Pest Management Science, EarlyView.Presence and abundance of Botryosphaeria dieback inoculum were determined using spore trapping and droplet digital polymerase chain reaction in British Columbia, Canada. Highest inoculum was recorded in spring (April–June) and again in summer (July–September). These results suggest early pruning in December–January can mitigate pruning wound infections.

Journal of Applied Entomology, EarlyView.ABSTRACT The planthopper Pentastiridius leporinus (Hemiptera: Cixiidae) is the primary vector of two phloem‐restricted prokaryotes, which can cause the disease syndrome de basses richesses (SBR) in sugar beet (Beta vulgaris L.). Heavy infestations of this insect have contributed to significant yield losses in Central Europe, but little is known about ...

Journal of Applied Entomology, EarlyView.ABSTRACT Jikradia olitoria Say is a Nearctic leafhopper that was recently reported in several European countries. Given its role as the vector of phytoplasmas associated with Grapevine Yellows diseases (GYD) in its native range, its presence in European vineyard agroecosystems could represent an important phytosanitary risk.

Silencing of CrNPR1 and CrNPR3 Alters Plant Susceptibility to Periwinkle Leaf Yellowing Phytoplasma
Frontiers in Plant Science, 2019 Phytoplasmas are prokaryotic plant pathogens that cause considerable loss in many economically important crops, and an increasing number of phytoplasma diseases are being reported on new hosts. Knowledge of plant defense mechanisms against such pathogens

Plant, Cell &Environment, EarlyView.ABSTRACT Plants frequently encounter multiple pathogens concurrently, yet the molecular bases of pathogen–pathogen interactions during mixed infections remain largely unresolved. Here we show that co‐infection of rice by Rice orange leaf phytoplasma (ROLP) and Rice stripe mosaic virus (RSMV) markedly suppresses RSMV proliferation in both host plants ...
