Comparative toxicity of fumigants and a phosphine synergist using a novel containment chamber for the safe generation of concentrated phosphine gas. [PDF]
With the phasing out of ozone-depleting substances in accordance with the United Nations Montreal Protocol, phosphine remains as the only economically viable fumigant for widespread use.

Screening of phosphine resistance in Sitophilus oryzae (L.) (rice weevil) populations in Turkey
In this study, the status and prevalence of phosphine resistance in Sitophilus oryzae (L.) (Coleoptera: Curculionidae) populations collected from Mersin and Konya Province in Turkey were investigated by conducting the discrimination concentration tests ...

Inheritance and characterization of strong resistance to phosphine in Sitophilus oryzae (L.). [PDF]
Sitophilus oryzae (Linnaeus) is a major pest of stored grain across Southeast Asia and is of increasing concern in other regions due to the advent of strong resistance to phosphine, the fumigant used to protect stored grain from pest insects.

Gene interactions constrain the course of evolution of phosphine resistance in the lesser grain borer, Rhyzopertha dominica [PDF]
Phosphine, a widely used fumigant for the protection of stored grain from insect pests, kills organisms indirectly by inducing oxidative stress. High levels of heritable resistance to phosphine in the insect pest of stored grain, Rhyzopertha dominica ...

Phosphine-Based Z‑Selective Ruthenium Olefin Metathesis Catalysts
Whereas a number of highly Z-selective ruthenium-based olefin metathesis catalysts bearing N-heterocyclic carbene ligands have been reported in recent years, Z-selectivity has so far been difficult to achieve for phosphine-based catalysts.
