Mass Spectrometry in Authentication and Forensic Approaches for Determining the Origin of Hazardous Chemicals

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Identification of a chemical agent yields insights into its physicochemical properties. By examining the intrinsic characteristics and environment of a compound, information about its history can be gathered. The main objective of authentication/forensic approaches to chemicals is to trace the history of the compound's origin, regardless of ...

Host resistance modulates in planta efficacy of seed‐applied fluxapyroxad against spot form net blotch in barley

Pest Management Science, EarlyView.
Barley variety influences fluxapyroxad efficacy by affecting distribution and dissipation of the active ingredient, with plant biomass contributing to these differences. Abstract BACKGROUND Seed‐applied fungicides are used to protect barley seedlings from spot form net blotch, caused by Pyrenophora teres f. maculata, among other diseases.

Evaluating larvicide performance against Culicoides sonorensis in semi‐field conditions

Pest Management Science, EarlyView.
This study evaluated the efficacy of larvicide products against Culicoides sonorensis populations under controlled semi‐field conditions. Larvicide efficacy against C. sonorensis declined over time, in different environmental conditions. In particular, precipitation and habitat disturbance influenced residual performance. Abstract BACKGROUND Culicoides
