Changing straw management practices in California rice fields: A recent and historical analysis of the Sacramento Valley

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Agricultural practices are constantly evolving due to changes in regulation, climate, and technology. Regulations in California resulted in phasing out rice (Oryza sativa L.) straw burning in the 1990s, leading to a range of alternative practices to manage the straw, which impact agronomic practices, air quality, ecosystem services, and ...

Alcoholic extracts of Russian sage (Salvia yangii) contain bioactive terpenoids with inhibitory activity against grapevine downy mildew (Plasmopara viticola)

open access: yesPest Management Science, Volume 82, Issue 9, Page 8159-8170, September 2026.
Alcoholic extracts from flowers, leaves, and shoots of Russian sage decreased downy mildew severity on grapevine leaf disks. Fractionation followed by metabolomic analysis revealed putative terpenoids as the main components of the active fractions. Specifically, 7‐methylrosmanol, 12‐O‐methylcarnosic acid, carnosic acid, and carnosol were identified as ...

Host‐associated chemical cues mediating host‐finding behaviour in the larval ectoparasitoid Cephalonomia tarsalis

open access: yesPest Management Science, Volume 82, Issue 9, Page 8459-8467, September 2026.
Host‐associated volatiles mediate host location in Cephalonomia tarsalis, with faecal odours from fourth‐instar larvae, particularly 1‐pentadecene, attracting females and supporting the biological control of stored‐product pest beetles. Abstract BACKGROUND Understanding how parasitoids locate their hosts is essential for improving the effectiveness of ...

Stability studies of cynaropicrin–major sesquiterpene lactone of Cynara cardunculus leaves

open access: yesPest Management Science, Volume 82, Issue 9, Page 8820-8830, September 2026.
This study investigated its stability under high temperature and pH, mimicking agronomic extremes and under soil context. Bioassays demonstrated that degradation products exhibited higher phytotoxic activity than cynaropicrin and deacylcynaropicrin. This is the first study about cynaropicrin's stability, characterizing degradation products, and their ...
