of P.

Field trial investigating the efficacy of a long-acting imidacloprid 10%/flumethrin 4.5% polymer matrix collar (Seresto®, Elanco) compared to monthly topical fipronil for the chemoprevention of canine tick-borne pathogens in Cambodia

Current Research in Parasitology and Vector-Borne Diseases, 2022
The tropical brown dog tick, Rhipicephalus linnaei, commonly infests canines in the tropics and is an important vector for disease-causing and sometimes lethal pathogens including Babesia spp., Ehrlichia canis, Hepatozoon canis and Anaplasma platys.

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

Chemistry – A European Journal, Volume 32, Issue 26, 11 July 2026.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

Synthesis of 2‐Aza‐Bicyclo[4.3.0]nonane Derivatives Related to the Camporidines via Intramolecular [3+2]‐Cycloaddition

European Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.
The intramolecular nitrile oxide olefin [3 + 2]‐cycloaddition offers a reliable entry toward 2‐aza‐bicyclo[4.3.0]‐nonanes, a substructure found in several bioactive piperidine alkaloids. The required oxime precursors were prepared in non‐racemic form by Ir‐catalyzed asymmetric allylation and ring‐closing metathesis.
