First genome sequence of a European Alternaria brassicae isolate and genes involved in early development of alternaria leaf spot on Brassica juncea

Pest Management Science, EarlyView.
This article reports the first genome sequence of a UK Alternaria brassicae isolate. Dual RNA‐sequencing profiling of A. brassicae‐infected Brassica juncea leaves identified differentially expressed genes involved in pathogenicity and host response pathways in moderately resistant Sej‐2 (2) and moderately susceptible Pusa Jaikisan cultivars.

Determining frequencies of fungicide resistance in Leptosphaeria maculans that render demethylation inhibitor fungicides ineffective in the field

Pest Management Science, EarlyView.
As little as 1–10% of the population is needed to be resistant for demethylation inhibitor fungicides to be rendered ineffective. Following a single round of selection, the frequency increases by more than 15% with limited fitness penalty detected when no selection is present.

Alternaria tenuissima Causing Alternaria Blight on Pigeonpea in India

Plant Disease, 2012
Pigeonpea (Cajanus cajan (L.) Millsp.) is a major grain legume of the tropics and subtropics worldwide. In India, pigeonpea is the third most important food legume after chickpea and field pea. Blight symptoms on pigeonpea were observed in alarming proportion during the 2009 through 2011 crop seasons in Andhra Pradesh state in India. Disease incidence

How does leaf age affect performance? A comparative study of essential oils from young and mature Eucalyptus globulus leaves in crop protection

Pest Management Science, EarlyView.
Leaf age influences metabolomic profiling but not bioactivity of Eucalyptus globulus essential oils. Leaf age affects volatile levels of young and adult E. globulus oils, but not their bioactivity. Young leaf essential oil had higher contents of α‐ and β‐pinene. AEEO had higher levels of 1,8‐cineole and trans‐pinocarveol.

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

Pest Management Science, EarlyView.
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 ...
